anal_mips.c:mips_op() <-- op.c:r_anal_op() <-- anal.c:r_core_anal_search()

anal.c:r_core_anal_search() --> if ( R_ANAL_OP_TYPE_CALL) r_core_anal_followptr(,at+i,ptr=op.jump,ref,TRUE,depth==0 (why?))
  --> r_core_anal_followptr(): if (ptr==ref && code==TRUE) "ar ref at" else ard ref at (data)
           if ptr != ref depends on depth; then an endian calculation(!)used in r_io_read_i then self recurse

But:  ar reports  xref.code.call.0x0060nnnn - so again seems to be up to mips_op() or maybe r_anal_op chain to add base address?

also report xref.code.call.0x0060nnnn=0 i,e, at is 0 (?) didnt find the dest?

# Assumes strings are referenced downwards from the top of a segment

f string_end @ 0x80620000

# then addui a0,a0,-12288    <-- string is at 0x8061d000

# This used to add a comment with the text but that broke recently
# So now it adds a comment String_addressofstring
# It adds a xref mut I am still perfecting that

What is the purpose of the configure script - is it specific to ccan or is it intended to be more like a typical ./configure script?

e.g. when run on a fresh VM it doesn't detect when you have not yet installed the SSL development package, so the first time you realise that SSL is missing is when make fails. Also it doesnt warn you have not yet installed valgrind then make fails not finding valgrind

Perhaps I am spoiled from working with larger projects long established with autoconf :-)
