strexd r0, r1,r2,[r4]
produces
arm.asm:275: Error: even register required -- `strexd r0,r1,r2,[r4]'
failed, quitting
cmd was
$arm-linux-elf-as -mcpu=arm1176jzf-s -mfpu=vfpv2 -o $1.o $1.asm
I can find nothing in
ARM Architecture
Reference Manual
ARM v7-A and ARM v7-R edition
Errata markup
which indicates that any of the registers must be evenly numbered?
1. Which reg is wrong (unclear error message?)
2. Is it an error at all?
regards
