Code Generation
A starter program codgen.c is furnished. A very simple program, triv.pas, can be compiled by codgen.c:
program graph1(output); var i:integer; begin i := 3 end.
The result is triv.s:
.globl graph1 .type graph1, @function graph1: ... subq 32,ドル %rsp # space for stack frame # --------- begin Your code ------- movl 3,ドル%eax # 3 -> %eax movl %eax,-32(%rbp) # i := %eax # --------- begin Epilogue code --- leave ret
