* Revert "libm: fix C99_MATH on __NO_LONG_DOUBLE_MATH hosts"Bernhard Reutner-Fischer2009-11-148-28/+44
| | | | | | | | This reverts commit 73d6e5c41b61633e22ea74e3aa2df721512dca57. barking up the wrong tree Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* libm: fix C99_MATH on __NO_LONG_DOUBLE_MATH hostsBernhard Reutner-Fischer2009-11-148-44/+28
| | | | | | | alias l to their normal double counterparts. Works around problems with libgcc blindly calling __finitel on e.g. ppc32 Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* honour NO_LONG_DOUBLE_MATHBernhard Reutner-Fischer2009-08-302-1/+11
| | | | | | | | This fixes compilation errors on hosts that turn off long double support for C99 like powerpc32. Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

* Add a few missing includesRon2009-07-051-0/+1
| | | | | | | | elf.h needs __BYTE_ORDER, and s_scalbn.c needs {LONG,INT}_MAX. shm.c complains about no prototypes for shm_{open,unlink} without its header. Signed-off-by: Ron Lee <ron@debian.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* libm/Makefile.in: reformat the list of wrappersDenis Vlasenko2009-02-172-22/+127
| | | | | | | | | | | | | | | so that it is easier to modify, sort, etc; use __ in filenames of wrappers which wrap __functions (it may be useful to have function and file names ALWAYS match); remove names of not implemented wrappers (it was generating useless empty .o files). libm/ldouble_wrappers.c: comment out the wrapper which is not compiled anyway test/math/compile_test.c: improve this test, it was optimizing out some calls, and we don't want that. No actual code changes.
* test/math/compile_test.c: "are long double functions even compile/link?" testDenis Vlasenko2009-02-172-4/+31
| | | | | *: fix everything which prevents above from building
* math.h: fix libm_hidden_proto leak into sanitized headersDenis Vlasenko2009-02-141-4/+4

* docs/probe_math_exception.c:Denis Vlasenko2009-02-113-21/+41
| | | | | | | | | | | | update example libc/sysdeps/linux/i386/bits/mathinline.h: improve __finite() macro, add __finitef macro (why they aren't always macros? why aren't they arch independent?) libm/math_private.h: much better comments on math_opt_barrier() and math_force_eval() libm/s_finite[f].c: improve out-of-line __finite[f]() too (one byte less, yay...)
