Ayke van Laethem	a5ed993f8d	all: add compiler support for interrupts This commit lets the compiler know about interrupts and allows optimizations to be performed based on that: interrupts are eliminated when they appear to be unused in a program. This is done with a new pseudo-call (runtime/interrupt.New) that is treated specially by the compiler.	5 years ago
Jaden Weiss	7732c6f449	fix bug in IR regarding type aliases	5 years ago
Phil Kedy	55144ad608	WASM: Support for setting an imported function's module name (#455 ) * wasm: add support for setting a function's Wasm import module name by using the //go:wasm-module comment.	5 years ago
Ayke van Laethem	7ed6b45149	compiler: add the //go:noinline pragma This is directly useful to avoid some unsafety around runtime.alloc and should be useful in general. This pragma has the same form as in the main Go compiler: https://github.com/golang/go/issues/12312	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.	5 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	5cf7fba1a4	compiler: remove //go:volatile support	6 years ago

Justin Clift	064d001550	Trivial typo fixes	6 years ago
Ayke van Laethem	856e5fa179	ir: remove old cgo related code There is now a custom implementation of CGo based on libclang.	6 years ago
Ayke van Laethem	92d9b780b5	all: remove init interpretation during IR construction The interp package does a much better job at interpretation, and is implemented as a pass on the IR which makes it much easier to compose. Also, the implementation works much better as it is based on LLVM IR instead of Go SSA.	6 years ago
Ayke van Laethem	95d895646a	loader/cgo: add support for function pointers	6 years ago
Ayke	01f6aff422	loader: support global variables in CGo (#173 ) Global variables (like functions) must be declared in the import "C" preamble and can then be used from Go.	6 years ago
Ayke van Laethem	914d383a96	all: update import paths to github.com/tinygo-org/tinygo	6 years ago
Ayke van Laethem	1db9a162da	all: go fmt The import path changes changed the order of imports, but no `go fmt` was run before the commit. Oops...	6 years ago
Ayke van Laethem	9092dbcc53	all: rename go-llvm to new import path the new import path is: tinygo.org/x/go-llvm	6 years ago
Ayke van Laethem	602c264749	all: rewrite goroutine lowering Before this commit, goroutine support was spread through the compiler. This commit changes this support, so that the compiler itself only generates simple intrinsics and leaves the real support to a compiler pass that runs as one of the TinyGo-specific optimization passes. The biggest change, that was done together with the rewrite, was support for goroutines in WebAssembly for JavaScript. The challenge in JavaScript is that in general no blocking operations are allowed, which means that programs that call time.Sleep() but do not start goroutines also have to be scheduled by the scheduler.	6 years ago
Ayke van Laethem	ecf6ffa62e	all: add bare-bones Cgo support	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	564b1b3312	compiler: always use fat function pointers with context This reduces complexity in the compiler without affecting binary sizes too much. Cortex-M0: no changes Linux x64: no changes WebAssembly: some testcases (calls, coroutines, map) are slightly bigger	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	318567f398	ir: fix nil pointer dereference in IsVolatile	6 years ago
Ayke van Laethem	8d170d3bd2	all: change special type __volatile to pragma //go:volatile This is one step towards removing unnecessary special casts in most cases. It is also part of removing as much magic as possible from the compiler (the pragma is explicit, the special name is not).	6 years ago
Ayke van Laethem	13cb7d6503	avr: add interrupt support Interrupts are supported using a special //go:interrupt pragma. For example: //go:interrupt INT0_vect func handleINT0() { // do something here }	6 years ago

Ayke van Laethem	2ca2220e44	compiler: move SSA construction to ir.go	6 years ago
Ayke van Laethem	1f2af7d848	compiler: do not remove dead globals These were not removed when they contain data, and will be removed by LLVM anyway.	6 years ago
Ayke van Laethem	43b8c24226	compiler: implement interface assertions This is a lot harder than 'regular' type assertions as the actual methods need to be checked.	6 years ago
Ayke van Laethem	83ad0b6137	all: move bootstrapping IR to Go runtime This has the benefit of not requiring a 'runtime' IR file, so that complete relocatable files can be built without requiring input IR. This makes the compiler a lot easier to use without the Makefile. Code size is not affected.	6 years ago
Ayke van Laethem	bfff0c33e4	Fix external globals This broke the allocator on ARM, and with that the blinky example.	6 years ago
Ayke van Laethem	88b6b2e7f5	Optimize/eliminate bounds checking TODO: do better at it by tracking min/max values of integers. The following straightforward code doesn't have its bounds checks removed: for _, n := range slice { println(n) }	6 years ago

Ayke van Laethem	b13cfc5255	Be able to deal with anonymous functions	6 years ago
Ayke van Laethem	74bd378c29	Replace _llvm_* workaround in the scheduler with //go:linkname This also removes the need for the _llvm_ special case in the compiler. And it makes the scheduler code a whole lot nicer!	6 years ago

Ayke van Laethem	c25b448758	Rewrite init() interpretation to a real interpreter Instead of mostly heuristics, actually execute the init() instruction in an interpreter to calculate initializers for globals. This is far more flexible and extensible, and gives the option of extending the interpreter to other code and make it a partial evaluator.	6 years ago
Ayke van Laethem	7460e10894	Add dead code elimination (DCE) pass This should make it much easier (in the future) to use the standard library when unused functions contain unimplemented features. But more importantly, it makes later passes better and makes compiling faster by not having to scan dead code.	6 years ago

Ayke van Laethem	574c7ec047	Refactor: Use our own types as much as possible from the analysis Previously, mostly the types from the ssa package were used directly with the types from analysis.go as an overlay. This commit uses these types everywhere and renames a few things here and there to make things clearer.	6 years ago
