* android-clang: Fix crash in V4 JITEskil Abrahamsen Blomfeldt2018-05-251-1/+5
| | | | | | | | | | | | | | | | | We would pick an incompatible code path when compiling with clang, using an memfd when creating the memory that we later tried to make executable. This differed from how the memory was made in the canAllocateExecutableMemory() function, thus the problem was not detected ahead of time and we crashed in ExecutableAllocator.h when reaching a Q_UNREACHABLE. Amends 847dfa77e9b5d93f7dbb6b78665f1f86d4431a02. The fix is to simply disable this code on Android.

* | Prospective fix for native ARMv7 and ARM64 buildsSimon Hausmann2017-02-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | Don't try to instantiate the presumed "cross-assembler" twice, and also exclude the Yarr JIT from the devtools build. It requires a loadPtr enabled assembler (disabled in V4_BOOTSTRAP builds) and we don't need the regexp engine.

* | Fix compilation of qmldevtools on Windows when cross-compilingSimon Hausmann2017-02-081-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | The use of wildcards in SOURCES is an unspecified "feature" and it turns out that it doesn't work when doing option(host_build) and cross-compiling. We could use $$files(), but there is no truly good reason for using it for only some directories and not others, so this is now a manual expansion.

* | Include the ARMv7 assembler in the qmldevtools bootstrap buildSimon Hausmann2017-02-019-27/+285
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even when the C++ target is not ARMv7 we want to include it in order to be able to generate QML cache files with code ahead of time. This requires a few changes: * The Jump classes need to move from the AbstractMacroAssembler super-class into the concrete assembler sub-class, in order to use it in specializations. * Some of the template specializations in LinkBuffer for example or for platform dependent operations need to be pre-processor enabled when bootstrapping * The generic loadPtr/addPtr etc. functions need to move to the concrete assemblers to be able to call the correct 32-bit or 64-bit variations. * We need to force what looks like a loss of precision to the compiler in the 32-bit ARMv7 linking code when linking jumps. Finally then we can explicitly instantiate at least QV4::JIT::Assembler for ARMv7 when bootstrapping. Currently only on x86-64 hosts, but that is a temporary limitation.
