Rafael Espindola ca3e0ee8b3 Move the support for using .init_array from ARM to the generic
TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM,
on X86 it is not easy to find out if .init_array should be used or not, so
the decision is made via TargetOptions and defaults to off.

Add a command line option to llc that enables it.

David Chisnall 368d460d35 ... and it's probably best to use the correct alignment, rather than just guessing that it's the same as the size.

David Chisnall 8fa1716508 It turns out that putting an 8-byte symbol in a 4-byte section makes Solaris ld sulk. GNU ld is perfectly happy with it, which is worrying for a whole other set of reasons...
Thanks to Anton, Duncan and Rafael for helping me track this down.
Pointy hat to Rafael for introducing the bug in the first place.

Bill Wendling 734909a078 Modify the code that emits the module flags to use the new module flags accessor
method. This allows the target lowering code to not have to deal with MDNodes.

Also, avoid leaking memory like a sieve by not creating a global variable for
the image info section, but just emitting the code directly.

Bill Wendling 06df7725fc Add code to the target lowering object file module to handle module flags.
The MachO back-end needs to emit the garbage collection flags specified in the
module flags. This is a WIP, so the front-end hasn't been modified to emit these
flags just yet. Documentation and front-end switching to occur soon.

Bill Wendling e4cc332729 On MachO, the pointer to the personality function should always be in the
non_lazy_symbol_pointers section (__IMPORT,__pointers). Ignore the 'hidden' part
since that will place it in the wrong section.

Evan Cheng bbf3b0de8b Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.
There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

Bill Wendling d346304373 Add a __LD,__compact_unwind section.
If the linker supports it, this will hold the CIE and FDE information in a
compact format. The implementation of the compact unwinding emission is coming

Bill Wendling a48b1375df Remove a flag that would set the ".eh" symbol as .globl. MachO was the only one
who used this flag, and it now emits CFI and doesn't emit this anymore. All
other targets left this flag "false".

Rafael Espindola 08704349da Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, and
give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

Daniel Dunbar 4a7783b0c2 CodeGen: Eliminate a use of getDarwinMajorNumber().
- There is a minor semantic change here (evidenced by the test change) for
   Darwin triples that have no version component. I debated changing the default
   behavior of isOSVersionLT, but decided it made more sense for triples to be
   explicit.

Rafael Espindola 601a11edd4 Fix llvm-gcc bootstrap with gnu ld.
The problem was codegen guessing the wrong values and printing

	.section	.eh_frame,"aMS",@progbits,4

It is not clear at all if Codegen should try to guess, MC is the
one that should know the default flags.
