for mips/aarch64 this can be done relatively easy — for prologue like addiu sp,sp,-688 we can find DW_AT_low_pc of function and then check section .debug_frame with found pc: DW_CFA_advance_loc: 4 to 00001ce0 DW_CFA_def_cfa_offset: 688 However for x86_64 FDE for functions looks like huge list of DW_CFA_offset & DW_CFA_advance_loc and DW_CFA_def_cfa_offset is always 16. DW_AT_frame_base also always consists only from 1 byte block - DW_OP_call_frame_cfa Is it possibly to extract frame size for x86_64?
