[Qemu-devel] [PATCH v3 0/2] make: Cleanup and fix of loading of dependency info |

Changes from v2:
Address comment by Paolo Bonzini:
- Store list of generated hex files in a variable and derive from it
list of dependences to be included.
Address comment by Alex Bennee and Michael S. Tsirkin:
- Add a comment about difference between $(@D) and $(*D) in gnu make.
- Better explanation why touching of some *.dsl sources is necessary.
make build can fail when one switches between commits without running
"make clean".
This is caused by loading old *.d dependency info files and is harmful for
autogenerated sources with their own includes. This situation may
significantly slow down the process of git bisect.
These two patches clean things up and fix the issue both for further versions,
and between old and new commits.
This also replaces my previous patch "[PATCH] make: explicit dependencies for
ACPI gen sources".
I've tested the fix by validating that lists included by previous "*.d"
approach and new "patsubst" approach are identical.
Victor Kaplansky (2):
make: fix where dependency *.d are stored.
make: load only required dependency files.
