I used stock gcc 4.1.1 to get the result: mips-linux-gcc -O2 -S foo.c
If I used -O instead of -O2, I got similer (but not same) result:
foo:
.frame $sp,0,$31 # vars= 0, regs= 0/0, args= 0, gp= 0
.mask 0x00000000,0
.fmask 0x00000000,0
.set noreorder
.cpload $25
.set nomacro
bne $4,$0,$L2
.set push
.set mips32r2
rdhwr $3,$29
.set pop
j $31
move $2,$0
$L2:
lw $2,%gottprel(x)($28)
nop
addu $2,$2,$3
lw $2,0($2)
j $31
nop
JFYI.
Should I file a bug report?
