* sparc nptl needs it's own lowlevellock.caustinf2009-03-214-4/+157
| | | | | * Since sparc < v9 doesn't have a real compare exchange instruction, we implement it with a test and set.

* sparc32 nptl functionalaustinf2009-03-1927-254/+940
| | | | | | | | | * pulled updated asm and headers from glibc for sparc32 * probably no cancellation support yet * no shared TLS relocs yet, since ldso is hosed on sparc still note: didn't use TARGET_SUBARCH method of includes since that would cause other parts of libc to fail currently. Will need to be fixed later.
* Always compile fork.S in arm mode. Make _Unwind_Resume arm onlyKhem Raj2009-03-182-1/+13

| | | | | | | | | | | | | | | 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.
