the exception object, and nothing can overwrite it, once we start
throwing. The only bad part, is that the stack remains large.
Flaws in g++'s exception handling. The stack pointer is restored from
stack, we want to match rs6000, and propagate the stack pointer from
time of throw, down, to the catch place.
The below points out some flaws in g++'s exception handling, as it now
stands.
Only exact type matching of throw types works (references work also),
catch variables cannot be used. Only works on a Sun sparc running SunOS
4.1.x. Unwinding to outer catch clauses works. All temps and local
variables are cleaned up in all unwinded scopes. Completed parts of
partially constructed objects are not cleaned up. Don't expect
exception handling to work right if you optimize, in fact the compiler
will probably core dump. If two EH regions are the exact same size, the
backend cannot tell which one is first. It punts by picking the last
one, if they tie. This is usually right. We really should stick in a
nop, if they are the same size.
If we fall off the end of a series of catch blocks, we return to the
flow of control in a normal fasion. But this is wrong, we should
rethrow.
Only exact type matching or reference matching of throw types works.
Only works on a SPARC machines (like Suns), and i386 machines. Partial
support is also in for rs6000, hppa, m68k and mips machines, but a stack
unwinder called __unwind_function has to be written, and added to
libgcc2 for them. All completely constructed temps and local variables
are cleaned up in all unwinded scopes. Completed parts of partially
constructed objects are not cleaned up. Don't expect exception handling
to work right if you optimize, in fact the compiler will probably core
dump. If two EH regions are the exact same size, the backend cannot
tell which one is first. It punts by picking the last one, if they tie.

the handler's handler to protect the whole series of handlers is the
right way to go.
right way to go. This part is wrong. We should call terminate if an
exception is thrown while doing things like trying to copy the exception
object.
The EH object is copied like it should be, if it is passed by value,
otherwise we get a reference directly to it.
Exception specifications are handled syntax wise, but not semantic wise.
build_exception_variant should sort the incoming list, so that is
implements set compares, not exact list equality. Type smashing should
smash exception specifications using set union.
EH objects make it through unwinding, but are subject to being
overwritten as they are still past the top of stack. Don't throw
automatic objects if this is a problem.
Thrown objects are allocated on the heap, in the usual way, but they are
never deleted. They should be deleted by the catch clauses.
Exceptions in catch handlers now go to outer block.
In stmt.c, expand_end_bindings attempts to eliminate the generation of
destructors for a binding contour if the code would be unreachable (last
insn == BARRIER). In this case, interim_eh_hook is never called for the
end of the lifetimes of auto variables, so the compiler generates
invalid assembler (the end label for the scope is never declared, and
destructor code isn't generated on the exception path).
