   Hi alanyih,

   I'm glad to see you here again!
   I know that you difficult to talk in English. But, what you mean by that?
   I see only that

   • you have installed gcc-4.5.2 (used in SliTaz 4.0 Stable) on your system, and
   • you have installed gcc-4.6.3 (used in SliTaz Cooking) on your chroot

   And yes, you can continue your experiments with ARM. (But, unfortunately, I do not have any ARM.)

   ArmHardFloatPort

   This page gathers thoughts and ideas around a new hard-float ABI ARM port for Debian, hopefully to be released for the the first time with Wheezy (7.0).

   Raspbian Benchmarking – armel vs armhf
   http://www.memetic.org/raspbian-benchmarking-armel-vs-armhf

   Softfp and Hardfp

   For ARM there are two different ABIs (Application Binary Interfaces), soft/softfp and hard. ‘soft’ doesn’t use the FPU at all and uses gcc maths replacement functions to emulate floating point arithmetic. ‘softfp’ uses the FPU but arguments to functions are passed through the integer registers and then passed to the floating point unit. ‘hard’ is using the FPU directly with data passed directly to the floating point unit registers. While soft/softfp are forwards compatible, ie. a ‘soft’ app can run on a softfp system, but not vice-versa, a ‘hardfloat’ application can run on neither of those systems. This means that in order to use hardfloat the system has to be completely recompiled for the hardfloat ABI, down to the last library and program.

   Benchmark

   Given the preponderance of hardfp performance over its register ignorant peers, this will be useful in eking every last drop of performance out of the hardware.

   Raspbian Benchmarking – armel vs armhf
   http://www.memetic.org/raspbian-benchmarking-armel-vs-armhf/

   Keep in mind the golden rule of benchmarking: All benchmarks are flawed benchmarks.
   
   Performance comparison between Debian armel and Raspbian armhf

   The chart above shows the performance difference in various applications between Debian armel and Raspbian armhf. Performance improvement varied from 4% to 40% depending upon the application.

   [..]

   Conclusion

   I believe the QtonPi wiki best sums up my experiences:

   Given the preponderance of hardfp performance over its register ignorant peers, this will be useful in eking every last drop of performance out of the hardware.

    SliTaz armhf: 46MB Linux Distribution for Raspberry Pi

    http://www.cnx-software.com/2012/12/15/slitaz-armhf-46mb-linux-distribution-for-raspberry-pi

    SliTaz armhf is a minimal Linux distribution based on SliTaz Linux, that uses the hard-float ABI for the Raspberry Pi. The compressed SD card image is 46M, the rootfs 18.6 MB, and Slitaz uses just about 7 MB RAM after boot.
