SimplifyCFG: If we have a PHI node that can evaluate to NULL and do a load or store to the address returned by the PHI node then we can consider this incoming value as dead and remove the edge pointing there, unless there are instructions that can affect control flow executed in between.2011-08-26T01:22:29ZBenjamin Kramerbenny.kra@googlemail.com2011-08-26T01:22:29Zurn:sha1:98d6d2372feb2f8bb4c3941b278027499cbfc00b
In theory this could be extended to other instructions, eg. division by zero, but it's likely that it will "miscompile" some code because people depend on div by zero not trapping. NULL pointer dereference usually leads to a crash so we should be on the safe side.
This shrinks the size of a Release clang by 16k on x86_64.

Update SimplifyCFG for atomic operations.2011-08-15T23:59:28ZEli Friedmaneli.friedman@gmail.com2011-08-15T23:59:28Zurn:sha1:8176388d65083339efdfa5bee63e620c6bd05aa1
This commit includes a mention of the landingpad instruction, but it's not
changing the behavior around it. I think the current behavior is correct,
though. Bill, can you double-check that?

Move "atomic" and "volatile" designations on instructions after the opcode2011-08-12T22:50:01ZEli Friedmaneli.friedman@gmail.com2011-08-12T22:50:01Zurn:sha1:f03bb260c90ad013aa4e55af36382875011c95b8
of the instruction.
Note that this change affects the existing non-atomic load and store
instructions; the parser now accepts both forms, and the change is noted
in the release notes.
