Hi, The X64 passes the first six arguments in registers %rdi, %rsi, .... Can I use one compiler option like "-save_args" to store argments in stack like what the i386 does?

    I tried this option, but it's failed. The logs are here:

cc -O -g -save_args -m64 -c -o cpc.o cpc.c
cc: -a conflicts with -dy.
*** Error code 1
make: Fatal error: Command failed for target `cpc.o'

Thanks


Try

-Wu,-save_args
