From ecf1eb72489524c54897275c6ea314fe500c2b7d Mon Sep 17 00:00:00 2001 From: Vincentius Robby Date: Thu, 31 May 2007 16:01:41 -0400 Subject: Assign traceData to be NULL at BaseSimpleCPU constructor. Initialize a temporary variable for thread->readPC() at setupFetchRequest() to reduce function calls. exec tracing isn't needed for m5.fast binaries Moved MISCREG_GL, MISCREG_CWP, and MISCREG_TLB_DATA out of switch statement and use if blocks instead. src/arch/sparc/miscregfile.cc: Moved MISCREG_GL, MISCREG_CWP, and MISCREG_TLB_DATA out of switch statement and use if blocks instead. src/cpu/simple/base.cc: Assign traceData to be NULL at BaseSimpleCPU constructor.
