--- Comment #2 from LYZ <lingyouz...@arimacomm-hz.cn> 2011-08-15 08:01:26 UTC --- I am a new here, I try 4.4.1 still same issue. My compile is arm-none-eabi-gcc-4.4.1.exe. Yes Thumb-1 code, but I not sure whether same as PR38644. (In reply to comment #1) > Is this Thumb-1 code? If so then I suspect this is a duplicate of PR38644.
