* qcompilerdetection.h: stream-line MSVC feature detectionMarc Mutz2012-08-261-6/+9
| | | | | | | | | | | | | | | | | Reformat the MSVC feature detection to be similar to other compilers, ie. 1. Inside the C++11 features section instead of where the compilers are detected 2. In one block for the compiler, with sub-blocks for the version. However, it's now not 100% compatible with the previous version, since Q_CC_INTEL is now explicitly excluded while before it was implicitly included in the MSVC case. I have no idea whether that matters, since Q_CC_INTEL is handled for itself further up already. Change-Id: Id9e8da0a5394ad5643bcb29493f14bc6e8264c13 Reviewed-by: Olivier Goffart <ogoffart@woboq.com>
* Try to work around GCC 4.6's noexcept bugs, againThiago Macieira2012-08-211-6/+3
| | | | | | | | | | | | | | | | Commit 7315296e9c94c38c842728aed199ac286a3ef174 blacklisted GCC 4.6.0 and 4.6.1 on the grounds that the bug regarding noexcept was fixed in 4.6.2. However, we have evidence of the issue remaining in 4.6.3, so it looks like it was not the issue that the GCC team fixed. For that reason, declare noexcept support in GCC 4.6 fatally broken and enable it only for 4.7. It has been working fine for a month for me on 4.7.1.

* Q_DECL_NOTHROW: stronger and more widely available version of Q_DECL_NOEXCEPTMarc Mutz2012-08-071-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1adca807 defined Q_DECL_NOEXCEPT to be the same as throw() for the Microsoft compiler. However, the two are not equivalent: - C++11 noexcept is defined to call std::terminate() if a noexcept function nevertheless encounters an exception. - MSVC throw() has essentially undefined behaviour in this situation: http://msdn.microsoft.com/en-us/library/wfa0edys%28v=vs.100%29 "Due to code optimizations that might be performed by the C++ compiler [...] if a function does throw an exception, the program may not execute correctly." So define two macros: 1. Q_DECL_NOEXCEPT/Q_DECL_NOEXCEPT_EXPR always have C++11 behaviour. This is expected to be the more efficient implementation if the function can actually throw. 2. Q_DECL_NOTHROW means that the function gives the nothrow guarantee. It is stronger than noexcept, but not all functions that can be marked Q_DECL_NOEXCEPT can be marked Q_DECL_NOTHROW. In general Q_DECL_NOTHROW functions need to use a try/catch block in order to prevent exceptions from leaving the functions, unless you can proove that none of the operations can throw. For the caller, both macros are equivalent: it can be relied on that no exception leaves the function.

| | | | | | | | | | | | This allows code using methods marked Q_DECL_NOEXCEPT to benefit from optimisations before MSVC supports the C++11 keyword. Even MSVC 2012 doesn't have it yet. Using throw() in other compilers is not a good idea because they might actually be implementing the C++ standard -- which is broken.

* QNX: fix compilation with C++11 enabledMarc Mutz2012-07-031-0/+12
| | | | | | | | | | | | | | | | | | | | QNX uses GCC, but by default not libstdc++ as the standard library, but 'libcpp', a Dinkumware-derived implementation that doesn't sport many of the C++11 features, yet. Thus, the compiler detection sets Q_COMPILER_INITIALIZER_LIST, which is true, in a way, but we're lacking stdlib support, so the next \#include <initializer_list> will fail. So, simply don't define Q_COMPILER_INITIALIZER_LIST if we're on QNX and detect a Dinkumware signature (taken from Boost.Config). This is a hot-fix. I'm also preparing a more comprehensive solution (qstdlibdetection.h).

* Add detection for C++11 noexceptThiago Macieira2012-06-291-0/+13
| | | | | | | | | | | | | | | | | The Q_COMPILER_NOEXCEPT feature indicates whether this compiler has support for noexcept. Note that the GCC C++11 status page does not list this feature, but investigation into the source code as well as testing reveals it's supported since GCC 4.6. Also add Q_DECL_NOEXCEPT, to be used to declare that a function throws no exceptions, and Q_DECL_NOEXCEPT_EXPR(x), which declares that the function throws no exceptions if x evaluates to true. In C++98 mode, these macros expand to empty -- the old C++98 and C++03 exception specification is deprecated and considered harmful.

| | | | | | | | | | | | | | We no longer have code doing MMX or 3dNow! on Qt 5, so nothing defines those macros. If nothing defines them, we don't need to undef them.

As for QT_HAVE_ARMV6, this macro is replaced by the sub-arch detection in qprocessordetection.h.
