* Include the ARMv7 assembler in the qmldevtools bootstrap buildSimon Hausmann2017-02-018-23/+281
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Bootstrap build fixSimon Hausmann2017-01-311-2/+5
| | | | | | | | Avoid the cache flushing code, it's of no use and won't compile due to the use of inline assembly. Change-Id: I1542b48f53f9210943bcf1f7cc5cc03f4abca695 Reviewed-by: Lars Knoll <lars.knoll@qt.io>
* Remove branch compaction #ifdefSimon Hausmann2017-01-319-64/+155
| | | | | | | | | | | | | Since the #ifdef for ARMv7 and ARM64 makes it impossible to cross compile, we need to replace it with a template specialization of LinkBuffer. The "old" LinkBuffer becomes LinkBufferBase, then there's a generic LinkBuffer that's a sub-class of LinkBufferBase. Then there's a BranchCompactingLinkBuffer template that implements the compaction and two ARMv7 and ARM64 specializations of LinkBuffer<T> end up being sub-classes of BranchCompactingLinkBuffer instead of LinkBufferBase.
