* Many Thumb2 instructions can reference the full ARM register set (i.e.,Jim Grosbach2010-07-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | have 4 bits per register in the operand encoding), but have undefined behavior when the operand value is 13 or 15 (SP and PC, respectively). The trivial coalescer in linear scan sometimes will merge a copy from SP into a subsequent instruction which uses the copy, and if that instruction cannot legally reference SP, we get bad code such as: mls r0,r9,r0,sp instead of: mov r2, sp mls r0, r9, r0, r2 This patch adds a new register class for use by Thumb2 that excludes the problematic registers (SP and PC) and is used instead of GPR for those operands which cannot legally reference PC or SP. The trivial coalescer explicitly requires that the register class of the destination for the COPY instruction contain the source register for the COPY to be considered for coalescing. This prevents errant instructions like that above. PR7499 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109842 91177308-0d34-0410-b5e6-96231b3b80d8

* Start the support for AVX instructions with 256-bit %ymm registers. A couple ofBruno Cardoso Lopes2010-07-091-0/+2
| | | | | | | | | | | | | | | | | notes: - The instructions are being added with dummy placeholder patterns using some 256 specifiers, this is not meant to work now, but since there are some multiclasses generic enough to accept them, when we go for codegen, the stuff will be already there. - Add VEX encoding bits to support YMM - Add MOVUPS and MOVAPS in the first round - Use "Y" as suffix for those Instructions: MOVUPSYrr, ... - All AVX instructions in X86InstrSSE.td will move soon to a new X86InstrAVX file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@107996 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | call must not be callee-saved; following x86, add a new regclass to represent this. Also fixes a couple of bugs. Still disabled by default; Thumb doesn't work yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106053 91177308-0d34-0410-b5e6-96231b3b80d8
* Add instruction encoding for the Neon VMOV immediate instruction. This changesBob Wilson2010-06-111-4/+1
| | | | | | | | | | | | the machine instruction representation of the immediate value to be encoded into an integer with similar fields as the actual VMOV instruction. This makes things easier for the disassembler, since it can just stuff the bits into the immediate operand, but harder for the asm printer since it has to decode the value to be printed. Testcase for the encoding will follow later when MC has more support for ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@105836 91177308-0d34-0410-b5e6-96231b3b80d8

* Eliminated the classification of control registers into %ecr_Sean Callanan2010-05-061-2/+1

It used to #include the enhanced disassembly information for the targets it supported straight out of lib/Target/{X86,ARM,...} but now it uses a new interface provided by MCDisassembler, and (so far) implemented by X86 and ARM. Also removed hacky #define-controlled initialization of targets in edis. If clients only want edis to initialize a limited set of targets, they can set --enable-targets on the configure command line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101179 91177308-0d34-0410-b5e6-96231b3b80d8
