Subject: When generating the CodeGen type name of a struct, union, enum use the typedef
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0f8db7021ef6a9f16f2571ecf68cc3f3eda4eae5;p=clang

When generating the CodeGen type name of a struct, union, enum use the typedef
name if a tag type name is not available for the type. This matches how llvm-gcc
chooses CodeGen type names.

This means that "typedef struct {...} foo" now results in a CodeGen name of
"struct.foo" rather than "struct."
