* Darwin 'as' silently ignores the '.ident' directive.Jim Grosbach2011-03-081-0/+7
| | | | llvm-svn: 127258
* Preliminary support for ARM frame save directives emission via MI flags.Anton Korobeynikov2011-03-053-0/+54
| | | | | | | This is just very first approximation how the stuff should be done (e.g. ARM-only for now). More to follow. llvm-svn: 127101
* Some first rudimentary support for ARM EHABI: print exception table in "text ↵Anton Korobeynikov2011-03-052-0/+56

* PR9352: Always emit a relocation for weak symbols. Not emitting relocationsEli Friedman2011-03-031-0/+19
| | | | | | | | for calls to weak symbols with a definition has the appearance of working with LLVM-generated code because weak symbol definitions are put in their own sections. llvm-svn: 126933

* Restore r125595 (reverted in r126336) with modifications:Joerg Sonnenberger2011-02-243-2/+25
| | | | | | | Introduce a variable in the AsmParserExtension whether [] is valid in an expression. If it is true, parse them like (). Enable this for ELF only. llvm-svn: 126443

| | | | | | | - Don't leak parsed operands during tokenization. - Don't leak printed insts in llvm-mc. llvm-svn: 126381
* Revert r125595, which is an X86-only undocumented assembly syntax extensionJim Grosbach2011-02-231-18/+0
| | | | | | | | | | enabled for all targets. Non-X86 targets should not have this behavior enabled by default. Joerg, if you would like to resubmit with the behavior conditionalized to be X86-ELF only, that's fine. llvm-svn: 126336

| | | | | | Fixes PR9292. llvm-svn: 126330

* Fix comparator used for looking up previously instantiated EDDisassemblers.Shantonu Sen2011-02-091-2/+4
| | | | | | | | | Now, Syntax is only used as a tie-breaker if the Arch matches. Previously, a request for x86_64 disassembler followed by the i386 disassembler in a single process would return the cached x86_64 disassembler. Fixes <rdar://problem/8958982> llvm-svn: 125215

* Teach ARM/MC/ELF about gcc compatible reloc output to get past odd linkageJason W Kim2011-02-071-3/+45
| | | | | | | | | | | | | | | | | | failures with relocations. The code committed is a first cut at compatibility for emitted relocations in ELF .o. Why do this? because existing ARM tools like emitting relocs symbols as explicit relocations, not as section-offset relocs. Result is that with these changes, 1) relocs are now substantially identical what to gcc outputs. 2) larger apps (including many spec2k tests) compile, cross-link, and pass Added reminder fixme to tests for future conversion to .s form. llvm-svn: 124996
* Teach ARM/MC/ELF about EF_ARM_EABI_VERSION. The magic number is set toJason W Kim2011-02-041-2/+15

* Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.Jason W Kim2011-02-042-5/+10
| | | | | | | | | | | | | | | | (yes, this is different from R_ARM_CALL) - Adds a new method getARMBranchTargetOpValue() which handles the necessary distinction between the conditional and unconditional br/bl needed for ARM/ELF At least for ARM mode, the needed fixup for conditional versus unconditional br/bl is identical, but the ARM docs and existing ARM tools expect this reloc type... Added a few FIXME's for future naming fixups in ARMInstrInfo.td llvm-svn: 124895
