2010-08-31This is the second of three patches to implement support for the .loc directiveKevin Enderby
and output the dwarf line number tables. This takes the current loc info after an instruction is assembled and saves the needed info into an object that has vector and for each section. These objects will be used for the final patch to build and emit the encoded dwarf line number tables. Again for now this is only in the Mach-O streamer but at some point will move to a more generic place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112668 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24First bit of support for the dwarf .loc directive. This patch updates theKevin Enderby
needed parsing for the .loc directive and saves the current info from that into the context. The next patch will take the current loc info after an instruction is assembled and save that info into a vector for each section for use to build the line number tables. The patch after that will encode the info from those vectors into the output file as the dwarf line tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111956 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-09Next bit of support for the dwarf .file directive. This patch takes theKevin Enderby
previously collected info from the .file directives and outputs the encoded bytes for it. For now this is only in the Mach-O streamer but at some point will move to a more generic place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@110617 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-28Added first bit of support for the dwarf .file directive. This patch collectsKevin Enderby
the info from the .file directive and makes file and directory tables that will eventually be put out as part of the dwarf info in the output file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109651 91177308-0d34-0410-b5e6-96231b3b80d8

patch by Peter Housel! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103267 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08move elf section uniquing to MCContext. Along the wayChris Lattner
merge XCore's section into MCSectionELF git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100812 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-08move macho section uniquing from MCParser and TLOF to MCContext whereChris Lattner
the compiler and asmparser now unique to the same sections. This fixes rdar://7835021. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100807 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Rip out the 'is temporary' nonsense from the MCContext interface toChris Lattner
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99902 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
2010-03-15fix a memory leak yjasskin pointed out: MCSymbol is bump pointerChris Lattner
allocated and thus not freed. This is cool except that it contains and std::string so the string data didn't get freed. In any case there is no reason to redundantly store the string data in the MCSymbol anyway, just make the MCSymbol ref the string data in the MCContext StringMap. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98536 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-14add a new CreateTempSymbol method, the use case forChris Lattner
CreateTempSymbol vs GetOrCreateTemporarySymbol are completely different. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98486 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-16MC: Switch MCContext value table to storing MCExprs.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84228 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-26llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.Daniel Dunbar
- I moved section creation back into AsmParser. I think policy decisions like this should be pushed higher, not lower, when possible (in addition the assembler has flags which change this behavior, for example). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80162 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-13sink uniquing of sections out of MCContext into the ELF and PECOFF TLOF ↵Chris Lattner
implementations. MCContext no longer maintains a string -> section map. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78874 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-13add some comments: MCContext owns the MCSections, but it bump pointer allocatesChris Lattner
them, so it doesn't have to explicitly free them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78870 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31split MCSection stuff out to its own .cpp file, add a newChris Lattner
MCSectionWithKind subclass of MCSection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77684 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-31create sections with MCSection::Create instead of Context->getOrCreateSection.Chris Lattner
This is needed to allow polymorphic sections. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77680 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-24We decided to not worry about Atoms for now, it should be straightforward toDaniel Dunbar
reintroduce them later. Also, don't require MCSection* when creating a symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74081 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-24add trivial support for passing label definitions through the MCStreamer.Chris Lattner
This is suboptimal in several aspects, see the commented out assertion. I need to talk to Daniel about this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74057 91177308-0d34-0410-b5e6-96231b3b80d8
