Szabolcs Nagy	7ee48f7b69	fix fesetenv(FE_DFL_ENV) on x86_64 (see previous commit)	12 years ago
Szabolcs Nagy	a6b0170a7f	fix fenv exception functions to mask their argument fesetround.c is a wrapper to do the arch independent argument check (on archs where rounding mode is not stored in 2 bits __fesetround still has to check its arguments) on powerpc fe*except functions do not accept the extra invalid flags of its fpscr register the useless FENV_ACCESS pragma was removed from feupdateenv	13 years ago
Szabolcs Nagy	d8764bf840	optimize x86 feclearexcept: only use save/restore x87 fenv if needed the x87 exception summary (ES) and stack fault (SF) flags may be spuriously cleared by feclearexcept using the fnclex instruction, but these flags are not observable through libc hence maintaining their state is not critical.	13 years ago
Szabolcs Nagy	ebc10fa176	add sse fenv support on i386 through hwcap the sse and x87 rounding modes should be always the same, the visible exception flags are the bitwise or of the two fenv states (so it's enough to query the rounding mode or raise exceptions on one fenv)	13 years ago
Rich Felker	b60053e762	try fixing/optimizing x86_64 fenv exception code untested; may need followup-fixes.	14 years ago
Rich Felker	9cb6878e74	fix x86_64 fe[gs]etround, analogous to nsz's x86 changes	14 years ago
Rich Felker	e411827960	use type directives for fenv asm functions	15 years ago
Rich Felker	773b0fe447	x86_64 fenv support (untested; at least known to build successfully)	15 years ago
