Hi all,
Can gatekeeper help review this fix?
For more detailed info please refer to
https://bugs.open64.net/show_bug.cgi?id=782
In general, when run following command,
opencc -m elf_i386 -O0 -m32 a.c b.c -c
opencc -o a.so -m elf_i386 a.o b.o -shared -nostdlib -show
It will generate 64bit a.so but not 32bit.
The root reason is when open64 pass "-m" "elf_i386" and "-m"
"elf_x86_64" to linker, it
treat them as group "-m elf_i386", and "-m elf_x86_64", which confused the gcc
driver.
The fix is:
