From: Giacomo Travaglini Date: Wed, 17 Oct 2018 16:17:48 +0000 (+0100) Subject: sim: Move paramIn/Out definition to header file X-Git-Tag: v19.0.0.0~1405 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=16bf103ad8e2bfbdf200a0ade11cff17dd33e81d;p=gem5.git sim: Move paramIn/Out definition to header file This patch is moving the definitions of paramIn/Out templates to the header file. In this way we gain: 1) We don't have to do explicit instantiation anymore for user defined types. This spares us from including data type header files into serialize.cc 2) We can overload show/parseParam for BitUnions or any other type that requires special handling when serializing. Just by overloading the two templates we get all the containers' (list, vector, array..) serialization for free 2) gtest: With the idea of adding unit tests for Serializable objects, we can avoid importing serialize.cc and just redefine Serializable methods in the test source, implementing a Serializable stub Change-Id: I45a9bb87d5ef886a3668fd477005cd105f612e36 Signed-off-by: Giacomo Travaglini Reviewed-on: https://gem5-review.googlesource.com/c/13635 Reviewed-by: Gabe Black Maintainer: Andreas Sandberg --- diff --git a/src/sim/serialize.cc b/src/sim/serialize.cc index a03a396b3..095a44c34 100644 --- a/src/sim/serialize.cc +++ b/src/sim/serialize.cc @@ -57,12 +57,8 @@ #include #include -#include "arch/generic/vec_reg.hh" -#include "base/framebuffer.hh" #include "base/inifile.hh" -#include "base/logging.hh" #include "base/output.hh" -#include "base/str.hh" #include "base/trace.hh" #include "debug/Checkpoint.hh" #include "sim/eventq.hh" @@ -75,412 +71,11 @@ using namespace std; -// -// The base implementations use to_number for parsing and '<<' for -// displaying, suitable for integer types. -// -template -bool -parseParam(const string &s, T &value) -{ - return to_number(s, value); -} - -template -void -showParam(CheckpointOut &os, const T &value) -{ - os << value; -} - -// -// Template specializations: -// - char (8-bit integer) -// - floating-point types -// - bool -// - string -// - -// Treat 8-bit ints (chars) as ints on output, not as chars -template <> -void -showParam(CheckpointOut &os, const char &value) -{ - os << (int)value; -} - - -template <> -void -showParam(CheckpointOut &os, const signed char &value) -{ - os << (int)value; -} - - -template <> -void -showParam(CheckpointOut &os, const unsigned char &value) -{ - os << (unsigned int)value; -} - - -template <> -bool -parseParam(const string &s, float &value) -{ - return to_number(s, value); -} - -template <> -bool -parseParam(const string &s, double &value) -{ - return to_number(s, value); -} - -template <> -bool -parseParam(const string &s, bool &value) -{ - return to_bool(s, value); -} - -// Display bools as strings -template <> -void -showParam(CheckpointOut &os, const bool &value) -{ - os << (value ?
