Run the `clang-format.bash` script to update our C and C++ code to a new
include order `.clang-format`. Use `clang-format` version 6.0.

Add entries in Modules and Modules/Platform to support
Objective-C++ compiler determination and identification.
Add Modules to check Objective-C++ compiler flags, source
compilations, program checks, etc...
Use OBJCXX as the designator of the language, eg:
project(foo OBJCXX)
Add various tests for Objective-C++ language features. Add
tests to preserve C++ handling of .M and .mm files when
Objective-C++ is not a configured language.

Simplify by re-ordering parameters of cmCompiledGeneratorExpression::Evaluate
so that frequently used parameters are before less frequently used parameters.
This allows with little extra arguments to get rid of one Evaluate overload,
which makes it easier to implement the cmGeneratorExpression::Evaluate utility.
The latter would otherwise need four overloads.
|
|
|
|
|
|
| |
The quiet flag is false for all but one call to Evaluate. Make the quiet flag
a setter of cmCompiledGeneratorExpression to be able to remove it from the
Evaluate function signature.

Provide a standardized way to handle the C++ "standard" headers
customized to be used with current CMake C++ standard constraints.
Offer under directory `cm` headers which can be used as direct
replacements of the standard ones. For example:
#include <cm/string_view>
can be used safely for CMake development in place of the `<string_view>`
standard header.

3b2b02825d Source sweep: Replace std::ostringstream when used with a single append

This replaces `std::ostringstream`, when it is written to only once.
If the single written argument was numeric, `std::to_string` is used instead.
Otherwise, the single written argument is used directly instead of the
`std::ostringstream::str()` invocation.

This replaces the code pattern
```
std::vector<std::string> args;
cmExpandList(valueStr, args, ...)
```
with
```
std::vector<std::string> args = cmExpandedList(valueStr, ...)
```

This patch is generated by a python script that uses regular expressions to
search for string concatenation patterns of the kind
```
std::string str = <ARG0>;
str += <ARG1>;
str += <ARG2>;
...
```
and replaces them with a single `cmStrCat` call
```
std::string str = cmStrCat(<ARG0>, <ARG1>, <ARG2>, ...);
```
If any `<ARGX>` is itself a concatenated string of the kind
```
a + b + c + ...;
```
then `<ARGX>` is split into multiple arguments for the `cmStrCat` call.
If there's a sequence of literals in the `<ARGX>`, then all literals in the
sequence are concatenated and merged into a single literal argument for
the `cmStrCat` call.
Single character strings are converted to single char arguments for
the `cmStrCat` call.
`std::to_string(...)` wrappings are removed from `cmStrCat` arguments,
because it supports numeric types as well as string types.
`arg.substr(x)` arguments to `cmStrCat` are replaced with
`cm::string_view(arg).substr(x)`

For each build setting property (such as `COMPILE_DEFINITIONS` or
`INCLUDE_DIRECTORIES`), the value of `$<TARGET_PROPERTY:target,prop>`
includes the values of the corresponding `INTERFACE_*` usage requirement
property from the transitive closure of link libraries of the target.
Previously we computed this by constructing a generator expression
string like `$<TARGET_PROPERTY:lib,INTERFACE_COMPILE_DEFINITIONS>` and
recursively evaluating it with the generator expression engine. Avoid
the string construction and parsing by using the dedicated evaluation
method `cmGeneratorTarget::EvaluateInterfaceProperty`.

In large projects the generation process spends a lot of time evaluating
usage requirements through transitive interface properties on targets.
This can be seen in a contrived example with deep dependencies:
set(prev "")
foreach(i RANGE 1 500)
add_library(a${i} a.c)
target_compile_definitions(a${i} PUBLIC A${i})
target_link_libraries(a${i} PUBLIC ${prev})
set(prev a${i})
endforeach()
For each usage requirement (such as `INTERFACE_COMPILE_DEFINITIONS` or
`INTERFACE_INCLUDE_DIRECTORIES`), the value of the generator expression
`$<TARGET_PROPERTY:target,prop>` includes the values of the same
property from the transitive closure of link libraries of the target.
Previously we computed this by constructing a generator expression
string like `$<TARGET_PROPERTY:lib,INTERFACE_COMPILE_DEFINITIONS>` and
recursively evaluating it with the generator expression engine. Avoid
the string construction and parsing by creating and using a dedicated
evaluation method `cmGeneratorTarget::EvaluateInterfaceProperty` that
looks up the properties directly.
Issue: #18964, #18965
|
| |
|
|
|
|
|
| |
Check for usage requirement properties early enough to avoid duplicate
checks in other conditions.

An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.

This allows for expressions such as:
$<COMPILE_LANG_AND_ID, CXX, GNU, Clang>
|
| |
|
|
|
|
|
| |
This allows for expressions like:
$<$<CXX_COMPILER_ID:Clang,GNU>:-DMY_PRIVATE_DEFINE>
|
|
|
|
|
|
|
|
|
|
|
| |
For special properties like `INCLUDE_DIRECTORIES`, the pointer returned
by `cmTarget::GetProperty` is only valid until the next time the same
special property is queried on *any* target. When evaluating a nested
`TARGET_PROPERTY` generator expression we may look up such a property
more than once on different targets. Fix `TargetPropertyNode::Evaluate`
to store the lookup result in locally owned memory earlier.
