[llvm-dev] Unable to get started with LLI and LLC

[Jagrat Patkar via llvm-dev]

Executed the commands as suggested, it did build lli and llc and gave the
following output

*[2302/2302] Linking CXX executable bin/llc*

but when I type lli or llc in the command line still it giving me *command
not found error*
