Closed folkertdev closed 3 months ago

folkertdev commented 3 months ago

part of https://github.com/rust-lang/rustc_codegen_cranelift/issues/1492, but some further intrinsics are needed for the tiny_skia test suite to pass with cranelift:

warning: unsupported x86 llvm intrinsic llvm.x86.sse.rcp.ps; replacing with trap

warning: unsupported x86 llvm intrinsic llvm.x86.sse.rsqrt.ps; replacing with trap

warning: unsupported x86 llvm intrinsic llvm.x86.sse2.psll.d; replacing with trap

warning: unsupported x86 llvm intrinsic llvm.x86.sse2.psrl.d; replacing with trap

nonetheless, this addition makes 26 more tests pass

Thanks!

I'm currently trying to completely rework the way vendor intrinsics are implemented. I don't know if it will work out yet, but maybe hold off on implementing other intrinsics for now.
