* Fix coding style issues pointed by Bill.Bruno Cardoso Lopes2009-07-161-18/+19
| | | | llvm-svn: 75898
* use std::vector instead of std::list for both Section and Symbol lists becauseBruno Cardoso Lopes2009-07-151-97/+99
| | | | | | we care more about random access than insertion/deletion of elements. llvm-svn: 75828
* Reapply my previous asmprinter changes now with more testing and two Chris Lattner2009-07-141-1/+1
| | | | | | | | | | | | | | | | | | | | 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 Edwin2009-07-141-5/+5
| | | | | | | | | 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

* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-5/+6
| | | | | | | | | 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

* Move ELFCodeEmiter stuff to new filesBruno Cardoso Lopes2009-06-031-140/+2
| | | | llvm-svn: 72785
* 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
* Introduce new linkage types linkonce_odr, weak_odr, common_odrDuncan Sands2009-03-071-2/+4
| | | | | | | | | | | | | | | | | | | | | 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
* Add support to the JIT for true non-lazy operation. When a call to a functionNate Begeman2009-02-181-0/+4
| | | | | | | | | | | | | | | | | | | | that has not been JIT'd yet, the callee is put on a list of pending functions to JIT. The call is directed through a stub, which is updated with the address of the function after it has been JIT'd. A new interface for allocating and updating empty stubs is provided. Add support for removing the ModuleProvider the JIT was created with, which would otherwise invalidate the JIT's PassManager, which is initialized with the ModuleProvider's Module. Add support under a new ExecutionEngine flag for emitting the infomration necessary to update Function and GlobalVariable stubs after JITing them, by recording the address of the stub and the name of the GlobalValue. This allows code to be copied from one address space to another, where libraries may live at different virtual addresses, and have the stubs updated with their new correct target addresses. llvm-svn: 64906
* Add the private linkage.Rafael Espindola2009-01-151-1/+4
| | | | llvm-svn: 62279
* Rename getABITypeSize to getTypePaddedSize, asDuncan Sands2009-01-121-1/+1
| | | | | | suggested by Chris. llvm-svn: 62099
* elf writer really wants the size of the global, not the size Chris Lattner2009-01-041-3/+3

* The llvm::ELFWriter::EmitGlobal() method is calling theBill Wendling2009-01-041-0/+1
| | | | | | | | | | llvm::PATypeHolder::get() method when LLVM is self-hosted in Release mode. Before the parser changed, there was a definition of llvm::PAHolder::get() in llvmAsmParser.y. This was probably a bug that no-one noticed. Explicitly #include the Type.h file as a temporary fix for now. llvm-svn: 61620
* Fix MachineCodeEmitter to use uintptr_t instead of intptr_t. This avoids ↵Evan Cheng2008-12-101-4/+4
| | | | | | some overflow issues. Patch by Thomas Jablin. llvm-svn: 60828
* Rename startFunctionStub to startGVStub since it's also used for GV non-lazy ↵Evan Cheng2008-11-081-3/+3

* Tidy up several unbeseeming casts from pointer to intptr_t.Dan Gohman2008-09-041-1/+1

* Add CommonLinkage; currently tentative definitionsDale Johannesen2008-05-141-2/+3
| | | | | | | | | | are represented as "weak", but there are subtle differences in some cases on Darwin, so we need both. The intent is that "common" will behave identically to "weak" unless somebody changes their target to do something else. No functional change as yet. llvm-svn: 51118
* Fix a bug in the ELF writer that caused it to produce malformedDan Gohman2008-05-051-1/+1
| | | | | | ELF headers. The ELF writer still isn't generally usable though. llvm-svn: 50652
* Correlate stubs with functions in JIT: when emitting a stub, the JIT tells ↵Nicolas Geoffray2008-04-161-2/+3
| | | | | | | | the memory manager which function the stub will resolve. llvm-svn: 49814
* Use PassManagerBase instead of FunctionPassManager for functionsDan Gohman2008-03-111-2/+2
| | | | | | | | that merely add passes. This allows them to be used with either FunctionPassManager or PassManager, or even with a custom new kind of pass manager. llvm-svn: 48256
* Enable exception handling int JITNicolas Geoffray2008-02-131-0/+15
| | | | llvm-svn: 47079
* Use getPreferredAlignmentLog or getPreferredAlignmentDuncan Sands2008-01-291-1/+1
| | | | | | | to get the alignment of global variables, rather than using hand-made versions. llvm-svn: 46495
* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2

* Add explicit keywords, and fix a minor typo that they uncovered.Dan Gohman2007-12-141-1/+1

* Eliminate the remaining uses of getTypeSize. ThisDuncan Sands2007-11-051-1/+1
| | | | | | | | | | | | | | should only effect x86 when using long double. Now 12/16 bytes are output for long double globals (the exact amount depends on the alignment). This brings globals in line with the rest of LLVM: the space reserved for an object is now always the ABI size. One tricky point is that only 10 bytes should be output for long double if it is a field in a packed struct, which is the reason for the additional argument to EmitGlobalConstant. llvm-svn: 43688
* Drop 'const'Devang Patel2007-05-031-1/+1
| | | | llvm-svn: 36662
* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-1/+1
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
* Do not use typeinfo to identify pass in pass manager.Devang Patel2007-05-011-1/+3
