<pre>Likely a duplicate of PR34479 and PR34482, but can be reproduced without polly.
Test.cpp:
class A {
void m_fn1();
void m_fn2(signed);
int mapmaxx;
};
void A::m_fn1() {
int y, a;
y = 1;
for (;; y++)
for (; mapmaxx;) {
a = y - 1;
for (; a <= y + 1; a++)
m_fn2(a);
}
}
Reproduce with:
clang -O3 -mllvm -enable-newgvn test.cpp -o - -S</pre>
