Perhaps we should be generating those header files in OBJDIR (and use a
move-if-changed
scheme to avoid bumping the date if the contents haven't changed) so that make
can handle
these changes?
Seems reasonable if that change is straightforward, but we could also
just add a special case in tools/build/depend-cleanup.sh to handle
this. depend-cleanup can be fairly liberal, e.g. delete *.def.
Yes, but the problem isn't deleting *.def. Those are static files whose content
changes based on -D flags passed on the command line and you need to delete all
the *.o files that include those .def files. Note that if you switch from
WITHOUT_LLVM_TARGET_ALL to WITH_LLVM_TARGET_ALL or vice versa between builds
you would also hit this issue.
