Re: FPC does SIGILL in armv4t
strd/ldrd were first introduced in armv5t
"Architecture v5TE and later processors provide LDRD and STRD
instructions to load/store 64-bit data, e.g. to access 64-bit
peripherals. These behave similarly to LDM/STM of two registers."
ldrd just loads 64-bit data (ok, atomically) into two registers.
LDRD r0,[r6]
seems to be equivalent to
LDM r6, {r0,r1}
Best ref I could find were
LDRD: http://www.rz.uni-karlsruhe.de/rz/docs/VTune/reference/INST_LDRD.htm
Correct me if I'm wrong.
