ARM assembly: bad instruction 'ldrbcc' -


i writing arm assembly code. in there snippet:

cmp r3, r2 ldrbcc r6, [r3], #1

i want express if r3 less r2, load [r3] register r6. when compile linaro toolchain(version 13.04):

arm-linux-gnueabihf-as -march=armv7-a -mcpu=cortex-a9 test.s -o test

the compiler outputs:

error: bad instruction `ldrbcc r6,[r3],#1'

i can't figure out. can me? thanks.

ldrbcc modern "unified assembly language"; assembler defaulting older pre-ual syntax , expects ldrccb. could change code use pre-ual syntax, better solution tell assembler using ual style adding ".syntax unified" directive before code.
