Ayke van Laethem	0a40219680	compiler: implement comparing channel values	2019-05-14 11:18:38 +02:00
Ayke van Laethem	9a54ee4241	compiler: allow larger-than-int values to be sent across a channel ... Instead of storing the value to send/receive in the coroutine promise, store only a pointer in the promise. This simplifies the code a lot and allows larger value sizes to be sent across a channel. Unfortunately, this new system has a code size impact. For example, compiling testdata/channel.go for the BBC micro:bit, there is an increase in code size from 4776 bytes to 4856 bytes. However, the improved flexibility and simplicity of the code should be worth it. If this becomes an issue, we can always refactor the code at a later time.	2019-05-05 16:46:50 +02:00
Ayke van Laethem	ad7297a539	all: implement trivial select statements ... Implement two trivial uses of the select statement. Always blocking: select {} No-op: select { default: } Go 1.12 added a `select {}` instruction to syscall/js, so this is needed for Go 1.12 support. More complete support for select will be added in the future.	2019-03-23 16:16:19 +01:00
Ayke van Laethem	2e4dd09bbc	compiler: add support for channel operations ... Support for channels is not complete. The following pieces are missing: * Channels with values bigger than int. An int in TinyGo can always contain at least a pointer, so pointers are okay to send. * Buffered channels. * The select statement.	2019-01-21 22:09:37 +01:00
