Subject: [ARM] Mark labels in skipAlignedDPRCS2Spills as fallthrough (NFC).
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=621b075f66e44c87f26c8936784f4c29d4fe42df;p=llvm

[ARM] Mark labels in skipAlignedDPRCS2Spills as fallthrough (NFC).

The comment at the top of the switch statement indicates that the
fall-through behavior is intentional. By using LLVM_FALLTHROUGH,
-Wimplicit-fallthrough are silenced, which is enabled by default in GCC
7.
