Re: memcpy on 68000

[Matthias Reis <matthias.reis@physik.tu-berlin.de>]

I'm using gcc 4.2.4

$ /usr/local/m68k-uclinux/bin/gcc --version
gcc (GCC) 4.2.4

downloaded from http://www.uclinux.org/pub/uClinux/m68k-elf-tools/tools-20080626/m68k-uclinux-tools-20080626.sh .

This is the gcc command line for memcpy:

  /usr/local/m68k-uclinux/bin/gcc -Wp,-MD,arch/m68k/lib/.memcpy.o.d  -nostdinc -isystem /usr/local/lib/gcc/m68k-uclinux/4.2.4/include -I/home/unsortiert/linux-m68k/arch/m68k/include -Iarch/m68k/include/generated -Iinclude  -include include/generated/autoconf.h -D__KERNEL__ -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -Werror-implicit-function-declaration -Wno-format-security -fno-delete-null-pointer-checks -O2 -m68000 -mstrict-align -pipe -DUTS_SYSNAME=\"uClinux\" -D__uClinux__ -fno-stack-protector -fno-omit-frame-pointer -fno-optimize-sibling-calls -g -Wdeclaration-after-statement -Wno-pointer-sign -fno-strict-overflow    -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(memcpy)"  -D"KBUILD_MODNAME=KBUILD_STR(memcpy)" -c -o arch/m68k/lib/memcpy.o arch
 /m68k/lib/memcpy.c

As you can see, I tried  -mstrict-align, but I got the same error as previously.
