commit 2d696fc3d02c9e7246f58d4199cb4ec4fd597fd1 Author: Anthony PERARD <anthony.perard@xxxxxxxxxx> AuthorDate: Mon Aug 15 08:55:16 2022 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Mon Aug 15 08:55:16 2022 +0200 tools/fuzz/x86_instruction_emulator: rework makefile Rework dependencies of all objects. We don't need to add dependencies for headers that $(CC) is capable of generating, we only need to include $(DEPS_INCLUDE). Some dependencies are still needed so make knows to generate symlinks for them. We remove the use of "vpath" for cpuid.c. While it works fine for now, when we will convert this makefile to subdirmk, vpath will not be usable. Also, "-iquote" is now needed to build "cpuid.o". Replace "-I." by "-iquote .", so it applies to double-quote includes only. Rather than checking if a symlink exist, always regenerate the symlink. So if the source tree changed location, the symlink is updated. Since we are creating a new .gitignore for the symlink, also move the entry to it.
