[PATCH] D94542: [X86] Default to -x86-pad-for-align=false to drop assembler difference with or w/o -g

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

When -mbranches-within-32B-boundaries (to mitigate microcode update for Intel JCC Erratum) is used, there are many alignment fragments. I think D75203 <https://reviews.llvm.org/D75203> has advantage in that case.
In the absence of -mbranches-within-32B-boundaries, I don't think there is demonstrable improvement. I think the assembler relaxation does not pull its weight.
I'll wait another two days.
