patch 9.0.2028: confusing build dependencies Commit: https://github.com/vim/vim/commit/5d03525cdef5db1b1cedfa26c6f8a21aaa207ec0 Author: Yee Cheng Chin <ychin.git@gmail.com> Date: Sun Oct 15 09:50:53 2023 +0200 patch 9.0.2028: confusing build dependencies Problem: confusing build dependencies Solution: clean them up, make them parallelizable Separate vim binary and unittest dependencies, make them parallelizable Clean up make dependencies so Vim and unit test binaries only depend on the object files they need. This fixes an existing issue where after running unit tests, the Vim binary would be invalidated, which results in it having to be linked again when running script tests, even though Vim was already previously built. Make link.sh (script we use to link those binaries) generate namespaced temporary files for each app to avoid them colliding with each other. This allows `unittesttargets` to be built in parallel. These fixes are useful when using link-time-optimization as the link phase could now take minutes rather than a few seconds. closes: #13344 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
