[PATCH] libffi fixes for m68k
- From: Andreas Schwab <schwab at linux-m68k dot org>
- To: gcc-patches at gcc dot gnu dot org
- Date: Sat, 14 Jan 2012 21:42:02 +0100
- Subject: [PATCH] libffi fixes for m68k
The only way to detect compiling for a plain 68000 is the absense of
other defines since __mc68000__ is always defined. Also, gcc defines
__HAVE_68881__, not __MC68881__. The latter fixes failures of all tests
involving floating point return values. Tested on m68k-linux.
Andreas.

* src/m68k/sysv.S (ffi_call_SYSV): Properly test for plain
mc68000. Test for __HAVE_68881__ in addition to __MC68881__.
