* LoopVectorize: Simplify code for clarity.Benjamin Kramer2013-02-131-10/+8
| | | | | | No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175076 91177308-0d34-0410-b5e6-96231b3b80d8
* For Mips 16, add the optimization where the 16 bit form of addiu sp can be usedReed Kotler2013-02-133-3/+46
| | | | | | | | | | | | if the offset fits in 11 bits. This makes use of the fact that the abi requires sp to be 8 byte aligned so the actual offset can fit in 8 bits. It will be shifted left and sign extended before being actually used. The assembler or direct object emitter will shift right the 11 bit signed field by 3 bits. We don't need to deal with that here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175073 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: Disable generation of rep;movsl when %esi is used as a base pointer.Benjamin Kramer2013-02-131-0/+8
| | | | | | | | | | | This happens when there is both stack realignment and a dynamic alloca in the function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the base pointer and the next register spill will write into oblivion. Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas and freebsd a 4 byte stack alignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175057 91177308-0d34-0410-b5e6-96231b3b80d8

* [ms-inline asm] Add support for lexing binary integers with a [bB] suffix.Chad Rosier2013-02-121-19/+40
| | | | | | | | | | | | | | | This is complicated by backward labels (e.g., 0b can be both a backward label and a binary zero). The current implementation assumes [0-9]b is always a label and thus it's possible for 0b and 1b to not be interpreted correctly for ms-style inline assembly. However, this is relatively simple to fix in the inline assembly (i.e., drop the [bB]). This patch also limits backward labels to [0-9]b, so that only 0b and 1b are ambiguous.

| | | | | | | | | | | Vectors were being manually scalarized by the backend. Instead, let the target-independent code do all of the work. The manual scalarization was from a time before good target-independent support for scalarization in LLVM. However, this forces us to specially-handle vector loads and stores, which we can turn into PTX instructions that produce/consume multiple operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174968 91177308-0d34-0410-b5e6-96231b3b80d8
