Daniel Eischen	5f864214bb	Use C comments since we now preprocess these files with CPP.	2007-04-29 14:05:22 +00:00
Daniel Eischen	d7eda46253	Add symbol versioning to libm.	2006-03-27 23:59:45 +00:00
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
Olivier Houchard	15d3b4db61	Define FE_TONEAREST, FE_TOWARDZERO, FE_UPWARD, FE_DOWNWARD and _ROUND_MASK to ... unbreak the build for arm.	2005-01-24 00:35:02 +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
Olivier Houchard	60b22cf1c2	Only use rfs and wfs if ARM_HARD_FLOAT is defined, and use stubs if it is not, ... in order to unbreak arm make world. The right way to do it with soft floats will be figured out later. Discussed with: das	2004-08-05 14:07:24 +00:00
David Schultz	19220bc13f	Add an fenv.h implementation for the arm port. ... It does not appear to be possible to cross-build arm from i386 at the moment, and I have no ARM hardware anyway. Thus, I'm sure there are bugs. I will gladly fix these when the arm port is more mature. Reviewed by: standards@	2004-06-06 10:03:59 +00:00
