If a config directory did not exist, the ini file was
not saved at all.
Only implemented for targets that support `std::filesystem` or `std::experimental::filesystem`.
These are all the targets except nxdk and iOS (only supported on iOS 13+).
From GCC documentation:
> Perform interprocedural pointer analysis and interprocedural modification and reference analysis.
> This option can cause excessive memory and compile-time usage on large compilation units.
> It is not enabled by default at any optimization level.
Also forces the CMake generation to `make` because `ninja` gets into an
infinite loop for some reason on my laptop.
The locale code used the `forceLocale = "en"` fallback when
the locale was set to English, so switching from English
did not actually change the language.
A PGO'd binary can be built as follows:
1. Build with `-DDEVILUTIONX_PROFILE_GENERATE=ON`.
3. Run the timedemo.
4. Build with `-DDEVILUTIONX_PROFILE_USE=ON`.
By default, the profile directory is at `${HOME}/devilutionx-profile`
Example for the RG99:
```bash
# Build the OPK for profiling data collection:
TOOLCHAIN=/opt/rs90-toolchain Packaging/OpenDingux/build.sh rg99 --profile-generate
# Copy the OPK to RG99:
scp -O build-rg99/devilutionx-rg99.opk rg99:/media/sdcard/apps
# Now, run the OPK. It will run the timedemo instead of the actual game and will take a couple of hours.
# ☕☕☕
# Copy the profiling data from RG99
scp -r -O rg99:/media/data/local/home/devilutionx-profile /tmp/devilutionx-profile
# Build the OPK use the collected profiling data:
TOOLCHAIN=/opt/rs90-toolchain Packaging/OpenDingux/build.sh rg99 --profile-use --profile-dir /tmp/devilutionx-profile
# Copy the resulting binary back to RG99
scp -O build-rg99/devilutionx-rg99.opk rg99:/media/sdcard/apps
```
This is much faster in debug mode than the non-C++17 version.
For example, with timedemo_test in debug mode, `M_Talker` goes from 11%
of the total time to just 3.5%.
The `eof()` does not return true until a failed read attempt.
