Best to state that this currently triggers a report_fatal_error in llvm::MCAsmBackend::relaxInstruction.



================
Comment at: llvm/test/MC/X86/align-branch-64-relax-all.s:2
   # RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu --x86-align-branch-boundary=32 --x86-align-branch=fused+jcc --mc-relax-all %s | llvm-objdump -d --no-show-raw-insn - | FileCheck %s
+  # RUN: llvm-mc -filetype=obj -triple x86_64-pc-linux-gnu --x86-align-branch-boundary=32 --x86-align-branch=fused+jcc --x86-pad-max-prefix-size=5 --mc-relax-all %s | llvm-objdump -d --no-show-raw-insn - | FileCheck %s
 
----------------
You can actually strip `-pc-linux-gnu`. ELF is the default.
