* [DebugInfo] Allow getDebugThreadLocalSymbol to return MCExprUlrich Weigand2013-07-021-1/+1
| | | | | | | | | | | This allows getDebugThreadLocalSymbol to return a generic MCExpr instead of just a MCSymbolRefExpr. This is in preparation for supporting debug info for TLS variables on PowerPC, where we need to describe the variable location using a more complex expression than just MCSymbolRefExpr. llvm-svn: 185460
* PR16493: DebugInfo with TLS on PPC crashing due to invalid relocationDavid Blaikie2013-07-011-0/+6
| | | | | | | | Restrict the current TLS support to X86 ELF for now. Test that we don't produce it on PPC & we can flesh that test case out with the right thing once someone implements it. llvm-svn: 185389

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-031-1/+1
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] llvm-svn: 169131
* Use TARGET2 relocation for TType references on ARM.Anton Korobeynikov2012-11-141-4/+4
| | | | | | | | Do some cleanup of the code while here. Inspired by patch by Logan Chien! llvm-svn: 167904

* Move the support for using .init_array from ARM to the genericRafael Espindola2012-06-191-0/+9
| | | | | | | | | | TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM, on X86 it is not easy to find out if .init_array should be used or not, so the decision is made via TargetOptions and defaults to off. Add a command line option to llc that enables it. llvm-svn: 158692

* Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.Evan Cheng2011-07-201-76/+0
| | | | | | | There is still a bit more refactoring left to do in Targets. But we are now very close to fixing all the layering issues in MC. llvm-svn: 135611
* Remove an unused variable from this function introduced in r130637,Chandler Carruth2011-05-011-1/+0

* GCC uses a different encoding of pointers in the FDE when usingRafael Espindola2011-05-011-3/+10

* Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, andRafael Espindola2011-04-271-0/+6
| | | | | | | | | | | | | | | | | | give it a bit more responsibility. Also implement it for MachO. If hacked to use cfi, 32 bit MachO will produce .cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr and 64 bit will produce .cfi_presonality ___gxx_personality_v0 The general idea is that .cfi_personality gets passed the final symbol. It is up to codegen to produce it if using indirect representation (like 32 bit MachO), but it is up to MC to decide which relocations to create. llvm-svn: 130341
* Compute the size of the FDE encoding instead of hard coding it. UpdateRafael Espindola2011-04-221-10/+1

* MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.Daniel Dunbar2010-03-151-2/+2
| | | | | | | - Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue. - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol. llvm-svn: 98592
* Now that the default for Darwin platforms is to place the LSDA into the TEXTBill Wendling2010-03-151-13/+0

* Place the LSDA into the TEXT section for x86 Darwin. If the global it's pointingBill Wendling2010-03-151-0/+14
| | | | | | | | | | | to is local to the translation unit, we need to place fill the value of that symbol into the non-lazy pointer. This should conclude all Darwin changes for placing the LSDA into the TEXT section. There is some cleanup to do. I.e., there's no longer a special need for target-specific code here. But that can come later. llvm-svn: 98564

* It turned out that we failed to emit proper symbol stubs on non-x86/darwin ↵Anton Korobeynikov2010-02-211-64/+0
| | | | | | | | | for ages (we emitted a reference to a stub, but no stub was emitted). The code inside x86-32/macho target objfile lowering should actually be the generic one - move it there. This (I really, really hope) should fix EH issues on ppc/darwin and arm/darwin. llvm-svn: 96755

| | | | | | | | | | | | | | | | | | | | | | getSymbolForDwarfGlobalReference is smart enough to know that it needs to register the stub it references with MachineModuleInfoMachO, so that it gets emitted at the end of the file. Move stub emission from X86ATTAsmPrinter::doFinalization to the new X86ATTAsmPrinter::EmitEndOfAsmFile asmprinter hook. The important thing here is that EmitEndOfAsmFile is called *after* the ehframes are emitted, so we get all the stubs. This allows us to remove a gross hack from the asmprinter where it would "just know" that it needed to output stubs for personality functions. Now this is all driven from a consistent interface. The testcase change is just reordering the expected output now that the stubs come out after the ehframe instead of before. This also unblocks other changes that Bill wants to make. llvm-svn: 82269

* Big change #1 for personality function references:Chris Lattner2009-09-161-0/+33
Eliminate the PersonalityPrefix/Suffix & NeedsIndirectEncoding fields from MAI: they aren't part of the asm syntax, they are related to the structure of the object file. To replace their functionality, add a new TLOF::getSymbolForDwarfGlobalReference method which asks targets to decide how to reference a global from EH in a pc-relative way. The default implementation just returns the symbol. The default darwin implementation references the symbol through an indirect $non_lazy_ptr stub. The bizarro x86-64 darwin specialization handles the weird "foo@GOTPCREL+4" hack. DwarfException.cpp now uses this to emit the reference to the symbol in the right way, and this also eliminates another horrible hack from DwarfException.cpp: - if (strcmp(MAI->getPersonalitySuffix(), "+4@GOTPCREL")) - O << "-" << MAI->getPCSymbol(); llvm-svn: 81991
