* | New mark table implementationLars Knoll2017-03-091-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Automatically generate a table containing the data where JS Values and pointers are in objects in the JS heap. This will allow making the GC mark phase a lot more efficient. A bit of a special hack is currently required for MemberData and ArrayData, as they have a variable length, and we need to read the size from the object. We keep backwards compatibility with the old markObjects() functions for now (calling them if they are defined). Some further work on QV4::String and in a few other places is required before we can get remove the compatibility.

* V4: Pass scope around as parameters inside the runtime.Erik Verbruggen2016-06-221-2/+2
| | | | | | | | | | | | | | | | The implementation of many (or all) runtime functions consist of first creating a QV4::Scope, which saves and restores the JS stack pointer. It also prevents tail-calls because of that restoring behavior. In many cases it suffices to do that at the entry-point of the runtime. The return value of a JS function call is now also stored in the scope. Previously, all return values were stored in a ScopedValue, got loaded on return, and immediately stored in another ScopedValue in the caller. This resulted in a lot of stores, where now there is only one store needed, and no extra ScopedValue for every function.

* Remove type punning from QV4::Value.Erik Verbruggen2015-07-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The union in QV4::Value is used to do type punning. In C++, this is compiler-defined behavior. For example, Clang and GCC will try to detect it and try to do the proper thing. However, it can play havoc with Alias Analysis, and it is not guaranteed that some Undefined Behavior (or Compiler depenedent behavior) might occur. The really problematic part is the struct inside the union: depending on the calling convention and the register size, it results in some exciting code. For example, the AMD64 ABI specifies that a struct of two values of INTEGER class can be passed in separate registers when doing a function call. Now, if the AA in the compiler looses track of the fact that the tag overlaps with the double, you might get: ecx := someTag ... conditional jumps double_case: rdx := xorredDoubleValue callq someWhere If the someWhere function checks for the tag first, mayhem ensues: the double value in rdx does not overwrite the tag that is passed in ecx. Changing the code to do reinterpret_cast<>s might also give problems on 32bit architectures, because there is a double, whose size is not the same as the size of the tag, which could confuse AA. So, to fix this, the following is changed: - only have a quint64 field in the QV4::Value, which has the added benefit that it's very clear for the compiler that it's a POD - as memcpy is the only approved way to ensure bit-by-bit "conversion" between types (esp. FP<->non-FP types), change all conversions to use memcpy. Use bitops (shift/and/or) for anything else. - only use accessor functions for non-quint64 values As any modern compiler has memcpy as an intrinsic, the call will be replaced with one or a few move instructions. The accessor functions also get inlined, the bitops get optimized, so in all cases the compiler can generate the most compact code possible. This patch obsoletes f558bc48585c69de36151248c969a484a969ebb4 (which had the exact aliassing problem of the double and the tag as described above).
