Simplify.

the pointer MMI keeps will start out with object-file format specific stuff

add hooks to hang target-specific goop off MachineModuleInfo,
move MachineFunctionInfo virtual method out of line to give it
a home.

Rework getPersonalityIndex slightly - 0 is now a valid and not-NULL
personality function.

llvm-svn: 80153

If we're emitting additional CIEs due to personality functions
don't emit the default one. Explicitly check for the NULL
CIE later.

Nuke trailing whitespace.

Use setPreservesAll and setPreservesCFG in CodeGen passes.

implement a new magic global "llvm.compiler.used" which is like llvm.used, but
doesn't cause ".no_dead_strip" to be emitted on darwin.

llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

DebugLabelFolder ruthlessly deletes redundant labels. However, sometimes the redundant labels is referenced by debug info somewhere else. This patch provies a way so that dwarf writer can mark labels

Rename getAnalysisToUpdate to getAnalysisIfAvailable.

Removoe MachineModuleInfo methods (and related DebugInfoDesc class hierarchy) that were used to handle debug info.

llvm-svn: 62199

Keep "has debug info" big in MachineModuleInfo to avoid circular dependency between AsmPrinter and CodeGen.

Fix a couple of Dwarf bugs.
- Emit DW_AT_byte_size for struct and union of size zero.
- Emit DW_AT_declaration for forward type declaration.

an array that is empty. Instead of requiring this array, allow a null pointer.
