Is mrs for float special register not valid on cortex-a9 ?
Thank you
~Umesh
that's because the instruction you want is
vmrs r4, fpscr
R.
Also note that the fmrrs mnemonic is not part of the UAL (unified
assembly language) specification - it was deprecated a long time ago.
The correct names these days all start with a V - the disassembler
output shows the modern form.
The legacy name for vmrs was fmrx.
R.
