Simple text list of symbol (or address) and count will be dumped to m5prof.<cpu-name> if the cpu's pc_sample_interval param is set. SConscript: Add cpu/full_cpu/pc_sample_profile.cc base/callback.hh: Add a comment about MakeCallback. Fix type in another comment. base/loader/symtab.cc: Revamp findNearestSymbol() to provide addresses of both nearest symbols (preceding and following) as well as string for former. Move global definition of debugSymbolTable here too. base/loader/symtab.hh: Revamp findNearestSymbol() to provide addresses of both nearest symbols (preceding and following) as well as string for former. Move global declaration of debugSymbolTable here too. cpu/exetrace.cc: Use new findNearestSymbol() interface for trace symbols. kern/linux/linux_system.cc: sim/system.cc: Remove extern of debugSymbolTable (now in symtab.hh) sim/process.cc: Initialize debugSymbolTable if binary has a symbol table. --HG-- extra : convert_revision : 0b5393dc39c40ac88c953684708f1125da550671
