Subject: [Local] Update the comment for removeUnreachableBlocks.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5c0bc9394d1d561951bdd65d7d95dae494ac576c;p=llvm

[Local] Update the comment for removeUnreachableBlocks.

It referenced a wrong function name, and didn't mention what the
second argument did. This should be slightly more accurate now.
