[GHC] #10037: Several profiling tests give different results optimised vs. unoptimised
#10037: Several profiling tests give different results optimised vs. unoptimised -------------------------------------+------------------------------------- Reporter: simonmar | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Profiling | Version: 7.10.1-rc2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Blocked By: Test Case: | Related Tickets: Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Most of the differences are relatively harmless (mostly CAF attribution), but it would be nice to get this right. In the meantime I'll mark them expect_broken and point to this ticket. The following tests in `tests/profiling/should_run` are affected: {{{ scc001 T2552 ioprof callstack001 }}} -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10037> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

D2282 fixed cost center orders and removed `expect_broken` mark on `scc001`. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10037#comment:5> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I've opened Phab:D4498 as a possible fix for this. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/10037#comment:6> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
