Subject: Makefile.target: support per-target coverage reports
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=90e671a9b2a92ec80d671c249f6bdb876bf37d5f;p=qemu.git

Makefile.target: support per-target coverage reports

Add support for generating a single targets coverage report. Execute:

  make coverage-report

In the target build directory. This coverage report only cares about
target specific blobs so only searches the target build subdirectory.
