The unit test is now disabled on non-asserts builds. The CF stack can be corrupted if you use CF_ALU_PUSH_BEFORE, CF_ALU_ELSE_AFTER, CF_ALU_BREAK, or CF_ALU_CONTINUE when the number of sub-entries on the stack is greater than or equal to the stack entry size and sub-entries modulo 4 is either 0 or 3 (on cedar the bug is present when number of sub-entries module 8 is either 7 or 0) We choose to be conservative and always apply the work-around when the number of sub-enries is greater than or equal to the stack entry size, so that we can safely over-allocate the stack when we are unsure of the stack allocation rules. reviewed-by: Vincent Lejeune <vljn at ovi.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199905 91177308-0d34-0410-b5e6-96231b3b80d8
