[PATCH] D79978: Call Frame Information (CFI) Handling for Basic Block Sections

[Sriraman Tallam via Phabricator via llvm-commits]

tmsriram updated this revision to Diff 277216.
tmsriram added a comment.

Enhance test cfi-basic-block-sections-1.ll to also check for frame-pointer=none.

There is exactly 2 ways in which CFA can be computed:

1. With frame pointer via %ebp
2. Without, where %esp offset is used when frame pointer is omitted

The first test now explicitly checks both to clear any ambiguity here.
