Project Details

Find a set of compiler flags that creates smaller and more efficient binaries for Pidora, compared to the current compiler flags.

A set of packages will be selected for testing, to cover a range of dependencies and use cases, such as common utilities, libraries, and GUI tools.

The packages will be built in a Mock environment on an ARMv6 machine.

Goals by Release

Goals for each release and plans for reaching those goals:

0.1

• Create a script that compiles a list of packages from source, using different combinations of compiler flags, and outputs the sizes of the compiled binaries
• Find multiple combinations of compiler flags that create smaller binaries

0.2

• Test the combinations found in 0.1 against a larger set of packages to ensure there is a consistent reduction in binary size
• Test the performance of the smaller binaries and determine which set of compiler flags yields the best performace

0.3

• Submit a patch to the rpm package recommending the new compiler flags
