As noted by Felix Radensky back on 16 Mar:
I've tried several times to compile uClibc with soft-float (both gcc-3.2.2 toolchain and wrapper), but applications compiled with uClibc always failed with "Invalid instruction". So I ended up disabling floating point at all and this works well. I also has no problem with glibc from Monta Vista, which is compiled with soft-float. My processor is PowerPC 405GP. Maybe the problem is in FP() macro definition in libc/sysdeps/linux/powerpc/setjmp.S and libc/sysdeps/linux/powerpc/__longjmp.S #ifdef __UCLIBC_HAS_FLOATS__ #define FP(x...) x #else #define FP(x...) #endif which should be defined as if defined __UCLIBC_HAS_FLOATS__ && ! defined __UCLIBC_HAS_SOFT_FLOAT__ #define FP(x...) x #else #define FP(x...) #endif
