QML: Sanitize reading environment variables.

2015-10-22T12:40:18+00:00

Where possible, use qEnvironmentVariableIsSet()/
qEnvironmentVariableIsEmpty() instead of checking on the
return value of qgetenv().
Where the value is required, add a check using one of
qEnvironmentVariableIsSet()/Empty().

Use the QmlContext to access properties of the scope object

2015-08-10T01:21:57+00:00

Add some runtime methods to access properties of the scope
object directly (using the QmlContext), and generate proper
code to call those.

Add ability to retrieve and use the QmlContext from our generated code

2015-08-10T01:21:48+00:00

Our generated code (JIT and interpreter) should operate on the
QML context to retrieve QML related things. That's better than
operating on 4 different temps.

So this commit introduces the QML context as a temp in the
code we generate for QML. The next commits will move things over
to use that context with specialized runtime methods instead of
using generic subscript/get calls on the different subobjects.

Get rid of qv4value_inl_p.h and replace it by qv4typedvalue_p.h

This is a cleaner separation and further reduces include dependencies
in the definitions of our basic data structured.

V4: fix regalloc for loops with many life&changing vars.

2015-03-03T10:03:59+00:00

When all registers are in use, and one needs to be spilled, the register
whose use is the furthest in the future will be chosen. What needs to be
taken into account is that any use that can also work from the stack can
be skipped, because it does not require the value to be in a register.

V4: fix phi node use position calculation.

2015-03-03T10:03:56+00:00

As phi-nodes get transformed into moves, and the moves end up right
before the terminator of the basic block of the incoming edge, the
use by that phi-node is the position of that terminator minus one.

However, when checking if uses need a register, this was not taken into
account, resulting in an invalid life-time interval split position
calculation.
