[llvm-dev] Distributing llc and opt with own package?

[Matthias Braun via llvm-dev]

Just a word of warning:

llc and opt are primarily developed as debugging tools to support LLVM testing. They are not intended to be shipped or used as code generators for frontends. They do often work in these settings but you may hit rough edges that nobody will care to fix and the behavior or commandline interface may change every release... A more stable alternative is usually to feed .ir/.bc files to clang or better link to the llvm libraries and generate the code from there.
