#13059: High memory usage during compilation -------------------------------------+------------------------------------- Reporter: domenkozar | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler | Version: 8.0.2-rc2 Resolution: | Keywords: Generics Operating System: Unknown/Multiple | Architecture: x86_64 Type of failure: Compile-time | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #5642, #11068 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Interesting! It looks to me as if the new behaviour is more faithfully following what the user said than the old behaviour. In this case, it is inlining `$gdm_size Foo $dStoreFoo` at every call of `size` at type `Foo`; and that's just what you'd expect from an INLINE pragma on the generic default method of `Store`. So maybe that was a bug in the old version, now fixed. And indeed, refraining from inlining the entire body of `size` at every call site seems like a good thing.
