From 970c6b7e156107e961dd7b3ac0ad33d9fccb6bff Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Fri, 28 Apr 2023 14:27:13 -0400 Subject: [PATCH] gdb: remove ui_interp_info I don't think that having struct ui_interp_info separated from struct ui is very useful. As of today, it looks like an unnecessary indirection layer. Move the contents of ui_interp_info directly into struct ui, and update all users.
