Pork
,no edit summary
=== Requirements ===
* GCC 3.4.x or older that can successfully build Mozilla. 64bit Ubuntu, 32bit RHEL/CentOS are known to work. 32bit Ubuntu/Debian feature a linker bug that prevents Mozilla from building with gcc 3.4.6.Note: Recent work on Pork's Elsa allows it to be used with GCC 4.2
* MCPP is required for refactoring tools
* [[SpiderMonkey]] is required by [[DeHydra]]
=== Pork Tools ===
Pork is broken down into tools that focus on a specific tasks. The tools can rarely be combined and thus should be applied incrementally.
* [[Outparamdel]] rewrites code using outparameters to utilize the return value instead. [http://blog.mozilla.com/tglek/2007/08/06/outparams-take-2/ Blog entry]
* [[PorkBarrel]] is a multiplexer(ala make -j) for the pork tools. It can combine patch output for patch-producing tools and save per-file output for DeHydra. The repository also contains a frontend to do nightly runs of prcheck.
* [[Dehydra GCC]] a static analysis plugin for GCC.
=== Differences from Mainstream ===
** Expression AST nodes were modified to include end-of-node info + associated bugfixes
** Elsa has been extended to support MCPP's macro-undo(-K) mode. Additional APIs were added to convert post-preprocessing source coordinates into pre-preprocessing ones
** Elsa has received bugfixes to work with recent GCC (4.2) headers
