Hi all,
I have a question about the generated asm code by openrisc
compiler. I have code like that there is some word definition in the
routine(shows in the following codes).
l.nop # nop delay slot
.L164:
l.jal _toupper # delay slot filled
l.lbs r3,1(r5) # extendqisi2
l.addi r11,r11,-66
l.addi r3,r0,22 # move immediate
l.sfgtu r11,r3
l.bf .L144
l.nop # nop delay slot
l.slli r3,r11,2
l.movhi r4,hi(.L145) # move immediate (high)
l.ori r4,r4,lo(.L145) # move immediate (low)
l.add r3,r3,r4
l.lwz r4,0(r3) # SI load
l.jr r4
l.nop # nop delay slot
.section .rodata
.align 4
.align 4
.L145:
.word .L108
.word .L113
.word .L144
.word .L114
.word .L119
.text
.L108:
l.addi r4,r0,1 # move immediate
l.movhi r3,hi(_Main_Bitstream_Flag) # move immediate (high)
l.ori r3,r3,lo(_Main_Bitstream_Flag) # move
immediate (low)
l.sw 0(r3),r4
l.addi r4,r0,0 # move immediate

And if I rearrange the sequency of instruction for some purposes except
the word definition(I will make sure the rearragement of instruction
donot affect the result), It will affect the output of the fuction. Or I
just put the word difinition to the end of the function(subroutine), I
would not do any rearrangement of the instruction. Dose it will afftect
the output of the function?

Thank you very much.

Regards,

Stephen
