Rafal Jaworowski	56ae1bed48	Let PowerPC world optionally build with -msoft-float. For FPU-less PowerPC ... variations (e500 currently), this provides a gcc-level FPU emulation and is an alternative approach to the recently introduced kernel-level emulation (FPU_EMU).

David Schultz	10b01832c3	Replace fegetmask() and fesetmask() with feenableexcept(), ... fedisableexcept(), and fegetexcept(). These two sets of routines provide the same functionality. I implemented the former as an undocumented internal interface to make the regression test easier to write. However, fe(enable|disable|get)except() is already part of glibc, and I would like to avoid gratuitous differences. The only major flaw in the glibc API is that there's no good way to report errors on processors that don't support all the unmasked exceptions.	2005-03-16 19:03:46 +00:00
David Schultz	4be31f0664	Define the LDBL_PREC to be the number of significant bits in a long ... double's mantissa.	2005-03-07 04:53:36 +00:00
David Schultz	f365db00e5	Mark all inline asms that read the floating-point control or status ... registers as volatile. Instructions that *wrote* to FP state were already marked volatile, but apparently gcc has license to move non-volatile asms past volatile asms. This broke amd64's feupdateenv at -O2 due to a WAR conflict between fnstsw and fldenv there.	2005-01-14 07:09:23 +00:00
