[Mono-dev] mono 3.0, llvm, sgen

[Sebastian Good]

Thanks! I built from master via git (7a59454e4145af107520c8fc7d9a85ffa274f980) and mono is running including all our tests using llvm. The spurious command-line logs continue to be printed to stdout, but appear to be harmless.

<premain>: CommandLine Error: Argument 'print-machineinstrs' defined more than once!
<premain>: CommandLine Error: Argument 'misched' defined more than once!
-simplifycfg: CommandLine Error: Argument 'print-machineinstrs' defined more than once!
-simplifycfg: CommandLine Error: Argument 'misched' defined more than once!

Thanks so much for your help.

I configured both builds to install in a common place. ("/mono" in the instructions). This common path's bin is in my path, and its lib is in my LD_LIBRARY_PATH.

It makes me wonder if I've built the wrong version of llvm, or somehow gotten my link paths wrong either during configure or runtime. As far as I can tell the <premain> and -simplifycfg "errors" are from LLVM, but I'm not sure what to make of those, either. I'd appreciate any help!
