* Update SimplifyCFG for atomic operations.Eli Friedman2011-08-151-0/+43
| | | | | | | | | | 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? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137691 91177308-0d34-0410-b5e6-96231b3b80d8
* Move "atomic" and "volatile" designations on instructions after the opcodeEli Friedman2011-08-121-4/+4
| | | | | | | | | | | | 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
* Test case for r105914.Benjamin Kramer2010-06-131-0/+11

* make simplifycfg insert an llvm.trap before the 'unreachable' it introducesChris Lattner2010-05-081-3/+17
| | | | | | | | | | | | | | | | | | | | | | when it detects undefined behavior. llvm.trap generally codegens into some thing really small (e.g. a 2 byte ud2 instruction on x86) and debugging this sort of thing is "nontrivial". For example, we now compile: void foo() { *(int*)0 = 42; } into: _foo: pushl %ebp movl %esp, %ebp ud2 Some may even claim that this is a security hole, though that seems dubious to me. This addresses rdar://7958343 - Optimizing away null dereference potentially allows arbitrary code execution git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103356 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix PR2967 by not deleting volatile load/stores that occur before unreachable.Chris Lattner2008-10-291-0/+19
I don't really see this as being needed, but there is little harm from doing it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58385 91177308-0d34-0410-b5e6-96231b3b80d8
