From: zhusonghe <[email protected]> The merged below patch modifies the __ieee754_sqrtf and __ieee754_sqrt functions to use a shared implementation, replacing the original fsqrt.d[s] instruction usage. patch:https://sourceware.org/git/?p=newlib-cygwin.git;a=commit;h=d572c4482b473d7725be0f9380d4f5d8342e4390 Signed-off-by: Songhe Zhu <[email protected]> --- newlib/libm/machine/riscv/e_sqrt.c | 1 + newlib/libm/machine/riscv/ef_sqrt.c | 1 + 2 files changed, 2 insertions(+) diff --git a/newlib/libm/machine/riscv/e_sqrt.c b/newlib/libm/machine/riscv/e_sqrt.c index 0c5aaadf3..ba000d36c 100644 --- a/newlib/libm/machine/riscv/e_sqrt.c +++ b/newlib/libm/machine/riscv/e_sqrt.c @@ -35,6 +35,7 @@ #include <math.h> #include "math_config.h" +#include "riscv_math.h" #if defined(__RISCV_HARD_FLOAT) && __RISCV_HARD_FLOAT >= 64 diff --git a/newlib/libm/machine/riscv/ef_sqrt.c b/newlib/libm/machine/riscv/ef_sqrt.c index cc41813dd..fd7ab4b41 100644 --- a/newlib/libm/machine/riscv/ef_sqrt.c +++ b/newlib/libm/machine/riscv/ef_sqrt.c @@ -35,6 +35,7 @@ #include <math.h> #include "math_config.h" +#include "riscv_math.h" #if defined(__RISCV_HARD_FLOAT) && __RISCV_HARD_FLOAT >= 32 -- 2.17.1
