The problem is, that when "rewritten" gets inlined (in -O2+ case), you can't
expect argument to be passed into the inlined section of the function via
locations, specifed by ABI. So, you have:
$main..ng:
lda $30,-48($30) #,,
stq $26,16($30) #,
stq $9,24($30) #,
.prologue 1
stq $31,32($30) # array,
stq $31,40($30) # array,
.set macro
# 35 "test.c" 1
ldq $1,0($16) # b0 # b0
clr $3 # ofs # ofs
ldq $2,8($16) # b1 # b1
cmoveq $1,64,$3 # ofs = (b0 ? ofs : 64); # b0, ofs
cmoveq $1,$2,$1 # output = (b0 ? b0 : b1); # b0, b1
cttz $1,$4 # temp = cttz(temp); # b0, temp
addq $4,$3,$9 # ret = temp + ofs # temp, ofs, result_1
which is clearly wrong, due to wrong ASM.
So, invalid.
