README.android revision 56e9baf7b6e7745a16b1b114f784027428f21d4b 
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* For Honeycomb: Synced to upstream r112344.
16* For Honeycomb MR1: Synced to upstream r119309
17* For Honeycomb MR2: Synced to upstream r119309
18* For Ice Cream Sandwich: Synced to upstream r133240
19* Most recent update: From r129128 to 133240
20
21* We add 40+ Android's *.mk files that are specific to Android's build system.
22
23* All the configuration files because we don't have configure/make/make-install
24
25* Changes for enabling both host and device builds.
26
27* All the tblgen work to enable Android to build a generator-generator binary
28  and then run it in the middle of Android build process.
29
30* Explicitly include <cctype> header since is*() are not builtin functions in
31Android toolchain.
32
33* Code changes to make Android's toolchain stop outputting warnings. (This part
34  should be pushed upstream eventually.)
35
36* lib/Target/{X86,ARM}/AsmPrinter/{X86,ARM}AsmPrinter.cpp
37   Move from lib/Target/{X86,ARM}/{X86,ARM}AsmPrinter.cpp.
38   AsmPrinter is only needed in Android when disassembly functionality
39      is desired to be included.
40
41* Our ARM code generation fixes that upstream hasn't accepted yet. (This
42  conflict will be resolved eventually, but there will always be time lag.)
43
44* Assorted size optimizations because Android-based consumer electronics
45  need them.
