* | | Fix passing of exception table pointers to ARM runtime on unwindingSimon Hausmann2013-09-121-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Properly unwind the js stack for generated codeLars Knoll2013-09-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Surround all calls into generated code with a try {} catch {} statement that resets the jstack to the correct position. Like this we properly unwind the js stack in all cases, and can also use stricter assertions in our ScopedCallData, etc. classes to check that the stack is healthy.

* Temporarily collect a map of all functions in the engineSimon Hausmann2013-09-021-0/+5
| | | | | | | | | | | | | | | | At the moment we collect a lot of compilation units (one per binding expression!), which for long running QML accumulates and creates a horrible performance when trying to retrieve back traces. There is work in progress to reduces the number of units down to one per QML file, and then the fixed sorted QVector might proof to be a more efficient data structure for the lookups. But until that code lands, this patch proposes to use a QMap instead for the time being, that tracks all functions. This brings down the qtquickcontrols auto-test run from 2.5 minutes to just under a minute on my machine.

* The fast and the furious, register drift.Erik Verbruggen2013-08-271-253/+435
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
