| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both MIPS and X86-64 on Windows reserve space for four registers on the stack, that the called function may use to spill the parameters passed in registers. This needs to be handled without #ifdefs in order to support cross-compilation and from the looks of it it was also wrong on MIPS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our two value encodings use different masks for the upper 4 bytes. Depending on the target architecture we must use different values when generating code that uses these masks. This patch replaces the #ifdef'ed ValueTypeInternal_* enum values with two C++11 scoped enums that allows for the co-existence of both throughout the code base as well as selective use in the code generators.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

By ensuring that the members are stored at pointer intervals, we can translate from host pointer size to target when generating the code.
