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.

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.

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.

Generate the correct EH frame section types on Solaris, this time without breaking other platforms...

llvm-svn: 150819

llvm-svn: 150818

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).

For ELF, also call fixSymbolsInTLSFixups() on expressions passed to EmitValue (literal values). Previously only called on expressions in instructions. New test cases added to tls.s, tls-i386.s. Resolves PR11981.

This CL delays reading of function bodies from initial parse until
materialization, allowing overlap of compilation with bitcode download.

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.

for emitting jump tables which have entries with directive .gpdword. This patch
does not implement the parts needed for direct object emission or JIT.

MCObjectWriter::IsSymbolRefDifferenceFullyResolved() should not have been
calling IsSymbolRefDifferenceFullyResolvedImpl() with a NULL fragment and should
just have returned false in that case.

Add support for the R_ARM_TARGET1 relocation, which should be given to 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.

This finally fixes PR5329

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.

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.
