Rich Felker	d3fc724759	one more fenv availability issue: lround	14 years ago
Rich Felker	2e77dc13f8	make fma and lrint functions build without full fenv support this is necessary to support archs where fenv is incomplete or unavailable (presently arm). fma, fmal, and the lrint family should work perfectly fine with this change; fmaf is slightly broken with respect to rounding as it depends on non-default rounding modes to do its work.	14 years ago
Rich Felker	8c071f872b	other side of the signgam namespace fix: use the internal name	14 years ago
Rich Felker	1a3dce4184	make signgam a weak alias for an internal symbol otherwise, the standard C lgamma function will clobber a symbol in the namespace reserved for the application.	14 years ago
Rich Felker	de7db6e927	fix namespace issues for lgamma, etc. standard functions cannot depend on nonstandard symbols	14 years ago
Rich Felker	93a50a26cd	Merge remote branch 'nsz/master'	14 years ago
Rich Felker	2cbb24bba3	remove junk sincos implementations in preparation to merge nsz's real ones	14 years ago
Rich Felker	a43c3a337f	revert COPYRIGHT file changes in preparation to merge nsz's math branch	14 years ago
Rich Felker	6f21da618f	update copyright status (math library and new year)	14 years ago
Rich Felker	9d507419db	remove special nan handling from x86 sqrt asm a double precision nan, when converted to extended (80-bit) precision, will never end in 0x400, since the corresponding bits do not exist in the original double precision value. thus there's no need to waste time and code size on this check.	14 years ago
Rich Felker	1295848efb	simplify nan check in sqrt (x86 asm); result of sqrt is never negative	14 years ago
nsz	40305f74bd	in math.h make lgamma_r and non-double bessel _GNU_SOURCE only long double and float bessel functions are no longer xsi extensions	14 years ago
nsz	0144b45b71	efficient sincos based on sin and cos	14 years ago
Rich Felker	5657cc58e5	implement sincosf and sincosl functions; add prototypes presumably broken gcc may generate calls to these, and it's said that ffmpeg makes use of sincosf.	14 years ago
Rich Felker	46702f68f9	avoid changing NaNs in sqrt (x86 asm) to satisfy c99 f.9 recommendation	14 years ago
Rich Felker	809556e60a	correctly rounded sqrt() asm for x86 (i387) the fsqrt opcode is correctly rounded, but only in the fpu's selected precision mode, which is 80-bit extended precision. to get a correctly rounded double precision output, we check for the only corner cases where two-step rounding could give different results than one-step (extended-precision mantissa ending in 0x400) and adjust the mantissa slightly in the opposite direction of the rounding which the fpu already did (reported in the c1 flag of the fpu status word). this should have near-zero cost in the non-corner cases and at worst very low cost. note that in order for sqrt() to get used when compiling with gcc, the broken, non-conformant builtin sqrt must be disabled.	14 years ago
Rich Felker	e0a54e6725	correct rounding for i387 sqrtf function	14 years ago
nsz	32ca5ef3ff	math cleanup: use 1.0f instead of 1.0F	14 years ago
nsz	8d0a6f7a1c	math cleanup: use 1.0f instead of (float)1.0	14 years ago
nsz	9560b6b152	remove libm.h includes when math.h and float.h are enough	14 years ago
Rich Felker	291f839a44	fix scanf handling of "0" (followed by immediate EOF) with "%x" other cases with %x were probably broken too. I would actually like to go ahead and replace this code in scanf with calls to the new __intparse framework, but for now this calls for a quick and unobtrusive fix without the risk of breaking other things.	14 years ago
nsz	df8b3e5aef	clean up __expo2.c, use a slightly better k constant	14 years ago
nsz	3a6c828652	fix copyright notice for the math lib	14 years ago
Rich Felker	bf9d9dcaa6	implement nan, nanf, nanl	14 years ago
Rich Felker	b69f695ace	first commit of the new libm! thanks to the hard work of Szabolcs Nagy (nsz), identifying the best (from correctness and license standpoint) implementations from freebsd and openbsd and cleaning them up! musl should now fully support c99 float and long double math functions, and has near-complete complex math support. tgmath should also work (fully on gcc-compatible compilers, and mostly on any c99 compiler). based largely on commit 0376d44a890fea261506f1fc63833e7a686dca19 from nsz's libm git repo, with some additions (dummy versions of a few missing long double complex functions, etc.) by me. various cleanups still need to be made, including re-adding (if they're correct) some asm functions that were dropped.	14 years ago
Rich Felker	d46cf2e14c	add .gitignore file I've had this around for a long time but somehow it never got committed.	14 years ago
Rich Felker	405ce58dcf	fix nan/infinity macros in math.h, etc. the previous version not only failed to work in c++, but also failed to produce constant expressions, making the macros useless as initializers for objects of static storage duration. gcc 3.3 and later have builtins for these, which sadly seem to be the most "portable" solution. the alternative definitions produce exceptions (for NAN) and compiler warnings (for INFINITY) on newer versions of gcc.	14 years ago
Rich Felker	b4a07bb469	fix obscure bug in strtoull reading the highest 16 possible values	14 years ago
Rich Felker	9fcecd7b34	typo in math.h c version check	14 years ago
Rich Felker	db3e78cee5	make math.h compatibe with c89	14 years ago
Rich Felker	6cf51fe51a	remove debug cruft that was left in getdate	14 years ago
Rich Felker	b93b7382d6	first try at implementing getdate function	14 years ago
Rich Felker	536db2b5ac	fix bugs in strptime handling of string day/month names, literals	14 years ago
Rich Felker	ca19774c91	implement a64l and l64a (legacy xsi stuff)	14 years ago
Rich Felker	e0614f7cd4	add all missing wchar functions except floating point parsers these are mostly untested and adapted directly from corresponding byte string functions and similar.	14 years ago
Rich Felker	899b13cae7	support null buffer argument to getcwd, auto-allocating behavior this is a popular extension some programs depend on, and by using a temporary buffer and strdup rather than malloc prior to the syscall, i've avoided the dependency on free and thus minimized the bloat cost of supporting this feature.	14 years ago
Rich Felker	051175d4fe	add memory.h, bogus legacy alias for string.h	14 years ago
Rich Felker	15d143b547	search internal headers first this is necessitated by the ugly <syscall.h> just added	14 years ago
Rich Felker	d36751943a	use c++-friendly initializers for pthread initializer definitions these will also avoid obnoxious warnings with gcc -Wbraces.	14 years ago
Rich Felker	4ce6766a32	add <syscall.h> as an alias for <sys/syscall.h> apparently some broken stuff (libstdc++) needs this.	14 years ago
Rich Felker	95b930ad26	implement wcsftime function	14 years ago
Rich Felker	b1a8e0d454	release notes for 0.8.6	14 years ago
Rich Felker	e3234d0109	fix pthread_cleanup_pop(1) crash in non-thread-capable, static-linked programs	14 years ago
Rich Felker	aab33ec0a3	update release notes for 0.8.5	14 years ago
Rich Felker	dac084a4c5	work around "signal loses thread pointer" issue with "approach 2" this was discussed on the mailing list and no consensus on the preferred solution was reached, so in anticipation of a release, i'm just committing a minimally-invasive solution that avoids the problem by ensuring that multi-threaded-capable programs will always have initialized the thread pointer before any signal handler can run. in the long term we may switch to initializing the thread pointer at program start time whenever the program has the potential to access any per-thread data.	14 years ago
Rich Felker	834255a3ff	use __attribute__((const)) on arm __pthread_self function	14 years ago
Rich Felker	06aec8d715	replace prototype for basename in string.h with non-prototype declaration GNU programs may expect the GNU version of basename, which has a different prototype (argument is const-qualified) and prototype it themselves too. of course if they're expecting the GNU behavior for the function, they'll still run into problems, but at least this eliminates some compile-time failures.	14 years ago
Rich Felker	78e79d9d50	new attempt at working around the gcc 3 visibility bug since gcc is failing to generate the necessary ".hidden" directive in the output asm, generate it explicitly with an __asm__ statement...	14 years ago
Rich Felker	7fa29920ed	remove useless attribute visibility from definitions this was a failed attempt at working around the gcc 3 visibility bug affecting x86_64. subsequent patch will address it with an ugly but working hack.	14 years ago
Rich Felker	bae2e52bfd	cleanup and work around visibility bug in gcc 3 that affects x86_64 in gcc 3, the visibility attribute must be placed on both the declaration and on the definition. if it's omitted from the definition, the compiler fails to emit the ".hidden" directive in the assembly, and the linker will either generate textrels (if supported, such as on i386) or refuse to link (on targets where certain types of textrels are forbidden or impossible without further assumptions about memory layout, such as on x86_64). this patch also unifies the decision about when to use visibility into libc.h and makes the visibility in the utf-8 state machine tables based on libc.h rather than a duplicate test.	14 years ago
