Some analysis have been done in bug #40836 (comments 20 + 21): the WLDRW operation which would be required for this insn allows only 10 (effective 8) bit but not 12 bit for the immediate offset. E.g. the '-3888' in WLDRW wcgr0, [fp, #-3888] is not possible. -- enrico dot scholz at informatik dot tu-chemnitz dot de changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |enrico dot scholz at | |informatik dot tu-chemnitz | |dot de http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37987
