Mikael Holmen 925deed9df Add a emitUnaryFloatFnCall version that fetches the function name from TLI ... Summary: In several places in the code we use the following pattern: if (hasUnaryFloatFn(&TLI, Ty, LibFunc_tan, LibFunc_tanf, LibFunc_tanl)) { [...] Value *Res = emitUnaryFloatFnCall(X, TLI.getName(LibFunc_tan), B, Attrs); [...] } In short, we check if there is a lib-function for a certain type, and then we _always_ fetch the name of the "double" version of the lib function and construct a call to the appropriate function, that we just checked exists, using that "double" name as a basis. This is of course a problem in cases where the target doesn't support the "double" version, but e.g. only the "float" version. In that case TLI.getName(LibFunc_tan) returns "", and emitUnaryFloatFnCall happily appends an "f" to "", and we erroneously end up with a call to a function called "f". To solve this, the above pattern is changed to if (hasUnaryFloatFn(&TLI, Ty, LibFunc_tan, LibFunc_tanf, LibFunc_tanl)) { [...] Value *Res = emitUnaryFloatFnCall(X, &TLI, LibFunc_tan, LibFunc_tanf, LibFunc_tanl, B, Attrs); [...] } I.e instead of first fetching the name of the "double" version and then letting emitUnaryFloatFnCall() add the final "f" or "l", we let emitUnaryFloatFnCall() fetch the right name from TLI.
