[LLVMdev] built-in longjmp and setjmp
I have another basic question about setjmp/longjmp.
When I compile and run the following program, is it expected that global
variable gi2 will be incremented twice? It seems that the code generated
with clang and llc increments it only once (line 37-43 of attached file).
$ clang setjmp6.c -o setjmp6.arm.ll -emit-llvm -O3 -S -ccc-host-triple
arm-unknown-darwin -ccc-clang-archs arm
$ llc

Non-volatile local variables are not preserved by setjmp(), so this program can print whatever it wants.
