* Fix run-time string handling with regards to the new heapSimon Hausmann2014-11-211-4/+1
| | | | | | | | | | | | | | | | | Changed runtimeStrings to be an array of Heap::String pointers instead of indirect String pointers. Later that member along with other GC related members will go into a managed subclass. Meanwhile the generated code no more loads String pointers directly but just passes the index into the run-time strings to the run-time functions, which in turn will load the heap string into a scoped string. Also replaced the template<T> Value::operator=(T *m) with a non-template overload that takes a Managed *, in order to help the compiler choose the non-template operator=(Heap::Base *) overload. This allows removing a bunch of Value::fromHeapObject calls. Change-Id: I20415c0549d33cca6813441a2495976b66d4c00e Reviewed-by: Lars Knoll <lars.knoll@digia.com>

| | | | | | | | | | | | | | | | All constants referring to registers and all constants and functions that do platform specific things with the stack, are all modev into a separate file. Information about how a specific platform register is used by the ABI is also extended and is now captured in the RegisterInfo class. Usage of this information will be extended in subsequent patches. This also fix ARM register usage: - Correct fp register for Thumb mode. - Only push registers that have to be saved and will actually be used from the stack (i.e. do not push r0-r3 in the function prelude).

* V4: Split arguments/locals from temps.Erik Verbruggen2014-05-231-18/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
