== Research PGO-related bugs Project Name ==
On Windows, Mozilla has begun using [https://bugzilla.mozilla.org/show_bug.cgi?id=419893 profile-guided optimization] to make execution of the browser faster (i.e., you run your binary and see how it is likely to run, and optimize for those code paths). Currently, there are parts of the Mozilla source code that have bugs or crash when run in PGO builds. This project will mean trying to isolate these bugs by doing PGO builds of these components, creating test cases, debugging, and hopefully fixing things.Related Bugs
Resources== Project Description == Firefox crashes or experiences bugs after creating PGO builds on Windows. The focus of this project is to determine what is causing these crashes or bugs and either patch/fix them or find solutions to allow for the optimizations without incurring the problems. == Project Leader(s) == [[User:cbishop2|Chris Bishop]] == Project Contributor(s) == - None so far but that will change.
