Hello all,
I am an user of LLVM Interpreter. The situation I encounter is as follows:
---------------------------------------------------------------------
main.c:
jmp_buf buf;
int main() {
if (setjmp(buf) == 0) {
...
} else {
execute();
}
}
---------------------------------------------------------------------
execute.c:
execute() {
EE->runFunction(Func, Args); // EE is LLVM interpreter, function body
// of Func is in Func.ll
}
---------------------------------------------------------------------
Func.ll:
def void @Func() {
.
call void @foo() noreturn
.
}
---------------------------------------------------------------------
foo.c:
void foo() {
longjmp(buf, 1);
}
---------------------------------------------------------------------
If Interpreter execute a LLVM function Func, It may not update stack frame
of
interpreter simultaneously. An error may occur when recall
interpreter::run().
Does anyone encounter the same problem and have any idea to solve it?
Thanks a lot
