Subject: avoid a crash when we encounter a implicit cast of the paren expr due to
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c1f3b28004a032f4cd13721d4d884c6dcec29c31;p=clang

avoid a crash when we encounter a implicit cast of the paren expr due to
promotions.  This should be fixed by not modeling asm operands (which
require the ()'s according to the grammar) as not being paren exprs.
