Hi I've compiled a short program with two different gcc versions (3.2.3 and 3.4.3) but it seems that the produced assembly code isn't the same. In fact 3.4.3 produce a more important code. For example when gcc 3.2.3 produces : movl $0x405c28f6, -4(%ebp) gcc 3.4.3 may use: movl $0x405c28f6, %eax movl %eax, -4(%ebp) I wonder why it now uses %eax register ? And is there any way to prevent this, in order to have similar assembly code with both gcc versions ? Maybe some kind of option ? Thanks for your answers.
