| Geth | MoarVM: 34fac5f4ef | (Stefan Seifert)++ | src/spesh/optimize.c Enable optimization of speshresolve with ustable guard indexes Even if there's no clearly winning guard index, we can at least replace speshresolve by sp_speshresolve and get rid of the logging and enable JIT compilation for that frame. The comments suggest that it has always been intended this way and that the return was just an oversight happening due to the 2 halfs of the function being written a month apart. |

| nine | A new data point: disabling the JIT hurts Inline::Perl5's master branch a lot (~33 %) while it hurts my optimized branch just a little (~13 %). | 09:47 | |
| And another one: according to perf enabling the profiler reduces time spent in MVM_interp_run by ~ 90 %. And that time consists mostly of entering JITed code. | 09:49 | ||

| timotimo | nine: i can suggest activating that env var that lets the jit create a pid.map file in itmp | 19:22 | |
| yoleaux | 10:55Z <Xliff> timotimo: Do we really want people to be able to set an attribute using the $. form? | ||
| timotimo | for use with perf | ||
| in /tmp* | |||
| nine | timotimo: oh, how do I then use that with perf? | 19:56 | |
| Ah, perf report --symfs=/tmp | 20:09 | ||
