| MasterDuke | also, guess this isn't really a big deal at all, but we create 3 temps, but only ever use two | 00:16 | |

| timotimo | it looks like it's specifically built to use the temp slots, since it takes that idx parameter | 00:58 | |
| and it does look like all functions that use force_bigint use it only(?) to provide a bigint into an mp op | 00:59 | ||

| scovit | MasterDuke: it feels to me that libtom should provide a macro to reserve an initialized mp_int on the stack, and that would be a saner approach | 10:30 | |
| tellable6 | scovit, I'll pass your message to MasterDuke | ||

| MasterDuke | anybody want to help me debug `This representation (P6num) cannot unbox to other types (for type TestNum)` thrown here github.com/perl6/nqp/blob/master/t...int.t#L137 when using this moarvm branch github.com/MoarVM/MoarVM/pull/1221 ? | 15:08 | |
| why doesn't nqp show the right line number in its backtrace? it says the line number of the str() sub, but then immediately after that it just says line 1 of the mainline, not the actual line it gets to | 15:32 | ||

| scovit | Hi MasterDuke, about your message of yesterday, why MoarVM does not allocate thos mp_int on the stack? I've looked at libtommath docs, there is mp_init_set and mp_init_set_int in that library. | 15:48 | |
|

| scovit | Basically it would be a trivial change to force_bigint static function, and you free that array on the global tc | 15:49 | |
| MasterDuke | scovit: good question, i don't know | ||
| my first goal is just to get moarvm/nqp/raku working with libtommath v1.2.0 with the fewest possible changes | 15:50 | ||
| scovit | me neither. I do not think it matters in terms of performance particularly | ||
| but code clarity for sure | |||
| Ok :) | |||
|
15:52

| MasterDuke | but after that there are a bunch of possible cleanups/simplifications. e.g., ltm 1.2 introduces some functions that we had created ourselves, so now wee can switch to theirs | 15:52 | |
| so i'll keep your idea in mind for that secondary work, thanks | 15:53 | ||
| scovit | you are welcome, thank to you to take care of upgrading the library | 15:54 | |

| brrt probably needs to check out the raku/perl side of things a bit more often... | 18:55 | ||
