Hi, I am building colilo for a coldfire (v4e) target. I am facing a strange problem. If i build colilo with -O0 option and convert the ELF binary to bnary, srec format following are the resulting file sizes -rwxr-xr-x 1 cjaiprakash coldfire 93K Nov 25 18:58 colilo.bin -rwxr-xr-x 1 cjaiprakash coldfire 123K Nov 25 18:58 colilo.elf -rw-r--r-- 1 cjaiprakash coldfire 279K Nov 25 18:58 colilo.s19 -rw-r--r-- 1 cjaiprakash coldfire 279K Nov 25 18:58 colilo.srec But when i build the colilo with -O2 option file size increase significantly, following are the sizes -rwxr-xr-x 1 cjaiprakash coldfire 17M Nov 25 19:01 colilo.bin -rwxr-xr-x 1 cjaiprakash coldfire 107K Nov 25 19:01 colilo.elf -rw-r--r-- 1 cjaiprakash coldfire 49M Nov 25 19:01 colilo.s19 -rw-r--r-- 1 cjaiprakash coldfire 49M Nov 25 19:01 colilo.srec ELF binary size is ok but why the file sizes for bin, srec are so huge?
