Here's a simpler example:
struct A {
int *m1;
int m2;
};
void f1(int *p1, int p2);
void __attribute__((always_inline)) f2(A p5) { f1(p5.m1, p5.m2); }
void func(void*);
void func(const int &, const int&);
int cond();
void f() {
while (cond()) {
int x;
func(x, 0);
while (cond()) {
char y;
func(&y);
char j;
func(&j);
char I;
func(&I);
func(0, 0);
A g;
g.m1 = &x;
f2(g);
}
}
}
clang -cc1 -emit-obj -mdisable-fp-elim -g -O1 -std=c++11 -o /dev/null -x
c++ crash.cpp
This reproduces at -O1 (maybe the original did too, but I think I checked -
probably due to the lack of always_inline) & removes a bunch of the
template guff.
Yeah, it's still a bit weird with the body of the two loops, various
variables leaking out to create register pressure, etc - perhaps thecre's a
more regular structure that could be used to make that more obvious, but
it's at least relatively simple now.
*shrug* might be useful to you, I don't know - but the test case seems
particularly hard to maintain as-is given all the debug info metadata in it
along with no original source and bugpoint reduction of the IR.
