From 845e4f6692336ea7f7672045dee05fa39c4022ec Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 2 Aug 2020 23:31:51 -0400 Subject: add m68k sqrtl using native instruction this is actually a functional fix at present, since the C sqrtl does not support ld80 and just wraps double sqrt. once that's fixed it will just be an optimization. --- src/math/m68k/sqrtl.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) create mode 100644 src/math/m68k/sqrtl.c diff --git a/src/math/m68k/sqrtl.c b/src/math/m68k/sqrtl.c new file mode 100644 index 00000000..b1c303c7 --- /dev/null +++ b/src/math/m68k/sqrtl.c @@ -0,0 +1,15 @@ +#include + +#if __HAVE_68881__ + +long double sqrtl(long double x) +{ + __asm__ ("fsqrt.x %1,%0" : "=f"(x) : "fm"(x)); + return x; +} + +#else + +#include "../sqrtl.c" + +#endif -- cgit v1.2.1
