* findclasslist.pl: match unexported classes tooThiago Macieira2022-09-061-3/+11
| | | | | | | | | | | | | Unexported structs do mark private API too. This change necessitated fixing the negative-lookahead, because otherwise we'd match a line like: class QVariant; With $1 = "QVarian" and the "t" stood for the negative lookahead.

* wasm: set ALLOW_MEMORY_GROWTH for multi-threaded buildsMorten Sørvig2022-09-011-16/+3
| | | | | | | | | | | | | | | | | | | | Unify the settings for single-threaded and multi-threaded builds; Qt now always enables heap growth by default. This means we don't have to reserve a large (1GB) fixed memory size, but can instead set the smaller (50 MB) initial memory size, like the single-threaded build does. Enabling threads + memory growth can potentially cause a performance regression when accessing heap memory from JavaScript (https://github.com/WebAssembly/design/issues/1271). We leave it for the application to decide if this applies, and if the switch to fixed memory should be made.

* wasm: include asyncify support unconditionallyMorten Sørvig2022-08-171-3/+3
| | | | | | | | | | | | | | | | | | | Emscripten's option for enabling asyncify (-sASYNCIFY) is a link-time option, which means there is no requirement to have a separate asyncify build, at least for static builds. Replace the current QT_HAVE_EMSCRIPTEN_ASYNCIFY compile-time option with a run-time option which checks if the asyncify API is available. Keep support for configuring with "-device-option QT_EMSCRIPTEN_ASYNCIFY=1" for backwards compatibility and for the use case where want asyncify support to be on by default for a given Qt build. Enable asyncify for the asyncify_exec example. Pick-to: 6.4 Change-Id: I301fd7e2d3c0367532c886f4e34b23e1093646ad Reviewed-by: Tor Arne Vestbø <tor.arne.vestbo@qt.io>

* Add new mkspecs device for Raspberry Pi 4 (64-bit)Umair Raihan2022-07-142-0/+33
| | | | | | | | | | | | | | | The existing mkspecs for Raspberry Pi 4 (devices/linux-rasp-pi4-v3d-g++) was intended to compile Qt application for the 32-bit version of Raspberry Pi, thus it used compiler flags that are incompatible when compiling Qt application for the ARM 64-bit architecture. According to ARM compiler documentation, -mfpu flag is rejected by AArch64 state while its alternative, -mcpu, has to be avoided when -march flag is already defined. -mfloat-abi flag is not valid with AArch64 targets. To support both 64-bit and 32-bit architectures, I proposed to add this new mkspecs.

* wasm: don't enable specialHTMLTargets by defaultMorten Sørvig2022-06-011-1/+1
| | | | | | | | | | | | | | | | | | Adding specialHTMLTargets to EXPORTED_RUNTIME_METHODS carries the obligation to actually use it as well; failing to do so makes Emscripten stop with a reference error on startup. However, we can't guarantee that Qt will use it in all cases. The current usage depends on QGuiApplication being used. Application code could be using QCoreApplication, or no application object at all. Detect if specialHTMLTargets is present instead, and then enable the code paths which uses it if that's the case. This means that apps which want to use e.g. multiple browser windows can opt into support by making sure EXPORTED_RUNTIME_METHODS contains specialHTMLTargets.

* Enable -mno-direct-extern-access and ELF protected visibilityThiago Macieira2022-03-103-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The -mno-direct-extern-access tells the compiler and linker that references to symbols outside this ELF module mustn't be direct and must instead always go through the GOT or PLT (the PLT can additionally be disabled with -fno-plt). The ELF protected visibility tells the compiler and linker that this symbol is present in the dynamic symbol table as an export, but it cannot be interposed by another ELF module. This option is required for user code to link properly to Qt, otherwise they will get linker errors (assuming GNU binutils >= 2.39) or runtime failures (glibc >= 2.35). Both versions of glibc and binutils are older than GCC 12, so it's a safe assumption they are in use and downgrading the toolchain or libc is not supported. Adding this option to the compilation is assured for CMake and qmake-based projects. For example, all accessess to QCoreApplication::self in QtCore, after this change and with GCC 12 are relocation-free and direct: 000000000013ebf0 <QCoreApplicationPrivate::checkInstance(char const*)>: 13ebf0: cmpq $0x0,0x4f73d0(%rip) # 635fc8 <QCoreApplication::self> 13ebf8: setne %al 13ebfb: je a90fe <QCoreApplicationPrivate::checkInstance(char const*) [clone .cold]> 13ec01: ret Meanwhile, accesses to the same variable in other modules are indirect via the GOT: 66650: mov 0x876e1(%rip),%rax # edd38 <QCoreApplication::self@Qt_6> 66657: cmpq $0x0,(%rax) This replaces the -Bsymbolic and -Bsymbolic-functions (broken) functionality that Qt has been using or attempting to use since ~2006.

* qmake: Allow using Windows 10 API in MinGW qmake internal projectsAlexandru Croitor2022-01-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to build qt3d examples with qmake and MinGW in the CI, compilation would fail with errors like In file included from C:/MINGW1120/mingw64/x86_64-w64-mingw32/include/windows.h:72, from C:\Users\qt\work\qt\qt3d\examples\qt3d\simple-cpp\main.cpp:63 include/winuser.h:2965:72: error: 'POINTER_INPUT_TYPE' was not declared in this scope What happens is that calling qmake on examples.pro loads qt3d/.qmake.conf, which then loads qt_build_config.prf which then defines the following definitions: mingw: DEFINES += WINVER=0x0601 _WIN32_WINNT=0x0601 This limits usage of Windows API up to Windows 7, with later APIs being unavailable. Most .qmake.conf files were removed in qt repos, but We didn't remove the .qmake.conf file (fb656c036db0549180073e133773862d08f6cd24) for qt3d because it's supposed to be buildable with CMake + Qt 6 as well as qmake + Qt 5. Bump the defines to the same Windows 10 version we use everywhere else when building with CMake.
