An updated ia64 floating point patch for glibc
- To: ia64-tools at napali dot hpl dot hp dot com
- Subject: An updated ia64 floating point patch for glibc
- From: "H . J . Lu" <hjl at valinux dot com>
- Date: Fri, 8 Dec 2000 18:44:30 -0800
- Cc: GNU C Library <libc-alpha at sourceware dot cygnus dot com>
I implemented a few more floating point functions. They passed
"make check" in glibc.
