2011-07-06Remove the AsmWriterEmitter (unused) feature that rely on TargetSubtargetInfo.Evan Cheng
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134457 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-29Change AsmName's type from StringRef to std::string. AsmName was pointing to ↵Francois Pichet
a temporary string object that was destroyed. This is undefined behavior and MSVC didn't like it. This fixes over 300+ failing tests on MSVC. Credit for this fix goes to chapuni. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134064 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-27Add support for alternative register names, useful for instructions whose ↵Owen Anderson
operands are logically equivalent to existing registers, but happen to be printed specially. For example, an instruciton that prints d0[0] instead of s0. Patch by Jim Grosbach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133940 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-21Consolidate some TableGen diagnostic helper functions.Jim Grosbach
TableGen had diagnostic printers sprinkled about in a few places. Pull them together into a single location in Error.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133568 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-18Store CodeGenRegisters as pointers so they won't be reallocated.Jakob Stoklund Olesen
Reuse the CodeGenRegBank DenseMap in a few places that would build their own or use linear search. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133333 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-15Give CodeGenRegisterClass a real sorted member set.Jakob Stoklund Olesen
Make the Elements vector private and expose an ArrayRef through getOrder() instead. getOrder will eventually provide multiple user-specified allocation orders. Use the sorted member set for member and subclass tests. Clean up a lot of ad hoc searches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133040 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-15Improve the heuristic to emit the alias if the number of hard-coded registersBill Wendling
are also greater than the alias. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133038 91177308-0d34-0410-b5e6-96231b3b80d8
2011-06-14Heuristic: If the number of operands in the alias are more than the number ofBill Wendling
operands in the aliasee, don't print the alias. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132963 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-23Use a more efficient data structure for the "operand map". The number ofBill Wendling
operands to an instruction aren't great, so an iterative search is fairly quick and doesn't have the overhead of std::map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@131886 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-18Invert the meaning of printAliasInstr's return value. It now returnsEric Christopher
true on success and false on failure. Update callers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129722 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-13Add an option to not print the alias of an instruction. It defaults to "printBill Wendling
the alias". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129485 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-08Only emit the AvailableFeatures variable if it's used.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129124 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-07Replace the old algorithm that emitted the "print the alias for an instruction"Bill Wendling
with the newer, cleaner model. It uses the IAPrinter class to hold the information that is needed to match an instruction with its alias. This also takes into account the available features of the platform. There is one bit of ugliness. The way the logic determines if a pattern is unique is O(N**2), which is gross. But in reality, the number of items it's checking against isn't large. So while it's N**2, it shouldn't be a massive time sink. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129110 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-21Call static functions so that they aren't left unused.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128020 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-21A WIP commit of the InstAlias printing cleanup. This code will soon replace theBill Wendling
code below it. Even though it looks very similar, it will match more precisely and geneate better functions in the long run. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127991 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-21Add the IAPrinter class.Bill Wendling
This is a helper class that will make it easier to say which InstAliases can be printed and which cannot (because of ambiguity). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127990 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-21* Add classes that support the "feature" information.Bill Wendling
* Move the code that emits the reg in reg class matching into its own function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127988 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-26A new TableGen feature! (Not turned on just yet.)Bill Wendling
InstAlias<{alias}, {aliasee}>; The InstAlias instruction should be able to go from the MCInst to the {alias}. All of the information is there to match the MCInst with the {aliasee}. From there, it's a simple matter to emit the {alias}, with the correct operands from the {aliasee}. The code this patch generates can be used by the InstPrinter to automatically print out the alias without having to write special C++ code to handle the situation. This is a WIP, and therefore are several limitations. For instance, it cannot handle AsmOperands at the moment. It also doesn't know what to do when two {alias}es match the same {aliasee}. (Currently, it just ignores those two cases and allows the printInstruction method to handle them.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126538 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-13eliminate the Records global variable, patch by Garrison Venn!Chris Lattner

2010-09-30Let a target specify whether it wants an assembly printer to be the MC versionJim Grosbach
or not. TableGen needs to generate the printInstruction() function as taking an MCInstr* or a MachineInstr*, depending. Default to the old non-MC version so that everything not yet using MC continues to just work without fidding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115126 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-04change a ton of code to not implicitly use the "O" raw_ostreamChris Lattner

2010-02-09Fixed some indentation in the AsmWriterInstSean Callanan
implementation. Also changed the constructor so that it does not require a Record, making it usable by the EDEmitter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95715 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-09Per PR 6219, factored AsmWriterInst and AsmWriterOperandSean Callanan
out of the AsmWriterEmitter. This patch does the physical code movement, but leaves the implementation unchanged. I'll make any changes necessary to generalize the code in a separate patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95697 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-28Introduce the TargetInstrInfo::KILL machine instruction and get rid of theJakob Stoklund Olesen
unused DECLARE instruction. KILL is not yet used anywhere, it will replace TargetInstrInfo::IMPLICIT_DEF in the places where IMPLICIT_DEF is just used to alter liveness of physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83006 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-11PHI nodes can never reach the asmprinter, assert and die instead of printingChris Lattner
out an illegal "PHINODE" instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81495 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-09remove DebugLoc from MCInst and eliminate "Comment printing" fromChris Lattner
the MCInst path of the asmprinter. Instead, pull comment printing out of the autogenerated asmprinter into each target that uses the autogenerated asmprinter. This causes code duplication into each target, but in a way that will be easier to clean up later when more asmprinter stuff is commonized into the base AsmPrinter class. This also fixes an xcore strangeness where it inserted two tabs before every instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81396 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-09Fix a subtle bug in "return;" generation which caused us to missChris Lattner
a return in one case. Instead of sprinking return handling code throughout the asmprinter generator, just treat it like any other normal statement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81395 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-09hoist the call to processDebugLoc out of the generatedChris Lattner
asm printer into the "printInstruction" routine. This fixes a problem where the experimental asmprinter would drop debug labels in some cases, and fixes issues on ppc/xcore where pseudo instructions like "mr" didn't get debug locs properly. It is annoying that this moves the call from one place into each target, but a future set of more invasive refactorings will fix that problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81377 91177308-0d34-0410-b5e6-96231b3b80d8
