The linking order of object files affects the actual code placement, which in turn affects the size of fill section due to the number of zeros required to maintain appropriate data/code alignment may change. This is observed when building on Mac and Linux host. example: mbed compile -m K64F -t GCC_ARM (build 1) +---------------------+-------+-------+-------+ | Module | .text | .data | .bss | +---------------------+-------+-------+-------+ | Fill | 120 | 4 | 2381 | | Misc | 28755 | 2216 | 84 | | features/frameworks | 4236 | 52 | 744 | | hal/common | 2745 | 4 | 325 | | hal/targets | 12116 | 12 | 200 | | rtos/rtos | 119 | 4 | 0 | | rtos/rtx | 5721 | 20 | 6786 | | Subtotals | 53812 | 2312 | 10520 | +---------------------+-------+-------+-------+ example: mbed compile -m K64F -t GCC_ARM (build 2) +---------------------+-------+-------+-------+ | Module | .text | .data | .bss | +---------------------+-------+-------+-------+ | Fill | 128 | 4 | 2381 | | Misc | 28755 | 2216 | 84 | | features/frameworks | 4236 | 52 | 744 | | hal/common | 2745 | 4 | 325 | | hal/targets | 12116 | 12 | 200 | | rtos/rtos | 119 | 4 | 0 | | rtos/rtx | 5721 | 20 | 6786 | | Subtotals | 53820 | 2312 | 10520 | +---------------------+-------+-------+-------+ This patch fixes fill section size variation by sorting object files before passing to linker.
