From 962937b15dd570e44109f3c8196a392b788837ba Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Thu, 31 Mar 2022 13:32:20 -0400 Subject: [PATCH] gdb: make timestamped_file implement can_emit_style_escape In our AMDGPU downstream port, we use styling in some logging output. We noticed it stopped working after the gdb_printf changes. Making timestamped_file implement can_emit_style_escape (returning the value of the stream it wraps) fixes it. To show that it works, modify some logging statements in auto-load.c to output style filenames. You can see it in action by setting "set debug auto-load 1" and running a program. We can incrementally add styling to other debug statements throughout GDB, as needed.
