2024-07-11 | selftests/x86: build sysret_rip.c with clang | John Hubbard | |
When building with clang, via: make LLVM=1 -C tools/testing/selftests ...the build fails because clang's inline asm doesn't support all of the features that are used in the asm() snippet in sysret_rip.c. Fix this by moving the asm code into the clang_helpers_64.S file, where it can be built with the assembler's full set of features.

2024-07-11 | selftests/x86: build fsgsbase_restore.c with clang | John Hubbard | |
When building with clang, via: make LLVM=1 -C tools/testing/selftests Fix this by moving the inline asm to "pure" assembly, in two new files: clang_helpers_32.S, clang_helpers_64.S. As a bonus, the pure asm avoids the need for ifdefs, and is now very simple and easy on the eyes.
