* Remove duplicated code.Rafael Espindola2011-01-231-34/+35
| | | | llvm-svn: 124054
* Fixed version of 121434 with no new memory leaks.Rafael Espindola2010-12-101-1/+1
| | | | llvm-svn: 121471
* Revert my previous patch to make the valgrind bots happy.Rafael Espindola2010-12-101-1/+1
| | | | llvm-svn: 121461
* Initial support for the cfi directives. This is just enough to getRafael Espindola2010-12-091-1/+1
| | | | | | | | | | | f: .cfi_startproc nop .cfi_endproc assembled (on ELF). llvm-svn: 121434
* Fixed version of 118639 with an extra assert to catch similar problemsRafael Espindola2010-11-091-1/+1
| | | | | | earlier. Implicit bool -> int conversions are evil! llvm-svn: 118651
* COFF: Add IMAGE_SCN_MEM_READ to text sections.Michael J. Spencer2010-10-271-0/+1
| | | | | | | | There are currently 100 references to COFF::IMAGE_SCN in 6 files and 11 different functions. Section to attribute mapping really needs to happen in one place to avoid problems like this. llvm-svn: 117473
* Fix whitespace.Michael J. Spencer2010-10-271-15/+15
| | | | llvm-svn: 117472
* lib/CodeGen/TargetLoweringObjectFileImpl.cpp: Tweak to emit ↵NAKAMURA Takumi2010-10-191-5/+5
| | | | | | | | ".{section}${name}" instead of ".{section}$linkonce_{name}" for linkonce sections. It seems GNU ld/PECOFF relies on section names, linking with g++'s libstdc++.a would fail. llvm-svn: 116791
* Do not check that the bodies of two defs of same linkonce global are the same.Anton Korobeynikov2010-10-081-1/+1
| | | | | | | Such a check does not make any sense in presense of inlining and other compiler-dependent stuff. This should fix bunch of warnings on mingw32. llvm-svn: 116113
* Revert r114997. It was causing a failure on darwin10-selfhost.Bill Wendling2010-09-281-5/+13
| | | | llvm-svn: 115002
* Fix a FIXME. _foo.eh symbols are currently always exported so that the linkerBill Wendling2010-09-281-13/+5
| | | | | | knows about them. This is not necessary on 10.6 and later. llvm-svn: 114997
* the latest assembler that runs on powerpc 10.4 machines doesn'tChris Lattner2010-09-271-0/+14
| | | | | | | support aligned comm. Detect when compiling for 10.4 and don't emit an alignment for comm. THis will hopefully fix PR8198. llvm-svn: 114817
* two changes:Chris Lattner2010-08-301-5/+0
| | | | | | | | | | | | | 1) nuke ConstDataCoalSection, which is dead. 2) revise my previous patch for rdar://8018335, which was completely wrong. Specifically, it doesn't make sense to mark __TEXT,__const_coal as PURE_INSTRUCTIONS, because it is for readonly data. templates (it turns out) go to const_coal_nt. The real fix for rdar://8018335 was to give ConstTextCoalSection a section kind of ReadOnly instead of Text. llvm-svn: 112496
* fix the definitions of ConstTextCoalSection/ConstDataCoalSectionChris Lattner2010-07-151-2/+3
| | | | | | | | | | | to keep "Text" in sync with the "pure instructions" section attribute. Lack of this attribute was preventing the assembler from emitting multibyte noops instructions for templates (and inlines, and other coalesced stuff) and was causing the assembler to mismatch .o files. This fixes rdar://8018335 llvm-svn: 108461
* Fix a major regression on COFF targets introduced by r103267: 'discardable' ↵Anton Korobeynikov2010-07-061-1/+1
| | | | | | | | section means that it is used only during the program load and can be discarded afterwards. This way *only* debug sections can be discarded, but not the opposite. Seems like the copy-and-pasto from ELF code, since there it contains the reverse flag ('alloc'). llvm-svn: 107658
* MC: Move COFF enumeration constants to llvm/Support/COFF.h, patch by MichaelDaniel Dunbar2010-07-011-55/+55
| | | | | | Spencer! llvm-svn: 107418
* Revert r107205 and r107207.Bill Wendling2010-06-291-4/+3
| | | | llvm-svn: 107215
* Introducing the "linker_weak" linkage type. This will be used for Objective-CBill Wendling2010-06-291-3/+4
| | | | | | | | | | | | | | | | | | | metadata types which should be marked as "weak", but which the linker will remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is defined like this: .globl l_objc_msgSend_fixup_alloc .weak_definition l_objc_msgSend_fixup_alloc .section __DATA, __objc_msgrefs, coalesced .align 3 l_objc_msgSend_fixup_alloc: .quad _objc_msgSend_fixup .quad L_OBJC_METH_VAR_NAME_1 This is different from the "linker_private" linkage type, because it can't have the metadata defined with ".weak_definition". llvm-svn: 107205
* Add support for initialized global data for darwin tls. Update commentsEric Christopher2010-05-251-3/+2
| | | | | | and testcases accordingly. llvm-svn: 104635
* Add full bss data support for darwin tls variables.Eric Christopher2010-05-221-2/+8
| | | | llvm-svn: 104414
* More data/parsing support for tls directives. Add a few more testcasesEric Christopher2010-05-171-0/+6
| | | | | | and cleanup comments as well. llvm-svn: 103985
* Add some section and constant support for darwin TLS.Eric Christopher2010-05-171-1/+15
| | | | llvm-svn: 103974
* add COFF support for COMDAT sections, patch by Nathan Jeffords!Chris Lattner2010-05-071-4/+16
| | | | llvm-svn: 103304
* switch MCSectionCOFF from a syntactic to semantic representation,Chris Lattner2010-05-071-54/+115
| | | | | | patch by Peter Housel! llvm-svn: 103267
* add llvm codegen support for -ffunction-sections and -fdata-sections,Chris Lattner2010-04-131-2/+36
| | | | | | patch by Sylvere Teissier! llvm-svn: 101106
* delete a forwarding function.Chris Lattner2010-04-081-89/+87
| | | | llvm-svn: 100815
* move elf section uniquing to MCContext. Along the wayChris Lattner2010-04-081-19/+1
| | | | | | merge XCore's section into MCSectionELF llvm-svn: 100812
* remove the TargetLoweringObjectFileMachO::getMachoSectionChris Lattner2010-04-081-89/+102
| | | | | | api and update clients to use MCContext instead. llvm-svn: 100808
* move macho section uniquing from MCParser and TLOF to MCContext whereChris Lattner2010-04-081-32/+4
| | | | | | | the compiler and asmparser now unique to the same sections. This fixes rdar://7835021. llvm-svn: 100807
* rename llvm::llvm_report_error -> llvm::report_fatal_errorChris Lattner2010-04-071-4/+4
| | | | llvm-svn: 100709
* Rip out the 'is temporary' nonsense from the MCContext interface toChris Lattner2010-03-301-2/+2
| | | | | | | | | create symbols. It is extremely error prone and a source of a lot of the remaining integrated assembler bugs on x86-64. This fixes rdar://7807601. llvm-svn: 99902
* Now that the default for Darwin platforms is to place the LSDA into the TEXTBill Wendling2010-03-151-3/+3
| | | | | | section, remove the target-specific code that performs this. llvm-svn: 98580
* use Mang->getSymbol() more.Chris Lattner2010-03-151-35/+17
| | | | llvm-svn: 98577
* fix MCSectionELF to not leak memory, just like I did for MCSymbol.Chris Lattner2010-03-151-4/+6
| | | | | | | MCSectionMachO is already fine (yay for fixed size arrays?), MCSectionCOFF still leaks. llvm-svn: 98537
* fix a fixme in TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner2010-03-111-3/+3
| | | | | | | | | where we used ot create an MCSymbol for ".". Now emit an assembler temporary label and reference it instead of "." textually. rdar://7739457 llvm-svn: 98292
* rename getSymbolForDwarf* to getExprForDwarf* since it returnsChris Lattner2010-03-111-10/+12
| | | | | | | | | an MCExpr and not an MCSymbol. Change it to take an MCStreamer, which is currently unused. No functionality change. llvm-svn: 98278
* Add a bit along with the MCSymbols stored in the MachineModuleInfo maps thatBill Wendling2010-03-101-8/+18
| | | | | | | | indicates that an MCSymbol is external or not. (It's true if it's external.) This will be used to specify the correct information to add to non-lazy pointers. That will be explained further when this bit is used. llvm-svn: 98199
* move three lowering hooks from MAI to TLOF and make one of themChris Lattner2010-03-101-0/+8
| | | | | | | semantic instead of syntactic. This completes MCization of darwin/x86[-64]! llvm-svn: 98145
* set the temporary bit on MCSymbols correctly.Chris Lattner2010-03-101-4/+10

* Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. ThisCharles Davis2010-03-051-1/+1
| | | | | | | | | is a workaround for <rdar://problem/7672401/> (which I filed). This let's us build Wine on Darwin, and it gets the Qt build there a little bit further (so Doug says). llvm-svn: 97845
* Revert...Bill Wendling2010-03-031-3/+3
| | | | | | | --- Reverse-merging r97592 into '.': U lib/CodeGen/TargetLoweringObjectFileImpl.cpp llvm-svn: 97657
* Okay. One last attempt:Bill Wendling2010-03-021-3/+3
| | | | | | Place the LSDA into the TEXT section on Mach-O. This saves space. llvm-svn: 97592
* The TType is always absptr on Mach-O...at least for now.Bill Wendling2010-02-271-1/+1
| | | | llvm-svn: 97295
* It turned out that we failed to emit proper symbol stubs on non-x86/darwin ↵Anton Korobeynikov2010-02-211-1/+29
| | | | | | | | | 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
* Revert Anton's most recent EH patch (r96637), since it breaks a lot ofBob Wilson2010-02-191-17/+0
| | | | | | ARM and Thumb tests. llvm-svn: 96680
* Use the same encoding for EH stuff uniformly on all MachO targets.Anton Korobeynikov2010-02-191-0/+17
| | | | | | This hopefulyl should unbreak EH on PPC/Darwin. llvm-svn: 96637
* Move TLOF implementations to libCodegen to resolve layering violation.Anton Korobeynikov2010-02-151-0/+874
