From 9e3c8de30bafe33f35e4b9e82fb49418941f8cb7 Mon Sep 17 00:00:00 2001 From: Andreas Hansson Date: Fri, 24 Feb 2012 11:45:30 -0500 Subject: MEM: Make port proxies use references rather than pointers This patch is adding a clearer design intent to all objects that would not be complete without a port proxy by making the proxies members rathen than dynamically allocated. In essence, if NULL would not be a valid value for the proxy, then we avoid using a pointer to make this clear. The same approach is used for the methods using these proxies, such as loadSections, that now use references rather than pointers to better reflect the fact that NULL would not be an acceptable value (in fact the code would break and that is how this patch started out). Overall the concept of "using a reference to express unconditional composition where a NULL pointer is never valid" could be done on a much broader scale throughout the code base, but for now it is only done in the locations affected by the proxies. --- src/arch/mips/stacktrace.cc | 12 ++++-------- 1 file changed, 4 insertions(+), 8 deletions(-) (limited to 'src/arch/mips/stacktrace.cc') diff --git a/src/arch/mips/stacktrace.cc b/src/arch/mips/stacktrace.cc index d4548b4bb..bb761a243 100644 --- a/src/arch/mips/stacktrace.cc +++ b/src/arch/mips/stacktrace.cc @@ -55,10 +55,8 @@ ProcessInfo::task(Addr ksp) const Addr tsk; - FSTranslatingPortProxy* vp; - - vp = tc->getVirtProxy(); - tsk = vp->readGtoH(base + task_off); + FSTranslatingPortProxy &vp = tc->getVirtProxy(); + tsk = vp.readGtoH(base + task_off); return tsk; } @@ -72,10 +70,8 @@ ProcessInfo::pid(Addr ksp) const uint16_t pd; - FSTranslatingPortProxy* vp; - - vp = tc->getVirtProxy(); - pd = vp->readGtoH(task + pid_off); + FSTranslatingPortProxy &vp = tc->getVirtProxy(); + pd = vp.readGtoH(task + pid_off); return pd; } -- cgit v1.2.3
