#1290: ghc runs preprocessor too much -------------------------------------+------------------------------------- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Driver | Version: 6.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Changes (by ezyang): * milestone: ⊥ => 7.12.1 Comment: What if this information was cached in the interface file? Essentially, interface files should contain enough information for us to construct a `ModSummary`, and they are as recent as the source file we can just use this directly. (And we're going to read the interface file anyway shortly thereafter do check for recompilation avoidance.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1290#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
