* Fix up TargetLoweringObjectFile ctors to properly initialize fields.Evan Cheng2011-07-131-26/+26
| | | | llvm-svn: 135068
* Use the presence of the __compact_unwind section to indicate that a targetBill Wendling2011-06-231-1/+0
| | | | | | supports compact unwind info instead of having a separate flag indicating this. llvm-svn: 133685
* Add a flag that indicates whether a target supports compact unwind info or not.Bill Wendling2011-06-221-0/+1
| | | | llvm-svn: 133662
* Add a __LD,__compact_unwind section.Bill Wendling2011-06-221-0/+1
| | | | | | | | If the linker supports it, this will hold the CIE and FDE information in a compact format. The implementation of the compact unwinding emission is coming soon. llvm-svn: 133658
* Fix a FIXME by making GlobalVariable::getInitializer() return aJay Foad2011-06-191-2/+2

* Remove a flag that would set the ".eh" symbol as .globl. MachO was the only oneBill Wendling2011-05-051-1/+0
| | | | | | | | who used this flag, and it now emits CFI and doesn't emit this anymore. All other targets left this flag "false". <rdar://problem/8486371> llvm-svn: 130918
* GCC uses a different encoding of pointers in the FDE when usingRafael Espindola2011-05-011-1/+1

* Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, andRafael Espindola2011-04-271-5/+4
| | | | | | | | | | | | | | | | | | 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

| | | | | | Add support for SHT_X86_64_UNWIND. llvm-svn: 124059

* Only put unnamed_addr constants in mergeable sections. Fixes PR8297.Rafael Espindola2011-01-161-1/+1

* the latest assembler that runs on powerpc 10.4 machines doesn'tChris Lattner2010-09-271-0/+1

* rename llvm::llvm_report_error -> llvm::report_fatal_errorChris Lattner2010-04-071-1/+1
| | | | llvm-svn: 100709
* fix GetOrCreateTemporarySymbol to require a name, clientsChris Lattner2010-03-171-1/+1
| | | | | | | should use CreateTempSymbol() if they don't care about the name. llvm-svn: 98712
* finally give Mangler a getSymbol method, which returns an MCSymbolChris Lattner2010-03-121-10/+1
| | | | | | for a global instead of messing around with string buffers. llvm-svn: 98366
* make TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner2010-03-121-5/+1
| | | | | | | just make unnamed temp symbols instead of having to come up with its own names. llvm-svn: 98324
* fix a fixme in TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner2010-03-111-12/+18
| | | | | | | | | 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 Lattner2010-03-111-6/+7
| | | | | | | | | an MCExpr and not an MCSymbol. Change it to take an MCStreamer, which is currently unused. No functionality change. llvm-svn: 98278
* move three lowering hooks from MAI to TLOF and make one of themChris Lattner2010-03-101-0/+4
| | | | | | | semantic instead of syntactic. This completes MCization of darwin/x86[-64]! llvm-svn: 98145
* set the temporary bit on MCSymbols correctly.Chris Lattner2010-03-101-1/+6
| | | | llvm-svn: 98124
* Make error statement more personal.Bill Wendling2010-02-161-1/+1

| | | | | | Personality / FDE / LSDA / TType encoding depending on target / options (e.g. code model / relocation model) - MCIzation of Dwarf EH printer to use encoding information - Stub generation for ELF target (needed for indirect references) - Some other small changes here and there llvm-svn: 96285
* Simplify some uses of str(n)cmp with StringRef.Benjamin Kramer2010-01-221-21/+21

* stop using the .lcomm pseudoop on darwin, instead, directly use theChris Lattner2010-01-191-4/+12
| | | | | | .zerofill directive. Streamerize its generation. llvm-svn: 93868
* make TLOF subclassify BSS based on linkage type into private, externalChris Lattner2010-01-191-2/+7
| | | | | | and everything else (weak). llvm-svn: 93846
* fix a significant difference between llvm and gcc on ELF systems:Chris Lattner2010-01-191-2/+4
| | | | | | | | GCC would put weak zero initialized mutable data in the .bss section, we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits' section. Fixing this will allow simplifications next up. llvm-svn: 93844
* introduce a section kind for common linkage. Use this to slightlyChris Lattner2010-01-191-2/+6
| | | | | | | | | simplify and commonize some of the asmprinter logic for globals. This also avoids printing the MCSection for .zerofill, which broke the llvm-gcc build. llvm-svn: 93843
* Cleanup handling of .zerofill on darwin:Chris Lattner2010-01-191-0/+8
| | | | | | | | | | | | | 1. TargetLoweringObjectFileMachO should decide if something goes in zerofill instead of having every target do it. 2. TargetLoweringObjectFileMachO should assign said symbols to the right MCSection, the asmprinters should just emit to the right section. 3. Since all zerofill stuff goes through mcstreamer anymore, MAI can have a bool "haszerofill" instead of having the textual directive to emit. llvm-svn: 93838
* Get MCSymbol out of the mangling business, and move all the logicChris Lattner2010-01-171-10/+3
| | | | | | | | | | | to Mangler. Now MCSymbol just decides whether to slap quotes around a symbol when printing it. This also fixes some weirdness where two MCSymbols could be created for the same symbol, if one needed to be mangled and got mangled to the other one. llvm-svn: 93690
* move the mangler into libtarget from vmcore.Chris Lattner2010-01-161-1/+2

* change Mangler::makeNameProper to return its result in a SmallVectorChris Lattner2010-01-131-11/+13
| | | | | | | | | | | | instead of returning it in an std::string. Based on this change: 1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef 2. Change a bunch of targets to call makeNameProper with a smallstring, making several of them *much* more efficient. 3. Rewrite Mangler::makeNameProper to not build names and then prepend prefixes, not use temporary std::strings, and to avoid other crimes. llvm-svn: 93298
