[PATCH] Sparc optimized fmin{,f} and fmax{,f}.
- From: David Miller <davem at davemloft dot net>
- To: libc-alpha at sourceware dot org
- Date: Thu, 15 Mar 2012 02:16:25 -0700 (PDT)
- Subject: [PATCH] Sparc optimized fmin{,f} and fmax{,f}.
Ok, this adds optimized fmin/fmax for sparc, including the
VIS3 cases using the lexicographic compare instructions I
explained earlier this evening.
Committed to master.
