#10170: Find versioned versions of LLVM tools -------------------------------------+------------------------------------- Reporter: erikd | Owner: erikd Type: bug | Status: closed Priority: normal | Milestone: 8.0.1 Component: Compiler (LLVM) | Version: 7.11 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D745 Wiki Page: | -------------------------------------+------------------------------------- Comment (by jberryman): Hi, this seems to have regressed. Should I open a new ticket? I'd like for ghc to look for versioned llvm executables in the PATH and prefer those over the unversioned names (if they exist). If #10074 is stalled this change seems sufficient to me. As it stands using multiple ghc versions with fllvm side by side is pretty inconvenient (or else I haven't figured out the trick). {{{ $ echo $PATH /home/me/Code/NOT_MY_CODE/spack/bin:/usr/lib/llvm-6.0/bin:/home/me/.cargo/bin:/usr/local/go/bin:/home/me/.rbenv/shims:/home/me/.rbenv/bin:/home/me/.play-2.2.2:/home/me/.node/bin:/usr/local/node/bin:/home/me/.local/bin:/home/me/.cabal/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin:/home/me/.gem/ruby/2.2.0/bin:/home/me/.go/bin $ which opt /usr/lib/llvm-6.0/bin/opt $ ghc --make -fforce-recomp -fllvm hello.hs -o hello_llvm [1 of 1] Compiling Main ( hello.hs, hello.o ) Linking hello_llvm ... $ export PATH=/home/me/.cargo/bin:/usr/local/go/bin:/home/me/.rbenv/shims:/home/me/.rbenv/bin:/home/me/.play-2.2.2:/home/me/.node/bin:/usr/local/node/bin:/home/me/.local/bin:/home/me/.cabal/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin:/home/me/.gem/ruby/2.2.0/bin:/home/me/.go/bin $ which opt opt not found $ which opt-6.0 1 ↵ /usr/bin/opt-6.0 $ ghc --make -fforce-recomp -fllvm hello.hs -o hello_llvm [1 of 1] Compiling Main ( hello.hs, hello.o ) <no location info>: error: Warning: Couldn't figure out LLVM version!
