* [Modules] Make Support/Debug.h modular. This requires it to not changeChandler Carruth2014-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | behavior based on other files defining DEBUG_TYPE, which means it cannot define DEBUG_TYPE at all. This is actually better IMO as it forces folks to define relevant DEBUG_TYPEs for their files. However, it requires all files that currently use DEBUG(...) to define a DEBUG_TYPE if they don't already. I've updated all such files in LLVM and will do the same for other upstream projects. This still leaves one important change in how LLVM uses the DEBUG_TYPE macro going forward: we need to only define the macro *after* header files have been #include-ed. Previously, this wasn't possible because Debug.h required the macro to be pre-defined. This commit removes that. By defining DEBUG_TYPE after the includes two things are fixed: - Header files that need to provide a DEBUG_TYPE for some inline code can do so by defining the macro before their inline code and undef-ing it afterward so the macro does not escape. - We no longer have rampant ODR violations due to including headers with different DEBUG_TYPE definitions. This may be mostly an academic violation today, but with modules these types of violations are easy to check for and potentially very relevant. Where necessary to suppor headers with DEBUG_TYPE, I have moved the definitions below the includes in this commit. I plan to move the rest of the DEBUG_TYPE macros in LLVM in subsequent commits; this one is big enough. The comments in Debug.h, which were hilariously out of date already, have been updated to reflect the recommended practice going forward. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206822 91177308-0d34-0410-b5e6-96231b3b80d8

* TableGen: give asm match classes deterministic order.Tim Northover2013-09-16
| | | | | | | | | | | | | | | TableGen was sorting the entries in some of its internal data structures by pointer. This order filtered through to the final matching table and affected the diagnostics produced on bad assembly occasionally. It also turns out STL algorithms are ridiculously easy to misuse on containers with custom order methods. (No bugs before, or now that I know of, but plenty in the middle). This should fix the sanitizer bot, which ends up with weird pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190793 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an instruction deprecation feature to TableGen.Joey Gouly2013-09-12
| | | | | | | | | | | | | | | | | | | | | | | | The 'Deprecated' class allows you to specify a SubtargetFeature that the instruction is deprecated on. The 'ComplexDeprecationPredicate' class allows you to define a custom predicate that is called to check for deprecation. For example: ComplexDeprecationPredicate<"MCR"> would mean you would have to define the following function: bool getMCRDeprecationInfo(MCInst &MI, MCSubtargetInfo &STI, std::string &Info) Which returns 'false' for not deprecated, and 'true' for deprecated and store the warning message in 'Info'. The MCTargetAsmParser constructor was chaned to take an extra argument of the MCInstrInfo class, so out-of-tree targets will need to be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@190598 91177308-0d34-0410-b5e6-96231b3b80d8

* Stablize MCK_Reg ordering in AsmMatcherEmitterRichard Sandiford2013-08-12
| | | | | | | | | | | | | | | | clang bootstraps intermittently failed for me due a difference in the MCK_Reg ordering in ARMGenAsmMatcher.inc. E.g. in my latest run the stage 1 and stage 3 versions were the same but the stage 2 one was different (though still functionally correct). This meant that the .o comparison failed. MCK_Regs were assigned by iterating over a std::set< std::set<Record*> >, and since std::set is sorted lexicographically, the order depended on the order of the pointer values. This patch replaces the pointer ordering with LessRecordByID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188164 91177308-0d34-0410-b5e6-96231b3b80d8

* Handle tied sub-operands in AsmMatcherEmitterUlrich Weigand2013-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem this patch addresses is the handling of register tie constraints in AsmMatcherEmitter, where one operand is tied to a sub-operand of another operand. The typical scenario for this to happen is the tie between the "write-back" register of a pre-inc instruction, and the base register sub-operand of the memory address operand of that instruction. The current AsmMatcherEmitter code attempts to handle tied operands by emitting the operand as usual first, and emitting a CVT_Tied node when handling the second (tied) operand. However, this really only works correctly if the tied operand does not have sub-operands (and isn't a sub-operand itself). Under those circumstances, a wrong MC operand list is generated. In discussions with Jim Grosbach, it turned out that the MC operand list really ought not to contain tied operands in the first place; instead, it ought to consist of exactly those operands that are named in the AsmString. However, getting there requires significant rework of (some) targets. This patch fixes the immediate problem, and at the same time makes one (small) step in the direction of the long-term solution, by implementing two changes: 1. Restricts the AsmMatcherEmitter handling of tied operands to apply solely to simple operands (not complex operands or sub-operand of such). This means that at least we don't get silently corrupt MC operand lists as output. However, if we do have tied sub-operands, they would now no longer be handled at all, except for: 2. If we have an operand that does not occur in the AsmString, and also isn't handled as tied operand, simply emit a dummy MC operand (constant 0). This works as long as target code never attempts to access MC operands that do no not occur in the AsmString (and are not tied simple operands), which happens to be the case for all targets where this situation can occur (ARM and PowerPC). [ Note that this change means that many of the ARM custom converters are now superfluous, since the implement the same "hack" now performed already by common code. ] Longer term, we ought to fix targets to never access *any* MC operand that does not occur in the AsmString (including tied simple operands), and then finally completely remove all such operands from the MC operand list. Patch approved by Jim Grosbach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180677 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow targets to add custom asm operand matching logic.Jim Grosbach2013-02-06
| | | | | | | | | | 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

* Remove exception handling usage from tblgen.Joerg Sonnenberger2012-10-25
| | | | | | | | | | | | Most places can use PrintFatalError as the unwinding mechanism was not used for anything other than printing the error.
