Hi,
I built Diolan USB HID bootloader with mpasm.
The bootloader uses the PIC16 extended instruction set / literal offset addressing mode (Config. bit CONFIG4L XINST = ON).
In order to make my sdcc programs working with this bootloader, I also need to use this mode.
I tried to compile/link with the -extended option (last svn revision from gputils/sdcc) without success.
I saw what documentation says about this extended mode support :

Known Bugs : The PIC16 port emits code which is incompatible with the extended instruction set available with many newer devices. Make sure to always explicitly disable it …

Is there any chance to get this mode working in a near future ?
Thank you.
