[ECOS] compiled result not align to 4 bytes

["Frank Lin" <franklin373 at gmail dot com>]

I developed an application, but has problem, I use arm-elf-object -D ??? to got latter result, I find these code compiled from assembly file context.s not aligh to 4 bytes. 

My global compiler flags is:  
mcpu=arm7tdmi -mno-short-load-words -Wall -Wpointer-arith -Wstrict-prototypes -Winline -Wundef -Woverloaded-virtual -gdwarf-2 -g3 -O0 -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions -fvtable-gc -finit-priority

My global linker flags is:
-mcpu=arm7tdmi -mno-short-load-words -Wl,--gc-sections -Wl,-static -gdwarf-2 -g3 -nostdlib

Whether it is caused by gcc bug? To solve this problem, whether I should place .align 4 to every assembly file, or any simple way exists?

Latter disassembly code's right part is my comments.

Thanks.
