9ac175c503 rustc: Use static strings in a few literals
Avoid allocating extra copies of strings by using "" instead of ~"" for
the debug options list and for the `time` function. This is a small
change, but it is in a path that's always executed.

c9d4ad07c4 remove the float type
It is simply defined as `f64` across every platform right now.

A use case hasn't been presented for a `float` type defined as the
highest precision floating point type implemented in hardware on the
platform. Performance-wise, using the smallest precision correct for the
use case greatly saves on cache space and allows for fitting more
numbers into SSE/AVX registers.

If there was a use case, this could be implemented as simply a type
alias or a struct thanks to `#[cfg(...)]`.

Closes #6592

This also prevents future fmt! usage from leaking into the compiler, but it's still turned on by default for everyone else.

350b5438cd add -Z soft-float option
This change adds -Z soft-float option for generating
software floating point library calls.
It also implies using soft float ABI, that is the same as llc.

It is useful for targets that have no FPU.

c3e4e06841 remove type_use
This is broken, and results in poor performance due to the undefined
behaviour in the LLVM IR. LLVM's `mergefunc` is a *much* better way of
doing this since it merges based on the equality of the bytecode.

For example, consider `std::repr`. It generates different code per
type, but is not included in the type bounds of generics.

The `mergefunc` pass works for most of our code but currently hits an
assert on libstd. It is receiving attention upstream so it will be
ready soon, but I don't think removing this broken code should wait any
longer. I've opened #9536 about enabling it by default.

10a583ce1a Correctly encode item visibility in metadata
This fixes private statics and functions from being usable cross-crates, along
with some bad privacy error messages. This is a reopening of #8365 with all the
privacy checks in privacy.rs instead of resolve.rs (where they should be
anyway).

These maps of exported items will hopefully get used for generating
documentation by rustdoc

8d12673c82 Tweak pass management and add some more options
The only changes to the default passes is that O1 now doesn't run the inline
pass, just always-inline with lifetime intrinsics. O2 also now has a threshold
of 225 instead of 275. Otherwise the default passes being run is the same.

I've also added a few more options for configuring the pass pipeline. Namely you
can now specify arguments to LLVM directly via the `--llvm-args` command line
option which operates similarly to `--passes`. I also added the ability to turn
off pre-population of the pass manager in case you want to run *only* your own
passes.

73540551e5 Rewrite pass management with LLVM
Beforehand, it was unclear whether rust was performing the "recommended set" of
optimizations provided by LLVM for code. This commit changes the way we run
passes to closely mirror that of clang, which in theory does it correctly. The
notable changes include:

* Passes are no longer explicitly added one by one. This would be difficult to
  keep up with as LLVM changes and we don't guaranteed always know the best
  order in which to run passes
* Passes are now managed by LLVM's PassManagerBuilder object. This is then used
  to populate the various pass managers run.
* We now run both a FunctionPassManager and a module-wide PassManager. This is
  what clang does, and I presume that we *may* see a speed boost from the
  module-wide passes just having to do less work. I have no measured this.
* The codegen pass manager has been extracted to its own separate pass manager
  to not get mixed up with the other passes
* All pass managers now include passes for target-specific data layout and
  analysis passes

Some new features include:

* You can now print all passes being run with `-Z print-llvm-passes`
* When specifying passes via `--passes`, the passes are now appended to the
  default list of passes instead of overwriting them.
* The output of `--passes list` is now generated by LLVM instead of maintaining
  a list of passes ourselves
* Loop vectorization is turned on by default as an optimization pass and can be
  disabled with `-Z no-vectorize-loops`

6928a10e3f auto merge of #8362 : sfackler/rust/env, r=alexcrichton
env! aborts compilation of the specified environment variable is not
defined and takes an optional second argument containing a custom
error message. option_env! creates an Option<&'static str> containing
the value of the environment variable.

There are no run-pass tests that check the behavior when the environment
variable is defined since the test framework doesn't support setting
environment variables at compile time as opposed to runtime. However,
both env! and option_env! are used inside of rustc itself, which should
act as a sufficient test.

Fixes #2248.

a931e04b75 auto merge of #8350 : dim-an/rust/fix-struct-match, r=pcwalton
Code that collects fields in struct-like patterns used to ignore
wildcard patterns like `Foo{_}`. But `enter_defaults` considered
struct-like patterns as default in order to overcome this
(accoring to my understanding of situation).

However such behaviour caused code like this:
```
enum E {
    Foo{f: int},
    Bar
}
let e = Bar;
match e {
    Foo{f: _f} => { /* do something (1) */ }
    _ => { /* do something (2) */ }
}
```
consider pattern `Foo{f: _f}` as default. That caused inproper behaviour
and even segfaults while trying to destruct `Bar` as `Foo{f: _f}`.
Issues: #5625 , #5530.

This patch fixes `collect_record_or_struct_fields` to split cases of
single wildcard struct-like pattern and no struct-like pattern at all.
Former case resolved with `enter_rec_or_struct` (and not with
`enter_defaults`).

Closes #5625.
Closes #5530.
