Matthias Kretz 9b4e4c92ae Improve checks for Open64 and g++ incompatible flags (#12119) 2012-02-12 10:42:54 +01:00
Brad King 646cf91932 CheckCCompilerFlag: Generalize "but not for C" case (#12633)
The "warning: " part is not necessary.  The case can happen on any GNU
compiler, not just an Apple version.

Brad King ed6be501de Fix CHECK_(C|CXX)_COMPILER_FLAG for Clang (#12394)
This compiler warns and returns 0 for unrecognized flags.  We fix the
compiler flag check macros by looking for a warning in the output.

David Cole b7f3f7cdb6 Add fail regex to detect supported warning flags correctly.
On Apple's gcc, the compiler emits a warning such as "warning: command
line option "-Wno-deprecated" is valid for C++/ObjC++ but not for C"
when it is passed that flag on its command line.

When testing for that flag with a plain C file, we should report that
the flag is unsupported for C files. The new FAIL_REGEX option added
here produces this behavior.

Brad King b3efdb58d5 CheckCCompilerFlag: Strict signature of 'main' (#11615)
Use "int main(void)" instead of just "int main()" so that compiling with
"gcc -Werror=strict-prototypes" works.  Test this check using the flags
"-Werror -Wstrict-prototypes" to work with old GCC versions.

Brad King 3a666595c9 Convert CMake non-find modules to BSD License
This adds copyright/license notification blocks CMake's non-find
modules.  Most of the modules had no notices at all.  Some had notices
referring to the BSD license already.  This commit normalizes existing
notices and adds missing notices.

Brad King 83957d9e0d Fix CHECK_(C|CXX)_COMPILER_FLAG for XL and SunPro
These compilers warn and return 0 for unrecognized flags.  We fix the
compiler flag check macros by looking for a warning in the output.  We
also update the regex for GNU on older Macs.  See issue #9516.

Brad King 80af3ae35d Cleanup generic compiler check macro documentation
This commit improves formatting and style of the documentation for the
general-purpose compiler check macros:

  CHECK_C_COMPILER_FLAG
  CHECK_C_SOURCE_COMPILES
  CHECK_C_SOURCE_RUNS
  CHECK_CXX_COMPILER_FLAG
  CHECK_CXX_SOURCE_COMPILES
  CHECK_CXX_SOURCE_RUNS

This sytle is more consistent with CMake command documentation.
It also looks nicer in the generated documentation text files.
