2018-09-03ops.tab: Fix potentially unsafe optimization of raise/2Björn Gustavsson
The operands for the raise/2 instruction are almost always in x(2) and x(1). Therefore the loader translates the raise/2 instruction to an i_raise/0 instruction which uses the values in x(2) and x(1). If the operands happens to be in other registers, the loader inserts move/2 instruction to move them to x(2) and x(1). The problem is that x(3) is used as a temporary register when generating the move/2 instructions. That is unsafe if the Value operand for raise/2 is x(3). Thus: raise x(0) x(3) will be translated to: move x(0) x(3) move x(3) x(1) move x(3) x(2) i_raise The Trace will be written to both x(2) and x(1). The current compiler will never use x(3) for the Value operand, so there is no need to patch previous releases. But a future compiler version might allocate registers differently.

2018-08-03erts: Fix seq_trace to not clear token for system messagesLukas Larsson
A lot of erts internal messages used behind APIs to create non-blocking calls, e.g. port_command, would cause the seq_trace token to be cleared from the caller when it should not. This commit fixes that and adds asserts that makes sure that all messages sent have to correct token set. Fixes: ERL-602

Before this change, if a write to the uds failed due to EMFILE to ETOOMANYREFS the entire vm would crash. This change makes it so that an SIGCHLD is simulated to that the error is propagated to the user instead of terminating the VM.
