@topolarity Is there a way to attach a message? Would be helpful to differentiate between minor and major GC

[topolarity]

In Tracy, we distinguish full sweeps based on the color associated with the event. That's one of the cases we haven't pulled up to a generic API yet:

julia/src/gc.c

Lines 3122 to 3127 in 552dd4c

	#ifdef USE_TRACY
	if (sweep_full) {
	TracyCZoneCtx ctx = *(JL_TIMING_CURRENT_BLOCK->tracy_ctx);
	TracyCZoneColor(ctx, 0xFFA500);
	}
	#endif

jl_timing_printf and jl_timing_show_* also allow associating strings with events, so we could use that if ITTAPI supports string metadata. Or did you have something more specialized in mind?

[pchintalapudi]

I feel like if we had a conditional event that would be sufficient here.

Late to the review, but once again nice work - Nice to have this on master
