Evan Cheng	4ca4bc6f95	Re-apply 101075 and fix it properly. Just reuse the debug info of the branch instruction being optimized. There is no need to --I which can deref off start of the BB. ... llvm-svn: 101162	2010-04-13 18:50:27 +00:00
Eric Christopher	d67f66dc0c	Temporarily revert r101075, it's causing invalid iterator assertions ... in a nightly tester. llvm-svn: 101158	2010-04-13 18:37:58 +00:00

Bill Wendling	b02bbe416f	Micro-optimization: ... If we have this situation: jCC L1 jmp L2 L1: ... L2: ... We can get a small performance boost by emitting this instead: jnCC L2 L1: ... L2: ... This testcase shows an example of this: float func(float x, float y) { double product = (double)x * y; if (product == 0.0) return product; return product - 1.0; } llvm-svn: 101075	2010-04-12 22:19:57 +00:00

Chris Lattner	1eea3b0ada	Teach codegen to handle: ... (X != null) | (Y != null) --> (X|Y) != 0 (X == null) & (Y == null) --> (X|Y) == 0 so that instcombine can stop doing this for pointers. This is part of PR3351, which is a case where instcombine doing this for pointers (inserting ptrtoint) is pessimizing code. llvm-svn: 92406	2010-01-02 00:00:03 +00:00
