The other 3 cases of the same: https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/ieee754/soft-fp/s_fma.c;h=41cf81a74bfc6a8c21c565fb04c90ced4bfd19e8;hb=refs/heads/master#l32 https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/ieee754/soft-fp/s_fmaf.c;h=afe64356b3a9c5f3467c35b80f33ba946fbeee46;hb=refs/heads/master#l32 https://sourceware.org/git/?p=glibc.git;a=blob;f=sysdeps/ieee754/soft-fp/s_fmal.c;h=4c2d4c5d9be09f0c8464fb20b81af3aff131e65d;hb=refs/heads/master#l32 are probably also triggered only with -O1, do you want me to update all 4 or just the new case? -- Martin 'JaMa' Jansa jabber: Martin.Jansa@gmail.com
