WebAssembly: Stop directly using RuntimeLibcalls.def (#143054) 2025-06-20T00:35:02+00:00 Matt Arsenault Matthew.Arsenault@amd.com 2025-06-20T00:35:02+00:00 efd42b9b1d655a56abb3e6ce1ed4414e9f882912 Construct RuntimeLibcallsInfo instead of manually creating a map. This was repeating the setting of the RETURN_ADDRESS. This removes an obstacle to generating libcall information with tablegen. This is also not great, since it's setting a static map which would be broken if there were ever a triple with a different libcall configuration.

 [aarch64] Fix Arm64EC libcall lowering after recent refactoring. (#143977) 2025-06-16T07:15:06+00:00 Eli Friedman efriedma@quicinc.com 2025-06-16T07:15:06+00:00 222ab28a9240e03479341cba2f487b8350635fce The refactored code accidentally tokenized a string instead of just concatenating it. Add a regression test and some assertions to ensure consistency. Fixes #143890 .

 [CodeGen] Use __extendhfsf2 and __truncsfhf2 by default (#126880) 2025-02-19T09:16:57+00:00 Nikita Popov npopov@redhat.com 2025-02-19T09:16:57+00:00 cc539138acf742f53ef455147182a8de11980a02 The standard libcalls for half to float and float to half conversion are __extendhfsf2 and __truncsfhf2. However, LLVM currently uses __gnu_h2f_ieee and __gnu_f2h_ieee instead. As far as I can tell, these libcalls are an ARM-ism and only provided by libgcc on that platform. compiler-rt always provides both libcalls. Use the standard libcalls by default, and only use the __gnu libcalls on ARM.

## Change:
- WebAssemblyRuntimeLibcallSignatures.cpp: Expose the RTLIB's for use by
WASM
-  Add trig specific test cases

## History
This change is part of an implementation of
https://github.com/llvm/llvm-project/issues/87367's investigation on
supporting IEEE math operations as intrinsics.
Which was discussed in this RFC:
https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294

This change adds wasm lowering cases for `acos`, `asin`, `atan`, `cosh`,
`sinh`, and `tanh`.

## Why Web Assembly?
From past changes to try and support constraint intrinsics the changes
to the trig builtins to emit intrinsics\constraint intrinsics broke the
WASM build. This is an attempt to preempt any such build break.
