[PATCH] Sparc exp(), expf() performance improvement

[Patrick McGehearty]

I want to thank David Miller, Carlos O'Donell, Joseph Myers, and 
Adhemerval Zanella
for their helpful comments on improving the patch I'm proposing for
Sparc exp(), expf().

I will be going on vacation after tomorrow, returning after the USA 
Solar eclipse (Aug 21).
As it is generally considered 'bad form' to submit code to a shared 
project and then
disappear for a time, I plan to work on this patch tomorrow but hold off 
my next PATCH
submission until I get back.

Just sending this message so you all won't think I've disappeared into 
the ether.  :-)
