* LoongArch: Add math-barriers.hXi Ruoyao2023-02-271-0/+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>

* LoongArch: Add support for ilogb[f]Xiaolin Tang2022-11-292-0/+78
| | | | Add inline assembler for the ilogb functions. Passes GLIBC regression.
* LoongArch: Add support for scalb[f]Xiaolin Tang2022-11-292-0/+120
| | | | Add inline assembler for the scalb functions. Passes GLIBC regression.
* LoongArch: Add support for scalbn[f]Xiaolin Tang2022-11-292-0/+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.
