I'm getting testsuite failures like this on Windows <no location info>: Warning: Couldn't figure out LLVM version! Make sure you have installed LLVM Fair enough, but shouldn't 'configure' find out if I have LLVM. And if I don't, shouldn't the tests be disabled? Do we have instructions for installing LLVM on Windows? Simon

'configure' could play a role but doesn't at the moment as we always compile the LLVM backend and it dynamically supports a few different LLVM versions. So there has been nothing to decide at compile time. A patch was added a while back to allow 'configure' to specify where to find the llvm binaries instead of just expecting them on the PATH but that is all for now. An extremely minimal guide exists in the userguide: http://www.haskell.org/ghc/docs/latest/html/users_guide/code-generators.html... We simply point you to the download page for LLVM. http://llvm.org/releases/download.html#3.2 I haven't tried on Windows for a little while but historically it was very easy, just unzip the files and make sure the binaries are in your PATH. More detailed installation instructions would be worthwhile though. On 15 January 2013 04:56, Simon Peyton-Jones wrote:

Fair enough, but shouldn’t ‘configure’ find out if I have LLVM. And if I don’t, shouldn’t the tests be disabled?

The 'llvm' way is supposed to be disabled in the testsuite if LLVM is not found. Here is the code from testsuite/mk/test.mk: ifneq "$(shell $(SHELL) -c 'llc --version | grep version' 2> /dev/null)" "" RUNTEST_OPTS += -e ghc_with_llvm=1 else RUNTEST_OPTS += -e ghc_with_llvm=0 endif Maybe this isn't working? Or maybe you have llc on your path, but there's something wrong with it? Which test is failing specifically? Cheers, Simon

If you try compiling something with the LLVM backend but with '-v2' enabled, it should tell you why it can't figure out the LLVM version in use. I'll try to test myself but it may be a little while before I have a windows box setup for that. On 16 January 2013 19:43, Simon Peyton-Jones wrote:

Oh and LLVM 3.1 is a supported version so it should be fine. LLVM 3.2 (released last month) isn't yet supported. On 16 January 2013 19:43, Simon Peyton-Jones wrote:

Remember getting these errors, and I remember fixing them by having llc-3.0 and opt-3.0 in the path. On 01/14/2013 06:56 PM, Simon Peyton-Jones wrote:

My guess is llc doesn't like the arguments being passed to it. Try running llc as follows: $ llc -version (one dash, not two). That works fine on linux and osx. Does it not work on windows? Cheers, David On 16 January 2013 21:30, Simon Peyton-Jones wrote:

I have no idea what "invalid argument" means. I can do further experiments if told what to try.

It's fine. llc -version (one dash) works ok. see below bash-3.1$ llc -version LLVM (http://llvm.org/): LLVM version 3.1 Optimized build with assertions. Built May 22 2012 (00:18:58).

OK I'll try to get a windows machine up and fix this in the next week or so. On 16 January 2013 23:29, Simon Peyton-Jones wrote:
