[PATCH] SPU single precision floating point macros and functions
- From: Patrick Mansfield <patmans at us dot ibm dot com>
- To: newlib at sourceware dot org, Jeff Johnston <jjohnstn at redhat dot com>
- Date: Wed, 25 Apr 2007 16:27:03 -0700
- Subject: [PATCH] SPU single precision floating point macros and functions
OK ... re-post, changes since last post: Override __fpclassifyf via the
file sf_fpclassify.c, and add license text to new files.
The SPU/cell single precision floating point does not support NANs or
infinities, and is documented as such. Supply SPU specific macros and
functions for various single precision floating point nan, isfin, isfinite
and fpclassify.
Add and use new macros with __ieeefp_ prefix as well as C99 macros in the
machine/ieeefp.h, keeping the same default values but adding spu specific
ones.
newlib ChangeLog:
2007-04-25 Patrick Mansfield <patmans@us.ibm.com>
* libc/include/ieeefp.h: use prefixed __ieeefp_ macros that can be
overridden via machine/ieeefp.h.
* libc/include/machine/ieeefp.h: Add SPU specific C99 and ieeefp
macros for isnan and related macros.
* libc/include/math.h: Allow C99 isfinite, isinf, and isnan to be
overridden via machine/ieeefp.h.
* libm/machine/spu/Makefile.am: Add new files.
* libm/machine/spu/Makefile.in: Autogenerate with new files.
* libm/machine/spu/sf_fpclassify.c: Add SPU specific __fpclassifyf.
* libm/machine/spu/sf_finite.c: Add SPU specific finitef.
* libm/machine/spu/sf_isinf.c: Add SPU specific isinff.
* libm/machine/spu/sf_isinff.c: Add SPU specific __isinff.
* libm/machine/spu/sf_isnan.c: Add SPU specific isnanf.
* libm/machine/spu/sf_isnanf.c: Add SPU specific __isnanf.
* libm/machine/spu/sf_nan.c: Add SPU specific nanf.
