#10170: Find versioned versions of LLVM tools -------------------------------------+------------------------------------- Reporter: erikd | Owner: erikd Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler (LLVM) | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by rwbarton):
More importantly configure should fail if whatever version of llc it finds isn't the currently blessed version.
Right.
Yes, it should look for a versioned `/usr/lib/llc-X.Y` but also accept `/usr/lib/llvm-3.6/bin/llc`
Let me rephrase what I meant. Hard-coding knowledge of the directory `/usr/lib/llvm-3.6/bin` into ghc's autoconf is wrong because (in my estimation) the fact that `llc-3.6` is a symlink to `/usr/lib/llvm-3.6/bin/llc` is an implementation detail of the Debian `llvm-3.6` package and the executable may be (and is) located elsewhere on other distributions. The public interface of `llvm-3.6` (on Debian and hopefully on other distributions) is that it provides `llc-3.6` on the standard `$PATH`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10170#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
