Merge pull request #642 from tgross35/android-testing-fix 
Fix missing `extern "C"` on `unsafe` intrinsics
 2024-07-24 12:44:54 +01:00

ddd97dc19a Fix missing extern "C" for unsafe functions 
`unsafe` functions were being matched in a different block that did not
include `extern $abi`. This means that some intrinsics were getting
generated with the Rust ABI rather than C.

Combine the last two blocks using an optional token matcher, which fixes
this problem and is cleaner.

These can be emitted by gcc, at least if requested specifically via __builtin_bswap{32,64,128}.

Since updating the docker images in
<https://github.com/rust-lang/compiler-builtins/pull/625>, it looks like
`__extendhftf2` and `__trunctfhf2` are available on all 64-bit Linux
platforms.

__addkf3 and __mulkf3 seem to hit a nondescript SIGILL. This is probably
likely to just be another Qemu limitation.

Disable libm on x86 without sse2

e35091a2d0 Disable libm on x86 without sse2 
In <https://github.com/rust-lang/compiler-builtins/pull/594>, symbols
for the Rust port of libm were made always weakly available. This seems
to be causing problems on platforms with ABI issues, as explained at
<https://github.com/rust-lang/rust/pull/125016#issuecomment-2174572661>.

Disable Rust libm on x86 without sse2 to mitigate this.

6cd17ff4d2 Add benchmarks for floating point math 
This adds comparisons among the compiler-builtins function, system
functions if available, and optionally handwritten assembly.

These also help us identify inconsistencies between this crate and
system functions, which may otherwise go unnoticed if intrinsics get
lowered to inline operations rather than library calls.

c7bd2a5655 Add ppc_alias to the intrinsics! macro 
PowerPC platforms use `kf` rather than `tf` for `f128`. Add a way to
alias this in the macro to make the code cleaner.

This also fixes the names of `fixunstf*` and `fixtf*` on Power PC
(`fixunskf*` and `fixkf*` are correct).

`as` casts are only allowed for primitives, doing the same operations
with `rustc_apfloat` requires using functions. Add a way to specify
these separately.
