Some deployments of GCC won't link ASAN build without explicitly
specifying the library, and report:
"ASan runtime does not come first in initial library list;
you should either link runtime to your application or
manually preload it with LD_PRELOAD"
This commit includes the asan library by default for respective
builds.
The 'optinfo' build target asks GCC to print optimizations that
could not be performed to local 'missing.txt' files; these will
appear in each repsective subdirectory having source files.
Both GCC and Clang will now print Verbose vectorization information
during the build process, often describing why vectorization
cannot be performed.
This commit also enables basic instruction and math vectorization
for both the 'release' and 'optinfo' targets. This includes making
use of altivec instructions (available on all powerpc processors),
and at a minimum sse4.2 on all x86_64 processors (circa-2008+ AMD
and Intel CPUs).
Vectorization is also re-enabled for GCC FDO builds, which would
otherwise be disabled when we switch to -O2 optimizations.
Set AllowAllConstructorInitializersOnNextLine to false. This prevents
formatting problem when initializer list is long enough to be wrapped
once, but all initializers fitted into the next line.
Turn on AlignConsecutiveMacros option.
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 script is intended to be used in two situations:
- When user can't configure clang-format in code editor or IDE
- Potentially to be used in CI in the future
Normal usecase is to run this script after commit, then review and
add formatted code, and amend the commit, e.g.:
git commit -m "Edit some C++ code"
./scripts/format-commit.sh
git add -p # select formatting changes you want to use
git commit --amend
Run:
./scripts/format-commit.sh --help
to learn about other options.
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:
mackron/dr_libs#117
Users, who try to compile keep tripping over it, despite documentation
in the INSTALL file. Also, autoconf-archive might be hard to install
for users, who opted not to use MSYS2 and stick to MinGW only.
This commit bundles macros:
AX_CXX_COMPILE_STDCXX (version/serial 10)
AX_CXX_COMPILE_STDCXX_11 (version/serial 18)
When using C++11 code that can possibly throw exceptions (such as
std::make_shared(...) linking libstdc++.a using Clang on MSYS2
will generate errors such as:
libstdc++.a(eh_personality.o): duplicate section
`.rdata$_ZTSSt9exception[_ZTSSt9exception]' has different size
Although potential suggested fixes involve allowing duplicate symbols,
-Wl,--allow-multiple-definition, this solution can introduce unexpected
behavior when one symbol clobbers another symbol.
To solve this, switching to dynamic linking of the libstdc++ library
appears to be all that's needed.
Also re-order to perform shellcheck first because it
requires the least installation work compared to pylint
and markdownlint. The reason being if we're going to fail
during shellcheck, then we fail faster (and leave heavier
tasks for further down the line).
Use the exact formatting suggested in COPYING file.
This change is basically a pretext to trigger a new clean build in
order to check if Coverity is capable of accepting new builds for
analysis finally.
