Bug ID: 21497
Summary: miscompilation after SVN r220256
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Backend: X86
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Slightly reduced test case:
// RUN: %clang -fPIC -target i686-windows-itanium -c %s
extern int a();
extern int b();
extern int c();
extern int d();
int test(long long ll, void *pv) {
int result = 1;
switch (ll) {
case 1:
result = a();
break;
case 2:
result = c();
break;
case 3:
result = d();
break;
case 4:
if (pv == 0) {
(void)d();
result = b();
} else {
}
break;
}
return (result);
}
Setting SetDirectiveSuppressesReloc to true corrects the issue.
