* Autogen: Iterate source files only onceSebastian Holtermann2017-09-071-1/+3
| | | | | | | | | | | | | | This is a large commit that serves multiple purposes - Iterate source files only once and store all extracted information in a cmQtAutogenDigest class that can be reused. This is brings speed improvements because several properties are only evaluated once. More that that it helps to avoid duplication of code with non trivial files property checks. - Fix the Visual Studio generator to use PRE_BUILD when possible. - Convert `for( ... )` loops to C++11 range base loops where possible (cmQtAutogen*.cxx only). - String concatenation optimizations.

| * Add policy CMP0069 to enforce INTERPROCEDURAL_OPTIMIZATIONRuslan Baratov2017-03-301-0/+2
| | | | | | | | | | | | | | | | | | Previously the `INTERPROCEDURAL_OPTIMIZATION` target property was honored only for the Intel compiler on Linux and otherwise ignored. In order to add support for more compilers incrementally without changing behavior in the future, add a new policy whose NEW behavior enforces the `INTERPROCEDURAL_OPTIMIZATION` property. Add flags for supported compilers and otherwise produce an error.

* Xcode: Control emission of EFFECTIVE_PLATFORM_NAMEGregor Jasny2017-01-201-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building with multiple SDKs within one project Xcode requires the usage of ${EFFECTIVE_PLATFORM_NAME} to put temporary and build outout into separate directories. For example an iOS device and simulator build use two different SDKs (iphoneos and iphonesimulator). In the past cmake tries to detect embedded toolchains that could possibly use simulators and emitted EFFECTIVE_PLATFORM_NAME (EPN) at the proper locations. In #16253 Mark noticed that if he uses macosx and iphoneos in combination the necessary EPN is not emitted. This is because CMake by default assumes macosx SDK which does not trigger EPN emission. The fist naive approach - enabling EPN unconditionally revealed that then the EPN leaks into generator expressions like $<TARGET_FILE:xxx> which might be a regression and thus is unacceptable. The next approach was to add an CMake property to enable EPN emission unconditionally. This solved the reported problem. But the EPN leakage also happened for the embedded toolchains already without anyone noticing. So the control property was turned into a tri-state one: * No definition: EPN is activated for embedded toolchains like before * ON: EPN is always emitted * OFF: EPN is never emitted That approach gives the user the chance to disable EPN for embedded toolchains and restores generator expression functionality for those. Closes: #16253

* cmLinkLineComputer: Move ComputeLinkLibs from cmLocalGeneratorStephen Kelly2016-10-101-2/+3
| | | | | | | | | | | | | | | Add a cmOutputConverter to the cmLinkLineComputer and factory methods to facilitate shell escapes. Add state to the cmLinkLineComputer to record whether outputting for response files or for watcom, to satisfy the cmOutputConverter API. These are constant for the lifetime of the cmLinkLineComputer, even when its functionality is extended in the future. This also keeps the signatures of cmLinkLineComputer relatively simple. Pass the cmComputeLinkInformation as a method parameter so that cmLinkLineComputer is free from target-specific state. An instance should be usable for all targets in a directory.
* cmLinkLineComputer: Extract from cmLocalGeneratorStephen Kelly2016-10-101-0/+7
| | | | | | | | | | | CMake has several classes which have too many responsibilities. cmLocalGenerator is one of them. Start to extract the link line computation. Create generator-specific implementations of the interface to account for generator-specific behavior. Unfortunately MSVC60 has different behavior to everything else and CMake still generates makefiles for it. Isolate it with MSVC60-specific names.

* | cmGlobalGenerator: Add API to get settings from top-level cmMakefileStephen Kelly2016-10-061-0/+4
|/ | | | | | | | | | | | | | | | | | | | | | | | | At generate-time, definitions are sometimes read from a nearby cmMakefile, making the value directory-specific because they are read once per directory. Often however, the intention is more often to create a 'global' setting, such that the user writes for example: set(CMAKE_IMPORT_LIBRARY_SUFFIX something) once at the top level of their project. Many of these are also set by internal platform files, such as CMAKE_EXTRA_LINK_EXTENSIONS. The set() definitions are not really suitable for 'global' settings because they can be different for each directory, and code consuming the settings must assume they are different for each directory, and read it freshly each time with new allocations. CMake has other variable types which are global in scope, such as global properties, and cache variables. These are less convenient to populate for users, so establish a convention and API using the value as it is at the end of the top-level CMakeLists file.
* Simplify CMake per-source license noticesBrad King2016-09-271-12/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Per-source copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong. Precise contributor information is already maintained automatically by the version control tool. Ultimately it is the receiver of a file who is responsible for determining its licensing status, and per-source notices are merely a convenience. Therefore it is simpler and more accurate for each source to have a generic notice of the license name and references to more detailed information on copyright holders and full license terms. Our `Copyright.txt` file now contains a list of Contributors whose names appeared source-level copyright notices. It also references version control history for more precise information. Therefore we no longer need to spell out the list of Contributors in each source file notice. Replace CMake per-source copyright/license notice headers with a short description of the license and links to `Copyright.txt` and online information available from "https://cmake.org/licensing". The online URL also handles cases of modules being copied out of our source into other projects, so we can drop our notices about replacing links with full license text. Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority of the replacements mechanically. Manually fix up shebang lines and trailing newlines in a few files. Manually update the notices in a few files that the script does not handle.
* cmGlobalGenerator: Optimize FindMakefile method with an indexBrad King2016-09-261-0/+10
| | | | | | | This method is used by directory get/set APIs. With the new `SUBDIRECTORIES` and `BUILDSYSTEM_TARGETS` methods projects may now make heavy use of these APIs to traverse their directory structure and process targets. Make this faster by indexing the directory lookups.
* Ninja: Refactor Fortran rejection logicBrad King2016-09-221-0/+2
| | | | | | | | | Delay rejection of Fortran until after we've determined the version of the `ninja` tool to be used. This will later allow us to enable Fortran support based on the version of ninja. While at it, make the rejection an immediate fatal error. Also provide a stack trace so readers know what code tried to enable Fortran.
* cmGlobalGenerator: Refactor global target constructionBrad King2016-09-151-11/+24

* cmGlobalGenerator: Split CreateDefaultGlobalTargets implementationBrad King2016-09-151-0/+6

* Format include directive blocks and ordering with clang-formatBrad King2016-04-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sort include directives within each block (separated by a blank line) in lexicographic order (except to prioritize `sys/types.h` first). First run `clang-format` with the config file: --- SortIncludes: false ... Commit the result temporarily. Then run `clang-format` again with: --- SortIncludes: true IncludeCategories: - Regex: 'sys/types.h' Priority: -1 ... Commit the result temporarily. Start a new branch and cherry-pick the second commit. Manually resolve conflicts to preserve indentation of re-ordered includes. This cleans up the include ordering without changing any other style. Use the following command to run `clang-format`: $ git ls-files -z -- \ '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' | egrep -z -v '(Lexer|Parser|ParserHelper)\.' | egrep -z -v '^Source/cm_sha2' | egrep -z -v '^Source/(kwsys|CursesDialog/form)/' | egrep -z -v '^Utilities/(KW|cm).*/' | egrep -z -v '^Tests/Module/GenerateExportHeader' | egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' | xargs -0 clang-format -i This selects source files that do not come from a third-party.
