The generated wasm is 575 bytes when compiled with -no-debug (and
works), which is a much better first experience for new users than
the 20KB+ added (atm) just from including fmt.
Adds another example showing the simple case
of executing main, adds a README explaining how
everything fits together and how to execute the compiled
code in the browser. Include a minimal webserver for
local testing.
* machine/uart: add core support for multiple UARTs by allowing for multiple RingBuffers
* machine/uart: complete core support for multiple UARTs
* machine/uart: no need to store pointer to UART, better to treat like I2C and SPI
* machine/uart: increase ring buffer size to 128 bytes
* machine/uart: improve godocs comments and use comma-ok idiom for buffer Put/Get methods
time.Sleep now compiles on all systems, so lets use that.
Additionally, do a few improvements in time unit handling for the
scheduler. This should lead to somewhat longer sleep durations without
wrapping (on some platforms).
Some examples got smaller, some got bigger. In particular, code using
the scheduler got bigger and the blinky1 example got smaller (especially
on Arduino: 380 -> 314 bytes).
This massively increases .data size, possibly because loads of unused
globals are included. I'll need to investigate what's going on here. For
now, increase the RAM size for nrf chips (the nrf52 has 64kB of RAM).
Missing features:
* keys other than strings
* more than 8 values in the hashmap
* growing a map when needed
* initial size hint
* delete(m, key)
* iterators (for range)
* initializing global maps
* ...more?
This is a big combined change. Other changes in this commit:
* Analyze makeinterface and make sure type switches don't include
unnecessary cases.
* Do not include CGo wrapper functions in the analyzer callgraph.
This also avoids some unnecessary type IDs.
* Give all Go named structs a name in LLVM.
* Use such a named struct for compiler-generated task data.
* Use the type and function names defined by the ssa and types
package instead of generating our own.
* Some improvements to function pointers.
* A few other minor improvements.
The one thing lacking here is interface-to-interface assertions.
