void cond(long a, long *p) { if (p&&a>*p) *P=a; }GCC会产生下面的汇编代码: void cond(long a, long *p) a in %rdi,p in %rsi cond: testq %rsi,%rsi je .L1 cmpq %rdi,(%rsi) jge .L1 movq %rdi,(%rsi) .L1: rep; retA.按照图3-16 b中所示的风格,用C语言写一个goto版本,...
使用如下命令进行编译和反编译: $ gcc -Og -fno-stack-protector -c call_proc.c $ objdump -d call_proc.o 其中-fno-stack-protector参数指示编译器不添加栈保护机制 生成的汇编代码如下,这里我们仅看call_proc()中的栈空间分配 0000000000000015<call_proc>: 15:4883ec10sub$0x10,%rsp 19:48c74424080100mo...

This port requires as least binutils 2.35, GCC 11, and Linux 5.4. Currently only soft-float ABI is supported: - or1k-linux-gnu The OpenRISC ABI is 32-bit big-endian and uses 64-bit time (y2038 safe) and 64-bit file offsets (LFS default). * A new configure option, --with-rtld...
