URL: http://llvm.org/viewvc/llvm-project?rev=348033&view=rev
Log:
Adding tests for -ast-dump; NFC.
This adds tests for struct and union declarations in C. It also points out a bug when dumping anonymous record types -- they are sometimes reported as being contained by something of the wrong tag type. e.g., an anonymous struct inside of a union named X reports the anonymous struct as being inside of 'struct X' rather than 'union X'.
