Hey guys, I have the newest dev environment set up on linux, and this isn't about HelloWorld. I've searched the forum and couldn't find a post about other operands... this is happening when compiling the source released for Snake:

ra = 31
s0 = 16
s1 = 17

a0 = 4
a1 = 5
a2 = 6
a3 = 7
t0 = 8
t1 = 9

v0 = 2

ie: sw $s0,4($sp) would be sw $16, 4($sp)
hope that helps..

thank you very much, squiggle, that fixed all the operand issues.

all that's left is an error on line 104:
Quote:

startup.S:104: Warning: setting incorrect section attributes for .rodata.entrytable
>>> .section .rodata.entrytable,"wa",@progbits
__entrytable:
.word 0xD632ACDB
.word 0xF01D73A7
.word _start
.word __moduleinfo
.word 0


which is identical to the .section line from helloworld, but for snake it's not working. any idea?
