Created attachment 49921 [details, diff]
small patch which resolves the problem (just a quick hack)

does this work properly?
there is some difference between fpu_proto.h and reg_ld_str.c:

fpu_proto.h: extern int FPU_load_int16(bx_address _s, FPU_REG *loaded_data)
BX_CPP_AttrRegparmN(2);

reg_ld_str.c: int BX_CPP_AttrRegparmN(1) FPU_load_int16(bx_address _s, FPU_REG
*loaded_data)

i have no idea why that definitions are written this way.

[Comment 2 Luca Barbato 2005-10-26 16:49:25 UTC]

I think it isn't a problem anymore with the 2.2.1, is it?
