- Subject: [patch] for gcc/testsuite/gcc.dg/builtin-apply4.c failure on x86 Mac OS
We, at Apple, found gcc/testsuite/gcc.dg/builtin-apply4.c failed on
x86 Mac OS.
The regression was caused by a fsf ABI change. We must maintain binary
compatibility on our platforms.
The following patch has been tested on x86 MacOS with "make all", "--
enable-languages=c,c++,objc,obj-c++", and regression tested with a top-
level "make check-gcc" with no regression.
gcc/ChangeLog:
* config/i386/i386.c (ix86_function_arg_regno_p,
ix86_function_value_regno_p) : Put back the code before
the following patch under TARGET_MACHO.

* config/i386/i386.c (ix86_function_arg_regno_p): Add
MMX_REGNO_P
for TARGET_MMX. Use MMX_REGPARM_MAX and SSE_REGPARM_MAX for
MMX
and SSE registers to determine if regno is valid.
(ix86_function_value_regno_p): Depend FIRST_FLOAT_REG on
TARGET_FLOAT_RETURNS_IN_80387 also for TARGET_64BIT. Clean up.
