Alp Toker	1c4b33e8e5	Fix known typos ... Sweep the codebase for common typos. Includes some changes to visible function names that were misspelt. llvm-svn: 200018	2014-01-24 17:20:08 +00:00
Richard Sandiford	533c977c68	[SystemZ] Optimize fcmp X, 0 in cases where X is also negated ... In such cases it's often better to test the result of the negation instead, since the negation also sets CC. llvm-svn: 197032	2013-12-11 11:45:08 +00:00
Richard Sandiford	344b7e5ec3	[SystemZ] Use LOAD AND TEST for comparisons with -0 ... ...since it os equivalent to comparison with +0. llvm-svn: 196580	2013-12-06 09:59:12 +00:00
Richard Sandiford	b6323e0b21	[SystemZ] Optimize floating-point comparisons with zero ... This follows the same lines as the integer code. In the end it seemed easier to have a second 4-bit mask in TSFlags to specify the compare-like CC values. That eats one more TSFlags bit than adding a CCHasUnordered would have done, but it feels more concise. llvm-svn: 187883	2013-08-07 11:10:06 +00:00
