Raw Normal View History

Simplify CMake per-source license notices 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copyright/license notice headers that spell out copyright holder names and years are hard to maintain and often out-of-date or plain wrong.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.

PathScale C/C++/Fortran Compiler Information We add compiler information files Compiler/PathScale-<lang>.cmake to specify PathScale compiler information for C, C++, and Fortran languages. We use a macro in Compiler/PathScale.cmake to consolidate the information common to all languages.

Honor CMAKE_<LANG>_FLAGS[_<CONFIG>]_INIT set in toolchain files Document these variables. Change our convention for setting these variables from: set(CMAKE_C_FLAGS_INIT "...") to string(APPEND CMAKE_C_FLAGS_INIT " ...") so that any value previously set by a toolchain file will be used. Automate the conversion with: sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \ Modules/Compiler/*.cmake Modules/Platform/*.cmake and follow up with some manual fixes (e.g. to cases that already meant to append). Also revert the automated changes to contexts that are not protected from running multiple times.
