The most time-consuming part is invoking "ninja -t compdb", and there is no need to repeat that for every mode. Signed-off-by: Michael Livshin <michael.livshin@scylladb.com> Closes #10733

# Called by configure.py to merge several compdbs into one, so your
|
|
# favourite compatible code indexer can present you with a relevant
|
|
# maximally-complete unified index.
|
|
#
|
|
|
|
# Usage: merge-compdb.py build/{debug,release,dev,sanitize} [input...]
|
|
#
|
|
# Glue inputs, which must be compdb ("compile_command.json") files,
|
|
# together, filtering out anything that is not indexable or not built
|
|
# under the given prefix, and write the result to stdout.
|
|
#
|
|
# An input is either a file name or "-" for stdin.
|
|
#
|
|
# configure.py calls this with "-" for the ninja-generated scylla
|
|
# compdb and mode-specific seastar & abseil compdbs.
