A committer can submit his or her own patches or patches from others. + +This privilege is granted with some expectation of responsibility: committers are people who care about the V8 project and want to help meet its goals. A committer is not just someone who can make changes, but someone who has demonstrated his or her ability to collaborate with the team, get the most knowledgeable people to review code, contribute high-quality code, and follow through to fix issues (in code or tests). + +A committer is a contributor to the V8 projects' success and a citizen helping the projects succeed. See V8CommittersResponsibility. + +## How do I become a committer? + +In a nutshell, contribute 20 non-trivial patches and get at least three different people to review them (you'll need three people to support you). Then ask someone to nominate you. You're demonstrating your: + + * commitment to the project (20 good patches requires a lot of your valuable time), + * ability to collaborate with the team, + * understanding of how the team works (policies, processes for testing and code review, etc), + * understanding of the projects' code base and coding style, and + * ability to write good code (last but certainly not least) + +A current committer nominates you by sending email to v8-committers@googlegroups.com containing: + + * your first and last name + * your Google Code email address + * an explanation of why you should be a committer, + * embedded list of links to revisions (about top 10) containing your patches + +Two other committers need to second your nomination. If no one objects in 5 working days (U.S.), you're a committer. If anyone objects or wants more information, the committers discuss and usually come to a consensus (within the 5 working days). If issues cannot be resolved, there's a vote among current committers. + +Once you get approval from the existing committers, we'll send you instructions for write access to SVN or Git. You'll also be added to v8-committers@googlegroups.com. + +In the worst case, this can drag out for two weeks. Keep writing patches!

So your basic command for building is: +``` +make ia32.release +``` + +or analogously for the other architectures and modes. You can build both debug and release binaries with just one command: +``` +make ia32 +``` + +To automatically build in release mode for the host architecture: +``` +make native +``` + +You can also can build all architectures in a given mode at once: +``` +make release +``` + +Or everything: +``` +make +``` + +#### Optional parameters + + * `-j` specifies the number of parallel build processes. Set it (roughly) to the number of CPU cores your machine has. The GYP/make based V8 build also supports distcc, so you can compile with `-j100` or so, provided you have enough machines around. + + * `OUTDIR=foo` specifies where the compiled binaries go. It defaults to `./out/`. In this directory, a subdirectory will be created for each architecture and mode. You will find the d8 shell's binary in `foo/ia32.release/d8`, for example. + + * `library=shared` or `component=shared_library` (the two are completely equivalent) builds V8 as a shared library (`libv8.so`). + + * `soname_version=1.2.3` is only relevant for shared library builds and configures the SONAME of the library. Both the SONAME and the filename of the library will be `libv8.so.1.2.3` if you specify this. Due to a peculiarity in GYP, if you specify a custom SONAME, the library's path will no longer be encoded in the binaries, so you'll have to run d8 as follows: +``` +LD_LIBRARY_PATH=out/ia32.release/lib.target out/ia32.release/d8 +``` + + * `console=readline` enables readline support for the d8 shell. You need readline development headers for this (`libreadline-dev` on Ubuntu). + + * `disassembler=on` enables the disassembler for release mode binaries (it's always enabled for debug binaries). This is useful if you want to inspect generated machine code. + + * `snapshot=off` disables building with a heap snapshot. Compiling will be a little faster, but V8’s start up will be slightly slower. + + * `gdbjit=on` enables GDB JIT support. + + * `liveobjectlist=on` enables the Live Object List feature. + + * `vfp3=off` is only relevant for ARM builds with snapshot and disables the use of VFP3 instructions in the snapshot. + + * `debuggersupport=off` disables the javascript debugger. + + * `werror=no` omits the -Werror flag. This is especially useful for not officially supported C++ compilers (e.g. newer versions of the GCC) so that compile warnings are ignored. + + * `strictaliasing=off` passes the -fno-strict-aliasing flag to GCC. This may help to work around build failures on officially unsupported platforms and/or GCC versions. + + * `regexp=interpreted` chooses the interpreted mode of the irregexp regular expression engine instead of the native code mode. + + * `hardfp=on` creates "hardfp" binaries on ARM. + +### Ninja + +To build d8: +``` +export GYP_GENERATORS=ninja +build/gyp_v8 +ninja -C out/Debug d8 +``` + +Specify `out/Release` for a release build. I recommend setting up an alias so that you don't need to type out that build directory path. + +If you want to build all targets, use `ninja -C out/Debug all`. It's faster to build only the target you're working on, like `d8` or `unittests`. + +Note: You need to set `v8_target_arch` if you want a non-native build, i.e. either +``` +export GYP_DEFINES="v8_target_arch=arm" +build/gyp_v8 ... +``` +or +``` +build/gyp_v8 -Dv8_target_arch=arm ... +``` + + +#### Using goma (Googlers only) + +To use goma you need to set the `use_goma` gyp define, either by passing it to `gyp_v8`, i.e. +``` +build/gyp_v8 -Duse_goma=1 +``` +or by setting the environment variable `$GYP_DEFINES` appropriately: +``` +export GYP_DEFINES="use_goma=1" +``` +Note: You may need to also set `gomadir` to point to the directory where you installed goma, if it's not in the default location. + +If you are using goma, you'll also want to bump the job limit, i.e. +``` +ninja -j 100 -C out/Debug d8 +``` + + +### Cross-compiling + +Similar to building with Clang, you can also use a cross-compiler. Just export your toolchain (`CXX`/`LINK` environment variables should be enough) and compile. For example: +``` +export CXX=/path/to/cross-compile-g++ +export LINK=/path/to/cross-compile-g++ +make arm.release +``` + + +### Xcode + +From the root of your V8 checkout, run either of: +``` +build/gyp_v8 -Dtarget_arch=ia32 +build/gyp_v8 -Dtarget_arch=x64 +``` + +This will generate Xcode project files in `build/` that you can then either open with Xcode or compile directly from the command line: +``` +xcodebuild -project build/all.xcodeproj -configuration Release +xcodebuild -project build/all.xcodeproj +``` + +Note: If you have configured your `GYP_GENERATORS` environment variable, either unset it, or set it to `xcode` for this to work. + + +#### Custom build settings + +You can export the `GYP_DEFINES` environment variable in your shell to configure custom build options. The syntax is `GYP_DEFINES="-Dvariable1=value1 -Dvariable2=value2"` and so on for as many variables as you wish. Possibly interesting options include: + * `-Dcomponent=shared_library` (see `library=shared` in the [GCC + make](#Optional_parameters.md) section above) + * `-Dconsole=readline` (see `console=readline`) + * `-Dv8_enable_disassembler=1` (see `disassembler=on`) + * `-Dv8_use_snapshot='false'` (see `snapshot=off`) + * `-Dv8_enable_gdbjit=1` (see `gdbjit=on`) + * `-Dv8_use_liveobjectlist=true` (see `liveobjectlist=on`) + + +### Visual Studio + +You need Visual Studio 2013, older versions might still work at the moment, but this will probably change soon because we intend to use C++11 features. + +#### Prerequisites + +After you created [checkout of V8](using_git.md), all dependencies will be already installed. + +If you are getting errors during build mentioning that 'python' could not be found, add the 'python.exe' to PATH. + +If you have Visual Studio 2013 and 2015 installed side-by-side and set the environment variable GYP\_MSVS\_VERSION to '2013'. In that case the right project files are going to be created. + +#### Building + * If you use the command prompt: + 1.

 + +--- + + +# Using Sourcery G++ Lite + +The Sourcery G++ Lite cross compiler suite is a free version of Sourcery G++ from [CodeSourcery](http://www.codesourcery.com). There is a page for the [GNU Toolchain for ARM Processors](http://www.codesourcery.com/sgpp/lite/arm). Determine the version you need for your host/target combination. + +The following instructions uses [2009q1-203 for ARM GNU/Linux](http://www.codesourcery.com/sgpp/lite/arm/portal/release858), and if using a different version please change the URLs and `TOOL_PREFIX` below accordingly. + +## Installing on host and target + +The simplest way of setting this up is to install the full Sourcery G++ Lite package on both the host and target at the same location. This will ensure that all the libraries required are available on both sides. If you want to use the default libraries on the host there is no need the install anything on the target. + +The following script will install in `/opt/codesourcery`: + +``` +#!/bin/sh + +sudo mkdir /opt/codesourcery +cd /opt/codesourcery +sudo chown $USERNAME . +chmod g+ws . +umask 2 +wget http://www.codesourcery.com/sgpp/lite/arm/portal/package4571/public/arm-none-linux-gnueabi/arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 +tar -xvf arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 +``` + + +## Building using scons without snapshot + +The simplest way to build is without snapshot, as that does no involve using the simulator to generate the snapshot. The following script will build the sample shell without snapshot for ARM v7. + +``` +#!/bin/sh + +export TOOL_PREFIX=/opt/codesourcery/arm-2009q1/bin/arm-none-linux-gnueabi +export CXX=$TOOL_PREFIX-g++ +export AR=$TOOL_PREFIX-ar +export RANLIB=$TOOL_PREFIX-ranlib +export CC=$TOOL_PREFIX-gcc +export LD=$TOOL_PREFIX-ld + +export CCFLAGS="-march=armv7-a -mtune=cortex-a8 -mfpu=vfp" +export ARM_TARGET_LIB=/opt/codesourcery/arm-2009q1/arm-none-linux-gnueabi/libc + +scons wordsize=32 snapshot=off arch=arm sample=shell +``` + +If the processor is not Cortex A8 or does not have VFP enabled the `-mtune=cortex-a8` and `-mfpu=vfp` part of `CCFLAGS` needs to be changed accordingly. By default the V8 SCons build adds `-mfloat-abi=softfp`. + +If using the default libraries on the target just leave out the setting of `ARM_TARGET_LIB` and if the target libraies are in a different location ARM\_TARGET\_LIB` needs to be adjusted accordingly. + +The default for Sourcery G++ Lite is ARM v5te with software floating point emulation, so if testing building for ARM v5te the setting of `CCFLAGS` and `ARM_TARGET_LIB` should be changed to: + +``` +CCFLAGS="" +ARM_TARGET_LIB=/opt/codesourcery/arm-2009q1/arm-none-linux-gnueabi/libc + +scons armeabi=soft ... +``` + +Relying on defaults in the tool chain might lead to surprises, so for ARM v5te with software floating point emulation the following is more explicit: + +``` +CCFLAGS="-march=armv5te" +ARM_TARGET_LIB=/opt/codesourcery/arm-2009q1/arm-none-linux-gnueabi/libc + +scons armeabi=soft ... +``` + +If the target has an VFP unit use the following: + +``` +CCFLAGS="-mfpu=vfpv3" +ARM_TARGET_LIB=/opt/codesourcery/arm-2009q1/arm-none-linux-gnueabi/libc +``` + +To allow G++ to use Thumb2 instructions and the VFP unit when compiling the C/C++ code use: + +``` +CCFLAGS="-mthumb -mfpu=vfpv3" +ARM_TARGET_LIB=/opt/codesourcery/arm-2009q1/arm-none-linux-gnueabi/libc/thumb2 +``` + +_Note:_ V8 will not use Thumb2 instructions in its generated code it always uses the full ARM instruction set. + +For other ARM versions please check the Sourcery G++ Lite documentation. + +As mentioned above the default for Sourcery G++ Lite used here is ARM v5te with software floating point emulation. However beware that this default might change between versions and that there is no unique defaults for ARM tool chains in general, so always passing `-march` and possibly `-mfpu` is recommended. Passing `-mfloat-abi` is not required as this is controlled by the SCons option `armeabi`. + +## Building using scons with snapshot + +When building with snapshot the simulator is used to build the snapshot on the host and then building for the target with that snapshot. The following script will accomplish that (using both Thumb2 and VFP instructions): + +``` +#!/bin/sh + +V8DIR=.. + +cd host + +scons -Y$V8DIR simulator=arm snapshot=on +mv obj/release/snapshot.cc $V8DIR/src/snapshot.cc + +cd .. + +export TOOL_PREFIX=/opt/codesourcery/arm-2010.09-103/bin/arm-none-linux-gnueabi +export CXX=$TOOL_PREFIX-g++ +export AR=$TOOL_PREFIX-ar +export RANLIB=$TOOL_PREFIX-ranlib +export CC=$TOOL_PREFIX-gcc +export LD=$TOOL_PREFIX-ld + +export CCFLAGS="-mthumb -march=armv7-a -mfpu=vfpv3" +export ARM_TARGET_LIB=/opt/codesourcery/arm-2010.09-103/arm-none-linux-gnueabi/libc/thumb2 + +cd target + +scons -Y$V8DIR wordsize=32 snapshot=nobuild arch=armsample=shell +rm $V8DIR/src/snapshot.cc + +cd .. +``` + +This script required the two subdirectories `host` and `target`. V8 is first build for the host with the ARM simulator which supports running ARM code on the host. This is used to build a snapshot file which is then used for the actual cross compilation of V8. + +## Building for target which supports unaligned access + +The default when building V8 for an ARM target (either cross compiling or compiling on an ARM machine) is to disable unaligned memory access. However in some situations (most noticeably handling of regular expressions) performance will be better if unaligned memory access is used on processors which supports it. To enable unaligned memory access set `unalignedaccesses` to `on` when building: + +``` +scons unalignedaccesses=on ... +``` + +When running in the simulator the default is to enable unaligned memory access, so to test in the simulator with unaligned memory access disabled set `unalignedaccesses` to `off` when building: + +``` +scons unalignedaccesses=off simulator=arm ... +``` + +## Using V8 with hardfp calling convention + +By default V8 uses the softfp calling convention when calling C functions from generated code. However it is possible to use hardfp as well. To enable this set `armeabi` to `hardfp` when building: + +``` +scons armeabi=hardfp ... +``` + +Passing `armeabi=hardfp` to SCons will automatically set the compiler flag `-mfloat-abi=hardfp`. If using snapshots remember to pass `armeabi=hardfp` when building V8 on the host for generating the snapshot as well. \ No newline at end of file diff --git a/deps/v8/docs/d8_on_android.md b/deps/v8/docs/d8_on_android.md new file mode 100644 index 0000000000..eda6419345 --- /dev/null +++ b/deps/v8/docs/d8_on_android.md @@ -0,0 +1,101 @@ +# Prerequisites + * a Linux/Mac workstation + * v8 r12178 (on Google Code) or later + * an Android emulator or device with matching USB cable + * make sure [building with GYP](http://code.google.com/p/v8-wiki/wiki/BuildingWithGYP) works + + +# Get the code + + * Use the instructions from https://code.google.com/p/v8-wiki/wiki/UsingGit to get the code + * Once you need to add the android dependencies: +``` +v8$ echo "target_os = ['android']" >> ../.gclient && gclient sync --nohooks +``` + * The sync will take a while the first time as it downloads the Android NDK to v8/third\_party + * If you want to use a different NDK, you need to set the gyp variable android\_ndk\_root + + +# Get the Android SDK + * tested version: `r15` + * download the SDK from http://developer.android.com/sdk/index.html + * extract it + * install the "Platform tools" using the SDK manager that you can start by running `tools/android` + * now you have a `platform_tools/adb` binary which will be used later; put it in your `PATH` or remember where it is + + +# Set up your device + * Enable USB debugging (Gingerbread: Settings > Applications > Development > USB debugging; Ice Cream Sandwich: Settings > Developer Options > USB debugging) + * connect your device to your workstation + * make sure `adb devices` shows it; you may have to edit `udev` rules to give yourself proper permissions + * run `adb shell` to get an ssh-like shell on the device.
