* Now Igor, throw the switch...give my creation life!Bill Wendling2011-10-17
| | | | | | | | | | | | | | | | | | Use the custom inserter for the ARM setjmp intrinsics. Instead of creating the SjLj dispatch table in IR, where it frequently violates serveral assumptions -- in particular assumptions made by the landingpad instruction about what can branch to a landing pad and what cannot. Performing this in the back-end allows us to violate these assumptions without the IR getting angry at us. It also allows us to perform a small optimization. We can shove the address of the dispatch's basic block into the function context and not have to add code around the setjmp to check for the return value and jump to the dispatch. Neat, huh? <rdar://problem/10116753> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142294 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM NEON "vmov.i8" immediate assembly parsing and encoding.Jim Grosbach2011-10-17
| | | | | | | | | NEON immediates are "interesting". Start of the work to handle parsing them in an 'as' compatible manner.
