(Get the code!)
The -mtune=cortex-a8 will optimise the generated code for the Cortex-A8 (ARMv7 processor) pipeline but not affecting the instruction set used (which is still ARMv5T). The resulting code will be optimal on ARMv7 but there may be a slight drop (if any) on other architecture versions.
Without the Debian gcc patches for forcing ARMv4T, the default in gcc I think is ARMv5T anyway.
AFAIK, the Xscale platform is ARMv5T but without the VFP coprocessor (affected by the -mfpu=vfp option). Is Thecus planned to be a supported platform by the upcoming ARM Ubuntu port?
