* ARM assembly aliases for add negative immediates using sub.Jim Grosbach2012-04-054-5/+76
| | | | | | | | | | 'add r2, #-1024' should just use 'sub r2, #1024' rather than erroring out. Thumb1 aliases for adding a negative immediate to the stack pointer, also. rdar://11192734 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154123 91177308-0d34-0410-b5e6-96231b3b80d8

* Don't break the IV update in TLI::SimplifySetCC().Jakob Stoklund Olesen2012-04-053-23/+72
| | | | | | | | | | | | | | | | | | | LSR always tries to make the ICmp in the loop latch use the incremented induction variable. This allows the induction variable to be kept in a single register. When the induction variable limit is equal to the stride, SimplifySetCC() would break LSR's hard work by transforming: (icmp (add iv, stride), stride) --> (cmp iv, 0) This forced us to use lea for the IC update, preventing the simpler incl+cmp. <rdar://problem/7643606> <rdar://problem/11184260> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154119 91177308-0d34-0410-b5e6-96231b3b80d8

* In MemoryBuffer::getOpenFile() make sure that the buffer is null-terminated ifArgyrios Kyrtzidis2012-04-051-0/+11
| | | | | | | | | | | | | the caller requested a null-terminated one. When mapping the file there could be a racing issue that resulted in the file being larger than the FileSize passed by the caller. We already have an assertion for this in MemoryBuffer::init() but have a runtime guarantee that the buffer will be null-terminated, so do a copy that adds a null-terminator.

* Pass the right sign to TLI->isLegalICmpImmediate.Jakob Stoklund Olesen2012-04-052-2/+15
| | | | | | | | | | | | | | | | | | LSR can fold three addressing modes into its ICmpZero node: ICmpZero BaseReg + Offset => ICmp BaseReg, -Offset ICmpZero -1*ScaleReg + Offset => ICmp ScaleReg, Offset ICmpZero BaseReg + -1*ScaleReg => ICmp BaseReg, ScaleReg The first two cases are only used if TLI->isLegalICmpImmediate() likes the offset. Make sure the right Offset sign is passed to this method in the second case. The ARM version is not symmetric. <rdar://problem/11184260> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154079 91177308-0d34-0410-b5e6-96231b3b80d8
