Brian Gaeke 84a69f1494 Solaris hack for isinf()
llvm-svn: 15058
2004-07-21 03:32:51 +00:00
Brian Gaeke a5adf7948c Add check for finite(). Solaris doesn't have isinf, but it has finite...go
figure!

Chris Lattner 4e2dbc6b4a Rewrite cast->cast elimination code completely based on the information we
actually care about.  Someday when the cast instruction is gone, we can do
better here, but this will do for now.  This implements
instcombine/cast.ll:test17/18 as well.

John Criswell b92c7c2270 Added support for stdint.h. It is now automatically included by
DataTypes.h.  So far, it doesn't seem to break Linux, Solaris, or MacOS X.
This should automatically include it for those people who need it.

Chris Lattner c8fb1fb5bb When joining intervals, join intervals in deeply nested loops first. This
is a simple change, but seems to improve code a little.  For example, on
256.bzip2, we went from 75.0s -> 73.33s (2% speedup).
