#12745: Compile cmm file for register allocator stats -------------------------------------+------------------------------------- Reporter: tjakway | Owner: tjakway Type: task | Status: new Priority: lowest | Milestone: Component: Compiler (NCG) | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #12744 | Differential Rev(s): Phab:D2621 Wiki Page: | -------------------------------------+------------------------------------- Comment (by tjakway): The issue stems from RegAlloc.Graph.Main lines 100-106: {{{ -- If any of these dump flags are turned on we want to hang on to -- intermediate structures in the allocator - otherwise tell the -- allocator to ditch them early so we don't end up creating space leaks. let dump = or [ dopt Opt_D_dump_asm_regalloc_stages dflags , dopt Opt_D_dump_asm_stats dflags , dopt Opt_D_dump_asm_conflicts dflags ] }}} Without the dump flags the intermediate structures we need are scrapped. I propose adding a flag to keep the intermediates without printing them. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12745#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
