Package: sprng
Version: 2.0a-6
Severity: serious
Tags: patch
Since GCC 4.4 it's not possible anymore to use the 'h' constraints for
MIPS inline assembly code when doing a multiplication. That's why sprng
fails to build from source on mips and mipsel.
That said GCC supports 32x32 => 64 multiplication on 32-bit architecture
for a lot of time, so there is no need to use assembly code for that.
The patch below fixes the problem by using standard multiplication
instead of assembly code.
