I am using GCC to compile code for an arm-elf target, and have recently changed from GCC 3.2.1 to GCC 3.4.3. GCC is now generating a stack frame that is about 14KB larger in one of my functions. I have examined the code carefully, and cannot see why this is so. With GCC 3.2.1, the stack frame was about 1800 bytes. With GCC 3.4.3, the stack frame is now > 16KB. Same source code. Has anyone seen this kind of behavior? I compiled the code with the '-v -save-temps' option and examined the assembly code. I cannot see where the code even accesses any of the extra stack frame area. Is there a compiler option to generate a function stack map? Thanks. Jay
