Subject: Extend ASTContext::getTypeInfo() and ASTContext::getObjCEncodingForType() for BlockTypes.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=485eeff9ba73376c8e01179bf1a501b1723446cb;p=clang

Extend ASTContext::getTypeInfo() and ASTContext::getObjCEncodingForType() for BlockTypes.

This fixes <rdar://problem/6240616> clang: Assertion failed when using typedef and Blocks.
