With this modification for SPE in VAARG, I was now able to compile all OS-9
libraries for SPE and tested them with whetstone. The results of the whetstone
are the same like with a real FPU and they are correctly shown with printf.
Also the performance of CLANG is about 30% better than with my old compiler.
Therefore, the modification in tools/clang/lib/CodeGen/TargetInfo.cpp line 9322
case llvm::Triple::ppc:
return SetCGInfo(
new PPC32TargetCodeGenInfo(Types, (CodeGenOpts.FloatABI == "soft") ||
getTarget().hasFeature("spe")));
case llvm::Triple::ppc64:
Helps to get the va_arg() parameter correctly. We should not rename the
isSoftFloatABI to something else, because this is just one line of code change
compared to >12 lines. Also the naming is still correct and not really
confusing.
Conclusion: the SPE is now at a level, where it can be used completely.
