[llvm-commits] CVS: llvm/lib/CWriter/Writer.cpp

[John Criswell]

Changes in directory llvm/lib/CWriter:

Writer.cpp updated: 1.111 -> 1.112

---
Log message:

Modified the code so that it generates (0) for setjmp() and abort() for
longjmp() (and does not include setjmp.h).
This is to fix some problems on Sparc while non-local jumps are still
unimplemented.
