Ubuntu 16.04 would provide better distro compatibility, but we need SDL
in version 2.0.5 or newer to enable resizable window support on Linux.
Pretty soon Ubuntu 20.04 LTS will be released, so targetting previous
LTS release should be enough.
Adds LTO to the CI build for Linux, which bring it as close as possible
to the planned formal release, which will additionally use FDO.
Adds some helper scripts to work with FDO files.
Improves the build notes for how to create and use FDO files.
This will trigger CI jobs automatically when pull-request is
created/updated. Until now we used only push event, as it was enough to
handle all automatic jobs from repository maintainers, but this does not
work for pull requests triggered by external collaborators.
We can't simply turn on new event, as it results in duplicate jobs when
PR is created by maintainer, so additional "if" filter is needed to
prevent duplicates from running. GitHub still shows "empty jobs" in some
parts of UI, but at least they don't run and fight for resources.
Unfortunately, GitHub Actions "if" functionality is fairly limited at
the moment:
- it does not work on workflows, only specific jobs
- it does not support array literals (that's why maintainer list is
passed as a string)
- it can't access workflow env variables (that's why maintainer list is
duplicated)
- it does not support regular expressions
- seems to have problem with using unary "!" operator and nested boolean
expressions…
- … and official documentation is pretty misleading by suggesting it
can do many of those things :(
that's why this "if" line looks like it does and is duplicated in every
workflow.
Clang memory sanitizer needs all linked libraries (including STL) to be
compiled with msan option, otherwise analysis results are practically
unusable.
GCC undefined behaviour sanitizer analysis is already covered by build
running UASAN (undefined behaviour and address sanitizers).
Our macOS release builds are limited to Catalina only, and this OS
officially works only on Ivy Bridge (2012) or newer microarchitecture.
Point GCC to target Nehalen (2008) instead - this should cover also all
possible Hackintoshes or virtual machines.
This commit:
- Adds a separate analysis run against the MIRSA (Motor Industry
Software Reliability Association) criteria, which is extremely
thorough. This tally is not summarized or considered fatal to the
workflow. It runs virtually instantly, and the results are very
interesting; however are too numerous to include in our general
analysis (ie: over 13,000 issues).
- Changes the PVS summary script output to a tally-per-file instead
of trying to summarize the nature of the issue, which was mostly
unhelpful without the full text.
- Adds the full list of possible supressible issue to the report
directory, so if further suppressions are needed then these will be
easy to find and use.
- Adds one dr_flac suppression per the resolution here:
