#10247: 5x increase in total memory allocation for `prof-doc-fib` test since 2011 -------------------------------------+------------------------------------- Reporter: thomie | Owner: Type: task | Status: new Priority: high | Milestone: Component: Profiling | Version: 7.10.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton): Now testing with HEAD, on a hunch I tried `make fast TEST=prof-doc-fib` (which only runs the profasm test way), and I got a number which (exactly!) matched the previous prof-doc-fib.prof.sample value. So I think that file was produced with profasm. (Would be nice to record this information...) prof-doc-last really did regress from 7.8.4 to 7.10.1, though: {{{ total alloc = 408,053,512 bytes (excludes profiling overheads) -- 7.8.4 total alloc = 648,053,536 bytes (excludes profiling overheads) -- 7.10.1 }}} presumably due to b709f0a047dc036de15dc43d3b0ab88d3e32c5e6. But the extra allocations go away when optimizations are enabled, so I guess it's okay. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10247#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
