...TargetJumpTable<0> [ID=3] In function: __atomic_compare_exchange clang: error: clang frontend command failed with exit code 70 (use -v to see invocation) clang version 3.4 (trunk) Target: x86_64-pc-linux-gnux32 Thread model: posix This is what happens when compiling compiler-rt with -m64 or -mx32, exact same error without my patches (where -mx32 is supported). However, I know -mx32 isn't working since the objects always end up elf_x86_64, which is why I known this is a somewhat unrelated bug.

Ah, I've replied in a different thread already. What Dmitri says - If you're interesting in only building the Clang on x32 host, you may avoid checking out compiler-rt repo for now.

...stream, 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 32-bit pointers in Clang, but no elf32_x86_64 codegen or support for the -mx32 switch. I've been trying to get x32 ABI support working in Clang and compiler-rt, I based off the previous clang patch, bringing it up to date with the changes in trunk, and hacked together handling of x32 "ARCH" support for compiler-rt. (there must be a better way??) Unfortunately,...

Hi, There's several, to my eyes, somewhat related looking bugs: Bug 36743 - Cannot select: X86ISD::CALL ICE with -mx32 -O2 -fno-plt https://bugs.llvm.org/show_bug.cgi?id=36743 Bug 34268 - JITting of x32 code on x64 fails with crash or instruction selection error. https://bugs.llvm.org/show_bug.cgi?id=34268 There's unfortunately been no investigation. I'm asking because I hit something eerily looking like...

...adding X32 psABI support (https://sites.google.com/site/x32abi/), respectively to LLVM and clang. The patch to LLVM adds X32 psABI support and introduce a new 'X32' environment for x86-64 target to tell X32 psABI from LP64 psABI (i.e. the original x86-64 ABI). The patch to clang adds '-mx32' option to generate x32 binaries as well as support calling convention changes due to pointer size reduction. Please commit the patch if it seems acceptable. This new osABI, X32 psABI, allows programs to run in the 64-bit mode but only using 32-bit pointers. Though, programs will be limited to...
