Mark Murray 292815eac6 Fix powf(). ... Summary: From Steve Kargl: Paul Zimmermann has identified a bug in Openlibm's powf(), which is identical to FreeBSD's libm. Both derived from fdlibm. https://github.com/JuliaMath/openlibm/issues/212. Consider % cat h.c int main(void) { float x, y, z; x = 0x1.ffffecp-1F; y = -0x1.000002p+27F; z = 0x1.557a86p115F; printf("%e %e %e <-- should be %e\n", x, y, powf(x,y), z); return 0; } % cc -o h -fno-builtin h.c -lm && ./h 9.999994e-01 -1.342177e+08 inf <-- should be 5.540807e+34 Reviewers: manu Subscribers: imp, andrew, emaste Differential Revision: https://reviews.freebsd.org/D31865		2021-09-06 18:51:31 +01:00
