Hi
I'm just starting out with or1k assembler and I've been reading through crt0.S
in http://git.openrisc.net/cgit.cgi/stefan/orpsoc/tree/sw/drivers/or1200/crt0.S
Just one question, shouldn't 'l.addi r5, r5, 4' be placed prior to 'l.bf
1b'?
ENTRY(_start)
/* Cache initialisation */
l.jal _cache_init
l.nop
/* Clear BSS */
LOAD_SYMBOL_2_GPR(r5, _bss_start)
LOAD_SYMBOL_2_GPR(r6, _bss_end)
1:
l.sw (0)(r5), r0
l.sfltu r5, r6
l.bf 1b
l.addi r5, r5, 4
/* Jump to main program entry point (argc = argv = 0) */
CLEAR_GPR(r3)
CLEAR_GPR(r4)
l.jal main
l.nop
/* If program exits, call exit routine */
l.addi r3, r11, 0
l.jal exit
l.nop
