* MC assembly parser handling for trailing comma in macro instantiation.Jim Grosbach2012-04-161-5/+5
| | | | | | | | | A trailing comma means no argument at all (i.e., as if the comma were not present), not an empty argument to the invokee. rdar://11252521 llvm-svn: 154863

* Use the correct section types on Solaris for unwind data on both x86 and x86-64.David Chisnall2012-04-101-3/+8
| | | | | | Patch by Dmitri Shubin! llvm-svn: 154391
* Output UTF-8-encoded characters as identifier characters into assemblyAlexis Hunt2012-04-071-0/+1
| | | | | | | | | | | | | | by default. This is a behaviour configurable in the MCAsmInfo. I've decided to turn it on by default in (possibly optimistic) hopes that most assemblers are reasonably sane. If this proves a problem, switching to default seems reasonable. I'm not sure if this is the opportune place to test, but it seemed good to make sure it was tested somewhere. llvm-svn: 154235
* Fixed two leaks in the MC disassembler. The MCSean Callanan2012-04-062-1/+13
| | | | | | | | | | | | | | | disassembler requires a MCSubtargetInfo and a MCInstrInfo to exist in order to initialize the instruction printer and disassembler; however, although the printer and disassembler keep references to these objects they do not own them. Previously, the MCSubtargetInfo and MCInstrInfo objects were just leaked. I have extended LLVMDisasmContext to own these objects and delete them when it is destroyed. llvm-svn: 154192

* MC asm parser macro argument count was wrong when empty.Jim Grosbach2012-03-171-0/+5
| | | | | | | | evaluated to '1' when the argument list was empty (should be '0'). rdar://11057257 llvm-svn: 152967
* Implement relocation-overflow behavior for PE/COFF.Michael J. Spencer2012-03-151-2/+29
| | | | | | | | | This needs a test, but it will take some time to figure out the best way to get an input that will produce > 2^16 relocs. Patch by Graydon Hoare! llvm-svn: 152787
* Make MCRegisterInfo available to the the MCInstPrinter.Jim Grosbach2012-03-052-2/+3
| | | | | | | Used to allow context sensitive printing of super-register or sub-register references. llvm-svn: 152043
* Correctly initialize LineSectionSymbol. Thanks to Duncan Sands for noticing it.Rafael Espindola2012-03-032-2/+2

* On ELF, create relocations to the abbreviation and line sections when producingRafael Espindola2012-02-283-10/+34
| | | | | | | | | | debug info for assembly files. We were already doing the right thing when producing debug info for C/C++. ELF linkers don't know dwarf, so they depend on these relocations to produce valid dwarf output. llvm-svn: 151655
* ARM BL/BLX instruction fixups should use relocations.Jim Grosbach2012-02-271-2/+4
| | | | | | | | | | | | | We on the linker to resolve calls to the appropriate BL/BLX instruction to make interworking function correctly. It uses the symbol in the relocation to do that, so we need to be careful about being too clever. To enable this for ARM mode, split the BL/BLX fixup kind off from the unconditional-branch fixups. rdar://10927209 llvm-svn: 151571

| | | | llvm-svn: 151418
* ARM Thumb symbol references in assembly need the low bit set.Jim Grosbach2012-02-241-0/+5
| | | | | | | | | Add support for a missed case when the symbols in a difference expression are in the same section but not the same fragment. rdar://10924681 llvm-svn: 151345

| | | | llvm-svn: 151213
* Switch the llvm::Triple class to immediately parse the triple string onChandler Carruth2012-02-211-4/+1
| | | | | | | | | construction. Simplify its interface, implementation, and users accordingly as there is no longer an 'uninitialized' state to check for. Also, fixes a bug lurking in the interface as there was one method that didn't correctly check for initialization. llvm-svn: 151024
* Remove dead code. Improve llvm_unreachable text. Simplify some control flow.Ahmed Charles2012-02-191-16/+11

| | | | llvm-svn: 150818
* Don't lazily allocate eh_frame. We're not lazily allocating things like the ↵David Chisnall2012-02-171-22/+26
| | | | | | | | LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense. Fix the type of eh_frame on Solaris so that Sun ld doesn't fail to combine them (thus making it impossible for the unwind library to find them and breaking exceptions). llvm-svn: 150814
* For ELF, also call fixSymbolsInTLSFixups() on expressions passed to ↵David Meyer2012-02-151-0/+9
| | | | | | EmitValue (literal values). Previously only called on expressions in instructions. New test cases added to tls.s, tls-i386.s. Resolves PR11981. llvm-svn: 150582

* Enable streaming of bitcodeDerek Schuff2012-02-062-4/+4
| | | | | | | This CL delays reading of function bodies from initial parse until materialization, allowing overlap of compilation with bitcode download. llvm-svn: 149918
* Modified the Enhanced Disassembler to create andSean Callanan2012-02-043-31/+40
| | | | | | | | | | cache disassemblers according to the string value of the target triple, not according to the enum of the triple CPU. The reason for this is that certain attributes of the instruction set are not reflected in the enum, but only in the string. llvm-svn: 149773
* Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which isAkira Hatanaka2012-02-033-0/+13
| | | | | | | | needed to emit a 64-bit gp-relative relocation entry. Make changes necessary for emitting jump tables which have entries with directive .gpdword. This patch does not implement the parts needed for direct object emission or JIT. llvm-svn: 149668
* Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses aKevin Enderby2012-01-311-0/+2
| | | | | | | | | symbol from an assignment. In this case the symbol did not have a fragment so MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should just have returned false in that case. llvm-svn: 149442

* Add support for the R_ARM_TARGET1 relocation, which should be given to ↵James Molloy2012-01-261-1/+3
| | | | | | | | relocations applied to all C++ constructors and destructors. This enables the linker to match concrete relocation types (absolute or relative) with whatever library or C++ support code is being linked against. llvm-svn: 149057
* Properly emit ctors / dtors with priorities into desired sectionsAnton Korobeynikov2012-01-251-7/+1
| | | | | | | | and let linker handle the rest. This finally fixes PR5329 llvm-svn: 148990
* ARM Darwin symbol ref differences w/o subsection-via-symbols.Jim Grosbach2012-01-241-1/+2
| | | | | | | | When not using subsections via symbols, the assembler can resolve symbol differences (including pcrel references) to non-local labels at assembly time, not just those in the same atom. llvm-svn: 148865
