2008-05-26The Linux ABI emits an extra "movl %esp, %ebp" in function prologue andNick Lewycky
sometimes a "mov %ebp, %esp" in the epilogue. Force these tests that rely on counting 'mov' to use i686-apple-darwin8.8.0 where they were written. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51568 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-26Factor code to copy global value attributes likeDuncan Sands
the section or the visibility from one global value to another: copyAttributesFrom. This is particularly useful for duplicating functions: previously this was done by explicitly copying each attribute in turn at each place where a new function was created out of an old one, with the result that obscure attributes were regularly forgotten (like the collector or the section). Hopefully now everything is uniform and nothing is forgotten. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51567 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-26A problem that's exposed when machine LICM is enabled. Consider this code:Bill Wendling
LBB1_3: # bb ... xorl %ebp, %ebp subl (%ebx), %ebp ... incl %ecx cmpl %edi, %ecx jl LBB1_3 # bb Whe using machine LICM, LLVM converts it into: xorl %esi, %esi LBB1_3: # bb ... movl %esi, %ebp subl (%ebx), %ebp ... incl %ecx cmpl %edi, %ecx jl LBB1_3 # bb Two address conversion inserts the copy instruction. However, it's cheaper to rematerialize it, and remat helps reduce register pressure. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@51562 91177308-0d34-0410-b5e6-96231b3b80d8

Analysis/ConstantFolding to fold ConstantExpr's, then make instcombine use it to try to use targetdata to fold constant expressions on void instructions.
