From 0b360f1926cb15edc39c661dac2f1a433fb288c0 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Sun, 19 Nov 2017 22:23:20 -0500 Subject: [PATCH] Remove usage of find_inferior in win32-i386-low.c Straightforward replacement of find_inferior with the overload of for_each_thread that filters on pid. I am able to build-test this patch, but not run it. gdb/gdbserver/ChangeLog: * win32-i386-low.c (update_debug_registers_callback): Rename to ... (update_debug_registers): ... this, return void, remove pid_p arg.
