* Qml JavaScript code generation cleanupsSimon Hausmann2013-10-201-3/+0
| | | | | | | | | | | | | | | * Run the binding expressions, functions and signal handlers through the V4 codegen _per_ component, and run the isel at the end for the entire file. We need to do per-component codegen because we want to set up the correct id and object scopes, which are different for the root component and anonymous components. * Changed V4IR::Module to allow for the concept of "qml modules" where there is no root function defined. This is a logical consequence of running v4 codegen multiple times with different input but the same V4IR::Module.

* V4: remove inplace operationsErik Verbruggen2013-09-301-99/+73
| | | | | | | | | Inplace operations are expanded when building the IR, so the neither the IR, nor the instruction selection backends or runtime need to handle them. Change-Id: Id01f9544e137dd52364cf2ed2c10931c31ddfff3 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

| * Fix passing of exception table pointers to ARM runtime on unwindingSimon Hausmann2013-09-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our synthetic exception unwind table for ARM is located at (char *)codeStart + function->codeSize; This relies on function->codeSize to contain the number of bytes of instructions the function has, not the size of the MacroAssemblerCodeRef (which contains the size of the entire area). This patch fixes the calculation of function->codeSize and also replaces the QHash for the IR::Function* -> CodeRef mapping in the masm backend with a simple vector that's perfectly sufficient.

* | Beginning of a new qml parserSimon Hausmann2013-09-081-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The goal is to parse QML and JavaScript binding expressions/functions in one go and generate data structures that allow for the parsing to happen in a thread and the instantiation of the object tree in another thread, just reading from the generated data structures. This will replace qqmlcompiler and the VME. This new way of loading QML is currently hidden behind the QML_NEW_COMPILER=1 environment variable. There's lots of work left to fill in the gaps in object construction, Component support, Component.onComplete, error messages, etc. etc. Change-Id: I5e40643cff169f469f0b6ce151584ffee5ca5e90 Reviewed-by: Lars Knoll <lars.knoll@digia.com>

* The fast and the furious, register drift.Erik Verbruggen2013-08-271-26/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enable the register allocator for X86_64 on Linux and MacOS. The implications are: - handle as much as possible with current code with as few changes as possible - temporarily force the register allocator to spill unop/binop arguments to the stack by doing a call in the implementation (as is the current case), so no change is needed here - only have loadThis and loadConst handle registers - have any method that might need to handle registrers actually cope with them - the inline versions of binops are not generated, as they cannot cope with registers. This will change when ISel for binops is added in the next patch. This means that we are still running with the handbrakes on, but allow for full-throttle in certain/limited cases. Note about the changed test: multiplication always returns a Number (double), so the operands are passed as doubles, so __qmljs_mul will return a double. For addition this is different: because it might return a Number or a String, the operands are passed as whatever fits best. So __qmljs_add will return an int when both operands are ints. Hence the change to the tests. Change-Id: If5bd7dffca8f7de5ba45af700b9c7bb568fc74b7 Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>
