#14966: Symbols in -ddump-asm output don't match real output -------------------------------------+------------------------------------- Reporter: terrorjack | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.5 (NCG) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Symbols in the .s files generated by NCG are properly Z-encoded, but they aren't in the -ddump-asm output. One trivial example: {{{ {-# OPTIONS_GHC -ddump-to-file -ddump-asm -keep-s-files #-} module Fact where fact :: Int -> Int fact 0 = 1 fact n = n * fact (n - 1) }}} The contents of Fact.s: {{{ .section .rdata .align 1 .align 1 r23Y_bytes: .asciz "main" .section .data .align 8 .align 1 r24i_closure: .quad ghczmprim_GHCziTypes_TrNameS_con_info .quad r23Y_bytes ... }}} The contents of Fact.dump-asm: {{{ ==================== Asm code ==================== 2018-03-23 14:00:27.8082773 UTC .section .rdata .align 1 .align 1 $trModule1_r23Y_bytes: .asciz "main" ==================== Asm code ==================== 2018-03-23 14:00:27.8172758 UTC .section .data .align 8 .align 1 $trModule2_r24i_closure: .quad GHC.Types.TrNameS_con_info .quad $trModule1_r23Y_bytes ... }}} This is confirmed on multiple GHC versions, up to 8.5. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14966 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
