strager 5510089d45 Improve build times for debug builds (#1859)
* 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)

N. Kolotov 7e1893db42 Added SIMDJSON_ prefix to STRINGIFY and to NO_SANITIZE_UNDEFINED macros. (#1766) 2021-12-21 09:53:06 -05:00
John Keiser 985dfab2c4 Don't use TARGET unless the target options are *not* specified
This eliminates the possibility of inlining target failures for ondemand

Also makes it so we always compile common architectures needed by simdjson.cpp in simdjson.h, since amalgamation has no way to reason about whether to include / exclude it.

* Make it possible to check that an implementation is supported at runtime.

* add CI fuzzing on arm 64 bit

This adds fuzzing on drone.io arm64

For some reason, leak detection had to be disabled. If it is enabled, the fuzzer falsely reports a crash at the end of fuzzing.

Closes: #1188
