* libm: implement a generic sincos().William Pitcock2011-11-041-1/+1
| | | | | | | We already provide sincos() on some archs, so we should ship a generic version. Signed-off-by: William Pitcock <nenolod@dereferenced.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* libm: implement generic cexp(), cexpf() and cexpl().William Pitcock2011-11-041-1/+2
| | | | | | | | The cexp*() family of functions is defined by the C99 math standard as implementing exponential functions for complex types. Signed-off-by: William Pitcock <nenolod@dereferenced.org> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* libm: fix building out-of-treeBernhard Reutner-Fischer2011-05-121-1/+1
| | | | | | Thanks to Thierry Reding for noticing! Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
* Add Makefile support for DSBT ELF.Bernd Schmidt bernds_cb1@t-online.de2011-03-051-0/+1
| | | | | | | | | | | This adds support for a new binary format, DSBT ELF, to the Makefiles. Every shared library is assigned a DSBT index, and the link.so macro is adjusted to ensure the correct linker argument is passed. Configuration and ldso support will follow in separate commits.

* libm_powerpc: update buildsys to use TARGET_SUBARCHCarmelo Amoroso2010-12-171-11/+0
| | | | | | | | Update the powerpc buildsys of libm to use the TARGET_SUBARCH. Further fix the e500 Makefile.arch by adding the definition of libm_ARCH_fpu_DIR that was actually missing. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* libm_sh: Move fenv functions into sh4 sub-folderCarmelo Amoroso2010-12-171-0/+7
| | | | | | | Indeed fenv funxtions are SH4 specific, so move them into an SH4 specific sub-folder. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
* nptl: proper soname handlingNatanael Copa2010-04-221-2/+2
| | | | | | | | | | | Since sublevel releases are not ABI compatible we need to adjust the soname to include the sublevel version. This makes it possible to install ABI incompatible versions of the library side by side so clean upgrades are possible.

* Revert "libm: fix C99_MATH on __NO_LONG_DOUBLE_MATH hosts"Bernhard Reutner-Fischer2009-11-141-0/+5
| | | | | | | | 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-Fischer2009-11-141-5/+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>

* libm/Makefile.in: reformat the list of wrappersDenis Vlasenko2009-02-171-17/+120
| | | | | | | | | | | | | | | 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/+2
| | | | | *: fix everything which prevents above from building
* ldouble_wrappers.c: fix __signbitl, it was calling itself by mistake.Denis Vlasenko2009-02-091-1/+1
| | | | | | remove wrong casts to long double of long return values. remove lots of empty lines.

* libm: add scalbf, gammaf, significandf wrappers.Denis Vlasenko2009-02-051-1/+1
| | | | | | This makes in possible to enable test/math (not it compiles, but has lots of test failures).

* libm: remove scalbln implementation, it seems to be less correct than scalbn.Denis Vlasenko2009-01-031-2/+1
| | | | | | | | | | instead, either alias scalbln to scalbn if int == long on this arch, or just call scalbn form scalbln. text data bss dec hex filename - 45297 180 4 45481 b1a9 lib/libm.so + 44969 180 4 45153 b061 lib/libm.so
