The Clang scanbuild tool warns:
Utilities/cmliblzma/liblzma/simple/x86.c:106:23: warning:
The result of the '<<' expression is undefined
src = dest ^ ((1u << (32 - i * 8)) - 1);
~~~^~~~~~~~~~~~~~~
AFAIK overflow of a left shift on an unsigned type is well-defined.
We first suppressed this in commit v3.1.0-rc1~647^2 (CTestCustom:
Suppress warnings about rand() and srand() on OpenBSD, 2014-04-12).
Add another variant of the warning wording.
Our `cmake.version.manifest` file uses a "compatibility" element for
Windows 10 support. Older MS tools warn about it being unknown, so
suppress the warning.
Use clang-tidy's performance-unnecessary-copy-initialization checker.
After applying the fix-its (which turns the copies into const&), revise
the changes and see whether the copies can be removed entirely by using
the original instead.
Use clang-tidy's performance-unnecessary-value-param checker to find
value parameter declarations of expensive to copy types that are not
modified inside the function. Ignore findings in kwsys.
After applying the fix-its, manually change `const T&` to `T const&`.
d256ba07 try_compile: Optionally forward custom platform variables to test project
fb4791b3 cmCoreTryCompile: Refactor forwarding of variables to test project
OS X supports using the SDK for any version equal to or newer than
the deployment target. There is no reason to warn if the versions
do not match exactly.

Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list
of custom variables to be forwarded to a `try_compile` test project.
This will be useful for platform information modules or toolchain files
to forward some platform-specific set of variables from the host project
(perhaps set in its cache) to the test project so that it can build the
same way.
De-duplicate the logic that constructs the cmake `-D` flag used to pass
variables into the test project cache. Also subsume variables that were
propagated by generating `set()` commands in the project and pass them
as cache entries instead.
5784747d Improve string find: prefer character overloads.
5cec953e Use std::replace for replacing chars in strings.
2a1a2033 cmExtraEclipseCDT4Generator: use std::replace.
34bc6e1f cmCTestScriptHandler: don't call find repeatedly.
c1340827 Add a variable to specify language-wide system include directories
44199097 cmMakefile: Optimize AddSystemIncludeDirectories for empty set
a896043b GHS: Compute include directories consistently with other generators
Follow the configure_file by a file(GENERATE) so the resulting cmake
scripts used by FindCUDA for wrapping nvcc calls can now support
generator expressions in the CUDA_NVCC_FLAGS variable.
Create a `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` variable to specify
system include directories for for `<LANG>` compiler command lines.
This plays a role for include directories as the existing
`CMAKE_<LANG>_STANDARD_LIBRARIES` variable does for link libraries.
