| MasterDuke | huh. why would something take longer with just MVM_SPESH_OSR_DISABLE=1 than with MVM_SPESH_DISABLE=1 ? | 00:53 | |
| timo1: i did try adding `&& arg_type != MVM_CALLSITE_ARG_INT` to the conditional, but that just caused a segfault, and i didn't investigate that further | 00:56 | ||
| i sort of hope there's a solution that gets us to specializing for uint, not int | 00:57 | ||
| :q | |||
| ww | |||
| something about the facts gathered perhaps? | 01:01 | ||

| MasterDuke | ugh. i looked at pretty much everywhere a `*_i` op is used and added something for `*_u` if it wasn't there already, but still no change | 01:19 | |
| in src/spesh/* | 01:20 | ||
| timo1 | "no change" from "causes a segfault"? | 01:43 | |
| MasterDuke | "no change" eq "no segfault, but not any faster" | 02:38 | |
| gist.github.com/7c8c1862d593a8ea09...51c6d2f435 should be my current diff | 02:40 | ||
| updated with some jit addition | 02:53 | ||

| timo1 | does MVM_op_get_mark update correctly when update_ops runs? | 10:00 | |
| in jit_emit_primitive, do we have to use a different mov for p6òget_u32 to get the right sign extend behaviour? | 10:03 | ||

| timo1 | if you post a bit of spesh log maybe with a function that used to bail arg spesh because of uint and now succeeds, and maybe if that same frame ever gets mentioned as inlined? i can take a look later | 13:55 | |
