我在 Cygwin(Windows7-64 位)中使用 gcc 来运行这个例子 http://asm.sourceforge.net/howto/build.html
.data # section declaration
msg:
.ascii "Hello, world!\n" # our dear string
len = .-msg # length of our dear string
.text # section declaration
# we must export the entry point to the ELF linker or
.global _start # loader. They conventionally recognize _start as their
# entry point. Use ld -e foo to override the default.
_start:
# write our string to stdout
movl $len,%edx # third argument: message length
movl $msg,%ecx # second argument: pointer to message to write
movl $1,%ebx # first argument: file handle (stdout)
movl $4,%eax # system call number (sys_write)
int $0x80 # call kernel
# and exit
movl $0,%ebx # first argument: exit code
movl $1,%eax # system call number (sys_exit)
int $0x80 # call kernel
通过 Cygwin 中的命令行 $as -o hello.o hello.s && ld -s -o hello hello.o && ./hello 结果是 分段错误
你能帮助我吗?
