[PATCH] [BZ #2749] ports powerpc32/nofpu fixes.
- From: Steven Munroe <munroesj at us dot ibm dot com>
- To: libc-ports at sources dot redhat dot com, Joe Kerian <jkerian at linux dot ibm dot com>, "Joseph S. Myers" <joseph at codesourcery dot com>

- Subject: [PATCH] [BZ #2749] ports powerpc32/nofpu fixes.
- Organization: IBM LTC
This patch fixes powerpc32/soft-fp specific build issues, work arounds
for exsisting gcc bugs, and provide nofpu specific implementation of the
*context functions to avoid sigills on hardware without-fpu. Finally
updated the libm-test-ulps for the nominal differences between IEEE-128
and IBM extended 128.
