2010-10-22libm/x86: use call instead of jump for wrappersTimo Teräs
GCC can emit prologue/epilogue code for the functions in various different cases: - frame pointers - PIC build (to load ebx for indirect calls/jumps) - forced stack smashing protection If we used jump in such cases, we'd corrupt the call stack and crash.

Fixes signgam checks in math tests on x86_64. It's R_X86_64_COPY for program, so the program didn't see any changes from libm. Signed-off-by: Roman I Khimov <khimov@altell.ru> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2010-04-22nptl: proper soname handlingNatanael Copa
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.

2009-02-17libm/Makefile.in: reformat the list of wrappersDenis Vlasenko
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.
