| 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. |
| 13 | */ |
| 14 | |
| 15 | * We add 40+ Android's *.mk files that are specific to Android's build system. |
| 16 | |
| 17 | * All the configuration files because we don't have configure/make/make-install |
| 18 | |
| 19 | * Changes for enabling both host and device builds. |
| 20 | |
| 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. |
| 23 | |
| 24 | * Explicitly include <cctype> header since is*() are not builtin functions in |
| 25 | Android toolchain. |
| 26 | |
| 27 | * Code changes to make Android's toolchain stop outputting warnings. (This part |
| 28 | should be pushed upstream eventually.) |
| 29 | |
| 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. |
| 34 | |
| 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.) |
| 37 | |
| 38 | * Assorted size optimizations because Android-based consumer electronics |
| 39 | need them. |
