* Revert "libm: fix C99_MATH on __NO_LONG_DOUBLE_MATH hosts"Bernhard Reutner-Fischer2009-11-141-0/+39
| | | | | | | | 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-Fischer2009-11-141-39/+0
| | | | | | | 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-Fischer2009-08-301-0/+10
| | | | | | | | 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>
* libm/Makefile.in: reformat the list of wrappersDenis Vlasenko2009-02-171-5/+7
| | | | | | | | | | | | | | | 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 Vlasenko2009-02-171-2/+29
| | | | | *: fix everything which prevents above from building
