Ayke van Laethem	e9b0a7d2ae	compiler: improve command line errors	6 years ago
Ayke van Laethem	0779ee6088	compiler: improve command line argument parsing To get more compatibility with the go command, implement a similar command line interface (with "tinygo build <package>" etc.). Other than that, an all-round cleanup of command parsing.	6 years ago
Ayke van Laethem	81b9edbe65	compiler: print() doesn't print spaces between arguments	6 years ago
Ayke van Laethem	8675025fc8	compiler: implement type assert without comma-ok	6 years ago
Ayke van Laethem	31e0662856	runtime: use a specialized runtime panic function This specifically fixes unix alloc(): previously when allocation fails it would (recursively) call alloc() again to create an interface due to lacking escape analysis. Also, all other cases shouldn't try to allocate just because something bad happens at runtime. TODO: implement escape analysis.	6 years ago
Ayke van Laethem	4ad6df3227	all: complete the implementation of interface asserts Because a few things were left unimplemented it only happened to kind-of work before in my test cases. This commit should complete interface-to-interface type asserts.	6 years ago
Ayke van Laethem	61e6f7cf5b	compiler: add debug information for function parameters Add 'optimized-out' parameters to functions. This might make debugging slightly easier by showing parameter names. Sadly I din't get setting variables to work. It might be a bug in CreateExpression.	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	30ac6ec281	compiler: don't try to get pointer methods I don't know why this was ever needed, but it seems to be incorrect and unnecessary.	6 years ago
Ayke van Laethem	0f83c3b3c6	compiler: allow copying a string to a slice Now that strings and slices are similar, this just works.	6 years ago
Ayke van Laethem	41a50ec336	compiler: simplify code for builtin len() Strings and slices now have the len element at the same location.	6 years ago
Ayke van Laethem	31f494e611	all: swap string from {len, ptr} to {ptr, len} for slice compatibility Having slices and strings be similar makes other code simpler.	6 years ago
Ayke van Laethem	5aa8b71ae1	compiler: implement builtin copy(dst, src []T) Not implemented: copying a string into a []byte slice.	6 years ago
Ayke van Laethem	fd9fa038a9	compiler: fix make([]T, ...) type	6 years ago
Ayke van Laethem	01635b5efd	runtime: move panic functions to a separate file	6 years ago
Ayke van Laethem	65358ed3c9	interpreter: don't panic on a nil (*ssa.Call).Object()	6 years ago
Ayke van Laethem	094c5561b6	compiler: implement make([]T, ...)	6 years ago
Ayke van Laethem	ef2c406127	compiler: implement comparing a pointer against nil	6 years ago
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
