* Avoid evaluating Neon macro arguments more than once by disabling type checks.Bob Wilson2011-08-15
| | | | | | | | | | It turns out that the use of "__extension__" in these macros was disabling the expected "incompatible pointer" warnings, so these type checks were not doing anything anyway. They introduced a serious bug by evaluating some macro arguments twice, which is a big problem for arguments with side effects. I'll have to find another way to get the right type checking.

* MCTargetAsmParser target match predicate support.Jim Grosbach2011-08-15
| | | | | | | | | | Allow a target assembly parser to do context sensitive constraint checking on a potential instruction match. This will be used, for example, to handle Thumb2 IT block parsing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137675 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | No need for it to be redefined as part of every derived target asm parser class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137649 91177308-0d34-0410-b5e6-96231b3b80d8
* Make Record Name an InitDavid Greene2011-08-10
| | | | | | | | | | | Use an Init (ultimately a StringInit) to represent the Record name. This allows the name to be composed by standard TableGen operators. This will enable us to get rid of the ugly #NAME# hack processing and naturally replace it with operators. It also increases flexibility and power of the TableGen language by allowing record identifiers to be computed dynamically. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137232 91177308-0d34-0410-b5e6-96231b3b80d8
* Add getAsUnquotedStringDavid Greene2011-08-10
| | | | | | | | | | | Add a method to return an Init as an unquoted string. This primarily affects StringInit where we return the value without surrounding it with quotes. This is in preparation for removing the ugly #NAME# hack and replacing it with standard TabelGen operators. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137231 91177308-0d34-0410-b5e6-96231b3b80d8

* Replace the existing ARM disassembler with a new one based on the ↵Owen Anderson2011-08-09
| | | | | | | | | | | FixedLenDecoderEmitter. This new disassembler can correctly decode all the testcases that the old one did, though some "expected failure" testcases are XFAIL'd for now because it is not (yet) as strict in operand checking as the old one was. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137144 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM refactoring assembly parsing of memory address operands.Jim Grosbach2011-08-03
| | | | | | | | | | | | | | | | | | | | | | | | Memory operand parsing is a bit haphazzard at the moment, in no small part due to the even more haphazzard representations of memory operands in the .td files. Start cleaning that all up, at least a bit. The addressing modes in the .td files will be being simplified to not be so monolithic, especially with regards to immediate vs. register offsets and post-indexed addressing. addrmode3 is on its way with this patch, for example. This patch is foundational to enable going back to smaller incremental patches for the individual memory referencing instructions themselves. It does just enough to get the basics in place and handle the "make check" regression tests we already have. Follow-up work will be fleshing out the details and adding more robust test cases for the individual instructions, starting with ARM mode and moving from there into Thumb and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136845 91177308-0d34-0410-b5e6-96231b3b80d8

* [AVX] Make TernOpInit UniqueDavid Greene2011-07-29
| | | | | | | | Make sure TernOpInits are unique and created only once. This will be important for AVX/SIMD as many operators will be used to generate patterns and other relevant data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136496 91177308-0d34-0410-b5e6-96231b3b80d8

* [AVX] Make ListInits UniqueDavid Greene2011-07-29
| | | | | | | | | Ensure ListInits are unique and only created once. This will be important for AVX as lists will be used extensively to pass generic patterns, prefix information and other things to lower-level pattern-generation classes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136493 91177308-0d34-0410-b5e6-96231b3b80d8

* [AVX] Make StringInit UniqueDavid Greene2011-07-29
| | | | | | | | Use a StringMap to ensure the StringInits are unique. This is especially important for AVX where we will have many smallish strings representing instruction prefixes, suffixes and the like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136491 91177308-0d34-0410-b5e6-96231b3b80d8

* [AVX] Create Inits Via Factory MethodDavid Greene2011-07-29

* [AVX] Constify InitsDavid Greene2011-07-29
| | | | | | | Make references to Inits const everywhere. This is the final step before making them unique. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136485 91177308-0d34-0410-b5e6-96231b3b80d8
* [AVX] Remove non-const IteratorsDavid Greene2011-07-29
| | | | | | | | Remove all non-const iterators from Init classes. This is another step toward constifying Inits and ultimately turning them into FoldingSetNodes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136484 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a std::string Wrapper for TableGenDavid Greene2011-07-29
| | | | | | | | | Create a std::string wrapper for use as a DenseMap key. DenseMap is not safe in generate with strings, so this wrapper indicates that only strings guaranteed not to have certain values should be used in the DenseMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136481 91177308-0d34-0410-b5e6-96231b3b80d8
