| | | | | | | | 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
* Add support for .cfi_signal_frame. Fixes pr11762.Rafael Espindola2012-01-234-7/+48

* Add a dump() implementation for sub-instruction MCOperands.Owen Anderson2012-01-191-0/+2
| | | | llvm-svn: 148493
* 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
* Tidy up. MCAsmBackend naming conventions.Jim Grosbach2012-01-183-10/+10

| | | | llvm-svn: 148364
* 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

* Add 'llvm_unreachable' to passify GCC's understanding of the constraintsChandler Carruth2012-01-101-0/+2
| | | | | | | | of several newly un-defaulted switches. This also helps optimizers (including LLVM's) recognize that every case is covered, and we should assume as much. llvm-svn: 147861
* Various crash reporting tools have a problem with the dwarf generated forKevin Enderby2012-01-101-17/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | assembly source when it generates the TAG_subprogram dwarf debug info for the labels that have nothing between them as in this bit of assembly source: % cat ZeroLength.s _func1: _func2: nop One solution would be to not emit the subsequent labels with the same address and use the next label with a different address or the end of the section for the AT_high_pc value of the TAG_subprogram. Turns out in llvm-mc it is not possible in all cases to determine of two symbols have the same value at the point we put out the TAG_subprogram dwarf debug info. So we will have llvm-mc instead of putting out TAG_subprogram's put out DW_TAG_label's. And the DW_TAG_label does not have a AT_high_pc value which avoids the problem. This commit is only the functional change to make the diffs clear as to what is really being changed. The next commit will be to clean up the names of such things like MCGenDwarfSubprogramEntry to something like MCGenDwarfLabelEntry. rdar://10666925 llvm-svn: 147860
