2005-05-12Fix this test on Solaris.John Criswell
Solaris grep is more traditional and (AFAIK) does not support regexs. Also, single quotes should disable all shell interpretation, so no backslashes should be needed (and, in fact, keep Solaris from working). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21902 91177308-0d34-0410-b5e6-96231b3b80d8

2005-05-11fix and concisify intinsic lowering for ctpop. Unfortunately, this codeChris Lattner
looks completely untested. :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21873 91177308-0d34-0410-b5e6-96231b3b80d8
2005-05-11Fix the last remaining bug preventing us from switching the X86 BE overChris Lattner
from the simple isel to the pattern isel. This forces inserted libcalls to serialize against other function calls, which was breaking UnitTests/2005-05-12-Int64ToFP. Hopefully this will fix issues on other targets as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21872 91177308-0d34-0410-b5e6-96231b3b80d8

2005-05-11Legalize for CTLZ generates a ctpop, but this ctpop is not expanded.Andrew Lenharth
This is bad. It is generated if you are ctlz a type that is not legal for the arch (aka ctlz of bytes on alpha legalize fine). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@21867 91177308-0d34-0410-b5e6-96231b3b80d8
