#14261: ghc stopped recognizing some arm triplets that used to work: Failed to lookup the datalayout for armv7a-hardfloat-linux-gnueabi; available targets: -------------------------------------+------------------------------------- Reporter: slyfox | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by angerman): I believe the error message could be better :-( Targets are not hardcoded into GHC anymore, they are read from the `llvm- targets` file, at the top level. (It is also copied during install/...), which is read by ghc at runtime, and thus changes to it are directly reflected without recompilation. The `llvm-targets` file can be generated via the `utils/llvm-targets/gen- data-layout.sh` script. That being said, I am a bit confused about the `armv7a-hardfloat-linux- gnueabi` target. Shouldn't that be `armv7-unknown-linux-gnueabihf`? Should we use Autoconf triple canonicalization here? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14261#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
