LLVM puts padding bytes in the __gcc_except_tab section after the
...
GCC_except_table label but before the Lexception, which the FDE references.
This causes problems as the FDE does not point to the start of an LSDA chunk.
Use an unnormalized uleb128 for the call-site table length that includes the
padding.

Preliminary patch to improve dwarf EH generation - Hooks to return Personality / FDE / LSDA / TType encoding depending on target / options (e.g. code model / relocation model) - MCIzation of Dwarf EH printer to use encoding information - Stub generation for ELF target (needed for indirect references) - Some other small changes here and there

Eliminate SetDirective, and replace it with HasSetDirective.
...
Default HasSetDirective to true, since most targets have it.
The targets that claim to not have it probably do, or it is
spelled differently. These include Blackfin, Mips, Alpha, and
PIC16. All of these except pic16 are normal ELF targets, so
they almost certainly have it.

Clean up LSDA name generation and use for SJLJ exception handling. This
...
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward
and making it a GV available for reference would be even better, but is
beyond the scope of what I'm looking to solve at this point.
Objective C++ code could generate function names that broke the previous
scheme. This fixes that.

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").

Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for

logical/sane approach to organizing all of the stuff that goes into writing out

Trivia: It *looks* like there would be functionality changes, however there aren't!
