[llvm-commits] [llvm-gcc-4.0] r43134 - in /llvm-gcc-4.0/trunk/gcc/config/rs6000: darwin-ldouble.c darwin-libgcc.10.4.ver darwin-libgcc.10.5.ver darwin.h

New Revision: 43134

URL: http://llvm.org/viewvc/llvm-project?rev=43134&view=rev
Log:
Enable 128-bit long double on PPC darwin.
Remove hacks in library functions and build which 
worked around its absence.

This changes the ABI.  Also note that some functions
in libgcc now have a different interface, so make
sure you build and pick up the right ones.
