Subject: Register the __builtin_va_list_type node when we parse it, rather than
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6309737da76f583f217c393dc8008f193e196975;p=clang

Register the __builtin_va_list_type node when we parse it, rather than
waiting until we think we need it: we didn't catch all of the places
where we actually needed it, and we probably wouldn't ever. Fixes a
C++ PCH crasher.
