...ions defined in TargetInfo. The TargetInfo member functions are called multiple times for each relocation. So the cost of virtual function calls may be non-neglible. That is a motication to do the following test. As a test, I removed all TargetInfo subclasses except for x86-64, move all code from X86_64TargetInfo to TargetInfo, and remove `virtual` from TargetInfo. The original LLD links itself (with debug info) in 7.499 seconds. The de-virtualized version did the same thing in 7.364 seconds. So it can improve it by 1.8%. I'm just pointing out that there's room there to improve performance, and I&...

...9;   1 error generated. The target selection is a little tricky here and I wonder if it's on purpose or not. One solution is to add another line:   TT.setOS(llvm::Triple::UnknownOS); This line removes the OS info from my triple, so that the AllocateTarget() function no longer returns a DarwinX86_64TargetInfo from here: https://github.com/llvm-mirror/clang/blob/71928e1dab585f336f6d0fb337969eda00ccd19c/lib/Basic/Targets.cpp#L491 The problem with DarwinX86_64TargetInfo is, that it's hard-coded for Mach-O. It always sets the same data-layout string in the target description: https://github.com/llvm-mi...

Hi, I'm working on bringing up complete coverage for a Gentoo x32 "desktop" system. I've been cooking up quite a few patches for various packages to push upstream, but right now, the biggest blocker is the lack of support for building with/codegen targeting x32 in llvm/clang. Since the x32 patches were sent last year, I see support code has landed in LLVM, and basic handling of
