* R600: Support for indirect addressing v4Tom Stellard2013-02-0630-75/+1124
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Only implemented for R600 so far. SI is missing implementations of a few callbacks used by the Indirect Addressing pass and needs code to handle frame indices. At the moment R600 only supports array sizes of 16 dwords or less. Register packing of vector types is currently disabled, which means that a vec4 is stored in T0_X, T1_X, T2_X, T3_X, rather than T0_XYZW. In order to correctly pack registers in all cases, we will need to implement an analysis pass for R600 that determines the correct vector width for each array. v2: - Add support for i8 zext load from stack. - Coding style fixes v3: - Don't reserve registers for indirect addressing when it isn't being used. - Fix bug caused by LLVM limiting the number of SubRegIndex declarations. v4: - Fix 64-bit defines git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174525 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement external weak (ELF) symbols on AArch64Tim Northover2013-02-063-4/+30
| | | | | | | | | Weakly defined symbols should evaluate to 0 if they're undefined at link-time. This is impossible to do with the usual address generation patterns, so we should use a literal pool entry to materlialise the address. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174518 91177308-0d34-0410-b5e6-96231b3b80d8

* Add AArch64 CRC32 instructionsTim Northover2013-02-063-1/+53
| | | | | | | | These instructions are a late addition to the architecture, and may yet end up behind an optional attribute, but for now they're available at all times. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174496 91177308-0d34-0410-b5e6-96231b3b80d8
* Add icache prefetch operations to AArch64Tim Northover2013-02-064-0/+62
| | | | | | | This adds hints to the various "prfm" instructions so that they can affect the instruction cache as well as the data cache. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174495 91177308-0d34-0410-b5e6-96231b3b80d8
* Initial submission for the attribute group feature.Bill Wendling2013-02-066-41/+197
| | | | | | | | | | | | | | | | | | Attribute groups are of the form: #0 = attributes { noinline "no-sse" "cpu"="cortex-a8" alignstack=4 } Target-dependent attributes are represented as strings. Attributes can have optional values associated with them. E.g., the "cpu" attribute has the value "cortex-a8". Target-independent attributes are listed as enums inside the attribute classes. Multiple attribute groups can be referenced by the same object. In that case, the attributes are merged together. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174493 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: Use MCTargetAsmParser::validateTargetOperandClass().Jim Grosbach2013-02-061-47/+19
| | | | | | | | | | | Use the validateTargetOperandClass() hook to match literal '#0' operands in InstAlias definitions. Previously this required per-instruction C++ munging of the operand list, but not is handled as a natural part of the matcher. Much better. No additional tests are required, as the pre-existing tests for these instructions exercise the new behaviour as being functionally equivalent to the old. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174488 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow targets to add custom asm operand matching logic.Jim Grosbach2013-02-062-0/+18
| | | | | | | | | | For example, ARM has several instructions with a literal '#0' immediate in the syntax that's not represented as an actual operand. The asm matcher is expected a token operand, but the parser will have created an immediate operand. This is currently handled by dedicated per-instruction C++ munging of the ParsedAsmOperand list, but will be better handled by this hook. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174487 91177308-0d34-0410-b5e6-96231b3b80d8

* Preprocess Apple llvmCore headers to reflect NDEBUG setting. <rdar://12568983>Bob Wilson2013-02-051-0/+10
| | | | | | | | | | If an Apple llvmCore build is done without assertions, and a client uses the llvmCore headers with assertions enabled, or vice versa, then things will break because some of the structure sizes in the API are different.
