- <rdar://problem/5667688> wrong EH information might be used
- Created new kGroupSubordinate reference kind to model group comdat. The "signature" atom
- has kGroupSubordinate references to the other atoms in the group. If the signature atom
- is coalesced away, the linker follows kGroupSubordinate references and throws away the
- other members of the group.
- * unit-tests/test-cases/eh-coalescing: added test case
- * src/ld.cpp: added markDead() and use propagate to subordinates
- * src/Architectures.hpp: added kGroupSubordinate
- * src/MachOReaderRelocatable.hpp: add kGroupSubordinate reference from a function to its .eh atom
- and if used, from .eh atom to its LSDA atom.
- * src/MachOWriterExecutable.hpp: handle kGroupSubordinate like kNoFixUp
