Diff to add ARMv6L to Target parser
...I’ve been working with Swift on ARMv6 and v7. While working with ARMv6 on linux, I noticed that my arm architecture canonicalization code didn’t produce the expected result. The code that I had been using (within Swift’s Driver.cpp the following:
static llvm::Triple computeTargetTriple(StringRef DefaultTargetTriple) {
llvm::Triple triple = llvm::Triple(DefaultTargetTriple);
// Canonicalization of all armv6 sub architectures to armv6
if (triple.getArch() == llvm::Triple::ArchType::arm) {
if (triple.getSubArch() == llvm::Triple::SubArchType::ARMSubArch_v6 ||
triple.getSubArch() == llvm::Tri...

Diff to add ARMv6L to Target parser
...ess, I'll leave you guys to review this one, as I lost touch with the parser a while ago.
Ah, I see: ARMv7L is now an alias for ARMv7A.
So, if William has to add support for ARMv6L, I'd suggest he adds it as an alias, and not as an architecture variant.
>>> However, because the DefaultTargetTriple is armv6l-unknown-linux-gnueabihf
Where is this "armv6l" coming from? Is it a legacy GNU thing? Or is it a newly-coined name?

[LLVMdev] [RFC PATCH] X32 ABI support for Clang/compiler-rt
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
