2010-09-27the latest assembler that runs on powerpc 10.4 machines doesn'tChris Lattner1-0/+1
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
2010-06-18Eliminate unnecessary uses of getZExtValue().Dan Gohman1-1/+1
llvm-svn: 106279
2010-04-07rename llvm::llvm_report_error -> llvm::report_fatal_errorChris Lattner1-1/+1
llvm-svn: 100709
2010-03-17fix GetOrCreateTemporarySymbol to require a name, clientsChris Lattner1-1/+1
should use CreateTempSymbol() if they don't care about the name. llvm-svn: 98712
2010-03-12finally give Mangler a getSymbol method, which returns an MCSymbolChris Lattner1-10/+1
for a global instead of messing around with string buffers. llvm-svn: 98366
2010-03-12make TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner1-5/+1
just make unnamed temp symbols instead of having to come up with its own names. llvm-svn: 98324
2010-03-11fix a fixme in TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner1-12/+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
2010-03-11rename getSymbolForDwarf* to getExprForDwarf* since it returnsChris Lattner1-6/+7
an MCExpr and not an MCSymbol. Change it to take an MCStreamer, which is currently unused. No functionality change. llvm-svn: 98278
2010-03-10move three lowering hooks from MAI to TLOF and make one of themChris Lattner1-0/+4
semantic instead of syntactic. This completes MCization of darwin/x86[-64]! llvm-svn: 98145
2010-03-10set the temporary bit on MCSymbols correctly.Chris Lattner1-1/+6
llvm-svn: 98124
2010-02-16Make error statement more personal.Bill Wendling1-1/+1

2010-02-15Add suffix for stubs, so we won't have name clashes with private symbols.Anton Korobeynikov1-0/+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
2010-01-22Simplify some uses of str(n)cmp with StringRef.Benjamin Kramer1-21/+21
llvm-svn: 94189
2010-01-19stop using the .lcomm pseudoop on darwin, instead, directly use theChris Lattner1-4/+12
.zerofill directive. Streamerize its generation. llvm-svn: 93868
2010-01-19make TLOF subclassify BSS based on linkage type into private, externalChris Lattner1-2/+7
and everything else (weak). llvm-svn: 93846
2010-01-19fix a significant difference between llvm and gcc on ELF systems:Chris Lattner1-2/+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
2010-01-19introduce a section kind for common linkage. Use this to slightlyChris Lattner1-2/+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
2010-01-19Cleanup handling of .zerofill on darwin:Chris Lattner1-0/+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
2010-01-17Get MCSymbol out of the mangling business, and move all the logicChris Lattner1-10/+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
2010-01-16move the mangler into libtarget from vmcore.Chris Lattner1-1/+2
llvm-svn: 93664
2010-01-16fix build failure.Chris Lattner1-1/+1
llvm-svn: 93628
2010-01-16remove a couple of actively incorrect uses of getMangledName.Chris Lattner1-1/+2
llvm-svn: 93627
2010-01-13fix ELF section mangling stuff for weak symbols to not useChris Lattner1-9/+11
obsolete Mangler interfaces. llvm-svn: 93356
2010-01-13Use the GV version of getNameWithPrefix in TargetLoweringObjectFileCOFF::Chris Lattner1-1/+1
SelectSectionForGlobal, unbreaking weak globals with no-name. llvm-svn: 93336
2010-01-13add a fixme, ELF MCSection isn't quite right and weak unnamed globals are brokenChris Lattner1-0/+4
on linux (even though they are pointless, they shouldn't ICE). llvm-svn: 93308
2010-01-13eliminate some uses of Mangler::makeNameProper.Chris Lattner1-1/+1
llvm-svn: 93305
2010-01-13change Mangler::makeNameProper to return its result in a SmallVectorChris Lattner1-11/+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
2010-01-07We need to put any kind of data with a relocation into aEric Christopher1-1/+1
not-readonly segment on darwin. llvm-svn: 92933

2009-11-19The "ReadOnlyWithRel" enum seems to apply more to what Darwin does with the EHBill Wendling1-1/+1
exception table than DataRel. llvm-svn: 89279

2009-09-20Still one more thing wrong here...Bill Wendling1-0/+5
llvm-svn: 82356
2009-09-20Here's fun! It turns out that these filter functions can be internal. If they'reBill Wendling1-6/+0
internal, they shouldn't use the indirect pointer stuff. In the case of throw_rethrow_test, it was marked as 'internal' and calculated its own offset to its contents. llvm-svn: 82354
2009-09-19Revert r82274. It's causing failures in the CINT2006 benchmarks.Bill Wendling1-0/+6
llvm-svn: 82336
2009-09-18It's inefficient to have place the exception tables (which contain the LSDA)Bill Wendling1-2/+2
into the __DATA section. At launch time, dyld has to update most of the section to fix up the type info pointers. It's better to place it into the __TEXT section and use pc-rel indirect pointer encodings. Similar to the personality routine. llvm-svn: 82274
2009-09-17pass machinemoduleinfo down into getSymbolForDwarfGlobalReference, Chris Lattner1-0/+2
currently unused. llvm-svn: 82157
2009-09-16Big change #1 for personality function references:Chris Lattner1-0/+39
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

2009-08-15the .eh_frame sections we generate need to be writable (whichChris Lattner1-1/+2
is why they are datarel). This should fix PR4724, and is fallout from r78890. llvm-svn: 79111
