From 71cde5e359f273585880ea8986709b950ba85b08 Mon Sep 17 00:00:00 2001 From: David Brownell Date: Thu, 19 Nov 2009 19:02:10 -0800 Subject: target: create/use register_cache_invalidate() Create a generic register_cache_invalidate(), and use it to replace three all-but-identical core-specific routines: - armv4_5_invalidate_core_regs() - armv7m_invalidate_core_regs - mips32_invalidate_core_regs() too. Make cache->num_regs be unsigned, avoiding various errors. Net code shrink and simplification.
