* Reduce number of allocations in AutoStopwatchDavid Teller2019-01-29-5/+20
| | | | | | | | | | | | | | | This patch fixes two related issues. 1. The AutoStopwatch uses a stack-allocated `mozilla::Vector` to communicate with its callback during each compartment switch. This vector was designed to allow its contents to be stack-allocated but they turned out to be accidentally heap-allocated. 2. During each tick, the stopwatch fills a vector `recentGroups_`. This vector always started with minimal capacity and had to grow repeatedly as groups were added, causing repeated reallocations. This patch preallocates `recentGroups_` to have the same capacity as the previous tick. We expect that this should eventually reach a stable size that closely matches the actual needs of the process.

* Rename TypeSet::clone to TypeSet::cloneIntoUninitialized to indicate that it ↵trav902018-09-19-9/+11
| | | | | | freshly initializes the TemporaryTypeSet* provided to it. Also removes existing code that, quite unnecessarily, partly initialized that argument.
* Don't use PodCopy/PodMove to implement typed-array element-to-element copyingtrav902018-09-19-4/+17
| | | | Standard std::copy and std::copy_n are readily optimized to the same thing, and they don't have a non-obvious requirement that the type being copied be trivial.
* Give uint8_clamped a defaulted (and also trivial) default constructor, copy ↵trav902018-09-19-6/+3
| | | | | | constructor, and copy-assignment operator. This also allows uint8_clamped to be permissibly memmove'd and memcpy'd.

* Convert the trailing array of BindingNames at the end of the various kinds ↵trav902018-09-02-13/+46
| | | | of scope data into raw unsigned chars into which those BindingNames are placement-new'd, rather than memcpy-ing non-trivial classes around and failing to comply with the C++ object model
* Simplify HeapSlot to make it trivially copyabletrav902018-08-12-6/+4
| | | | This removes the constructors, which were never called since we allocate arrays of HeapSlot with pod_malloc. The destructor is only ever called explicitly since we free this memory with js_free so it has been renamed to destroy(). Also removed is an unused manual barrier.
