2012-02-06Enable streaming of bitcodeDerek Schuff
This CL delays reading of function bodies from initial parse until materialization, allowing overlap of compilation with bitcode download. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149918 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-04Modified the Enhanced Disassembler to create andSean Callanan
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149773 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-03Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which isAkira Hatanaka
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149668 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-31Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses aKevin Enderby
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149442 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-24ARM Darwin symbol ref differences w/o subsection-via-symbols.Jim Grosbach
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148865 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18MCAssembler tweak for determining when a symbol difference is resolved.Jim Grosbach
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148423 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-17MC tweak symbol difference resolution for non-local symbols.Jim Grosbach
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.

2012-01-10Add 'llvm_unreachable' to passify GCC's understanding of the constraintsChandler Carruth
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147861 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-10Various crash reporting tools have a problem with the dwarf generated forKevin Enderby
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 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147860 91177308-0d34-0410-b5e6-96231b3b80d8
