Hello Emscripten devs!
I'm trying to compile an LLVM IR file to JS using emscripten. Some functions in that file use the Sin function and it's declared as follows:
declare double @llvm.sin.f64(double) #2
; Other code ...
attributes #2 = { nounwind readnone }
When I compile my LLVM IR file, emcc
complains about a missing sin function:
warning: unresolved symbol: llvm_sin_f64
I noticed that the dots are replaced with underscores in the function name, but my files doesn't contain any references to that function; only to the standard LLVM one with dots.
Since emcc
can't find this function it has an incomplete implementation in the generated JS:
function _llvm_sin_f64() {
Module['printErr']('missing function: llvm_sin_f64'); abort(-1);
}
I'm running the 64 bit version of emscripten from the incoming
branch.
Is the @llvm.sin.f64
intrinsic unsupported? Or is this a bug?
