| This file describes the directory layout of the PNaCl toolchain. |
| |
| The most important thing is the user-facing toolchain programs, including |
| pnacl-clang, pnacl-clang++, pnacl-translate, etc. These are located in |
| the bin/ directory. The location (and existence) of everything else is subject |
| to change. |
| |
| bin/ |
| User-facing PNaCl toolchain programs (pnacl-clang, pnacl-translate, etc; |
| currently these are OS-specific wrapper scripts). |
| Standard LLVM tools such as llvm-nm, opt etc** |
| Nonstandard LLVM tools such as pnacl-llc** |
| Standard GNU binutils ELF tools |
| include/ |
| Headers for linking against our build of LLVM** |
| lib/ |
| Host libraries used by our build of LLVM** |
| le32-nacl/ |
| Bitcode libraries and headers for building PNaCl modules |
| translator/ |
| Native NaCl object files and/or libraries linked into nexes after |
| offline translation. |
| |
| **These are not generally needed directly by developers of PNaCl modules |
| in Chrome, but may be useful for others, e.g. those who want to build tools |
| which target PNaCl as a platform |
| |
| There are currently two different versions of the PNaCl toolchain: (1) the |
| legacy Python-based toolchain driver which uses the pnacl- prefix for the |
| individual tool names; and (2) the experimental native PNaCl Clang toolchain |
| driver which uses the le32-nacl- prefix. |
