c file

Dear,

i am compiling a simple test file (attached), generated output includes non
coldfire mcf5307/m68k opcodes.

/toolchain_path/m68k-elf-gcc -I../../../../include -I../../include -D__KERNEL__
-DCONFIG_SYS_TEXT_BASE=0xffc00000 -Wall -Wstrict-prototypes
-Wno-format-security -fno-builtin -ffreestanding -fno-stack-protector -g
-Wno-format-nonliteral -fno-toplevel-reorder -D__M68K__ -mcpu=5307 -Os
-ffunction-sections -fdata-sections -ffixed-d7 -msep-data -pipe cpu_init_t.c -c

Wrong opcode is for the c call to square_tes() jpm (see after the 3 nop,
0x4e71).

removing "-msep-data" i see correct opcode.
