SBR600: To Thumb? or Not to Thumb? (v0.1) continued.. 4

I have to apologize that, my previous blog entry was incorrect.

I compiled, benchmarked and posted my result without understanding rpmbuild fully.

For those who are unsure about directories rpmbuild uses, here's little description for you that I grabbed from the Internet.

rpmbuild/SOURCES — Contains the original sources, patches, and icon files.

rpmbuild/SPECS — Contains the spec files used to control the build process.

rpmbuild/BUILD — The directory in which the sources are unpacked, and the software is built.

rpmbuild/RPMS — Contains the binary package files created by the build process.

rpmbuild/SRPMS — Contains the source package files created by the build process.

Today, I will post some of my recent benchmark results. In addition to Non-THUMB vs. THUMB, I've compiled with an armv7 chip using THUMB2 mode as well.

All of the compiling was done by rpmbuild, all the rpm macro settings were identical except -march=armv5tel, -march=armv5tel -mthumb -mthumb-interwork and -march=armv7 -mthumb.

The numbers inside the table represent file/directory sizes in bytes. File sizes are checked with ll and directory sizes are checked with du --bytes.
