Hi All,

We found out that compiler configured with '-fpmath=sse' option does
not generate scalar floating-point instructions present in the SSE
instruction set for generic32 that leads to performance degradation
for Fortran benchmarks using library functions in 32-bit mode.

This simple fix was designed to cure this issue - definition of
TARGET_FPMATH_DEFAULT_P macros was missed in i386/ssemath.h. Also one
missed fix was done.

Bootstrapping and regression testing were successful.

Is it OK for trunk

2013-11-20  Yuri Rumyantsev  <ysrumyan@gmail.com>

* config/i386/i386.c (ix86_option_override_internal): Add missed
argument prefix for 'ix86_fpmath'.
* config/i386/ssemath.h: Add missed definition of
TARGET_FPMATH_DEFAULT_P macros.
