* Prune some includes and forward declarations.Craig Topper2012-03-261-1/+1
| | | | llvm-svn: 153429
* 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
* MCAssembler tweak for determining when a symbol difference is resolved.Jim Grosbach2012-01-181-1/+2
| | | | | | | | | | | | If the two fragments are in the same Atom, then the difference expression is resolvable at compile time. Previously we were checking that they were in the same fragment, but that breaks down in the presence of instruction relaxation which has multiple fragments in the same atom. rdar://10711829 llvm-svn: 148423
* MC tweak symbol difference resolution for non-local symbols.Jim Grosbach2012-01-171-2/+2
| | | | | | | | | | | | | | When the non-local symbol in the expression is in the same fragment as the second symbol, the assembler can still evaluate the expression without needing a relocation. For example, on ARM: _foo: ldr lr, (_foo - 4) rdar://10348687 llvm-svn: 148341
* Darwin assembler improved relocs when w/o subsections_via_symbols.Jim Grosbach2011-12-071-1/+6
| | | | | | | | When the file isn't being built with subsections-via-symbols, symbol differences involving non-local symbols can be resolved more aggressively. Needed for gas compatibility. llvm-svn: 146054
* Tidy up. Hard tabs.Jim Grosbach2011-12-061-1/+1
| | | | llvm-svn: 145878
* Switch MCAssembler to method names starting w/ lower-case.Jim Grosbach2011-12-061-1/+1
| | | | | | per http://llvm.org/docs/CodingStandards.html#ll_naming llvm-svn: 145873
* Formatting and typo.Eric Christopher2011-09-081-2/+3
| | | | llvm-svn: 139325
* Fix a Darwin x86_64 special case of a jmp to a temporary symbol from an atomKevin Enderby2011-09-081-0/+10
| | | | | | without a base symbol that must not have a relocation entry. llvm-svn: 139316
* MachOWriter: Don't crash on fixups with arithmetic, emit a relocation ↵Benjamin Kramer2011-08-121-2/+6
| | | | | | instead. This matches what as does. llvm-svn: 137414
* Don't truncate MachO addresses.Jim Grosbach2011-08-091-1/+1
| | | | | | | | | | | | | | Assigned symbol addresses get truncated to 32-bits, even on 64-bit platforms. That's obviously bogus. For example, .globl _foo .equ _foo, 0x987654321ULL rdar://9922863 llvm-svn: 137158
* Rename TargetAsmBackend to MCAsmBackend; rename createAsmBackend to ↵Evan Cheng2011-07-251-1/+1

* Move TargetAsmParser.h TargetAsmBackend.h and TargetAsmLexer.h to MC where ↵Evan Cheng2011-07-231-1/+1
| | | | | | they belong. llvm-svn: 135833
* Refactor MachO relocation generaration into the Target directories.Jim Grosbach2011-06-241-985/+19
| | | | | | | | | Move the target-specific RecordRelocation logic out of the generic MC MachObjectWriter and into the target-specific object writers. This allows nuking quite a bit of target knowledge from the supposedly target-independent bits in lib/MC. llvm-svn: 133844
* tidy up whitespace.Jim Grosbach2011-06-241-1/+1

* Fix a ton of comment typos found by codespell. Patch byChris Lattner2011-04-151-2/+2

* Fix a bug introduced by my patch yesterday: BL is a 4-byte instructions like ↵Owen Anderson2011-03-231-3/+2
| | | | | | BLX, rather than a 2-byte instruction like B. llvm-svn: 128169
* RIT_ARM_ThumbBranch32Bit relocations are not used and should never be generated.Owen Anderson2011-03-221-6/+2
| | | | | | | This fixes kimwitu++, bullet, and tramp3dv4 with the ARM integrated assembler. Fixes <rdar://problem/9165738>. llvm-svn: 128117
* Silence compiler warning about case values not being in the enumerated typeDuncan Sands2011-03-151-1/+1
| | | | | | MCFixupKind. This is the same technique that is used elsewhere in MC. llvm-svn: 127676
* Fixes warnings emitted by Visual Studio 2010 compiler.Oscar Fuentes2011-03-011-2/+2
| | | | | | Patch by Erik Olofsson! llvm-svn: 126796
* Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.Jason W Kim2011-02-041-1/+2
| | | | | | | | | | | | | | | | (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
* Fix bogus assert condition noticed by Csaba Raduly.Evan Cheng2011-02-011-2/+2
| | | | llvm-svn: 124645
* Completed :lower16: / :upper16: support for movw / movt pairs on Darwin.Evan Cheng2011-01-141-9/+126
| | | | | | | | - Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first. - Added support for Thumb2 :lower16: and :upper16: fix up. - Added :upper16: and :lower16: relocation support to mach-o object writer. llvm-svn: 123424

* MC/Mach-O/ARM: We always use the SECTDIFF reloc type on ARM, which isDaniel Dunbar2010-12-221-6/+1

* MC/Mach-O/ARM: Clone off an ARM version of RecordScatteredRelocation until I ↵Daniel Dunbar2010-12-221-4/+68

* GCC objects to the two sides of a conditional expression having different enumMatt Beaumont-Gay2010-12-211-2/+2
| | | | | | | types, but they're just getting converted to unsigned anyway, so cast first (and ask questions later). llvm-svn: 122377

* MC/Mach-O: On second thought, use a custom hook for enabling aggressiveDaniel Dunbar2010-12-171-0/+3
| | | | | | | | | | IsSymbolRefDifferenceFullyResolved, it turns out this does change behavior on enough cases for x86-32 that I would rather wait a bit on it. - In practice, we will want to change this eventually because it only means we generate less relocations (it also eliminates the need for the horrible '.set' hack that Darwin requires in some places). llvm-svn: 122042
* MC/Mach-O: Implement IsSymbolRefDifferenceFullyResolved.Daniel Dunbar2010-12-171-0/+25
| | | | | | | | - Unlike for fixups, we always do the "reliable" thing (not just for x86_64). - Since Darwin 'as' would typically reject things that using this will allow, we don't need to worry about compatibility. llvm-svn: 122038
