Ayke van Laethem	25cd982263	main: optionally build with LLD When building statically against LLVM, LLD is also included now. When included, the built in wasm-ld will automatically be used instead of the external command. There is also support for linking ELF files but because lld does not fully support armv6m this is not yet enabled (it produces a warning).	6 years ago
Ayke van Laethem	9bbb233cf0	main: include prebuilt compiler-rt libraries in release tarball This avoids depending on clang-7 to build compiler-rt for the most common ARM microcontrollers.	6 years ago
Ayke van Laethem	5b507593d2	main: give more context when running an external results in an error	6 years ago
Ayke van Laethem	914d383a96	all: update import paths to github.com/tinygo-org/tinygo	6 years ago
Ayke van Laethem	95e18f36d0	main: compile and run a program directly Do not try to use the ExectutionEngine of Go, instead compile the program in the conventional way and run the binary. This fixes some code duplication that causes slight (but problematic) misbehavior between `tinygo build` and `tinygo run`.	6 years ago
Ayke	107fccb288	all: add support for more architectures and GOOS/GOARCH (#118 ) This commit does two things: * It adds support for the GOOS and GOARCH environment variables. They fall back to runtime.GO* only when not available. * It adds support for 3 new architectures: 386, arm, and arm64. For now, this is Linux-only.	6 years ago
Ayke	873c1c3b4d	Reduce code size for AVR (#116 ) * all: add support for specifying target CPU in target config * avr: specify the chip name in the target CPU This reduces code size by a large margin. For examples/blinky, it reduces code size from 1360 to 1266 when compiling for the Arduino Uno (94 bytes, or ~7%).	6 years ago
Konstantin Yegupov	a8dd82538e	all: add flag to enable i64 parameters in WebAssembly	6 years ago
Ron Evans	cb648d8ae1	compiler: pass -cflags and -ldflags to tinygo CLI command Signed-off-by: Ron Evans <ron@hybridgroup.com>	6 years ago
Ayke van Laethem	6cacafb8dc	cgo: add package directory to header include paths	6 years ago
Ayke van Laethem	dea660b21c	main: compile C source files in packages TODO: C++ etc. files	6 years ago
Ayke van Laethem	e10d05c74f	loader: switch to custom program loader	6 years ago
Ayke van Laethem	da0a02d128	compiler: return error messages with source location Replace most errors returned by the compiler (using errors.New) with an error type that includes the source location.	6 years ago
Ayke van Laethem	b4c90f3677	compiler: lower interfaces in a separate pass This commit changes many things: * Most interface-related operations are moved into an optimization pass for more modularity. IR construction creates pseudo-calls which are lowered in this pass. * Type codes are assigned in this interface lowering pass, after DCE. * Type codes are sorted by usage: types more often used in type asserts are assigned lower numbers to ease jump table construction during machine code generation. * Interface assertions are optimized: they are replaced by constant false, comparison against a constant, or a typeswitch with only concrete types in the general case. * Interface calls are replaced with unreachable, direct calls, or a concrete type switch with direct calls depending on the number of implementing types. This hopefully makes some interface patterns zero-cost. These changes lead to a ~0.5K reduction in code size on Cortex-M for testdata/interface.go. It appears that a major cause for this is the replacement of function pointers with direct calls, which are far more susceptible to optimization. Also, not having a fixed global array of function pointers greatly helps dead code elimination. This change also makes future optimizations easier, like optimizations on interface value comparisons.	6 years ago
Ayke van Laethem	e817bd38ec	main: configure default GC in target JSON file	6 years ago
Ayke van Laethem	62d74d8329	all: compile and link using clang, where possible	6 years ago
Ayke van Laethem	f02766265c	targets: make compiler runtime selection more configurable	6 years ago
Ayke van Laethem	8402e84b6d	runtime: implement a simple mark/sweep garbage collector	6 years ago
Ayke van Laethem	ef93001ab8	runtime: add "none" garbage collector This collector does not implement runtime.alloc, so it is a quick-and-dirty way to check where in a program memory is allocated.	6 years ago
Ayke van Laethem	c220c140ef	all: make garbage collector configurable	6 years ago
Ayke van Laethem	ecb4742316	main: do not run legacy init interpreter with run subcommand Do not run the new init interpreter either. Just run the code.	6 years ago
Ayke van Laethem	21db7e6099	main: move "tinygo" build tag to compiler Replace "tgo" with "tinygo" and set it always (even with `tinygo run`).	6 years ago
Ayke van Laethem	c3c4a33b42	main: enable -initinterp by default It can still be disabled using -initinterp=false.	6 years ago
Ayke van Laethem	101d41dc58	compiler: pass i64 return value in an extra pointer param To support the WebAssembly<->JS barrier, return values also have to be passed in memory. i64 return values are used by syscall/js, so must be supported across this ABI barrier.	6 years ago
Ayke van Laethem	3d0ccb81c6	main: fix -initinterp flag It got accidentally replaced by -interp just before finalizing the previous commit.	6 years ago
Ayke van Laethem	bb3d05169d	interp: add new compile-time package initialization interpreter This interpreter currently complements the Go SSA level interpreter. It may stay complementary or may be the only interpreter in the future. This interpreter is experimental and not yet finished (there are known bugs!) so it is disabled by default. It can be enabled by passing the -initinterp flag. The goal is to be able to run all initializations at compile time except for the ones having side effects. This mostly works except perhaps for a few edge cases. In the future, this interpeter may be used to actually run regular Go code, perhaps in a shell.	6 years ago
Ayke van Laethem	3823870d07	main: print IR even when verification failed	6 years ago
Ayke van Laethem	60eefe1568	compiler: do not abort on verification failure	6 years ago
Ayke van Laethem	2e22d53e5d	compiler: work around i64 limitation in JavaScript JavaScript does not support i64 directly, so make sure we pass a pointer instead which can be read from JavaScript. This is a temporary workaround which should be removed once JavaScript supports some form of i64 (probably in the form of BigInt).	6 years ago
Ayke van Laethem	4e4f91bea7	main: cleanup printing of IR Panics don't usually happen nowadays, instead the compiler package returns errors while compiling. If it still panics, this is usually from within LLVM from where deferred functions are not run.	6 years ago
Marc-Antoine Ruel	a3d87456cd	tinygo: add 'tinygo' build tag This enables project to conditionally skip code that can't compile on tinygo.	6 years ago
Ayke van Laethem	c84fc6a670	main: gofmt	6 years ago
Ayke van Laethem	97d4558d81	main: update help text with new subcommands	6 years ago
Ayke van Laethem	980dceb192	main: refactor build option passing The list of options passed to build/run/gdb/etc commands was getting unwieldly and hard to add extra options to. Put all common build options in a single build config struct so that these options are more centralized.	6 years ago
Ayke van Laethem	e5e09747f0	all: add WebAssembly backend	6 years ago
Ayke van Laethem	9406a4d74a	main: add -opt= flag for the optimization level	6 years ago
Ayke van Laethem	a63af97e86	all: add emulation support for Cortex-M3 with QEMU	6 years ago
Ayke van Laethem	e50c6f1af1	main: generate binary files when compiling to .bin	6 years ago
Ayke van Laethem	22da104530	all: use compiler-rt for builtins	6 years ago
Ayke van Laethem	9d408b7cbc	main: hide OCD output by default in gdb subcommand In most cases, it's useless. But in some cases it may be critical if the OCD server (like openocd) has a problem. It would be nice if openocd would differentiate between stdout and stderr, and only write errors to stderr. But sadly it doesn't.	6 years ago
Ayke van Laethem	b08c8a0cf0	all: implement gdb sub-command for easy debugging	6 years ago
Ayke van Laethem	f107a24b72	all: use LLVM library provided by the system	6 years ago
Ayke van Laethem	802350f8da	main: helpful error message for flash cmd without -target	6 years ago
Ayke van Laethem	b6db84e916	main: use GOPATH from the environment Be more compatible with the Go toolchain by setting GOPATH in the same way. This makes it possible to flash and run examples from the standard GOPATH instead of only from the source tree.	6 years ago
Ayke van Laethem	0e813c4cb7	main: add -no-debug flag to avoid DWARF debug info	6 years ago
Ayke van Laethem	ed227b8fd3	all: fix errors reported by go vet	6 years ago
Ayke van Laethem	a2eaaa42a0	main: optimize 'tinygo run' Apparently -Oz without inliner is the fastest, probably because it removes code that would otherwise need to be emitted. TODO: does this mean that the ExecutionEngine compiles the module before running it? Can we control this?	6 years ago
Ayke van Laethem	6191d4e1ac	compiler: rename .Parse() to .Compiler() The fact it was called Parse() is more of a historical accident, as the compiler started out using the Go AST directly instead of Go SSA.	6 years ago
Ayke van Laethem	8a468786df	compiler: use config struct for options	6 years ago
Ayke van Laethem	fd6dda5e4f	main: run the compiler from any path	6 years ago
