New Revision: 310057
URL: http://llvm.org/viewvc/llvm-project?rev=310057&view=rev
Log:
Revert r304953 for release 5.0.0
This is causing failures when compiling clang with -O3
as one of the structures used by clang is passed by
value and uses the fastcc calling convention.
Faliures manifest for stage2 mips build.
