Related to #1904
Users of the simdjson library will see json2msgpack as an available
example of how to recursively process json with the ondemand parser,
and checking for trailing tokens in a document is one part of json validation.
These checks shouldn't affect benchmark results performance.
The benchmark is run on the 631KB twitter.json file.
Load 2 bytes and compare the 2 bytes against `"\u"`
Compilers with optimizations turned on will turn this into a 16-bit load
then 16-bit compare on supported platforms
(with smaller compiled code size).
Make it obvious to the compiler that it's reading two
consecutive bytes of the same pointer
Add parse_surrogate_pairs to show the difference exists.
See discussion in #1896
* Rename simdjson_really_inline -> simdjson_inline
I want to change the simdjson_really_inline macro to sometimes not force
inlining. After that upcoming change, the name simdjson_really_inline
will no longer makes sense.
Rename simdjson_really_inline to simdjson_inline. This patch should not
change semantics; simdjson_inline still forces inlining as before.
Some functions still need to be really inlined for ABI reasons.
(GCC's -Wpsabi complains otherwise.) Leave those functions marked as
simdjson_really_inline.
* Improve build times for debug builds
simdjson_inline is used for most simdjson functions. It forces inlining.
In unoptimized/debug builds, this can lead to a lot of machine code
being generated (especially with Address Sanitizer), causing slow
compilation.
Change simdjson_inline to force inlining only for optimized builds.
Sometimes, the programmer might want a slightly-optimized build and want
fast compilation (e.g. GCC's -Og mode). Allow simdjson users to define
the simdjson_inline macro themselves (e.g. on the command line:
-Dsimdjson_inline=inline) in cases where the default behavior is
undesired.
This patch reduced build times by over 75% for ondemand_object_tests.cpp
with GCC 9.4.0 and CMAKE_BUILD_TYPE=Debug on my AMD 5950X:
Before: 6.885 6.683 6.971 6.957 6.949 seconds (5 samples)
After: 1.492 1.551 1.494 1.490 1.531 seconds (5 samples)
* Patch for possible AVX-512 overflow.
* Updating the test for new padding.
* Preparing new version.
* replace binary integer literals with hex literals for C++11 compatibility (#1855)
Binary integer literals are a C++14 feature, so those are not supported
in C++11 and should be replaced by hexadecimal literals instead.
Fixes#1854.
Co-authored-by: Dirk Stolle <striezel-dev@web.de>
* Let us time minify
* Making AVX-512 available by default.
* Silencing some maybe-uninitialized warning under GCC (warning appears in the standard library).
* Making the Python amalgamation script a bit more Windows friendly.
* We do not try to silence -Wmaybe-uninitialized under clang.
Including <iostream> has two problems:
* Compile times are worse because of over-inclusion
* Binary sizes are worse when statically linking libstdc++ because
iostreams cannot be dead-code-stripped
simdjson only needs std::ostream. Include the header declaring only what
we need (<ostream>), omitting stuff we don't need (std::cout and its
initialization, for example).
This commit should not change behavior, but it might break users who
assume that including <simdjson/simdjson.h> will make std::cout
available (such as many of simdjson's own files).
* Adding test.
* Verifies and fix issue 1668. This commit updates the previous behavior of the
On Demand stream support by return a value type (document_reference) instead
of a reference to a document. This allows us to bridge with the usually simdjson
error system, with its simdjson_result types.
