Problem for me was that e.g. callingccov-capture-TARGET was doing much more than the name was telling, e.g. it was cleaning all coverage data collected until then. Alsoccov was doing the same for all targets.

I draw the targets dependencies tree (- - is a target dependency,+ is extra action done by the target):

- ccov  - ccov-TARGET    - ccov-capture-TARGET      - ccov-preprocessing        - ccov-clean          + remove *.list files        + make cov directory      + remove coverage info      + zero counters      + run TARGET      + generate coverage info    + gen html

So callingccov was going down the tree and removing and regenerating everything. So any extra changes done in the meantime like manually called targets with special options were lost.

So I change the hierarchy into this ((**) denotes new targets):

- ccov-html (**)  - ccov-html-TARGET- ccov:  - ccov-clean-TARGET (**)    + remove coverage info    + zero counters  - ccov-run-TARGET    - ccov-preprocessing      ...    + run TARGET  - ccov-html-TARGET (**)    - ccov-capture-TARGET      + generate coverage info    + gen html

So nowccov-clean-TARGET just clean,ccov-capture-TARGET just captures the data, butccov does all of them so it is backward compatible. The new targetccov-html-TARGET captures the data and generates html. Here I made exception that-html calls-capture because this makes sense. Theccov-clean-TARGET is new and it sole purpose is to remove files. Task which was previously done byccov-capture-TARGET.

Similar change I made forccov-all-* targets. Old scheme was:

- ccov-all  - ccov-all-capture    - ccov-preprocessing    - ccov-all-preprocessing    + remove coverage info    + zero counters    + generate coverage info  + gen html

new scheme is

- ccov-all  - ccov-preprocessing  - ccov-all-processing  - ccov-all-clean (**)    + remove coverage info    + zero counters  - ccov-all-html (**)    - ccov-all-capture      + generate coverage info    + gen html

Now I can just run my targets in a custom way and callmake ccov-all-html to collect data. Previously it was not possible.
