LCC (Elbrus C Compiler) doesn't understand some of
GCC pragmas, despite of declaring itself GCC-aware.
The pragma of subject is the one that forbids vectorizing.
Actually, LCC don't vectorize anything unless explicitly
said to, so this pragma may be safely omitted and thus
not cause an error. This patch does this.
With builds that have many internal library directories or many
external libraries, rpaths can be quite large. The cost of calling
install_name_tool thousands of times can add up to minutes on a build,
especially if virus scanning software is there to help you out. With
this change, instead of deleting and then re-adding an rpath, we ignore
it. Likewise we batch all the rpath adjustment calls into a single command.
Before, installing SCALE (some libraries have 70+ build-time RPATHs that
get deleted, plus up to a dozen external RPATHs from upstream
dependencies that should remain in the binary) would take almost 9
minutes on my laptop, and after this change the installation takes only
30 second.
Add documentation for the configure_package_config_file() and
write_basic_package_version_file() commands.
Update the comment for the installation of those files to allow a
stopping point for the code display.
Issue: #22663
The changes are part of CMP0128.
When the standard level is unset:
* Flags are added if extension mode doesn't match the compiler's default.
Previously logic only worked if LANG_EXTENSIONS was ON. Fixes#22224.
* The full flag is used. Previously CMAKE_LANG_EXTENSION_COMPILE_OPTION was
used. This was only supported for IAR.
Otherwise:
* Avoid adding flags if not necessary per the detected compiler defaults.
* Fixed check for when the requested standard is older. It now matches the
nearby comments.
I reworded the fallback comment as its logic was a bit difficult to wrap my
head around.
Since commit 43d6e5a71f (libuv: misc: add function to get CPU affinity
mask size, 2017-09-06, v3.12.0-rc1~412^2~3) we include `<sys/cpuset.h>`
on several BSD platforms but only use it on FreeBSD.
They all had two sentences describing the same thing. Furthermore, with the
shorter wording the explicit advice to see the property being initialized for
further information seems unnecessary.
Add generic documentation to improve the discoverability of language-specific
ones and to make it possible to refer to them generically from other language
generic documentation.
In commit 8d5f4c4db9 (Xcode: Switch to the "new build system" for Xcode
12 and above, 2020-09-14, v3.19.0-rc1~143^2~7) we accidentally added
code in an `else` block that under the opposite condition by which
the block can be entered. Remove it.
Fixes: #22681
Add a copy of the CTestConfig.cmake from Step 9 into the directory for
Step 8.
Expand the information about the contents of the CTestConfig file and
write a brief explanation of where on CDash to acquire the CTestConfig
file for a specific project.
