2005-06-18new vararg testAndrew Lenharth

2005-06-18OK, after checking the backwards compatibility code on X86 and the new codeAndrew Lenharth
path on alpha, now has come the time for new vararg support. So, with out further ado, I revert behavior back a couple of years! Well, ok, I lied. A few more notes. First, the Simple ISels cannot be expected to work any longer, but they should still compile Second, there are likely some bugs to track down once the nightly testers start with this. Third, the initial patch doesn't include sparcv9, but I'll do that today. Forth, subsequent patches won't bother being long winded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22251 91177308-0d34-0410-b5e6-96231b3b80d8

2005-06-12When compiled with GCC 4.0, a latent bug was exposed where both SparcV9Nate Begeman
