We are simplifying the Hotspot build process by standardizing the code
and reducing the number of required tools. As a first step we are
removing the use of the MakeDeps tool and the includeDB files.
This will help new developers get up to speed with the code, which will
benefit both internal developers and the open source community. It will
also make IDE integration simpler.
MakeDeps provided these services:
* Includes between source files
* Platform dispatching
* Precompiled header management
* Makefile rules for source file dependencies
* Source files selection based on compiled target (compiler1, tiered,
* VisualStudio project creation
* Circular dependency detection
To replace MakeDeps we updated all source files with explicit include
statements, include guards and platform dispatching with #ifdefs. We
also updated the makefiles to provide the rest of the MakeDeps services.
Note: this change will update almost all source files and many
makefiles. The top-level make commands have not been changed.
