#7830: Error: operand out of range -------------------------------------+------------------------------------- Reporter: erikd | Owner: Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 7.8.1-rc1 Resolution: | Keywords: Operating System: Linux | Architecture: powerpc Type of failure: Installing GHC | Test Case: failed | Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by erikd): Compiling git HEAD (currently c8d438fb02 but anything after commit 5d57087e31 is basically the same) fails on PowerPC due to the issue in this ticket (comment 19 and later). When it fails, the generated assembler for `compiler/cmm/PprC.hs` is about 300000 lines of code, but if I compile the tree at commit bcfae08c0b (the one before 5d57087e31) the generated assemble for this file is only 135297 lines of code. Ignoring the stage1 compiler and looking at compiling `compiler/cmm/PprC.hs` with ghc-7.8.4 I see: {{{ revision wc -l PprC.s lwz_count stw_count --------------------------------------------------------------------- commit bcfae08c0b 135297 27751 30921 HEAD (c8d438fb02) 279333 70407 77666 }}} where {{{ lwz_count = grep lwz PprC.s | wc -l stw_count = grep stw PprC.s | wc -l }}} Just out of curiosity I decided to do the same test on x86_64/linux and found: {{{ revision wc -l PprC.s --------------------------------- commit bcfae08c0b 119246 HEAD (c8d438fb02) 246768 }}} a near doubling of the code size. Is it possible we are inlining something we shouldn't? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7830#comment:28 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
