Ayke van Laethem	f44d2f718f	compiler: rewrite defer support to better support them This costs a bit in code size, but should be more flexible for the future to implement recover() and running deferred functions while panicking.	6 years ago
Ayke van Laethem	87dd1a1fe5	compiler: fix debug metadata Not setting the correct debug location at function entry leads to instructions getting the address of the previously emitted function, which is of course wrong. LLVM complains about it when validating a module.	6 years ago
Ayke van Laethem	9101ea11bf	examples: clean up examples and add blinky1 for Arduino Arduino has trouble supporting anything that's not extremely simple, so add a simple blinky example for it. Also, it may be useful anyway.	6 years ago
Ayke van Laethem	17b5b6ec5b	all: use less magic in memory-mapped IO Don't store addresses in the values of registers, this leads to problems with char arrays (among others). Instead, do it like it's done in C with raw addresses cast to struct pointers. This commit also splits gen-device.py, as AVR and ARM have very different ideas of what a register is. It's easier to just keep them separate.	6 years ago
Ayke van Laethem	93248c93ed	avr: remove device files, use them from a subrepository These files don't really belong in this repository. It's better to generate them automatically from a source, like the one provided by the avr-rust project. So a new command `make gen-device-avr` has been provided for this purpose.	6 years ago
Ayke van Laethem	7258553528	compiler: implement const pointers from integers These raw pointers are used for memory-mapped IO.	6 years ago
Ayke van Laethem	ce71d18450	runtime/nrf: remove AEABI functions Apparently these functions were not actually used.	6 years ago
Ayke van Laethem	92877f8371	Makefile: some cleanups Remove $(GCC) and $(LLC) which were not used anymore, and display binary size even when building for the host.	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	0746d61639	compiler: move optimizer into the binary	6 years ago
Ayke van Laethem	c109ec0955	compiler: let a failed typeassert return the nil value See the comment in the source for details. The underlying type would be casted to the final one even before the type is checked. This apparently led LLVM to think the type cast was OK, so it speculatively dereferenced a pointer (while the underlying type was an int). Speculatively dereferencing a pointer is fine when it is a valid pointer, but when it is not it leads to a segfault (or worse). This is what I saw, and it took me a while to figure out where it went wrong.	6 years ago
Ayke van Laethem	efdc2b8672	compiler: add basic debug info Only implements debugging with source lines and stacktraces (without parameters), which already is a huge improvement over no debug information at all. This should be extended to arguments and local variables (of the correct DWARF type), but this is more work.	6 years ago
Ayke van Laethem	a7fcef62e0	compiler: implement comparing interfaces to nil Comparing an interface to nil is easy, as the dynamic type is also nil. Comparing the dynamic values (when the dynamic types match) is much harder and depends on reflection capabilities, so is not yet implemented.	6 years ago
Ayke van Laethem	c100e4d67f	compiler: fix nil constant interface A nil interface has no dynamic type (or: nil dynamic type). Don't try to use the static type as the dynamic type, because these are different.	6 years ago
Ayke van Laethem	4ed04309a3	compiler: truncate shift amount when needed	6 years ago
Ayke van Laethem	ebd87ce4cd	compiler: implement []byte(str)	6 years ago
Ayke van Laethem	a080ce26ef	compiler: implement string slicing	6 years ago
Ayke van Laethem	1170cdc21f	compiler: implement Field expression This expression is used when calling a method on an embedded type in a struct.	6 years ago
Ayke van Laethem	9519f989bc	runtime/scheduler: make debugging easier + rename some functions This shouldn't affect functionality but makes debugging a whole lot easier. A scheduler is difficult so make it easy to debug.	6 years ago
Ayke van Laethem	8ba3fef7d7	runtime/scheduler: always update task state Not updating it only saves 4 bytes and makes debugging harder.	6 years ago
Ayke van Laethem	d183f12395	nrf: fix sleep For some reason, the old behavior stopped working at some point (maybe at the nrfx update?). Change sleep behavior to be more correct.	6 years ago
Ayke van Laethem	1e90858145	Fix blocking functions Don't think they're blocking when the scheduler has been disabled.	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	42cddd3260	Move runtime.TargetBits out of the compiler	6 years ago
Ayke van Laethem	9fca0e99b5	compiler: use InternalLinkage where appropriate Internal linkage means that symbols show up in tools like objdump, which is very useful for debugging.	6 years ago
Ayke van Laethem	58c87329d4	Implement closures and bound methods	6 years ago
Ayke van Laethem	58b853bbef	Defer for trivial cases	6 years ago
Ayke van Laethem	cd2a9d99a1	Add dummy runtime.SetFinalizer() Requirement for the os package. The os package can't be compiled yet, though.	6 years ago
Ayke van Laethem	887814a69d	Be able to handle complex64 and complex128 types No support for complex types yet, but at least be able to handle their types.	6 years ago
Ayke van Laethem	94ce893ab4	Copy printfloat() from original runtime I've tried writing my own, but I couldn't make it correct in all cases. So just copy the one from upstream for now, hopefully to be replaced at some point. TODO: add a printfloat32() implementation, now it just casts to float64. This will be useful for embedded systems that sometimes have float32 but not float64.	6 years ago
Ayke van Laethem	46d2d2e777	Add support for floats I'm not sure all operations are supported but the vast majority should be supported now. This commit also refactors binop translation.	6 years ago
Ayke van Laethem	3cdf606183	Improve runtime.printuint32: avoid recursion This reduces size slightly at least on the PCA10040, and is probably faster and probably uses less stack as well.	6 years ago
Ayke van Laethem	f057d612fc	Add support for indexing in an array by a non-constant	6 years ago
Ayke van Laethem	a1359d7f64	passes: small code cleanup	6 years ago
Ayke van Laethem	734b0cb6bc	Implement runtime functions for reflect The reflect package isn't supported yet. But at least the Go parser/typechecker can now deal with it.	6 years ago
Ayke van Laethem	b13cfc5255	Be able to deal with anonymous functions	6 years ago
Ayke van Laethem	674b506bb2	Replace compiler hack for sync package with //go:linkname	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	771f23e320	Implement //go:linkname pragma	6 years ago
Ayke van Laethem	906e061e37	Replace own dummy syscall with standard library syscall This makes it easier to support other standard library packages.	6 years ago
Ayke van Laethem	e01259ba77	interpreter: string concatenation Sometimes strings are concatenated in a way that isn't const-propagated by the SSA transformation (e.g. the result of a function call). Concatenate them during init() interpretation.	6 years ago
Ayke van Laethem	16cdffc367	Try to interpret simple function calls in init() functions This is useful for example for globals like these: import "errors" var MyError = errors.New("mymodule: something went wrong!")	6 years ago
Ayke van Laethem	15f62b29cf	Add runtime.GOOS	6 years ago
Ayke van Laethem	82d0d70ba2	Add (hardcoded) runtime.GOROOT() Necessary for the time package.	6 years ago
