target/s390x: Fix tracing header path in TCG mem_helper.c

[PATCH] target/s390x: Fix tracing header path in TCG mem_helper.c

Posted by Philippe Mathieu-Daudé 1 year, 8 months ago

Commit c9274b6bf0 ("target/s390x: start moving TCG-only code
to tcg/") moved mem_helper.c, but the trace-events file is
still in the parent directory, so is the generated trace.h.

Ideally we should only use trace events from current directory.

Yes, that would be cleaner. Is it possible to move the relevant trace
events to the trace-events file in target/s390x/tcg/?

Mmm, I was wondering if maybe that would be the better approach.

A quick grep suggests the only other place doing a "../trace.h"
include is in include/hw/xen/interface/hvm/hvm_op.h, which is
unrelated, because it's pulling in the non-autogenerated
include/hw/xen/interface/trace.h.
