From 0543f3876c21499784e5f3624fd74bee30951874 Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Sat, 8 May 2004 22:52:43 +0000 Subject: [PATCH] * vax-tdep.c: Tweak comments. Reorder include files. Don't include "symtab.h", "opcode/vax.h" and "inferior.h". (vax_skip_prologue): Replace calls to read_memory_integer by calls to read_memory_unsigned_integer. (vax_gdbarch_init): Reorder.
