[LLVMdev] lli supports different targets than llc?
Hi, Is it normal/expected for `llc` to support a different set of targets than `lli`? I have a hello.ll on which this works: $ llc -mtriple=armv7a-linux-gnueabihf hello.ll # OK, generates hello.s But this doesn't: $ lli -mtriple=armv7a-linux-gnueabihf hello.ll # lli: error creating EE: No available targets are compatible with this triple, see -version for the available targets. I'm using LLVM from the git mirror: $ lli -version LLVM (http://llvm.org/): LLVM version 3.7.0svn Optimized build. Built Jun 19 2015 (17:35:44). Default target: x86_64-unknown-linux-gnu Host CPU: broadwell I thought they would both support the same targets... Why isn't that the case? Thanks, Débora. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20150723/c64a33d6/attachment.html>

s/pretty much/definitely/ Even then, “works” is too strong a word.
