* Jit: fix unary minus for integersErik Verbruggen2017-06-071-0/+9

* Prepare run-time method calling mechanism for cross-compilationSimon Hausmann2017-03-171-1/+1
| | | | | | | | | | | | | | | | | | | The current way of encoding the offsetof() of the method_ members in QV4::Runtime is not portable when cross-compiling from a 64-bit host (where the offsetof would be calculated on) to a 32-bit target (where the offset would be different), or vice versa. In preparation for making this work, this patch first replaces the direct use of the run-time members with use through a void * and an enum for indexing. This gives us some type-safety in some places and will also allow for a translation of the pointer offset from host pointer indexing to target pointer indexes. As a bonus we can avoid going through the engine->runtime indirection in the interpreter altogether and call the static methods right away.

* Prospective fix for native ARMv7 and ARM64 buildsSimon Hausmann2017-02-101-0/+4
| | | | | | | | | | | 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.

* 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.

* V4: Fix JavaScript finally-block executionErik Verbruggen2016-08-101-2/+6
| | | | | | | | | | | | | | | | | | | After moving all runtime functions into the Runtime class and doing indirect function calls, the code generation would always emit code to check for an exception after a call. This is problematic for methods that do not throw, but might be called when an exception is thrown. I.e. in a finally block. This is especially problematic for methods like popScope, the very first runtime method that is called in a finally block. The result was that after popScope, execution was passed over to the exception handler block for that finally block (meaning: the body of the finally block was never executed). The fix is to declare an enumerator in an anonymous enum for each runtime method that indicates if an exception check is needed. The existing ExceptionCheck templates are used to set the value.

* V4: Split arguments/locals from temps.Erik Verbruggen2014-05-231-16/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a couple of reasons to split the temporaries off from the arguments and locals: Temporaries are invisible, and changes to them cannot be observed. On the other hand, arguments and locals are visible, and writes to them can be seen from other places (nested functions), or by using the arguments array. So, in practice these correspond to memory locations. (One could argue that if neither nested functions, nor eval(), nor arguments[] is used, the loads/stores are invisible too. But that's an optimization, and changing locals/arguments to temporaries can be done in a separate pass.) Because of the "volatile" nature of arguments and locals, their usage cannot be optimized. All optimizations (SSA construction, register allocation, copy elimination, etc.) work on temporaries. Being able to easily ignore all non-temporaries has the benefit that optimizations can be faster. Previously, Temps were not uniquely numbered: argument 1, local 1, and temporary 1 all had the same number and were distinguishable by their type. So, for any mapping from Temp to something else, a QHash was used. Now that Temps only hold proper temporaries, the indexes do uniquely identify them. Add to that the fact that after transforming to SSA form all temporaries are renumbered starting from 0 and without any holes in the numbering, many of those datastructures can be changed to simple vectors. That change gives a noticeable performance improvement. One implication of this change is that a number of functions that took a Temp as their argument, now need to take Temp-or-ArgLocal, so Expr. However, it turns out that there are very few places where that applies, as many of those places also need to take constants or names. However, explicitly separating memory loads/stores for arguments/locals from temporaries adds the benefit that it's now easier to do a peep-hole optimizer for those load/store operations in the future: when a load is directly preceded by a store, it can be eliminated if the value is still available in a temporary.
