It is intended to fix PR11468. Old prologue and epilogue looked like this: push %rbp mov %rsp, %rbp and $alignment, %rsp push %r14 push %r15 ... pop %r15 pop %r14 mov %rbp, %rsp pop %rbp The problem was to reference the locations of callee-saved registers in exception handling: locations of callee-saved had to be re-calculated regarding the stack alignment operation. It would take some effort to implement this in LLVM, as currently MachineLocation can only have the form "Register + Offset". Funciton prologue and epilogue are now changed to: push %rbp mov %rsp, %rbp push %14 push %15 and $alignment, %rsp ... lea -$size_of_saved_registers(%rbp), %rsp pop %r15 pop %r14 pop %rbp Reviewed by Chad Rosier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@160248 91177308-0d34-0410-b5e6-96231b3b80d8 |
