PGO Related Bugs

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.

Performance

PGO Build Results ( Sept 20th, 2008 )

The program loads 15,000 random records from a text file into 4 tables each using a different method for storage and searching.

Simple Table: Uses an array and a linear search.
Chain Table: Uses an array of link lists. Search is done with a Hash Key.
Hash Table: Uses an array and searches with linear probing. Also uses a Hash Key.
Tree Table: Uses a binary search tree.

After the data is loaded into a table, 30 different tests are run against it. The same 30 tests for each table. Here are the Results.

	Non-PGO	PGO	Improved By
Simple Table:	28 Secs	4 Secs	7x
Chain Table:	0.109 Secs	0.047 Secs	2.3x
Hash Table:	0.141 Secs	0.047 Secs	2.3x
Tree Table:	0.287 Secs	0.078 Secs	3.6x

-|I built Firefox with the command <code>make -f client.mk profiledbuild</code>.  This first compiles Firefox with extra code that watches the activity in Firefox and creates profile data to optimize Firefox.  After Firefox is compiled it runs a script that loads the browser.  While the browser it is outputting profile data about the activity. After the browser is closed it compiles again but this time using the profile data to optimize Firefox to run faster on Windows.<br /> <br />
-During the compiling of Firefox I received a lot of warnings.  Then Minefield loaded and after typing in an URL an Assertion happened.  Firefox closed and continue to compile using the profile data but it failed with errors.  I tried again this time just closing the browser after it started but again it failed to compile with the profile data.<br /><br />
-I'll post the output and error logs online.
-Here are some of the errors.
-Here is link to build [http://zenit.senecac.on.ca/wiki/imgs/Sept22build-.zip output].

-|My previous attempts at compiling the old assignment failed because I was including object files that were compiled with a different compiler. Oops.  I was successful at creating a PGO build with an old assignment.  The results are under Project Details<br />

-I think I will look at the optimization data to figure out how it optimized my application.  I also need to build an optimized version of Firefox and run it.  I know it has bugs or crashes, that is the point of this project so I also need to figure out how to compile and debug Firefox in Visual Studio.   <br /><br />
