We can now add a CFGGraph on a BaselineScript. But we never remove it. We should at least report this memory! Add a memory reporter to see how much memory this takes.
Depends on: 1310155
Priority: -- → P3
I think that is all that is needed to add this memory reporter?

Comment on attachment 8857897 [details] [diff] [review] Add memory reporter Review of attachment 8857897 [details] [diff] [review]: ----------------------------------------------------------------- So CFGSpace already had a sizeOfExcludingThis() function, but it wasn't being used? Huh, that's a little surprising. Oh well, it comes in useful now. ::: js/src/vm/TypeInference.cpp @@ +4490,5 @@ > *typePool += types.typeLifoAlloc().sizeOfExcludingThis(mallocSizeOf); > if (jitZone()) { > *baselineStubsOptimized += > jitZone()->optimizedStubSpace()->sizeOfExcludingThis(mallocSizeOf); > + *cachedCFG += jitZone()->cfgSpace()->sizeOfExcludingThis(mallocSizeOf); Normally '->' is paired with 'sizeOfIncludingThis' instead of 'sizeOfExcludingThis'. But in this case the code is correct. Can you add a comment above the baselineStubsOptimized line like this: "// These functions return pointers to struct that are embedded within JitZone, which is why we use sizeOfExcludingThis()."
