We now show the more modern `-S {source}` instead of the old and
undocumented `-H{source}` CMake flag, and also show the available
presets, instead of individually specifying the different testing
options.
Closes#2593
I do not know if checking the tracker name or the tracker's file
part of the location first would provide better results, but
in the common case, the line part of the location check should be
rather unique, because different `SECTION`s will have different
source lines where they are defined.
I also propagated this same check into `ITracker::findChild`,
because this significantly improves performance of section tracking
in Debug builds -> 10% in macro benchmark heavily focused on section
tracking. In Release build there is usually no difference, because
the inliner will inline `NameAndLoc::operator==` into `findChild`,
and then eliminate the redundant check. (If the inliner decides
against, then this still improves the performance on average).
`NameAndLocationRef` is pretty large type, so even in release build,
it is unlikely to be passed in registers. In addition to the fact
that some platforms currently do not allow passing even small types
in register (Windows ABI!!), it is better to pass it as a ref,
effectively passing around a pointer.
This enables its inlining even without LTO, which in turns enables
callers to determine that two StringRefs are unequals with simple
comparison of two numbers, without any function calls.
Catch2 suppresses unused variable and equivalent warnings in a couple
of places, but most importantly, in the declaration of autoRegistrar
in test registry. This warning gets triggered by NVHPC compiler. The
current patch adds three macros, namely:
CATCH_INTERNAL_START_WARNINGS_SUPPRESSION
CATCH_INTERNAL_SUPPRESS_UNUSED_VARIABLE_WARNINGS
CATCH_INTERNAL_STOP_WARNINGS_SUPPRESSION
for the NVHPC Compiler which in particular prevents that warning from
occurring. The compiler is detected completely separately from the
other compilers in this patch, because from what I found out, NVHPC
defines __GNUC__ as well for some reason. (I suspect because it
advertises itself as GNU compatible.)
We also add a condition to make sure that the `__GNUC__` path is not
taken by the NVHPC compiler.
Also split out helpers for testing matcher ranges (types whose
begin/end/empty/etc require ADL lookup, types whose iteration
uses iterator + sentinel pair, etc) into their own file.
