arm: Make sel build with clang's built-in assembler.

clang's integrated assembler only supports UAL, where sp is spelled
sp and not %sp. Fixes the following error when building with clang's
integrated assembler enabled:

../../native_client/src/trusted/service_runtime/linux/arm/sel_segments.c:13:7: error: unexpected token in operand
  asm("mov %0, %%sp" : "=r" (sp));
      ^
<inline asm>:1:10: note: instantiated into assembly here
        mov r0, %sp
                ^
1 error generated.

Native Client

Welcome to Native Client. For the latest information about Native Client, see the Native Client project page.

Documentation

Most of the Native Client project documentation is available online:

Directory structure

The following list describes major files and directories that you‘ll see in your working copy of the repository, including some directories that don’t exist until you've built Native Client. Paths are relative to the native_client directory.

  • COPYING NOTICE README.md RELEASE_NOTES documentation/: Documentation, release, and license information.

  • SConstruct scons.bat scons scons-out/ site_scons/: Build-related files. The scons.bat and scons files, with data from SConstruct, let you build Native Client and its tests. The scons-out and site-scons directories don‘t exist in the git repository; they’re created when Native Client is built. The scons-out/*/staging directories contain files, such as the Native Client plug-in and compiled examples, that let you use and test Native Client.

  • src/: Core source code for Native Client.

  • src/include/: Header files that are missing from some platforms and are used by more than one major part of Native Client

  • src/shared/: Source code that's used by both trusted code (such as the service runtime) and untrusted code (such as Native Client modules)

  • src/third_party: Other people's source code

  • src/trusted/: Source code that's used only by trusted code

  • src/untrusted/: Source code that's used only by untrusted code

  • tests/common/: Source code for examples and tests.

  • ../third_party/: Third-party source code and binaries that aren't part of the service runtime. When built, the Native Client toolchain is in src/third_party/nacl_sdk/.

  • tools/: Utilities such as the plug-in installer.
