Description Andrew Aladjev 2020-02-25 15:24:53 UTC

Please see the following files:

1. https://github.com/llvm/llvm-project/blob/master/compiler-rt/lib/builtins/CMakeLists.txt#L371
2. https://github.com/llvm/llvm-project/blob/master/compiler-rt/lib/builtins/arm/aeabi_cdcmp.S#L11-L13

Today "compiler-rt" component from "llvm" is not implemented for "armeb". I've received the following error while trying to build "sys-libs/compiler-rt" for "armeb-unknown-linux-gnueabi":

/var/tmp/portage/sys-libs/compiler-rt-9.0.1/work/compiler-rt/lib/builtins/arm/aeabi_cfcmp.S:12:2:
error: big endian support not implemented

I've found no way to disable assembler and use some c code instead. So please mask "sys-libs/compiler-rt" and "sys-libs/compiler-rt-sanitizers" for "armeb". It will force armeb users to disable "sanitize" use for "clang".


Reproducible: Always
