Subject: Fix parsing of initializer lists with elaborated type specifier.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=606e07ecc0b7b0e01d23baa833b4b4c73af0d4f4;p=clang

Fix parsing of initializer lists with elaborated type specifier.

Now we correctly parse and format:
verifyFormat("struct foo a = { bar };
int n;
