The PA-RISC architecture requires special options for GCC to prevent
linker errors when libraries reach a certain size and / or complexity.
See http://mraw.org/blog/2007/10/10/Linking_on_hppa and gcc
documentation on -mlong-calls.
When testing CMAKE_<LANG>_COMPILER_ID values, do not explicitly
dereference or quote the variable. We want if() to auto-dereference the
variable and not its value. Also replace MATCHES with STREQUAL where
equivalent.
f21ac16e Replace MATCHES test on numbers with EQUAL test
7eacbaed Replace MATCHES ".+" tests with NOT STREQUAL ""
3a71d34c Use CMAKE_SYSTEM_NAME instead of CMAKE_SYSTEM where sufficient
b0b4b460 Remove .* expressions from beginning and end of MATCHES regexs
5bd48ac5 Replace string(REGEX REPLACE) with string(REPLACE) where possible
2622bc3f Clean up usage of if(... MATCHES regex) followed string(REGEX REPLACE regex)
Workaround binutils bug by only marking unique section starting by
".text._".
This adds the HPPA workaround improved in commit b22a0f15 (bootstrap:
improve ld flag for Linux/HPPA builds, 2014-01-14) not only to the
bootstrap, but also to the normal build.
There is a binutils bug that leads to errors like this:
/usr/lib/gcc/hppa2.0-unknown-linux-gnu/4.6.3/../../../../hppa2.0-unknown-linux-gnu/bin/ld: libCMakeLib.a(cmTarget.cxx.o)(.text+0x12084): cannot reach 00001d28__ZNSspLEPKc@@GLIBCXX_3.4+0, recompile with -ffunction-sections
/usr/lib/gcc/hppa2.0-unknown-linux-gnu/4.6.3/../../../../hppa2.0-unknown-linux-gnu/bin/ld: libCMakeLib.a(cmTarget.cxx.o)(.text+0x12084): cannot handle R_PARISC_PCREL17F for std::basic_string<char, std::char_traits<char>, std::allocator<char> >::operator+=(char const*)@@GLIBCXX_3.4
/usr/lib/gcc/hppa2.0-unknown-linux-gnu/4.6.3/../../../../hppa2.0-unknown-linux-gnu/bin/ld: final link failed: Bad value
Until someone finds out what needs to be fixed in binutils this allows anyone
to compile a working CMake even in debug mode.
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block. This is no longer the preferred style.
Run the following shell code:
for c in else endif endforeach endfunction endmacro endwhile; do
echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed
The commit "Disable Intel CRT deprecation warnings" broke the logic that
disabled MS's CRT deprecation warnings. This fixes the logic to disable
the warnings for both MSVC and Intel.
The Intel Compiler for Windows uses the MS runtime library which
deprecates many C functions. We define _CRT_SECURE_NO_DEPRECATE and
_CRT_NONSTDC_NO_DEPRECATE to disable the deprecation warnings.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
