Bug ID: 34579
Summary: APFloat asserts for x87 long doubles: "Can not have
more high bits to fill than integerPartWidth"
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Support Libraries
Assignee: unassignedb...@nondot.org
Reporter: a.sido...@samsung.com
CC: llvm-bugs@lists.llvm.org
A simple unit test:
TEST(APFloatTest, x87Largest) {
APFloat MaxX87Val = APFloat::getLargest(APFloat::x87DoubleExtended);
EXPECT_TRUE(MaxX87Val.isLargest()); // Don't crash.
}
Causes an assertion failure in APFloat::isSignificandAllOnes():
assert(NumHighBits <= integerPartWidth &&
"Can not have more high bits to fill than integerPartWidth");
