Now that copies and constants are tracked separately, we can allow constant to have copies, deferring the choice to use a register or a constant to the register allocation pass. This prevent this kind of regular constant reloading: -OUT: [size=338] +OUT: [size=298] mov -0x4(%r14),%ebp test %ebp,%ebp jne 0x7ffbe9cb0ed6 mov $0x40002219f8,%rbp mov %rbp,(%r14) - mov $0x40002219f8,%rbp mov $0x4000221a20,%rbx mov %rbp,(%rbx) mov $0x4000000000,%rbp mov %rbp,(%r14) - mov $0x4000000000,%rbp mov $0x4000221d38,%rbx mov %rbp,(%rbx) mov $0x40002221a8,%rbp mov %rbp,(%r14) - mov $0x40002221a8,%rbp mov $0x4000221d40,%rbx mov %rbp,(%rbx) mov $0x4000019170,%rbp mov %rbp,(%r14) - mov $0x4000019170,%rbp mov $0x4000221d48,%rbx mov %rbp,(%rbx) mov $0x40000049ee,%rbp mov %rbp,0x80(%r14) mov %r14,%rdi callq 0x7ffbe99924d0 mov $0x4000001680,%rbp mov %rbp,0x30(%r14) mov 0x10(%r14),%rbp mov $0x4000001680,%rbp mov %rbp,0x30(%r14) mov 0x10(%r14),%rbp shl $0x20,%rbp mov (%r14),%rbx mov %ebx,%ebx mov %rbx,(%r14) or %rbx,%rbp mov %rbp,0x10(%r14) mov %rbp,0x90(%r14) mov 0x60(%r14),%rbx mov %rbx,0x38(%r14) mov 0x28(%r14),%rbx mov $0x4000220e60,%r12 mov %rbx,(%r12) mov $0x40002219c8,%rbx mov %rbp,(%rbx) mov 0x20(%r14),%rbp sub $0x8,%rbp mov $0x4000004a16,%rbx mov %rbx,0x0(%rbp) mov %rbp,0x20(%r14) mov $0x19,%ebp mov %ebp,0xa8(%r14) mov $0x4000015110,%rbp mov %rbp,0x80(%r14) xor %eax,%eax jmpq 0x7ffbebcae426 lea -0x5f6d72a(%rip),%rax # 0x7ffbe3d437b3 jmpq 0x7ffbebcae426 Backports commit 299f80130401153af1a6ddb3cc011781bcd47600 from qemu |
