Subject: compiler: print runtime.hex in hex
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=29ca15bb297d2a4c98224f8518206547432c2b69;p=gcc.git

compiler: print runtime.hex in hex

    The gc compiler recognizes the type runtime.hex and prints values
    in this type as hex. Do the same here. This makes debugging
    runtime crashes slightly better.
