[llvm-commits] llvm-gcc: generate itanium style exception handling code

[Duncan Sands]

This patch causes llvm-gcc to output itanium style exception handling
code.  It does not turn on zero cost exceptions (they cannot be turned
on until llvm-gcc is capable of correctly building the unwinder in the
runtime library - this is PR1379).  Tested by bootstrapping the compiler
and running the entire testsuite.  There were no regressions.

Ciao,

Duncan.
