Hi, https://news.ycombinator.com/item?id=10773849 According to the above discussion, I use the following command to get the unoptimized assembly code. But it still has things like .file, .text, .globl, .type., .size, .ident, .section. If I delete them, the resulted assembly code still can be compiled. So they are nonessential. How to make gcc only generate the essential part of the assembly code? $ gcc -O0 -fno-asynchronous-unwind-tables -S -x c -o - - <<< 'int f(int x1, int x2, int x3, int x4, int x5, int x6) { return 0; }' .file "" .text .globl f .type f, @function f: pushq %rbp movq %rsp, %rbp movl %edi, -4(%rbp) movl %esi, -8(%rbp) movl %edx, -12(%rbp) movl %ecx, -16(%rbp) movl %r8d, -20(%rbp) movl %r9d, -24(%rbp) movl $0, %eax popq %rbp ret .size f, .-f .ident "GCC: (Debian 10.2.1-6) 10.2.1 20210110" .section .note.GNU-stack,"",@progbits -- Regards, Peng
