[PATCH] D75300: Support prefix padding for alignment purposes (Relaxable instructions only)

[Kan Shengchen via Phabricator via llvm-commits]

skan added inline comments.


================
Comment at: llvm/lib/Target/X86/MCTargetDesc/X86AsmBackend.cpp:110
+    "x86-pad-max-prefix-size", cl::init(0),
+    cl::desc("Maximum number of redundant prefixes to use for padding"));
+
----------------
Before landing this patch, could you make this description better? I don't think the word "redundant" is appropriate here since `X86PadMaxPrefixSize` counts  in the existing prefixes of the instructions，which may be useful, e.g. escape prefix.
