Radare2 macro (work in progress) for string scanning a stripped / embedded MIPS binary for strings

gistfile1.txt

# Assumes strings are referenced downwards from the top of a segment
# e.g - set

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
