From d3abe1c8ef1ec9a90932b801138a144dcae95100 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Tue, 11 Jul 2017 06:44:36 -0600 Subject: [PATCH] Remove BITS_IN_BYTES define While working on the previous patch, I noticed that BITS_IN_BYTES can be replaced by HOST_CHAR_BIT, which is used more widely in gdb. ChangeLog 2017-08-14 Tom Tromey * valprint.c (print_octal_chars): Use HOST_CHAR_BIT. (print_binary_chars): Likewise.
