| * Intel: Record support for relaxed constexpr by version 18.0.5Brad King2019-01-251-1/+1
| | | | | | | | | | | | Update the special case added by commit f719a13c28 (Features: Add special case to disable relaxed constexpr for Intel 18, 2018-06-04, v3.12.0-rc1~11^2) to record that 18.0.5 fixed the regression.

* | | | CMakeDetermineCompilerABI: pass verbose flag during compilationBrad King2019-01-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Default to the same flag that is used for verbose link information, but provide another internal platform information variable to use a compilation-specific variant. Populate it for CUDA where we use a different compiler for compilation and linking and therefore need different flags. Co-Author: Chuck Cranor <chuck@ece.cmu.edu>
* | | | GHS: Add Compiler ID detectionFred Baksik2019-01-161-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -- Detect GHS compiler and version Detect ARCHITECTURE_ID for PPC / ARM / 86 targets Detect PLATFORM_ID for Integrity and Integrity178 platforms Using defines specified in the documents for the compilers: 201416 PPC / 201754 ARM / 201714 86 -- Fallback C/CXX compiler ID to GHS if not otherwise detected and using GHS MULTI generator Works around issue with some GHS compilers not setting __ghs__ compiler define -- Tweak Compiler ID checking so major id of 002017 is not replaced with 217 -- Prefer try_compile() library targets when testing for working GHS compilers -- Avoid CMake errors if reading past end of file for checking if file is PE executable
* | | | GHS: Use the correct compiler flags for CMAKE_BUILD_TYPEFred Baksik2019-01-162-44/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -- Do not use CMAKE_C_FLAGS_RELEASE flags when CMAKE_BUILD_TYPE is empty if CMAKE_BUILD_TYPE was not set the generator would use Release settings this does not match the documented behavior of CMAKE_BUILD_TYPE -- CMAKE_C_FLAGS_<CONFIG> not used when -kernel is present Fixes issue where CMAKE_C_FLAGS_<CONFIG> is ignored when -kernel option is present as a compiler option When the -kernel option is added to an executable it uses a different set of language flags This does not occur -kernel=<type> is used or if it is added as part of a link flag The variables CMAKE_<LANG>_GHS_KERNEL_FLAGS_<CONFIG> are removed NOTE: By default this only added the flag -ldebug which links in the debugger library. -- Separate compiler options by newlines
* | | | GHS: Update the link line processingFred Baksik2019-01-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -- add missing executable linker libs from: CMAKE_C_STANDARD_LIBRARIES -- add missed transitive link libraries -- add skipped library linker options -- The linker expects -l../relative/path/to/lib.a to be relative to the top-level project Because there can be multiple top-level projects convert the path to an absolute path to target
* | | | GHS: Place build system outputs per target output directivesFred Baksik2019-01-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -- Set output and object file locations -- Suffixes are no longer being forced but will now follow the target properties By default GHS tools have no suffix for executable files so CMAKE_EXECUTABLE_SUFFIX was changed to meet this behavior -- Remove #if 0 blocked out code; it has been replaced. Forcing the -relprog option has been removed from non-kernel executable targets. The default value of this option (if it is even available) is determined by the tool-chain for the specified target and platform (Some tool-chains default to -locatedprogram). The use of -relprog can have unexpected results as it cannot always produce a fully relocated executable. -- Clarify use of CMAKE_BUILD_TYPE to control build configuration
* | | | IAR: Update compiler modules to support AVR systemsEthan Slattery2019-01-154-2/+75
| | | | | | | | | | | | | | | | Fixes: #18557
* | | | XL: Move '-bE' flag earlier so it can be overriddenRob Boehne2019-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, we generate an export list for a shared library and pass that file on the link line. The problem was that it could not be overridden by a target when a specific export file is being used. Multiple `-bE` flags on the link are overridden by subsequent `-bE` flags, so only the last one is used. Fixes: #13282

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Running flang with `-E` now ignores any `-o` option and always prints preprocessed output to stdout. Use shell redirection to place it in a file instead. Fixes: #18497

| * Respect CMAKE_<LANG>_COMPILER_ARG1 in CMAKE_<LANG>_COMPILER_PREDEFINES_COMMANDSebastian Holtermann2018-08-283-3/+21
| | | | | | | | | | | | | | | | | | | | | | AUTOMOC used to fail to generate ``moc_predefs.h`` when ``ccache`` was used as a compiler starter by e.g. configuring a project with the environment variable CXX="ccache g++". The reason was that ``CMAKE_<LANG>_COMPILER_ARG1`` wasn't respected in the definition of ``CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND`` for various compilers. This is fixed by this patch. Fixes #17275.

| * NAG: Pass response files through front-end to the linkerBrad King2018-08-011-0/+1
| | | | | | | | | | | | | | The `nagfor` compiler front-end does not support the `@rspfile` syntax. Use `-Wl,@rspfile` instead to pass it through to the linker. Fixes: #18232
* | XL: Use -qpic for position independent executablesBrad King2018-08-011-0/+1
|/ | | | | | The XL compiler does not have a dedicated "pie" option so use at least `-qpic`. This missing setting was exposed by the `ExportImport` and `PositionIndependentTargets` tests with XL on an ELF platform.

* Features: Add special case to disable relaxed constexpr for Intel 18Brad King2018-06-041-1/+1
| | | | | | | | | | Intel compilers define `__cpp_constexpr` to `200704` even in C++14 mode. This indicates that the `cxx_relaxed_constexpr` feature is not available. However, Intel 17 and above document support for it. In commit v3.8.0~9^2 (Features: Update features for Intel C++ 17.0.2 on UNIX, 2017-03-31) we added a special check for this case. Intel 17 and 19 work. However, Intel 18 does not seem to work and fails our test case. Add a special case to disable the feature for Intel 18.

This enables compiler predefines generation (in AUTOMOC) on all platforms that run gcc (and clang).
