Francis Visoiu Mistrih 648e1e248b [AArch64] Emit CSR loads in the same order as stores ... Optionally allow the order of restoring the callee-saved registers in the epilogue to be reversed. The flag -reverse-csr-restore-seq generates the following code: ``` stp x26, x25, [sp, #-64]! stp x24, x23, [sp, #16] stp x22, x21, [sp, #32] stp x20, x19, [sp, #48] ; [..] ldp x24, x23, [sp, #16] ldp x22, x21, [sp, #32] ldp x20, x19, [sp, #48] ldp x26, x25, [sp], #64 ret ``` Note how the CSRs are restored in the same order as they are saved. One exception to this rule is the last `ldp`, which allows us to merge the stack adjustment and the ldp into a post-index ldp. This is done by first generating: ldp x26, x27, [sp] add sp, sp, #64 which gets merged by the arm64 load store optimizer into ldp x26, x25, [sp], #64 The flag is disabled by default. llvm-svn: 327569		2018-03-14 20:34:03 +00:00
