Created attachment 496547 [details] [diff] [review] Permanently turns on code predicated on VMCFG_PRECOMP_NAMES.
changeset: 5674:0f3e3b021435 user: firstname.lastname@example.org summary: Bug 618026 - VMCFG_PRECOMP_NAMES has very little use (r+lhansen) http://hg.mozilla.org/tamarin-redux/rev/0f3e3b021435
Had to rerun exactgc.as to fully get rid of the define (committed the generated file as well). Worth remembering that when #defines change, the tracer code may need an update.
