For a shared library with VERSION and SOVERSION, FASTBuild pointed both
the namelink and the soname link directly at the real file. Instead,
chain the namelink through the soname link, like the other generators
do.
Fixes: #28153
Add experimental support for SYCL under an experimental gate. The
IntelLLVM and Adaptivecpp compilers are recognized, as well as upstream
Clang with libsycl support.
Fixes: #27219, #27905
Shells may exec the final chained command instead of forking it,
preserving resource usage accumulated from earlier children.
When processMetrics is enabled, append a shell builtin to generated
command chains and scripts for Ninja, Makefiles, and FASTBuild to prevent
this optimization while preserving command exit status.
Encapsulate the shell escaping logic in `cmCommonTargetGenerator` and
represent launchers via a vector of strings (as is done with custom
commands, execute process commands, etc.) to make them easier to work
with.
This facilitates work in a future commit which will reuse this pathway.
Issue: #27598, #27402
Move some target related enumeration types from `cmStateTypes.h` to a
new header, as these really aren't "state" types. Also, make
`TargetType` a strongly-typed enumeration.
The FASTBuild generator puts source files from different subdirectories
into different `FastbuildObjectListNode` instances. This ensures that
files with the same name will not write to the same object file. A unity
bucket can only contain files from a single `FastbuildObjectListNode`
instance, so a side effect of this logic is that unity buckets can only
contain files in the same subdirectory. This change fixes the problem by
skipping the subdirectory check logic for files with unity enabled.
Fixes: #27457
When we pass a PDB output directory to the compiler in a path that
requires quoting, the trailing backslash must be escaped to be parsed
correctly by the compiler, e.g., `cl /Fd"path\with space\\"`. However,
`fbuild` does not parse this correctly when extracting `/Fd`. Work
around that bug by using a trailing forward slash in quotes instead.
`include-what-you-use` diagnostics, in practice, are specific to
the environment's compiler and standard library. Update includes
to satisfy IWYU for our CI job under Debian 13. Some patterns:
* Types named in virtual `override` signatures no longer require
includes since the overridden signature already names them.
* A function argument's type needs to be included even if its constructor
is called only by implicit conversion. For example, constructing a
`std::function` from a lambda now requires `<functional>`.
* Some prior mysterious `<type_traits>` inclusions are no longer required.
Create a single place to store target data to prevent duplication.
This moves `targetType` and `targetLabels` out of the snippet files
and into a target map in the `cmakeContent` file referenced by each
snippet.
Fixes: #27244
We were writing "-deps" alias in the generated file
even if we didn't have any dependencies, which is excessive
and makes FASTBuild do more work then necessary.
Two optimizations here:
1. Remove non-mandatory aliases (I only used them for debugging).
2. Make objects lists' name shorter
Both of those improvements contribute to the decrease of the FASTBuild DB file, since they are getting serialized.
List of changes:
1. Remove unneeded aliases
2. Don't write VS Solution on Apple
3. Use external script to perform clean
4. Fix small bug when empty environment was
resulting in invalid file.
It greatly reduces the size of .fdb file and
makes FASTBuild run much faster in different cases.
