These are two small patches which originally dealt with the problem found at:
https://github.com/ClangBuiltLinux/linux/issues/1364
The original steps to reproduce were: $ make -skj"$(nproc)" LLVM=1 LLVM_IAS=1 defconfig $ scripts/config -e X86_DECODER_SELFTEST $ make -skj"$(nproc)" LLVM=1 LLVM_IAS=1 olddefconfig bzImage
Which resulted in the error: arch/x86/tools/insn_decoder_test: warning: objdump says 0 bytes, but insn_get_length() says 2
Upon inspection it turned out llvm-objdump was formatting its output differently, which caused objdump_reformat.awk to incorrectly output its values.
After fixing that bug, a second one was seen where the instruction "wait" was incorrectly matched with "fwait", which again caused insn_decoder_test to fail.
Samuel Zeter (2): arch/x86/tools/objdump_reformat.awk: Ensure regex matches fwait arch/x86/tools/objdump_reformat.awk: Allow for spaces
