prologue like this: __Z3fooi: Leh_func_begin1: LBB1_0: ## entry pushl %ebp Llabel1: movl %esp, %ebp Llabel2: pushl %esi Llabel3: subl $20, %esp call "L1$pb" "L1$pb": popl %esi The "pushl %ebp" needs a table entry specifying the offset. The "movl %esp, %ebp" makes %ebp the new stack frame register, so that needs to be specified in DWARF. And "pushl %esi" saves the callee-saved %esi register, which also needs to be specified in DWARF. Before, all of this logic was in one method. This didn't work too well, because as you can see there are multiple FDE line entries that need to be created. This fix creates the "MachineMove" objects directly when they're needed; instead of waiting until the end, and losing information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74952 91177308-0d34-0410-b5e6-96231b3b80d8 |
