Split eh.select / eh.typeid.for intrinsics into i32/i64 versions. This is needed, because they just "mark" register 2007-09-07T11:39:35ZAnton Korobeynikovasl@math.spbu.ru2007-09-07T11:39:35Zurn:sha1:8806c7b1f5317a9679a5779ffc08c552f2091bce

There is an impedance matching problem between LLVM and2007-08-27T15:47:50ZDuncan Sandsbaldrick@free.fr2007-08-27T15:47:50Zurn:sha1:6590b0457c5e28a7336ae31de194953d8127217a
gcc exception handling: if an exception unwinds through
an invoke, then execution must branch to the invoke's
unwind target. We previously tried to enforce this by
appending a cleanup action to every selector, however
this does not always work correctly due to an optimization
in the C++ unwinding runtime: if only cleanups would be
run while unwinding an exception, then the program just
terminates without actually executing the cleanups, as
invoke semantics would require. I was hoping this
wouldn't be a problem, but in fact it turns out to be the
cause of all the remaining failures in the LLVM testsuite
(these also fail with -enable-correct-eh-support, so turning
on -enable-eh didn't make things worse!). Instead we need
to append a full-blown catch-all to the end of each
selector. The correct way of doing this depends on the
personality function, i.e. it is language dependent, so
can only be done by gcc. Thus this patch which generalizes
the eh.selector intrinsic so that it can handle all possible
kinds of action table entries (before it didn't accomodate
cleanups): now 0 indicates a cleanup, and filters have to be
specified using the number of type infos plus one rather than
the number of type infos. Related gcc patches will cause
Ada to pass a cleanup (0) to force the selector to always
fire, while C++ will use a C++ catch-all (null).
