10:45 timotimo the "serialized blob in the string heap" thing is from QASTCompilerMAST's deserialization_code method

12:35 vendethiel joined #moarvm
12:57 JimmyZ_ obj_facts->usages--  # usages means version, right?
12:58 JimmyZ_ and I don't known what MVM_spesh_use_facts does
12:58 JimmyZ_ *know
13:08 vendethiel joined #moarvm
13:23 jnthn No, it's not about version, it's about how many things use that version
13:23 jnthn Facts are held per version
13:43 vendethiel joined #moarvm
13:44 JimmyZ_ oh
13:49 JimmyZ_ what about MVM_spesh_use_facts?
13:51 JimmyZ_ I see obj_facts->usages-- always with MVM_spesh_use_facts(..., obj_fact);
14:16 vendethiel joined #moarvm
15:04 jnthn usages is about the variable the fact descibes
15:04 jnthn use_facts is saying "I'm using this fact fro something"
15:04 jnthn And controls guard emission

16:39 timotimo .tell JimmyZ_ if we manage to get the number of superfluous set instructions that are created from QASTCompilerMAST down a little, we'll get benefits all over the whole system: fewer temp register means smaller frame objects, smaller facts database in spesh, fewer registers kept alive because they have to survive until they hit a deopt point, ...
16:40 timotimo so if you want a "little" project, go for it :)
