Subject: [PATCH 0/1] RISC-V: Add math functions
From: zhangfei <zhangfei@...iscas.ac.cn>
Hi,
I added 8 math function implementations for riscv64.These functions
are implemented using riscv floating-point instructions instead of C
implementations.There is a similar implementation in glibc:
[1] https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/riscv/rv64/rvd/s_llrint.c;h=0fbe8e2d68977f05e2f37a2dc52e00ce005c37b8;hb=HEAD
[2] https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/riscv/rv64/rvd/s_llround.c;h=f3c6275c9f9b81e9c4ce626be0d379c005eee986;hb=HEAD
...
I used libc-test on the RISC-V SiFive U74 to do the test,and there was
no error in lrint and other test items.
Thanks,
Zhang Fei
