* Introduce qmake feature use_gold_linkerAllan Sandfeld Jensen2014-07-231-0/+2
| | | | | | | | | | | | | | This patch adds the feature use_gold_linker to use the gold linker that has been part of of GNU binutils since 2008. Gold links C++ libraries much faster and use less memory. The feature is autodetected when building Qt on Linux, but can be disabled in configure. On MingW builds it is default off but can be enabled for cross builds.

* Add link-time optimization support for Clang, GCC and ICCThiago Macieira2014-07-232-5/+54
| | | | | | | | | | | | | | | GCC currently requires fat object files for static libraries, since the linker would otherwise not load the .o file from the archive at all and the linking would fail with a lot of undefined references. Clang on Linux also needs this, but it has no equivalent flag, so enabling LTCG for Clang on static libraries will result in linker error. This commit does not add support for enabling it in configure. It can be enabled on a per-project basis by doing CONFIG += ltcg or by passing -config ltcg to qmake's command-line.

* Add support for CONFIG += c++14Thiago Macieira2014-07-201-0/+17
| | | | | | | | | | | | | | | Most compilers out in the wild still don't support the flag, so we need to compare the version number anyway. This also makes it ready for whenever compilers start supporting -std=c++14, something we should fix for C++11 too. It overrides the CXX11 variable for two reasons: 1) we reuse the mechanics in c++11.prf 2) we avoid c++11.prf overriding the flag if qmake decides to process it later (CONFIG += c++14 is additive) Change-Id: I79b6523fd9017483f2474634d1c09f2fd5ea039d Reviewed-by: Olivier Goffart <ogoffart@woboq.com>

* | Disable the new multipass RCC when doing LTCG/LTOThiago Macieira2014-07-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When LTCG/LTO is enabled, the link-time compilation will not use the data in the object file, but instead the precompiled data in a separate section, which is still blank and may not be recognizable by rcc's second pass. That would result in all resource data being nulls -- and the best case scenario out of that is that QResource concludes that there is no resource (it could be worse). That happens with GCC 4.8's GIMPLE intermediate format: a fat .o file containing GIMPLE would be modified by rcc but GCC would not use the modified data at the link stage, whereas a non-fat .o file would not be recognized at all by rcc and the compilation would abort.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, RCC in "C mode" was meant to bundle small resources into a binary, like help texts or an occasional icon. RCC produces a .cpp file containing the actual data in a char array which is then passed to the compiler and linker as a normal source file. Larger resources should be compiled in RCC's binary mode and loaded at run time. Current Qt Quick use tries to deploy large hunks of data in "C mode", causing heavy compiler/system load. This patch works around the issue by splitting the process into three parts: 1. Create a C++ skeleton, as usual, but use a placeholder array with "easily compilable" (mostly NULs) data instead. 2. Compile the skeleton file. 3. Replace the placeholder data with the real binary data. time (qmake5 ; make clean ; make) takes 1.3 s real time for a 100 MB resource here, and there is still room for improving patching performance if really needed.

It can also turn off precompiled headers by setting that to empty or by CONFIG -= precompile_header.

| * fix too aggressive installation of helper librariesOswald Buddenhagen2014-05-201-3/+3
| | | | | | | | | | | | | | | | | | | | | | of course all helper libraries are built statically, so the criterion is not useful. what is interesting is whether the whole qt configuration is static, as that determines what will happen with the helper library when linking the final "actual" artifacts.

| | | | | | | | | | | | | | | | | | | | | | Move it from bootstrap.pro into qt_module.prf so it will apply to any other bootstrapped libraries, like libQmlDevTools. Variable called "SPLIT_SECTIONS" because -fdata-sections could be added in the future, if it proves to be a benefit.
