* 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.

| | | | | | | | This reverts commit 73d6e5c41b61633e22ea74e3aa2df721512dca57. barking up the wrong tree Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

| | | | | | | 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>

* 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

| | | | | | | | | | | | 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...)
