* | Mark where we need a write barrier in the JITLars Knoll2017-03-091-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | Separate the loadAddress calls into loadAddressForReading and loadAddressForWriting. In the second case, add an out argument that specifies whether the write will need a barrier. Pass the write barrier type that is required for a store down into the actual store methods.

| | | | | | | | | | | | | | | | | | | | SimpleCallData doesn't need any loca variables, so move it into a separate CallData Heap object. This also allows getting rid of the manual markObjects() implementation for CallContext. Change-Id: I9014eb2f815d3e2fe63a951a9d126c38e8aaa0a3 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* | Avoid one indirection when looking up local variablesLars Knoll2017-03-091-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | Simple CallContext's never have locals, as they get converted to temps in the compiler. For regular CallContext's, local variables always got appended to the callcontext. So there was no need to have an additional indirect pointer to them in the CallContext. This speeds up v8-bench by 1-2%. Change-Id: I3def7ba653aea5bc5761076f398450ae30c62823 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* Include the ARMv7 assembler in the qmldevtools bootstrap buildSimon Hausmann2017-02-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
