## Installation of LLVM 5.0
|
|
|
|
############ Extract LLVM, CLANG and other from git in current directory.
|
|
############
|
|
############ Question:
|
|
############ Do we need the Clang sources for F18?
|
|
############ Probably not but its nice to have the Clang source as
|
|
############ example during development.
|
|
############ Also, we need cland-format.

## Installation of Flang

######### Add $PREFIX/bin to PATH so that cmake finds llvm-config

export "PATH=$PREFIX/bin:$PATH"

######## Get Flang sources
