While doing my recent optimization work, it became useful to have an
idea of the time different parts of the processing pipeline are
taking.
This patch introduces an abigail::tools_utils::timer type that is easy
to use to time a given part of the code and emit the elapsed time to
an output stream.
This abigail::tools_utils::timer type is thus used to time various
parts of the processing pipeline involved in abidw. Just using the
existing --verbose option now yields timing information.
* include/abg-tools-utils.h (class timer): Declare new type.
(operator<<(ostream&, const timer&)): Declare new streaming
operator for the new timer type.
* src/abg-tools-utils.cc (struct timer::priv): Define new type.
(timer::{timer, start, stop, value_in_seconds, value,
value_as_string, ~timer}): Define member functions.
(operator<<(ostream& o, const timer& t)): Define streaming
operator.
(build_corpus_group_from_kernel_dist_under): Add timing logs to
the linux kernel reading process.
* src/abg-dwarf-reader.cc
(read_context::canonicalize_types_scheduled): Add timing logs to
type canonicalization.
(read_debug_info_into_corpus): Add timing logs for the whole debug
info loading and internal representation building process.
* tools/abidw.cc (load_corpus_and_write_abixml): Add timing logs
for the binary loading and serizalization process.
(load_kernel_corpus_group_and_write_abixml): Add timing logs the
Linux Kernel binary loading and writing process.
