Subject: tests : add --list-ops and --show-coverage options (#15745)
X-Git-Tag: upstream/0.0.6527~136
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=3a550b5ca4565c9e28f63880d47840feb27d0ff6;p=pkg%2Fggml%2Fsources%2Fllama.cpp

tests : add --list-ops and --show-coverage options (#15745)

This commit adds two new command-line options to the
test-backend-ops.cpp that allow users to list all available GGML
operations and to show test coverage of these operations.

The motivation for this is that it can be useful to quickly see which
operations are currently covered by tests and which are not. Also it
migth be useful when using the `support` mode.
