Hi,
I've checked the i386.c file.
But I am curious about something as follows.
1. "large" insn
2. MOVE_RATIO
3. cost for loading QImode using movzbl
Does anybody know what those mean?
Any help is appreciateed.
Best Regards,
Joseph
A part in the i386.c file
struct processor_costs pentiumpro_cost = {
1, /* cost of an add instruction */
........
8, /* "large" insn */
6, /* MOVE_RATIO */
2, /* cost for loading QImode using movzbl */
.......
32, /* size of prefetch block */
6, /* number of parallel prefetches */
};

Hi,
I want to add an GCC parameter for my own test.
But I have no idea what file I should modify.
Could anybody tell me how to do this?
Any help is appreciated.
BR,
Joseph
