Bug ID: 22198
Summary: libunwind: __builtin_unreachable is not available on
gcc prior to version 4.5
Product: libc++abi
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
__builtin_unreachable is used unconditionally in DwarfInstructions.hpp. We
should maybe just __builtin_trap() instead:
assert(0 && "getCFA(): unknown location");
__builtin_unreachable();
