* allocate only expressions in arenas - functions, imports, exports, function ↵Alon Zakai2016-04-272-7/+10
| | | | types, can more simply be held by unique_ptrs on the owning module. this avoids need to coordinate arena allocation for their elements, and only the far more plentiful expression nodes are a perf factor anyhow
* add an ArenaVector for internal array allocations in expression nodesAlon Zakai2016-04-263-3/+4
|
* ast_utils improvements (#399)Alon Zakai2016-04-261-6/+3
| | | | | | | | | * make EffectAnalyzer a little more fun to use * create a convert() method that can turn a node into a smaller node, reusing its memory, and use that in nop() * use convert in wasm-linker
* selectify if-elses with no control flow in themAlon Zakai2016-04-251-0/+30

* optimize returns that flow outAlon Zakai2016-04-251-3/+21
|
* optimize breaks with values in RemoveUnusedBrs, check if their value can ↵Alon Zakai2016-04-251-14/+32

* Function parallelism (#343)Alon Zakai2016-04-158-2/+18
| | | | * allow traversals to mark themselves as function-parallel, in which case we run them using a thread pool. also mark some thread-safety risks (interned strings, arena allocators) with assertions they modify only on the main thread
