| 9 | Reading the webpage linked it seems like that thing has a hardware FPU, |
| 10 | so you can use your suggestion. However, arm-unknown-linux-gnu will |
| 11 | procude ARM OABI code. You might also want to try |
| 12 | |
| 13 | arm-unknown-linux-gnueabi |
| 14 | |
| 15 | to use ARM EABI instead. See |
| 16 | |
| 17 | http://www.gentoo.org/proj/en/base/embedded/handbook/index.xml?part=1&chap=3 |
| 18 | |
| 19 | Furthermore according to |
| 20 | http://www.arm.com/products/CPUs/ARM1136JF-S.html |
| 21 | http://gcc.gnu.org/onlinedocs/gcc-4.3.3/gcc/ARM-Options.html#ARM-Options |
| 22 | |
| 23 | I would use |
| 24 | |
| 25 | -march=armv6j -mtune=arm1136jf-s |
| 26 | |
| 27 | in the CFLAGS. |
