Dan Gohman	e665e781dc	[SelectionDAG] Use the nuw flag when expanding loads. (#119288) ... When expanding a load into two loads, use nuw for the add that computes the offset from the base of the second load, because the original load doesn't straddle the address space. It turns out there's already a dedicated helper function for doing this, `getObjectPtrOffset`. This is in target-independent code, however in practice it only seems to affact WebAssembly code, because WebAssembly load and store instructions' constant offsets don't perform wrapping, so constant folding often depends on the nuw flag being present. This was noticed in the development of #119204.	2024-12-10 06:28:09 -08:00
Tex Riddell	2bebeea2a1	[WebAssembly] Add atan2 to RuntimeLibcallSignatureTable (#112613) ... This change is part of this proposal: https://discourse.llvm.org/t/rfc-all-the-math-intrinsics/78294 - `WebAssemblyRuntimeLibcallSignatures.cpp`: Add `RTLIB::ATAN2*` to RuntimeLibcallSignatureTable - Add atan2 calls to `CodeGen/WebAssembly/libcalls-trig.ll` and update test checks Part of: Implement the atan2 HLSL Function #70096.	2024-10-17 10:39:36 -07:00
Farzon Lotfi	def3944df8	[WebAssembly] Add Support for Arc and Hyperbolic trig llvm intrinsics (#98755) ... ## 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`. https://github.com/llvm/llvm-project/issues/70079 https://github.com/llvm/llvm-project/issues/70080 https://github.com/llvm/llvm-project/issues/70081 https://github.com/llvm/llvm-project/issues/70083 https://github.com/llvm/llvm-project/issues/70084 https://github.com/llvm/llvm-project/issues/95966 ## 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. - https://github.com/llvm/llvm-project/pull/95082 - https://github.com/llvm/llvm-project/pull/94559#issuecomment-2159923215	2024-07-19 10:18:58 -04:00
