I have the same problem on armeb-softfloat-linux-uclibc. I also have |
| 14 |
apps that fail with __fixdfsi. Many of the busybox applets fail with |
| 15 |
__udivsi3 (e.g. awk, ping, top, df, netstat, fdisk) - basically |
| 16 |
anything that does a certain kind of floating point divide. They only |
| 17 |
fail when that specific instruction is reached, so for example ash |
| 18 |
would only fail if mod or div is used e.g. "echo $((5 % 2))" or "echo |
| 19 |
$((16 / 4))". |

So far I have been unable to construct a test case - my own test app |
| 22 |
that does floating point div also works. |

I suspect that it is a bug in gcc and the way it generates code on ARM |
| 25 |
softfloat targets, but I have no idea how to find out. |
