Bug ID: 31669
Summary: GlobalISel: Instruction selection failed
Product: new-bugs
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org

Reproduction script and source
When trying to compile simple source (see attached) with GlobalISel enabled it
generates the following error:
fatal error: error in backend: Instruction selection failed
And doesn't fallback to usage of old ISel.
The problematic code:
struct S {
void f() {}
};
S s;
int main() {
s.f();
return 0;
}
This happens once you introduce call of object's non-static method: if you
change f() to static or make it just a global function, error is not
reproduced.
