From 93e39555dd0fcd222ce68fc7162f511056361bc7 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 13 Dec 2022 22:34:40 -0500 Subject: [PATCH] gdb: make frame_info_ptr grab frame level and id on construction This is the first step of making frame_info_ptr automatic. Remove the frame_info_ptr::prepare_reinflate method, move that code to the constructor.
