I just got a new laptop with an Intel Core2 Duo and tried building
gnubg there (gentoo Linux as FreeBSD can't currently support the
Radeon graphics chip nor the Intel sound chip :-(( )
I have a fix for the sse tests in neuralnet.c, which otherwise don't
compile (pushfl is not valid on this architecture, pushf pushes a 64
bit value, so the pop's must become popq's to 64 bit
registers). What's the best way of setting a #define so that
neuralnet.c can choose which assembler code to generate for 32 bit and
64 bit machines? #define ATHLON perhaps?
As a side note, when it wouldn't compile and before I found the AMD
instruction set documents, I tried building it with the -march=sse2
and -DUSE_SSE_VECTORIZE flags omitted (on a fresh fetch from cvs), yet
conf.h still had #define USE_SSE_VECTORISE 1, so the compile still
failed. What's the correct way of suppressing the sse code?
