On x86_64-linux I get 0000000000000040 <md5_read_ctx>: 40: f3 0f 6f 07 movdqu (%rdi),%xmm0 44: 48 89 f0 mov %rsi,%rax 47: 0f 11 06 movups %xmm0,(%rsi) 4a: c3 retq 4b: 0f 1f 44 00 00 nopl 0x0(%rax,%rax,1) for it (with -O3, that is). Can you please tell me how to configure a cross (from x86_64-linux) and attach preprocessed source of md5.c?
