Jim Grosbach 2c8e0ac85c MC asm parser macro argument count was wrong when empty.
evaluated to '1' when the argument list was empty (should be '0').

Michael J. Spencer fa39bd2d42 Implement relocation-overflow behavior for PE/COFF.
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.

Rafael Espindola c22c85c29c On ELF, create relocations to the abbreviation and line sections when producing
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.

Jim Grosbach 7b811d30d9 ARM BL/BLX instruction fixups should use relocations.
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.

Chandler Carruth 2d27b0f0ed Switch the llvm::Triple class to immediately parse the triple string on
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.

Kevin Enderby 86f94ce509 Put back the initializing the targets in the disassembler API with a comment as

David Chisnall 38e25ab513 Don't lazily allocate eh_frame. We're not lazily allocating things like the 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).

Sean Callanan bdce3885c4 Modified the Enhanced Disassembler to create and
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.

Akira Hatanaka f0b08445f6 Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which is
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.

Kevin Enderby e1a12cf3ee Fixed a crash in llvm-mc for Mach-O when a symbol difference expression uses a
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.

Jim Grosbach 35bc8f9159 ARM Darwin symbol ref differences w/o subsection-via-symbols.

Jim Grosbach d4dbd09d85 MCAssembler tweak for determining when a symbol difference is resolved.
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.
