Currently, Julia exceptions trigger an
s_trap 2, which causes thewaithandler to hang, and doesn't communicate any useful information about what caused the exception. This PR replaces that mechanism with a similar mechanism to the one CUDAnative uses, but with the goal to provide proper per-kernel exceptions (as opposed to throwing the exception at the next API call).Todo:
@rocprintcalls to fix kernels with exceptionsfreefor malloc'd dataActually make the ring buffer a ring buffer (currently it's a list)ExceptionEntry)malloc'd data when the kernel exits by default
