Move "atomic" and "volatile" designations on instructions after the opcode

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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137527 91177308-0d34-0410-b5e6-96231b3b80d8

remove asmparser support for the old getresult instruction, which has been subsumed by extractvalue.

Fix an infinite alternation in JumpThreading where two transforms would repeatedly undo each other. The solution is to perform more aggressive constant folding to make one of the edges just folded away rather than trying to thread it.

Fixes . Discovered with CSmith. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129538 91177308-0d34-0410-b5e6-96231b3b80d8

PR9446: RecursivelyDeleteTriviallyDeadInstructions can delete the instruction

after the given instruction; make sure to handle that case correctly. (It's difficult to trigger; the included testcase involves a dead block, but I don't think that's a requirement.) While I'm here, get rid of the unnecessary warning about SimplifyInstructionsInBlock, since it should work correctly as far as I know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128782 91177308-0d34-0410-b5e6-96231b3b80d8

prevent jump threading from merging blocks when their address is

taken (and used!). This prevents merging the blocks (invalidating the block addresses) in a case like this: #define _THIS_IP_ ({ __label__ __here; __here: (unsigned long)&&__here; }) void foo() { printf("%p\n", _THIS_IP_); printf("%p\n", _THIS_IP_); printf("%p\n", _THIS_IP_); } which fixes PR4151. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125829 91177308-0d34-0410-b5e6-96231b3b80d8

Tolerate degenerate phi nodes that can occur in the middle of optimization

Re-apply r124518 with fix. Watch out for invalidated iterator.

Revert r124518. It broke Linux self-host.

Re-commit r124462 with fixes. Tail recursion elim will now dup ret into unconditional predecessor to enable TCE on demand.
