Emit LLVM optimization remarks when enabled with `-Cremark` The default diagnostic handler considers all remarks to be disabled by default unless configured otherwise through LLVM internal flags: `-pass-remarks`, `-pass-remarks-missed`, and `-pass-remarks-analysis`. This behaviour makes `-Cremark` ineffective on its own. Fix this by configuring a custom diagnostic handler that enables optimization remarks based on the value of `-Cremark` option. With `-Cremark=all` enabling all remarks.

rustc: Optimize reading metadata by 4x We were previously reading metadata via `ar p`, but as learned from rustdoc awhile back, spawning a process to do something is pretty slow. Turns out LLVM has an Archive class to read archives, but it cannot write archives. This commits adds bindings to the read-only version of the LLVM archive class (with a new type that only has a read() method), and then it uses this class when reading the metadata out of rlibs. When you put this in tandem of not compressing the metadata, reading the metadata is 4x faster than it used to be The timings I got for reading metadata from the respective libraries was: libstd-04ff901e-0.9-pre.dylib => 100ms libstd-04ff901e-0.9-pre.rlib => 23ms librustuv-7945354c-0.9-pre.dylib => 4ms librustuv-7945354c-0.9-pre.rlib => 1ms librustc-5b94a16f-0.9-pre.dylib => 87ms librustc-5b94a16f-0.9-pre.rlib => 35ms libextra-a6ebb16f-0.9-pre.dylib => 63ms libextra-a6ebb16f-0.9-pre.rlib => 15ms libsyntax-2e4c0458-0.9-pre.dylib => 86ms libsyntax-2e4c0458-0.9-pre.rlib => 22ms In order to always take advantage of these faster metadata read-times, I sort the files in filesearch based on whether they have an rlib extension or not (prefer all rlib files first). Overall, this halved the compile time for a `fn main() {}` crate from 0.185s to 0.095s on my system (when preferring dynamic linking). Reading metadata is still the slowest pass of the compiler at 0.035s, but it's getting pretty close to linking at 0.021s! The next best optimization is to just not copy the metadata from LLVM because that's the most expensive part of reading metadata right now.

Band-aid fix to stop race conditions in llvm errors This is a big hammer, but should be effective at completely removing a few issues, including inconsistent error messages and segfaults when LLVM workers race to report results LLVM_THREAD_LOCAL has been present in LLVM since 8 months before 3.7 (the earliest supported LLVM version that Rust can use) Maybe fixes #43402 (third time lucky?)

rustllvm: Only initialize command-line arguments once In my WIP on rustpkg, I was calling driver code that calls LLVMRustWriteOutputFile more than once. This was making LLVM unhappy, since that function has code that initializes the command-line options for LLVM, and I guess you can't do that more than once. So, check if they've already been initialized.

This gives rustc the same stack smash protection support as clang offers through options `-fno-stack-protector`, `-fstack-protector`, `-fstack-protector-strong`, and `-fstack-protector-all`. The protection this can offer is demonstrated in test/ui/abi/stack-protector.rs. This fills a gap in the current list of rustc exploit mitigations (https://doc.rust-lang.org/rustc/exploit-mitigations.html), originally discussed in #15179. Stack smash protection adds runtime overhead and is therefore still off by default, but now users have the option to trade performance for security as they see fit. An example use case is adding Rust code in an existing C/C++ code base compiled with stack smash protection. Without the ability to add stack smash protection to the Rust code, the code base artifacts could be exploitable in ways not possible if the code base remained pure C/C++. Stack smash protection support is present in LLVM for almost all the current tier 1/tier 2 targets: see test/assembly/stack-protector/stack-protector-target-support.rs. The one exception is nvptx64-nvidia-cuda. This patch follows clang's example, and adds a warning message printed if stack smash protection is used with this target (see test/ui/stack-protector/warn-stack-protector-unsupported.rs). Support for tier 3 targets has not been checked. Since the heuristics are applied at the LLVM level, the heuristics are expected to add stack smash protection to a fraction of functions comparable to C/C++. Some experiments demonstrating how Rust code is affected by the different heuristics can be found in test/assembly/stack-protector/stack-protector-heuristics-effect.rs. There is potential for better heuristics using Rust-specific safety information. For example it might be reasonable to skip stack smash protection in functions which transitively only use safe Rust code, or which uses only a subset of functions the user declares safe (such as anything under `std.*`). Such alternative heuristics could be added at a later point. LLVM also offers a "safestack" sanitizer as an alternative way to guard against stack smashing (see #26612). This could possibly also be included as a stack-protection heuristic. An alternative is to add it as a sanitizer (#39699). This is what clang does: safestack is exposed with option `-fsanitize=safe-stack`. The options are only supported by the LLVM backend, but as with other codegen options it is visible in the main codegen option help menu. The heuristic names "basic", "strong", and "all" are hopefully sufficiently generic to be usable in other backends as well. Reviewed-by: Nikita Popov <nikic@php.net> Extra commits during review: - [address-review] make the stack-protector option unstable - [address-review] reduce detail level of stack-protector option help text - [address-review] correct grammar in comment - [address-review] use compiler flag to avoid merging functions in test - [address-review] specify min LLVM version in fortanix stack-protector test Only for Fortanix test, since this target specifically requests the `--x86-experimental-lvi-inline-asm-hardening` flag. - [address-review] specify required LLVM components in stack-protector tests - move stack protector option enum closer to other similar option enums - rustc_interface/tests: sort debug option list in tracking hash test - add an explicit `none` stack-protector option Revert "set LLVM requirements for all stack protector support test revisions" This reverts commit a49b74f92a4e7d701d6f6cf63d207a8aff2e0f68.

Apply noundef attribute to &T, &mut T, Box<T>, bool This doesn't handle `char` because it's a bit awkward to distinguish it from u32 at this point in codegen. Note that for some types (like `&Struct` and `&mut Struct`), we already apply `dereferenceable`, which implies `noundef`, so the IR does not change.

codegen: use new {re,de,}allocator annotations in llvm This obviates the patch that teaches LLVM internals about _rust_{re,de}alloc functions by putting annotations directly in the IR for the optimizer. The sole test change is required to anchor FileCheck to the body of the `box_uninitialized` method, so it doesn't see the `allocalign` on `__rust_alloc` and get mad about the string `alloca` showing up. Since I was there anyway, I added some checks on the attributes to prove the right attributes got set. While we're here, we also emit allocator attributes on __rust_alloc_zeroed. This should allow LLVM to perform more optimizations for zeroed blocks, and probably fixes #90032. [This comment](https://github.com/rust-lang/rust/issues/24194#issuecomment-308791157) mentions "weird UB-like behaviour with bitvec iterators in rustc_data_structures" so we may need to back this change out if things go wrong. The new test cases require LLVM 15, so we copy them into LLVM 14-supporting versions, which we can delete when we drop LLVM 14.

Use llvm::Attribute API instead of "raw value" APIs, which will be removed in LLVM 4.0. The librustc_llvm API remains mostly unchanged, except that llvm::Attribute is no longer a bitflag but represents only a *single* attribute. The ability to store many attributes in a small number of bits and modify them without interacting with LLVM is only used in rustc_trans::abi and closely related modules, and only attributes for function arguments are considered there. Thus rustc_trans::abi now has its own bit-packed representation of argument attributes, which are translated to rustc_llvm::Attribute when applying the attributes.

Add intrinsics for float arithmetic with `fast` flag enabled `fast` a.k.a UnsafeAlgebra is the flag for enabling all "unsafe" (according to llvm) float optimizations. See LangRef for more information http://llvm.org/docs/LangRef.html#fast-math-flags Providing these operations with less precise associativity rules (for example) is useful to numerical applications. For example, the summation loop: let sum = 0.; for element in data { sum += *element; } Using the default floating point semantics, this loop expresses the floats must be added in a sequence, one after another. This constraint is usually completely unintended, and it means that no autovectorization is possible.

codegen_llvm: check inline assembly constraints with LLVM LLVM provides a way of checking whether the constraints and the actual inline assembly make sense. This commit introduces a check before emitting code for the inline assembly. If LLVM rejects the inline assembly (or its constraints), then the compiler emits an error E0668 ("malformed inline assembly"). Signed-off-by: Levente Kurusa <lkurusa@acm.org>

rustc: Update LLVM This commit updates the LLVM submodule in use to the current HEAD of the LLVM repository. This is primarily being done to start picking up unwinding support for MSVC, which is currently unimplemented in the revision of LLVM we are using. Along the way a few changes had to be made: * As usual, lots of C++ debuginfo bindings in LLVM changed, so there were some significant changes to our RustWrapper.cpp * As usual, some pass management changed in LLVM, so clang was re-scrutinized to ensure that we're doing the same thing as clang. * Some optimization options are now passed directly into the `PassManagerBuilder` instead of through CLI switches to LLVM. * The `NoFramePointerElim` option was removed from LLVM, favoring instead the `no-frame-pointer-elim` function attribute instead. Additionally, LLVM has picked up some new optimizations which required fixing an existing soundness hole in the IR we generate. It appears that the current LLVM we use does not expose this hole. When an enum is moved, the previous slot in memory is overwritten with a bit pattern corresponding to "dropped". When the drop glue for this slot is run, however, the switch on the discriminant can often start executing the `unreachable` block of the switch due to the discriminant now being outside the normal range. This was patched over locally for now by having the `unreachable` block just change to a `ret void`.

rustc: Start implementing compat with LLVM 9 This commit doesn't actually migrate to LLVM 9, but it brings our own C++ bindings in line with LLVM 9 and able to compile against tip of tree. The changes made were: * The `MainSubprogram` flag for debuginfo moved between flag types. * Iteration of archive members was tweaked slightly and we have to construct the two iterators before constructing the returned `RustArchiveIterator` value. * The `getOrInsertFunction` binding now returns a wrapper which we use `getCallee()` on to get the value we're interested in.

Use error-on-mismatch policy for PAuth module flags. This agrees with Clang, and avoids an error when using LTO with mixed C/Rust. LLVM considers different behaviour flags to be a mismatch, even when the flag value itself is the same. This also makes the flag setting explicit for all uses of LLVMRustAddModuleFlag.

Add metadata generation for vtables when using VFE This adds the typeid and `vcall_visibility` metadata to vtables when the -Cvirtual-function-elimination flag is set. The typeid is generated in the same way as for the `llvm.type.checked.load` intrinsic from the trait_ref. The offset that is added to the typeid is always 0. This is because LLVM assumes that vtables are constructed according to the definition in the Itanium ABI. This includes an "address point" of the vtable. In C++ this is the offset in the vtable where information for RTTI is placed. Since there is no RTTI information in Rust's vtables, this "address point" is always 0. This "address point" in combination with the offset passed to the `llvm.type.checked.load` intrinsic determines the final function that should be loaded from the vtable in the `WholeProgramDevirtualization` pass in LLVM. That's why the `llvm.type.checked.load` intrinsics are generated with the typeid of the trait, rather than with that of the function that is called. This matches what `clang` does for C++. The vcall_visibility metadata depends on three factors: 1. LTO level: Currently this is always fat LTO, because LLVM only supports this optimization with fat LTO. 2. Visibility of the trait: If the trait is publicly visible, VFE can only act on its vtables after linking. 3. Number of CGUs: if there is more than one CGU, also vtables with restricted visibility could be seen outside of the CGU, so VFE can only act on them after linking. To reflect this, there are three visibility levels: Public, LinkageUnit, and TranslationUnit.

rustc: Start implementing compat with LLVM 9 This commit doesn't actually migrate to LLVM 9, but it brings our own C++ bindings in line with LLVM 9 and able to compile against tip of tree. The changes made were: * The `MainSubprogram` flag for debuginfo moved between flag types. * Iteration of archive members was tweaked slightly and we have to construct the two iterators before constructing the returned `RustArchiveIterator` value. * The `getOrInsertFunction` binding now returns a wrapper which we use `getCallee()` on to get the value we're interested in.

Fix DWARF generation for enums The DWARF generated for Rust enums was always somewhat unusual. Rather than using DWARF constructs directly, it would emit magic field names like "RUST$ENCODED$ENUM$0$Name" and "RUST$ENUM$DISR". Since PR #45225, though, even this has not worked -- the ad hoc scheme was not updated to handle the wider variety of niche-filling layout optimizations now available. This patch changes the generated DWARF to use the standard tags meant for this purpose; namely, DW_TAG_variant and DW_TAG_variant_part. The patch to implement this went in to LLVM 7. In order to work with older versions of LLVM, and because LLVM doesn't do anything here for PDB, the existing code is kept as a fallback mode. Support for this DWARF is in the Rust lldb and in gdb 8.2. Closes #32920 Closes #32924 Closes #52762 Closes #53153

Implement an `address_insignificant` attribute This can be applied to statics and it will indicate that LLVM will attempt to merge the constant in .data with other statics. I have preliminarily applied this to all of the statics generated by the new `ifmt!` syntax extension. I compiled a file with 1000 calls to `ifmt!` and a separate file with 1000 calls to `fmt!` to compare the sizes, and the results were: fmt 310k ifmt (before) 529k ifmt (after) 202k This now means that ifmt! is both faster and smaller than fmt!, yay!

Implement LTO This commit implements LTO for rust leveraging LLVM's passes. What this means is: * When compiling an rlib, in addition to insdering foo.o into the archive, also insert foo.bc (the LLVM bytecode) of the optimized module. * When the compiler detects the -Z lto option, it will attempt to perform LTO on a staticlib or binary output. The compiler will emit an error if a dylib or rlib output is being generated. * The actual act of performing LTO is as follows: 1. Force all upstream libraries to have an rlib version available. 2. Load the bytecode of each upstream library from the rlib. 3. Link all this bytecode into the current LLVM module (just using llvm apis) 4. Run an internalization pass which internalizes all symbols except those found reachable for the local crate of compilation. 5. Run the LLVM LTO pass manager over this entire module 6a. If assembling an archive, then add all upstream rlibs into the output archive. This ignores all of the object/bitcode/metadata files rust generated and placed inside the rlibs. 6b. If linking a binary, create copies of all upstream rlibs, remove the rust-generated object-file, and then link everything as usual. As I have explained in #10741, this process is excruciatingly slow, so this is *not* turned on by default, and it is also why I have decided to hide it behind a -Z flag for now. The good news is that the binary sizes are about as small as they can be as a result of LTO, so it's definitely working. Closes #10741 Closes #10740

Issue #3511 - Rationalize temporary lifetimes. Major changes: - Define temporary scopes in a syntax-based way that basically defaults to the innermost statement or conditional block, except for in a `let` initializer, where we default to the innermost block. Rules are documented in the code, but not in the manual (yet). See new test run-pass/cleanup-value-scopes.rs for examples. - Refactors Datum to better define cleanup roles. - Refactor cleanup scopes to not be tied to basic blocks, permitting us to have a very large number of scopes (one per AST node). - Introduce nascent documentation in trans/doc.rs covering datums and cleanup in a more comprehensive way.

rustllvm: Add LLVMRustArrayType LLVM internally uses `uint64_t` for array size, but the corresponding C API (`LLVMArrayType`) uses `unsigned int` so ths value is truncated. Therefore rustc generates wrong type for fixed-sized large vector e.g. `[0 x i8]` for `[0u8, ..(1 << 32)]`. This patch adds `LLVMRustArrayType` function for `uint64_t` support.

rustllvm: Add LLVMRustArrayType LLVM internally uses `uint64_t` for array size, but the corresponding C API (`LLVMArrayType`) uses `unsigned int` so ths value is truncated. Therefore rustc generates wrong type for fixed-sized large vector e.g. `[0 x i8]` for `[0u8, ..(1 << 32)]`. This patch adds `LLVMRustArrayType` function for `uint64_t` support.

rustc_trans: Update LLVMBuildLandingPad signature The C API of this function changed so it no longer takes a personality function. A shim was introduced to call the right LLVM function (depending on which version we're compiled against) to set the personality function on the outer function. The compiler only ever sets one personality function for all generated functions, so this should be equivalent.

trans: Reimplement unwinding on MSVC This commit transitions the compiler to using the new exception handling instructions in LLVM for implementing unwinding for MSVC. This affects both 32 and 64-bit MSVC as they're both now using SEH-based strategies. In terms of standard library support, lots more details about how SEH unwinding is implemented can be found in the commits. In terms of trans, this change necessitated a few modifications: * Branches were added to detect when the old landingpad instruction is used or the new cleanuppad instruction is used to `trans::cleanup`. * The return value from `cleanuppad` is not stored in an `alloca` (because it cannot be). * Each block in trans now has an `Option<LandingPad>` instead of `is_lpad: bool` for indicating whether it's in a landing pad or not. The new exception handling intrinsics require that on MSVC each `call` inside of a landing pad is annotated with which landing pad that it's in. This change to the basic block means that whenever a `call` or `invoke` instruction is generated we know whether to annotate it as part of a cleanuppad or not. * Lots of modifications were made to the instruction builders to construct the new instructions as well as pass the tagging information for the call/invoke instructions. * The translation of the `try` intrinsics for MSVC has been overhauled to use the new `catchpad` instruction. The filter function is now also a rustc-generated function instead of a purely libstd-defined function. The libstd definition still exists, it just has a stable ABI across architectures and leaves some of the really weird implementation details to the compiler (e.g. the `localescape` and `localrecover` intrinsics).

Add LLVM KCFI support to the Rust compiler This commit adds LLVM Kernel Control Flow Integrity (KCFI) support to the Rust compiler. It initially provides forward-edge control flow protection for operating systems kernels for Rust-compiled code only by aggregating function pointers in groups identified by their return and parameter types.

trans: Reimplement unwinding on MSVC This commit transitions the compiler to using the new exception handling instructions in LLVM for implementing unwinding for MSVC. This affects both 32 and 64-bit MSVC as they're both now using SEH-based strategies. In terms of standard library support, lots more details about how SEH unwinding is implemented can be found in the commits. In terms of trans, this change necessitated a few modifications: * Branches were added to detect when the old landingpad instruction is used or the new cleanuppad instruction is used to `trans::cleanup`. * The return value from `cleanuppad` is not stored in an `alloca` (because it cannot be). * Each block in trans now has an `Option<LandingPad>` instead of `is_lpad: bool` for indicating whether it's in a landing pad or not. The new exception handling intrinsics require that on MSVC each `call` inside of a landing pad is annotated with which landing pad that it's in. This change to the basic block means that whenever a `call` or `invoke` instruction is generated we know whether to annotate it as part of a cleanuppad or not. * Lots of modifications were made to the instruction builders to construct the new instructions as well as pass the tagging information for the call/invoke instructions. * The translation of the `try` intrinsics for MSVC has been overhauled to use the new `catchpad` instruction. The filter function is now also a rustc-generated function instead of a purely libstd-defined function. The libstd definition still exists, it just has a stable ABI across architectures and leaves some of the really weird implementation details to the compiler (e.g. the `localescape` and `localrecover` intrinsics).

Use llvm::Attribute API instead of "raw value" APIs, which will be removed in LLVM 4.0. The librustc_llvm API remains mostly unchanged, except that llvm::Attribute is no longer a bitflag but represents only a *single* attribute. The ability to store many attributes in a small number of bits and modify them without interacting with LLVM is only used in rustc_trans::abi and closely related modules, and only attributes for function arguments are considered there. Thus rustc_trans::abi now has its own bit-packed representation of argument attributes, which are translated to rustc_llvm::Attribute when applying the attributes.

RustWrapper: adapt to APInt API changes in LLVM 15 In https://reviews.llvm.org/D125556 upstream changed sext() and zext() to allow some no-op cases, which previously required use of the *OrSelf() methods, which I assume is what was going on here. The *OrSelf() methods got removed in https://reviews.llvm.org/D125559 after two weeks of deprecation because they came with some bonus (probably-undesired) behavior. Since the behavior of sext() and zext() changed slightly, I kept the old *OrSelf() calls in LLVM 14 and earlier, and only use the new version in LLVM 15. r? @nikic

Fix incorrect LLVM Linkage enum The `Linkage` enum in librustc_llvm got out of sync with the version in LLVM and it caused two variants of the #[linkage=""] attribute to break. This adds the functions `LLVMRustGetLinkage` and `LLVMRustSetLinkage` which convert between the Rust Linkage enum and the LLVM one, which should stop this from breaking every time LLVM changes it. Fixes #33992

Use llvm::Attribute API instead of "raw value" APIs, which will be removed in LLVM 4.0. The librustc_llvm API remains mostly unchanged, except that llvm::Attribute is no longer a bitflag but represents only a *single* attribute. The ability to store many attributes in a small number of bits and modify them without interacting with LLVM is only used in rustc_trans::abi and closely related modules, and only attributes for function arguments are considered there. Thus rustc_trans::abi now has its own bit-packed representation of argument attributes, which are translated to rustc_llvm::Attribute when applying the attributes.

rustc: Enable LTO and multiple codegen units This commit is a refactoring of the LTO backend in Rust to support compilations with multiple codegen units. The immediate result of this PR is to remove the artificial error emitted by rustc about `-C lto -C codegen-units-8`, but longer term this is intended to lay the groundwork for LTO with incremental compilation and ultimately be the underpinning of ThinLTO support. The problem here that needed solving is that when rustc is producing multiple codegen units in one compilation LTO needs to merge them all together. Previously only upstream dependencies were merged and it was inherently relied on that there was only one local codegen unit. Supporting this involved refactoring the optimization backend architecture for rustc, namely splitting the `optimize_and_codegen` function into `optimize` and `codegen`. After an LLVM module has been optimized it may be blocked and queued up for LTO, and only after LTO are modules code generated. Non-LTO compilations should look the same as they do today backend-wise, we'll spin up a thread for each codegen unit and optimize/codegen in that thread. LTO compilations will, however, send the LLVM module back to the coordinator thread once optimizations have finished. When all LLVM modules have finished optimizing the coordinator will invoke the LTO backend, producing a further list of LLVM modules. Currently this is always a list of one LLVM module. The coordinator then spawns further work to run LTO and code generation passes over each module. In the course of this refactoring a number of other pieces were refactored: * Management of the bytecode encoding in rlibs was centralized into one module instead of being scattered across LTO and linking. * Some internal refactorings on the link stage of the compiler was done to work directly from `CompiledModule` structures instead of lists of paths. * The trans time-graph output was tweaked a little to include a name on each bar and inflate the size of the bars a little

Manually set dso_local when its valid to do so This should have no real effect in most cases, as e.g. `hidden` visibility already implies `dso_local` (or at least LLVM IR does not preserve the `dso_local` setting if the item is already `hidden`), but it should fix `-Crelocation-model=static` and improve codegen in executables. Note that this PR does not exhaustively port the logic in [clang]. Only the obviously correct portion and what is necessary to fix a regression from LLVM 12 that relates to `-Crelocation_model=static`. Fixes #83335 [clang]: https://github.com/llvm/llvm-project/blob/3001d080c813da20b329303bf8f45451480e5905/clang/lib/CodeGen/CodeGenModule.cpp#L945-L1039

Emit LLVM optimization remarks when enabled with `-Cremark` The default diagnostic handler considers all remarks to be disabled by default unless configured otherwise through LLVM internal flags: `-pass-remarks`, `-pass-remarks-missed`, and `-pass-remarks-analysis`. This behaviour makes `-Cremark` ineffective on its own. Fix this by configuring a custom diagnostic handler that enables optimization remarks based on the value of `-Cremark` option. With `-Cremark=all` enabling all remarks.
