gputils (rev.610) supports now 12f1822, is it possible that next sdcc revision also supports this chip ?
SDCC supports the 12f1822 since rev. 6896. Until the next gputils release and further notice, you need to specify
configure --enable-new-pics [more options]
to create the relevant device library files.
Due to the architectural differences of the 12f1822 esp. with respect to data banking/indirect memory access, support for the device must be considered incomplete (at best) or even completely broken.
