2023-03-13LoongArch: Add get_rounding_mode.caiyinyu1-0/+38
2023-02-27LoongArch: Add math-barriers.hXi Ruoyao1-0/+28
This patch implements the LoongArch specific math barriers in order to omit the store and load from stack if possible. Signed-off-by: Xi Ruoyao <xry111@xry111.site> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

2022-11-29LoongArch: Add support for ilogb[f]Xiaolin Tang2-0/+78
Add inline assembler for the ilogb functions. Passes GLIBC regression.
2022-11-29LoongArch: Add support for scalb[f]Xiaolin Tang2-0/+120
Add inline assembler for the scalb functions. Passes GLIBC regression.
2022-11-29LoongArch: Add support for scalbn[f]Xiaolin Tang2-0/+58
Add inline assembler for the scalbn functions. Passes GLIBC regression. GCC 13, LoongArch support ___builtin_scalbn{,f} with -fno-math-errno, but only "libm" can use -fno-math-errno in GLIBC, and scalbn is in libc instead of libm because __printf_fp calls it.
