* Remove unnecessary argument.Rafael Espindola2011-04-271-1/+1
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130343 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130341 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.

| | | | | | | | | | 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
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93838 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93690 91177308-0d34-0410-b5e6-96231b3b80d8
