The output binary files are different built by arm-gcc 5.3 linux and win32.

We used the arm-gcc-4.8 (Linux/win32) to build our codebases in Linux OS and Windows MinGW.
The MinGW output binary file is same as Linux binary file.

But the two binary files are different after we used arm-gcc-5.3 (Linux/win32). (same codebase, same compiler option)

such as

The elf.s disassembly code built by arm-gcc-5.3-linux is described as bleow.

100871ac: 9f08 ldr r7, [sp, #32]
100871ae: 9b09 ldr r3, [sp, #36] ; 0x24

The result by arm-gcc-5.3-win32is:
