[ARM] 4264/1: ldrex/strex syntax errors with recent compilers
Trying to build some code using atomic_clear_mask() on a ARM v6
processor with a recent compiler (tried with gcc version 4.1.1
(CodeSourcery ARM Sourcery G++ 2006q3-26), but
all gcc > 4.1 might be affected) results in the following:
/tmp/ccWKLJV8.s: Assembler messages:
/tmp/ccWKLJV8.s:581: Error: instruction does not accept this addressing
mode -- `ldrex r0,r3'
/tmp/ccWKLJV8.s:583: Error: instruction does not accept this addressing
mode -- `strex r1,r0,r3'
Older gcc (like gcc version 4.0.0 (DENX ELDK 4.1 4.0.0)) have no problem
with this.
The patch below fixes the compile error. I also verified that gcc-4.0.0 generates identical code using both forms.
