Evan Cheng aaf414c92c Favors generating "not" over "xor -1". For example. ... unsigned test(unsigned a) { return ~a; } llvm used to generate: movl $4294967295, %eax xorl 4(%esp), %eax Now it generates: movl 4(%esp), %eax notl %eax It's 3 bytes shorter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@62661 91177308-0d34-0410-b5e6-96231b3b80d8		2009-01-21 02:09:05 +00:00

PowerPC	Fix PPC ISD::Declare isel and eliminate the need for PPCTargetLowering::LowerGlobalAddress to check if isVerifiedDebugInfoDesc() is true. Given the recent changes, it would falsely return true for a lot of GlobalAddressSDNode's.	2009-01-16 22:57:32 +00:00
