* Skip perfMapFile test on AndroidJan Arve Sæther2019-08-131-1/+1

* Transform V4_ENABLE_JIT into a featureUlf Hermann2019-04-251-9/+3
| | | | | | | | | | | | | | | | This way you can enable or disable the JIT when configuring Qt. The conditions for the availability of the JIT have also been cleaned up. There is no reason anymore to artificially restrict availability on x86 and x86_64. The reason for the existence of those clauses are old problems on windows that have been fixed by now. However, on arm and arm64, we need a specialization of the cacheFlush() function for each OS to be supported. Therefore, restrict to the systems for which such a specialization exists. iOS and tvOS are technically supported and you can enable the JIT via the feature flag now. Due to Apple's policy we disable it by default, though. Change-Id: I5fe2a2bf6799b2d11b7ae7c7a85962bcbf44f919 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>

* | V4: Generate function tables on 64bit windowsUlf Hermann2018-12-033-1/+111
|/ | | | | | | | | | | | | | In order for global exception handlers to be called reliably, the runtime needs to unwind through JIT-generated code. This can be facilitated by installing a "function table" for each JITed function that specifies "use the frame pointer". Also make sure to generate a function table for JIT'ed regular expressions. Those were forgotten also in the linux case. Fixes: QTBUG-50061 Change-Id: Ib0b8ae9356ed80afe1cab017e36efa4ccbe73f90 Reviewed-by: Simon Hausmann <simon.hausmann@qt.io>
* Use a separate process for testing perf.map fileUlf Hermann2018-03-272-0/+98
The environment change was too fragile. If the JIT ran before the relevant test function was executed, it would set the doProfile flag to false, and never re-evaluate the environment variable. The qmljs binary is only available for private tests, and the test didn't quite fit into qjsengine anyway. Therefore a new test for the QV4Assembler class that genertes the map files is added.
