I removed the `static-method-test.rs` test because it was heavily based
on `BaseIter` and there are plenty of other more complex uses of static
methods anyway.
This is another big refactoring of `trans` though this is unlikely to have much of an
impact on code size or speed.
The major change here is the implementation of a `Type` struct which is the new
home for all your LLVM `TypeRef` needs. It's a simple wrapper struct, with static
methods for constructing types, then regular methods for
manipulating/interrogating them. The purpose of this is mostly to make the code
surrounding them somewhat more ideomatic. A line like: `T_ptr(T_ptr(T_i8()))` is
now `Type::i8().ptr_to().ptr_to()`,which is much more like regular Rust code.
There are a variety of smaller changes here and there:
* Remove address spaces. At least it doesn't generate them, I haven't spent much
time looking for related code.
* Use a macro for declaring the LLVM intrinsics, makes it look much nicer.
* Make the type for a string slice actually create a named `str_slice` type in LLVM,
this makes reading the appropriate code much easier.
* Change the way struct and enum type names are generated. This just means
that a struct like `struct Foo { a: int }` now produces the IR
`%struct.Foo = type { i64 }`, which is much easier to read. Similarly, other structs
are a bit tighter to make it easier to read.

This PR did get away from me a little, as I occasionally got distracted or as I fixed
up problems with unrelated code that were stopping me from continuing. One major
thing is that this PR contains the work from #7168, since that would have conflicted
with this and it was broken anyway. Sorry for bundling it like this.
Fixes#3670 and #7063

EDIT: This no longer removes the llvm insn stats.
This is a bad default, because the binaries will point at an absolute
path regardless of where they are moved. This opens up a security issue
for packages, because they will attempt to load libraries from a path
that's often owned by a regular user.
Every Rust binary is currently flagged by Debian, Fedora and Arch lint
checkers as having dangerous rpaths. They don't meet the requirements to
be placed in the repositories without manually stripping this from each
binary.
The relative rpath is still enough to keep the binaries working until
they are moved relative to the crates they're linked against.

Remove all the explicit @mut-fields from CrateContext, though many
fields are still @-ptrs.
This required changing every single function call that explicitly
took a @CrateContext, so I took advantage and changed as many as I
could get away with to &-ptrs or &mut ptrs.
This un-reverts the reverts of the rusti commits made awhile back. These were reverted for an LLVM failure in rustpkg. I believe that this is not a problem with these commits, but rather that rustc is being used in parallel for rustpkg tests (in-process). This is not working yet (almost! see #7011), so I serialized all the tests to run one after another.
@brson, I'm mainly just guessing as to the cause of the LLVM failures in rustpkg tests. I'm confident that running tests in parallel is more likely to be the problem than those commits I made.
Additionally, this fixes two recently reported issues with rusti.
This almost removes the StringRef wrapper, since all strings are
Equiv-alent now. Removes a lot of `/* bad */ copy *`'s, and converts
several things to be &'static str (the lint table and the intrinsics
table).
There are many instances of .to_managed(), unfortunately.
Handle more characters that appear in types, most notably <>): were
missing. Also the new scheme takes care that no two different input
strings result in the same mangled string, which was not the case before.
Fixes#6921

Fix a laundry list of warnings involving unused imports that glutted
up compilation output. There are more, but there seems to be some
false positives (where 'remedy' appears to break the build), but this
particular set of fixes seems safe.

This refactors pass handling to use the argument names, so it can be used
in a similar manner to `opt`. This may be slightly less efficient than the
previous version, but it is much easier to maintain.
It also adds in the ability to specify a custom pipeline on the command
line, this overrides the normal passes, however. This should completely
close#2396.
Refactor the optimization passes to explicitly use the passes. This commit
just re-implements the same passes as were already being run.
It also adds an option (behind `-Z`) to run the LLVM lint pass on the
unoptimized IR.
mentioned in #2625.
This change makes the module more oriented around
Process values instead of having to deal with process ids
directly.
Apart from issues mentioned in #2625, other changes include:
- Changing the naming to be more consistent - Process/process
is now used instead of a mixture of Program/program and
Process/process.
- More docs/tests.
Some io/scheduler related issues remain (mentioned in #2625).
It uses the private field of TCB head to store stack limit. I tested on my Raspberry PI. A simple hello world program ran without any problem. However, for a more complex program, it segfaulted as #6231.
fail!() used to require owned strings but can handle static strings
now. Also, it can pass its arguments to fmt!() on its own, no need for
the caller to call fmt!() itself.
Fixes#6378
Don't pass the binary name to the LLVMRustExecuteJIT closure, otherwise it will leak memory; the binary name doesn't seem to be needed, anyhow.
&str can be turned into @~str on demand, using to_owned(), so for
strings, we can create a specialized interner that accepts &str for
intern() and find() but stores and returns @~str.
In rustpkg, pass around sysroot; in rustpkg tests, set the sysroot
manually so that tests can find libcore and such.
With bonus metadata::filesearch refactoring to avoid copies.
I don't know how one would write a separate test for this sort of thing. Building the compiler, and `make check` worked, which should mean I didn't screw anything.
I've added trt_field_vtable, trt_field_box, and trt_field_tydesc, and
inserted them in place of the "magic numbers" used to access trait
object fields through GEPi().
I believe this patch incorporates all expected syntax changes from extern
function reform (#3678). You can now write things like:
extern "<abi>" fn foo(s: S) -> T { ... }
extern "<abi>" mod { ... }
extern "<abi>" fn(S) -> T
The ABI for foreign functions is taken from this syntax (rather than from an
annotation). We support the full ABI specification I described on the mailing
list. The correct ABI is chosen based on the target architecture.
Calls by pointer to C functions are not yet supported, and the Rust type of
crust fns is still *u8.
Removes a lot of instances of `/*bad*/ copy` throughout libsyntax/librustc. On the plus side, this shaves about 2s off of the runtime when compiling `librustc` with optimizations.
Ideally I would have run a profiler to figure out which copies are the most critical to remove, but in reality there was a liberal amount of `git grep`s along with some spot checking and removing the easy ones.
Partial Fix for #5265
- Enabling LLVM ARM ehabi option.
- Add ARM debug information manually for ccall.s
- Compile object file using Android-NDK.
Current LLVM trunk version can generate ARM debug information for assembly files but it is incomplete for object files. Unwinding on ARM can be done with LLVM trunk(the LLVM submodule of rust has problem on generating ARM debug information). See #5368
The Android-NDK detour(0f89eab) can be removed after LLVM has complete feature of generating ARM debug information for object file.

This removes `log` from the language. Because we can't quite implement it as a syntax extension (probably need globals at the least) it simply renames the keyword to `__log` and hides it behind macros.
After this the only way to log is with `debug!`, `info!`, etc. I figure that if there is demand for `log!` we can add it back later.
I am not sure that we ever agreed on this course of action, though I *think* there is consensus that `log` shouldn't be a statement.
Issue #3869
review? @nikomatsakis
Convert all uses of vec::slice to vec::view Issue #3869
Rename const_view to const_slice
Renamed mut_view to mut_slice
Fix windows build error. `buf` is borrowed by the call to
`as_mut_buf()` and so we must invoke `slice()` outside of that
call.
