* Register Target's TargetMachine and AsmPrinter in the new registry.Daniel Dunbar2009-07-152-2/+8
| | | | | | | - This abuses TargetMachineRegistry's constructor for now, this will get cleaned up in time. llvm-svn: 75762
* Add TargetInfo libraries for all targets.Daniel Dunbar2009-07-154-1/+83
| | | | | | | | - Intended to match current TargetMachine implementations. - No facilities for linking these in yet. llvm-svn: 75751
* Have asm printers use formatted_raw_ostream directly to avoid aDavid Greene2009-07-144-8/+9
| | | | | | dynamic_cast<>. llvm-svn: 75670
* Reapply my previous asmprinter changes now with more testing and two Chris Lattner2009-07-141-5/+2
| | | | | | | | | | | | | | | | | | | | additional bug fixes: 1. The bug that everyone hit was a problem in the asmprinter where it would remove $stub but keep the L prefix on a name when emitting the indirect symbol. This is easy to fix by keeping the name of the stub and the name of the symbol in a StringMap instead of just keeping a StringSet and trying to reconstruct it late. 2. There was a problem printing the personality function. The current logic to print out the personality function from the DWARF information is a bit of a cesspool right now that duplicates a bunch of other logic in the asm printer. The short version of it is that it depends on emitting both the L and _ prefix for symbols (at least on darwin) and until I can untangle it, it is best to switch the mangler back to emitting both prefixes. llvm-svn: 75646
* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-146-26/+26
| | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). llvm-svn: 75640
* Revert r75615, which depended on 75610.Daniel Dunbar2009-07-141-2/+5

* Rename getValueName -> getMangledName.Chris Lattner2009-07-141-5/+2
| | | | llvm-svn: 75615
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-115-21/+26
| | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. llvm-svn: 75379
* Thread LLVMContext through MVT and related parts of SDISel.Owen Anderson2009-07-091-2/+3
| | | | llvm-svn: 75153
* Implement changes from Chris's feedback.Torok Edwin2009-07-082-4/+6
| | | | | | Finish converting lib/Target. llvm-svn: 75043
* Convert more abort() calls to llvm_report_error().Torok Edwin2009-07-081-8/+6
| | | | | | Also remove trailing semicolon. llvm-svn: 75027

* Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves ↵Evan Cheng2009-07-011-2/+5
| | | | | | the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details. llvm-svn: 74580
* Remove unused AsmPrinter OptLevel argument, and propogate.Daniel Dunbar2009-07-014-8/+4
| | | | | | | - This more or less amounts to a revert of r65379. I'm curious to know what happened that caused this variable to become unused. llvm-svn: 74579
* Add an "alignment" field to the MachineFunction object. It makes more sense toBill Wendling2009-06-303-1/+9
| | | | | | | | | | have the alignment be calculated up front, and have the back-ends obey whatever alignment is decided upon. This allows for future work that would allow for precise no-op placement and the like. llvm-svn: 74564

* Provide InitializeAllTargets and InitializeNativeTarget functions in theBob Wilson2009-06-232-9/+4
| | | | | | | | C bindings. Change all the backend "Initialize" functions to have C linkage. Change the "llvm/Config/Targets.def" header to use C-style comments to avoid compile warnings. llvm-svn: 74026
* Eliminate object-relinking support from CMake. Fixes PR 4429 andDouglas Gregor2009-06-231-5/+1
| | | | | | | cleans up the CMake-based build system a bit. Started by a patch from Xerxes Rånby. llvm-svn: 73969
* fix the sparc codegen to not depend on the sparc asmprinter.Chris Lattner2009-06-193-11/+29
| | | | llvm-svn: 73767
* Introduce new headers whose inclusion forces linking andDouglas Gregor2009-06-162-0/+11
| | | | | | | | | initialization of all targets (InitializeAllTargets.h) or assembler printers (InitializeAllAsmPrinters.h). This is a step toward the elimination of relinked object files, so that we can build normal archives. llvm-svn: 73543
* Propagate CPU string out of SubtargetFeaturesAnton Korobeynikov2009-05-231-2/+3
| | | | llvm-svn: 72335
* Change MachineInstrBuilder::addReg() to take a flag instead of a list ofBill Wendling2009-05-131-6/+6
| | | | | | | | | | | | booleans. This gives a better indication of what the "addReg()" is doing. Remembering what all of those booleans mean isn't easy, especially if you aren't spending all of your time in that code. I took Jakob's suggestion and made it illegal to pass in "true" for the flag. This should hopefully prevent any unintended misuse of this (by reverting to the old way of using addReg()). llvm-svn: 71722
* Rename PaddedSize to AllocSize, in the hope that thisDuncan Sands2009-05-091-1/+1
| | | | | | | will make it more obvious what it represents, and stop it being confused with the StoreSize. llvm-svn: 71349
* Instead of passing in an unsigned value for the optimization level, use an enum,Bill Wendling2009-04-294-10/+14
| | | | | | | which better identifies what the optimization is doing. And is more flexible for future uses. llvm-svn: 70440
* Second attempt:Bill Wendling2009-04-294-14/+18
| | | | | | | | | | | | Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to use the old behavior, the flag is -O0. This change allows for finer-grained control over which optimizations are run at different -O levels. Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'll change the JIT with a follow-up patch. llvm-svn: 70343

Most of this work was pretty mechanical. The majority of the fixes came from verifying that a "fast" variable wasn't used anymore. The JIT still uses a "Fast" flag. I'm not 100% sure if it's necessary to change it there... llvm-svn: 70270
* CodeGen still defaults to non-verbose asm, but llc now overrides it and ↵Evan Cheng2009-03-254-9/+9
| | | | | | default to verbose. llvm-svn: 67668
* It makes no sense to have a ODR version of commonDuncan Sands2009-03-111-2/+1
| | | | | | linkage, so remove it. llvm-svn: 66690
* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-4/+7
| | | | | | | | | | | | | | | | | | | | | and extern_weak_odr. These are the same as the non-odr versions, except that they indicate that the global will only be overridden by an *equivalent* global. In C, a function with weak linkage can be overridden by a function which behaves completely differently. This means that IP passes have to skip weak functions, since any deductions made from the function definition might be wrong, since the definition could be replaced by something completely different at link time. This is not allowed in C++, thanks to the ODR (One-Definition-Rule): if a function is replaced by another at link-time, then the new function must be the same as the original function. If a language knows that a function or other global can only be overridden by an equivalent global, it can give it the weak_odr linkage type, and the optimizers will understand that it is alright to make deductions based on the function body. The code generators on the other hand map weak and weak_odr linkage to the same thing. llvm-svn: 66339
* Overhaul my earlier submission due to feedback. It's a large patch, but most ofBill Wendling2009-02-243-9/+13
| | | | | | | | | | | | them are generic changes. - Use the "fast" flag that's already being passed into the asm printers instead of shoving it into the DwarfWriter. - Instead of calling "MI->getParent()->getParent()" for every MI, set the machine function when calling "runOnMachineFunction" in the asm printers. llvm-svn: 65379

| | | | | | ScheduleDAG's TLI member to use const. llvm-svn: 64018
* Get rid of the last non-DebugLoc versions of getNode!Dale Johannesen2009-02-071-4/+6
| | | | | | | | | | | | Many targets build placeholder nodes for special operands, e.g. GlobalBaseReg on X86 and PPC for the PIC base. There's no sensible way to associate debug info with these. I've left them built with getNode calls with explicit DebugLoc::getUnknownLoc operands. I'm not too happy about this but don't see a good improvement; I considered adding a getPseudoOperand or something, but it seems to me that'll just make it harder to read. llvm-svn: 63992
* Remove more non-DebugLoc getNode variants. UseDale Johannesen2009-02-061-3/+3
| | | | | | | | getCALLSEQ_{END,START} to permit passing no DebugLoc there. UNDEF doesn't logically have DebugLoc; add getUNDEF to encapsulate this. llvm-svn: 63978
