README.android revision 9c6c99840a16fda86453ed2f65f180ee8fcbcbc6
1/*
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.
7 *
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.
10 *
11 * The file contains useful hints when we try to resolve future 3-way merge
12 * conflicts.

15* Synced to r129128.
16
17* We add 40+ Android's *.mk files that are specific to Android's build system.
18
19* All the configuration files because we don't have configure/make/make-install
20
21* Changes for enabling both host and device builds.
22
23* All the tblgen work to enable Android to build a generator-generator binary
24  and then run it in the middle of Android build process.
25
26* Explicitly include <cctype> header since is*() are not builtin functions in
27Android toolchain.
28
29* Code changes to make Android's toolchain stop outputting warnings. (This part
30  should be pushed upstream eventually.)
31
32* lib/Target/{X86,ARM}/AsmPrinter/{X86,ARM}AsmPrinter.cpp
33   Move from lib/Target/{X86,ARM}/{X86,ARM}AsmPrinter.cpp.
34   AsmPrinter is only needed in Android when disassembly functionality
35      is desired to be included.
36
37* Our ARM code generation fixes that upstream hasn't accepted yet. (This
38  conflict will be resolved eventually, but there will always be time lag.)
39
40* Assorted size optimizations because Android-based consumer electronics
41  need them.
