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.
* Add new `CATCH_CONFIG` option for using `std::getenv`, because PS does not support env vars
* Add PS to platforms that have disabled posix signals.
* Small workaround for PS toolchain bug that prevents it from compiling `std::set` with lambda based comparator.
This includes always compiling the ANSI and None colour
implementations, as they don't need to touch any platform
specific APIs, and removing their respective compile-time
configuration options.
Because the Win32 colour implementation requires Win32-specific
APIs, it is still hidden behind a compile-time toggle,
`CATCH_CONFIG_COLOUR_WIN32` (renamed from `..._COLOUR_WINDOWS`).
The commandline options for colours were also changed. The
option now uses different name, and allows to select between
different implementations, rather than changing whether
the compiled-in colour implementation is used through
"yes/no/default" options.
- NVHPC's implementation of `__builtin_constant_p` has a bug which
results in calls to the immediately evaluated lambda expressions to be
reported as unevaluated lambdas.

- Hence, we disable CATCH_INTERNAL_IGNORE_BUT_WARN for NVHPC Compilers
This commit also strips the old copyright comment header in touched
files, as those will also be replaced with a more standardized and
machine-friendly version.
Ideally, clang-tidy would be smart that if one alias of a warning
is suppressed, then the other one is suppressed as well, but as of
right now, it isn't. This means that for now we have to suppress
both aliases of this warning. Opened upstream issue to fix this:
https://bugs.llvm.org/show_bug.cgi?id=45859
Obviously, ideally clang-tidy would also not warn that we are calling
a vararg function when it is an unevaluated magic builtin, but that
also is not happening right now and I opened an issue for it:
https://bugs.llvm.org/show_bug.cgi?id=45860Closes#1921
Catch assumes std::uncaught_exceptions is available whenever C++17 is
available, but for macOS versions older than 10.12 this is not the case.
Instead of checking the C++ version, use a macro to check whether the
feature is available.
CATCH_INTERNAL_IGNORE_BUT_WARN() introduced with b7b346c triggers
clang-tidy warning 'cppcoreguidelines-pro-type-vararg' for every usage
of assertion macros like CHECK() and REQUIRE(). Silence it via NOLINT
in the '#if defined(__clang__)' block only, as clang-tidy honors those.
The old code caused warnings to fire under MSVC, and Clang <3.8.
I could not find a GCC version where it worked, but I assume that it
did at some point.
This new code causes all of MSVC, GCC, Clang, in current versions,
to emit signed/unsigned comparison warning in test like this:
```cpp
TEST_CASE() {
int32_t i = -1;
uint32_t j = 1;
REQUIRE(i != j);
}
```
Where previously only MSVC would emit the warning.
Fixes#1880
This is both a really big and a really small commit. It is small in
that it only contains renaming, moving and modification of include
directives caused by this.
It is really big in the obvious way of touching something like 200
files.
The new rules for naming files is simple: headers use the `.hpp`
extension. The rules for physical file layout is still kinda in
progress, but the basics are also simple:
* Significant parts of functionality get their own subfolder
* Benchmarking is in `catch2/benchmark`
* Matchers are in `catch2/matchers`
* Generators are in `catch2/generators`
* Reporters are in `catch2/reporters`
* Baseline testing facilities are in `catch2/`
* Various top level folders also contain `internal` subfolder,
with files that users probably do not want to include directly,
at least not until they have to write something like their own
reporter.
* The exact files in these subfolders is likely to change later
on
Note that while some includes were cleaned up in this commit, it
is only the low hanging fruit and further cleanup using automatic
tooling will happen later.
Also note that various include guards, copyright notices and file
headers will also be standardized later, rather than in this commit.
