Bug #: 13615
Summary: APInt::udivrem says 1/1 == -1
Product: libraries
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Support Libraries
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
Using r161995:
APInt a(32, 1), b(32, 1), c, d;
APInt::udivrem(a, b, c, d);
dbgs() << "dividing " << a << " by " << b << " yields " << c << " rem " << d <<
"\n";
prints:
dividing 1 by 1 yields -1 rem 0
Using sdivrem does not seem to help. Unless I'm missing something, 1/1 != -1.
