Add support for sampled PC profiling to FullCPU.
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.
