This works the same way as LLVM_PARALLEL_COMPILE_JOBS except that it is specific to the flang source rather than for the whole project. Configuring with -DFLANG_PARALLEL_COMPILE_JOBS=1 would mean that there would only ever be one flang source being compiled at a time. Some of the flang sources require large amounts of memory to compile, so this option can be used to avoid OOM erros when compiling those files while still allowing the rest of the project to compile using the maximum number of jobs. --------- Co-authored-by: Nikita Popov <github@npopov.com>
