Hi Guys,
I'm currently trying to build uClibc-0.9.30-rc1 for SH2aeb and found an
issue when building which I fixed with the attached patches.
make[2]: Entering directory `/opt/sh/2a/build/src/test-apps-0.1'
sh2aeb-linux-uclibc-gcc -Wl,-EB test.c -o test
test.c: In function 'main':
test.c:5: warning: return type of 'main' is not 'int'
/opt/sh/2a/toolchain/usr/lib/libc.a(memcpy.o): In function `memcpy':
memcpy.c:(.text+0x60): undefined reference to `WORD_COPY_FWD'
collect2: ld returned 1 exit status
make[2]: *** [test] Error 1
I think its the right thing to do - i.e. follow the SH4, and define
ARCH_HAS_BWD, but then I had to copy the include from memmove to memcpy
which I don't think is a particularly nice way to do this. Why is it
currently including a .c file in this way?
