High quality system independent, portable, open source libm implementation
When I went through openlibm_fenv_i387.h and added `OLM_DLLEXPORT`, it felt like the `__has_sse`/`__test_sse` symbols should have been private, but they were used by the tests so had to be exported....
Hello, An error occurred when cross compiling with ARCH = aarch64 , the error message says: `aarch64/fenv.c:40:29: error: invalid initializer const fenv_t __fe_dfl_env = `0; how can i solve it?
This example was pointed out by njuffa on scicomp.stackexchange.com. I checked it also with a recent version of Z3 and exact rational arithmetic. ``` # This is the native cpu...
I just ran benchmarks of openlibm (compiled by gcc and clang) and system libm (Glibc), and these were the results: ``` openlibm(gcc) syslibm openlibm(clang) pow : 17.4427 MPS : 69.7010...
with the attached program I get with OpenLibm 0.7.4: $ gcc -fno-builtin test_pow_openlibm.c /localdisk/zimmerma/openlibm-0.7.4/libopenlibm.a -fopenmp $ OMP_NUM_THREADS=1 ./a.out nthreads=1 $ OMP_NUM_THREADS=2 ./a.out nthreads=2 Error for powl(0x8.779021e7c2f81b2p+14982,-0x8.0021b03e1f821c9p-15097), expected 1, got 0x8.8980e8092da8445p-3...
The [musl libm](https://git.musl-libc.org/cgit/musl/tree/src/math) looks really good and reasonably updated. It would be worthwhile to see if we can set up some scripts to extract to update openlibm. Ideally - we'd...
Are there stubs of functions that operate with long double types like `roundl()`, `sinl()` and so on? I can not find it. I found such stubs in glibc and newlib,...

the attached program gives +Inf for x=-0xd.b6e8f5c28f5c29p+7l, whereas glibc gives 0x0.01dbd551da54538p-16385 which is the correctly rounded result. [test_tgamma_openlibm.c.gz](https://github.com/JuliaMath/openlibm/files/5923918/test_tgamma_openlibm.c.gz)
