2011-04-15Add 129518 back with a fix for when we are producing eh just because of ↵Rafael Espindola

2011-01-18minor change to rafael's recent patches: if something isChris Lattner
constant but requires a unique address, we can still put it in a readonly section, just not a mergable one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123711 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-27the latest assembler that runs on powerpc 10.4 machines doesn'tChris Lattner
support aligned comm. Detect when compiling for 10.4 and don't emit an alignment for comm. THis will hopefully fix PR8198. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114817 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-17fix GetOrCreateTemporarySymbol to require a name, clientsChris Lattner
should use CreateTempSymbol() if they don't care about the name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98712 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-12finally give Mangler a getSymbol method, which returns an MCSymbolChris Lattner
for a global instead of messing around with string buffers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98366 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-12make TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner

2010-03-11fix a fixme in TargetLoweringObjectFile::getExprForDwarfReferenceChris Lattner
where we used ot create an MCSymbol for ".". Now emit an assembler temporary label and reference it instead of "." textually. rdar://7739457 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98292 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-11rename getSymbolForDwarf* to getExprForDwarf* since it returnsChris Lattner
an MCExpr and not an MCSymbol. Change it to take an MCStreamer, which is currently unused. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98278 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10move three lowering hooks from MAI to TLOF and make one of themChris Lattner
semantic instead of syntactic. This completes MCization of darwin/x86[-64]! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98145 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22Simplify some uses of str(n)cmp with StringRef.Benjamin Kramer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94189 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19stop using the .lcomm pseudoop on darwin, instead, directly use theChris Lattner
.zerofill directive. Streamerize its generation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93868 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19make TLOF subclassify BSS based on linkage type into private, externalChris Lattner
and everything else (weak). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93846 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19fix a significant difference between llvm and gcc on ELF systems:Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93844 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19introduce a section kind for common linkage. Use this to slightlyChris Lattner
simplify and commonize some of the asmprinter logic for globals. This also avoids printing the MCSection for .zerofill, which broke the llvm-gcc build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93843 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Cleanup handling of .zerofill on darwin:Chris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93838 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-17Get MCSymbol out of the mangling business, and move all the logicChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93690 91177308-0d34-0410-b5e6-96231b3b80d8

obsolete Mangler interfaces. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93356 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-13add a fixme, ELF MCSection isn't quite right and weak unnamed globals are brokenChris Lattner
on linux (even though they are pointless, they shouldn't ICE). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93308 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-13change Mangler::makeNameProper to return its result in a SmallVectorChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93298 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-20Here's fun! It turns out that these filter functions can be internal. If they'reBill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82354 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18It's inefficient to have place the exception tables (which contain the LSDA)Bill Wendling
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82274 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-16Big change #1 for personality function references:Chris Lattner
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(); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81991 91177308-0d34-0410-b5e6-96231b3b80d8
