2019-02-12Feature/alloc for ir inst creation review (#839)jsmall-nvidia
* Make MemoryArena rewindable. * Add test for rewinding MemoryArena * Use memory rewinding in IRInst lookup instead of malloc/free. * Small tidy. * Don't bother recreating instruction if after lookup it's found it's new. * Fix 32 bit signed compare issue. * Improve documentation around MemoryArena. * * Improve perf of test for hash expansion on Dictionary * First attempt at TryGetOrAdd * Improve comments around findOrEmitHoistableInst * Removed template<T> from Dictionary. Use TryGetValueOrAdd to findOrEmitHoistableInst * Use TryGetValueOrAdd in findOrEmitHoistableInst * Use Type thing = {} to initialize type over Type thing{} style.

2018-09-14Improvements around IR representation and memory usage (#635)jsmall-nvidia
* * Remove dispose from IRInst * Use MemoryArena instead of MemoryPool * Make all IRInst not require Dtor - by having ref counted array store ptrs that need freeing * Increase block size - typically compilation is 2Mb of IR space(!) * Fix issues around StringRepresentation::equal because null has special meaning. * Don't bother to construct as String to compare StringRepresentation, just used UnownedStringSlice. * Added fromLiteral support to UnownedStringSlice and use instead of strlen version. * Use more conventional way to test StringRepresentation against a String. * Fix gcc/clang template problem with cast.
2018-09-13Feature/memory arena improvements (#633)jsmall-nvidia
* First pass at MemoryArena. * First pass at RandomGenerator. * Extract TestContext into external source file. * Fix warning on printf. * Use enum classes for Test enums. OutputMode -> TestOutputMode. * First pass at FreeList unit test. * Auto registering tests. Improvements to RandomGenerator. * Remove the need for unitTest headers - cos can use registering. * Added unitTest for MemoryArena. * Do unit tests. * Fix typo. * Fix problem limiting errors from TestContext. * Refactor of MemoryArena * Removed the ability to rewind (to improve memory usage/simplify) * Better memory usage - around oversized blocks + Will keep allocating from a normal block if more than 1/3 memory left, or an oversided block is allocated * Better unitTest coverage for MemoryArena. * Fixes based on code review * Remove e prefix from enum class types for TestContext * Added extra checking for allocations sizes * Fixed some typos * Added std::is_pod test to allocateAndCopyArray * Add include for is_pod needed for linux build.
