2 * README.android describes in high-level the LLVM changes that we cannot push
3 * upstream to the llvm.org repository:
4 * - Changes due to Android's build system.
5 * - Changes due to Android's toolchain.
6 * - Changes due to the limitations in Android-based consumer electronics.
8 * Some of them are to-dos. If and when they are done, there will no longer be
9 * merge conflicts with upstream on those parts.
11 * The file contains useful hints when we try to resolve future 3-way merge
15 * We add 40+ Android's *.mk files that are specific to Android's build system.
17 * All the configuration files because we don't have configure/make/make-install
19 * Changes for enabling both host and device builds.
21 * All the tblgen work to enable Android to build a generator-generator binary
22 and then run it in the middle of Android build process.
24 * Explicitly include <cctype> header since is*() are not builtin functions in
27 * Code changes to make Android's toolchain stop outputting warnings. (This part
28 should be pushed upstream eventually.)
30 * lib/Target/{X86,ARM}/AsmPrinter/{X86,ARM}AsmPrinter.cpp
31 Move from lib/Target/{X86,ARM}/{X86,ARM}AsmPrinter.cpp.
32 AsmPrinter is only needed in Android when disassembly functionality
33 is desired to be included.
35 * Our ARM code generation fixes that upstream hasn't accepted yet. (This
36 conflict will be resolved eventually, but there will always be time lag.)
38 * Assorted size optimizations because Android-based consumer electronics
