Compact MinGW package.
/cc @charmainel @bhenden @kusma
These two changes reduce the size of the resulting piglit MinGW package with MinSizeRel
from 745 Mb to 114 Mb. This is achieve through 3 things:
- not statically linking libGCC/libstdc++
- stripping debugging symbols when packaging
- using 7-Zip instead of ZIP.
Of course, much more reduction would be possible if piglit util libraries were built as DLLs, but that's a much tougher nut to crack.
The hope here is can eventually start storing the package as a Gitlab artifact for certain builds (e.g, nightly/weekly builds from master, or even just manual -- whenever a new piglit deliverable is needed).
