* Set allocated memory to 0 on VxWorksKarim Pinter2025-02-191-0/+5
| | | | | | | | | | | | | | When VxWorks is configured with RTP_MEM_FILL false for performance reasons, then it is not filling the allocated memory to 0, causing the QML engine to crash, because it is expecting that it is filled with 0s. This change handles this scenario by calling memset 0 on the allocated memory. Qt needs to be configured with QT_RTP_MEM_FILL define.

* Support building for Raspberry Pi 1 or ZeroDimitrios Apostolou2023-04-171-0/+1
| | | | | | | | | | | | | | | | | | | | Cross-compiling (using Clang-13) for Raspberry Pi OS on Raspberry Pi 1 and Zero, requires adding "-target arm-linux-gnueabihf" to the compiler flags, which defines macro __ARM_ARCH_6KZ__ to detect for armv6. Fixes error: qtdeclarative/src/qml/../3rdparty/masm/wtf/Platform.h:312:6: error: "Not supported ARM architecture" More details: it turns out that the already checked macro __ARM_ARCH_6ZK__ is a typo with significance because older versions of GCC only had this. On the other hand __ARM_ARCH_6KZ__ (that this patch checks for) is the correct spelling, and it's the only one defined by Clang. Newer versions of GCC define both.

* winrt: Switch to always use VirtualAllocFromAppMaurice Kalinowski2017-02-281-52/+22
| | | | | | | | | | | | | | | | | | In latest versions of Windows, one can use VirtualAllocFromApp also without CodeGeneration flag being set. In conjunction with the new garbage collector that let to the situtation that the gc tried to reserve using VirtualAlloc, then the V4Engine constructor checked for JIT availability and disable JIT. This lead to VirtualAllocFromApp alloced memory could not be used anymore and caused to a crash latest when trying to commit or release. With WinRT 8.1 being removed, we do not need the mem_align version anymore and can stick with VirtualAllocFromApp/Free, with the JIT check only testing VirtualProtectFromApp. Task-number: QTBUG-59198 Change-Id: I57f2259c6a6298b8761d00d3abf2589c30de1f63 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
