Ayke van Laethem	c66d979ba3	compiler: avoid some stack frames when this is unnecessary Some instructions do not create new values, they transform existing values in some way (bitcast, getelementptr, etc.). Do not store them in the stack object. This lowers the size of the repulsion demo from 100kB to 98kB (with a baseline of 72kB for the leaking GC). That's a useful reduction in file size.	5 years ago
Ron Evans	fc9188a298	machine/samd21/arduino-nano33: adds support for Arduino Nano33 IoT along with mapping to NINA-W102 WiFi chip. Also adds DTR and RTS functions along with timeouts to USBCDC functions to prevent lockups. Signed-off-by: Ron Evans <ron@hybridgroup.com>	5 years ago
Ayke van Laethem	ffa38b183b	all: add HiFive1 rev B board with RISC-V architecture This page has been a big help in adding support for this new chip: https://wiki.osdev.org/HiFive-1_Bare_Bones	6 years ago

Ayke van Laethem	6611578ec8	compiler: remove some TODOs These have long since been implemented.	5 years ago
Ayke van Laethem	d49a363d0d	compiler: track all pointers returned by runtime.alloc In particular, track the pointers to the memory allocated for coroutine frames. Before this change, the following code would show memory corruption: https://github.com/johanbrandhorst/wasm-experiments/blob/master/canvas/main.go	5 years ago
Ayke van Laethem	385d1d0a5d	compiler,runtime: implement a portable conservative GC	6 years ago
Ayke van Laethem	00e91ec569	all: rename garbage collectors dumb -> leaking: make it more clear what this "GC" does: leak everything. marksweep -> conservative: "marksweep" is too generic, use "conservative" to differentiate between future garbage collectors: precise marksweep / mark-compact / refcounting.	6 years ago
Daniel Esteban	1fd0c8d48c	adds PowerSupplyActive to enable supply voltages to nRF52840 and (#430 ) * machine/reelboard: adds PowerSupplyActive to enable supply voltages to nRF52840 and peripherals.	5 years ago
Daniel Esteban	d34bb7e708	add reelboard pins for the epaper display and the reset pin (#429 ) * machine/reelboard: added descriptive pin names for the epaper display and the reset pin	5 years ago
Ayke van Laethem	a328bbdff3	main: small refactor in error printing Use a type switch instead of an if/else chain. This results in much more readable code.	5 years ago
Ayke van Laethem	4ecd478d82	machine: add generic board support on non-baremetal hardware Instead of trying to modify periperhals directly, external functions are called. For example, __tinygo_gpio_set sets a GPIO pin to a specified value (high or low). It is expected that binaries made this way will be linked with some extra libraries that implement support for these functions. One particularly interesting case is this experimental board simulator: https://github.com/aykevl/tinygo-play Compiling code to WebAssembly with the correct build tag for a board will enable this board to be simulated in the browser. Atmel/Microchip based SAMD boards are not currently supported, because their I2C/SPI support is somewhat uncommon and harder to support in the machine API. They may require a modification to the machine API for proper support.	6 years ago
Justin Clift	40b193f1fa	circleci: update source and build cache keys	5 years ago
Justin Clift	7fd5ec8661	Makefile: use the LLVM monorepo The -DLLVM_TOOL_CLANG_TOOLS_EXTRA_BUILD=OFF option turning off the building of the extra clang tools is required, otherwise linking the tinygo binary fails.	5 years ago
m-chichikalov	84618c45eb	Added supporting suctom TargetSpec json file via -target flag.	5 years ago
Carolyn Van Slyck	c0ff4e566d	Include test in helptext	5 years ago
Carolyn Van Slyck	ce9b21a270	Default package name to . when not specified When running tinygo build, and the positional argument for the package is not specified, default it to "."	5 years ago
Ayke van Laethem	ed7c242a09	runtime: fix a heap corruption where some blocks were not marked as reachable This is a rather critical error and I wonder why it hasn't been discovered earlier.	5 years ago
Justin Clift	46872a70b1	Trivial typo fix	5 years ago

Carolyn Van Slyck	208e1719ad	Add test command to tinygo (#243 ) * Add test command to tinygo	5 years ago
Ayke van Laethem	a3d1f1a514	all: try more locations to find Clang built-in headers This commit fixes the case where TinyGo was built with `go build` and LLVM sources were never downloaded into the TinyGo source directory.	5 years ago
Tomer Elmalem	3e1c0d90c5	Add implementation for os.Exit and syscall.Exit	5 years ago
Ayke van Laethem	b7197bcaae	compiler,runtime: implement non-blocking selects Blocking selects are much more complicated, so let's do non-blocking ones first.	5 years ago
Ayke van Laethem	8890a0f3c8	compiler,runtime: store channel size in the channel itself This may have a small effect on code size sometimes, but will simplify the implementation of the select statement.	5 years ago
Justin Clift	5be412dabe	Makefile: using an alternative LLVM build dir now works	6 years ago
Ayke van Laethem	412ec5b789	Makefile: drop the -lclangToolingRefactor library It is not necessary and does not exist in LLVM 9.	5 years ago
Ayke van Laethem	b0e767c4a7	compiler: move global handling from ir to compiler package This is part of a larger rafactor that tries to shrink the ir package and in general tries to shrink the amount of state that is kept around in the compiler. The end goal is being able to compile packages independent of each other, linking them together in a later stage. Along the way, it cleans up lots of old cruft that has accumulated over the months. This refactor also results in globals being loaded lazily. This may be a problem for some specific programs but will probably change back in a commit in the near future.	6 years ago
Ayke van Laethem	6b5b4a681d	compiler: refactor named types to create them lazily This commit refactors named types to be created lazily. Instead of defining all types in advance, do it only when necessary.	6 years ago
Ayke van Laethem	88bb61f287	compiler: return a valid (undef) value from a unsupported select Returning a nil value may lead to problems later on. Just return undef here, so that further compilation will at least be safe (the result will be discarded anyway).	5 years ago
Ayke van Laethem	e169e3b996	compiler: remove superfluous 'err' result in decodeFuncValue	5 years ago
Ayke van Laethem	aa8957dd05	compiler: support non-constant syscall numbers Not all syscalls use constant numbers.	6 years ago
Ayke van Laethem	8e5731aee7	compiler: add support for pointers as map keys	6 years ago
Justin Clift	0cc35b6188	Add a note to use --recursive when cloning the TinyGo repo	5 years ago
Ayke van Laethem	5cf7fba1a4	compiler: remove //go:volatile support	6 years ago
Ayke van Laethem	e67506ee68	arm: update to avoid //go:volatile This change results in changes to all smoketests for Cortex-M based chips: they get a bit smaller (32-48 bytes). I'm not sure why but probably because the inliner made a different inlining decision. There was a similar effect when files generated from SVD files switched to the new volatile types so it's probably harmless.	6 years ago
Ayke van Laethem	f2c205a008	machine: update ringbuffer to use runtime/volatile.Register8 This avoids the //go:volatile pragma, which will be removed soon. There were no changes to the output of the smoke tests.	6 years ago
Ayke van Laethem	c84c625585	runtime: update to avoid //go:volatile There was exactly one change in the output of the smoke tests: examples/test. However, it still runs just fine on a PCA10040.	6 years ago
Ayke van Laethem	9673ad3774	all: move Register{8,16,32} values into runtime/volatile This avoids duplication of code. None of the smoke tests have changed their output.	6 years ago
Ayke van Laethem	66aca428ba	compiler: rename import path if it lies in TINYGOPATH This allows importing (for example) both "github.com/tinygo-org/tinygo/src/machine" and "machine" without issues. The former is renamed to just "machine".	6 years ago
Ayke van Laethem	ec87811420	compiler: do not panic on duplicate functions Instead, show a regular error message. This is much more user-friendly.	6 years ago
Ayke van Laethem	776dc1e0d9	main: show a better error when version detection of GOROOT failed	6 years ago
Ron Evans	beea2f1f30	docs: add note to current/future contributors to please start by opening a GH issue to avoid duplication of effort Signed-off-by: Ron Evans <ron@hybridgroup.com>	6 years ago
Ayke van Laethem	5f9c683abf	main: return an error when running a command failed	6 years ago
