@ -3,6 +3,18 @@ Pull in r221170 from upstream clang trunk (by Roman Divacky):
|
||||
Implement vaarg lowering for ppc32. Lowering of scalars and
|
||||
aggregates is supported. Complex numbers are not.
|
||||
|
||||
Pull in r221174 from upstream clang trunk (by Roman Divacky):
|
||||
|
||||
Require asserts to unbreak the buildbots.
|

|

Pull in r221284 from upstream clang trunk (by Roman Divacky):
|
||||
|
||||
Rewrite the test to not require asserts.

Pull in r221285 from upstream clang trunk (by Roman Divacky):
|
||||
|
||||
Since the file has both ppc and ppc64 tests in it rename it.
|
||||
|
||||
This adds va_args support for PowerPC (32 bit) to clang.
