Subject: Move the piece of code up that skips the padding argument. Without this change,
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4ba3fd45bb134e4a5119f297537adce4e7ef4a39;p=clang

Move the piece of code up that skips the padding argument. Without this change,
padding insertion will not work if the coerced type is not a structure.
