Ayke van Laethem	25e73a5439	compiler: align and zero-initialize stack allocated values	6 years ago
Ayke van Laethem	2917347ff5	compiler: implement operations on some named types	6 years ago
Ayke van Laethem	e1e3dbdce6	compiler: correctly generate global hashmaps of size > 8 Static map generation used the last bucket instead of the first bucket in the chain, which caused lots of missing entries in hashmaps with multiple buckets (size > 8).	6 years ago
Ayke van Laethem	ec73bd6a26	compiler: optimize runtime.stringToBytes calls This optimization makes sure the following pattern doesn't do a heap allocation (assuming Write doesn't modify the slice): var w *machine.UART = ... w.Write([]byte("foo")) As long as Write doesn't modify the slice and LLVM can detect this, a call to runtime.stringToBytes with the necessary allocation + copy is avoided.	6 years ago
Ayke van Laethem	4219652535	compiler: add basic heap-to-stack optimization	6 years ago
Ayke van Laethem	3289dd7134	compiler: use a fresh context for every compilation	6 years ago
Ayke van Laethem	e8f211935e	compiler: fix expanded structs in invoke calls	6 years ago
Ayke van Laethem	4957db89f4	compiler: fix interface calls for big underlying values When the underlying value of an interface does not fit in a pointer, a pointer to the value was correctly inserted in the heap. However, the receiving method still assumed it got the underlying value instead of a pointer to it leading to a crash. This commit inserts wrapper functions for method calls on interfaces. The bug wasn't obvious as on a 64-bit system, the underlying value was almost always put directly in the interface. However, it led to a crash on the AVR platform where pointer are (usually) just 16 bits making it far more likely that underlying values cannot be directly stored in an interface.	6 years ago
Ayke van Laethem	482c5633dd	compiler: put debug information on package initializer functions Make sure package initializers show up in backtraces, as they should. In practice, it doesn't actually break backtraces as these functions are usually inlined anyway, but it may help to debug an error in initialization code.	6 years ago
Ayke van Laethem	5db43e8d04	compiler: move Optimize() function to a separate file In the future, there will be more optimizations. Let's keep them in a separate file for separation of concerns.	6 years ago
Ayke van Laethem	5d2ffa79e5	compiler: improve debug info to cover initialization	6 years ago
Ayke van Laethem	f107a24b72	all: use LLVM library provided by the system	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	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	174b6333f8	compiler: fix expanding zero-length structs	6 years ago
Ayke van Laethem	ed227b8fd3	all: fix errors reported by go vet	6 years ago
Ayke van Laethem	c9ae72a105	all: allow -O0 optimization level	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	1b229a8f8b	compiler: support compiling individual .go files For example: tinygo run ./src/examples/test/test.go	6 years ago
Ayke van Laethem	a561e9a9ac	ir: move adding packages from the compiler	6 years ago
Ayke van Laethem	9df04a2170	compiler: fix panic on import errors I think this is a problem in the loader package - it doesn't seem to return errors for missing packages.	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
Ayke van Laethem	2938437efc	compiler: make string data unnamed addresses This ensures LLVM can merge identical strings, and thus reduces code size in some cases.	6 years ago
Ayke van Laethem	7cea40bcb5	compiler: small cleanup in call handling code	6 years ago
Ayke van Laethem	fdfa810060	compiler: expand small structs Use fields of small structs (3 or less fields when flattened recursively) directly as parameter values. Advantages: * Code size is slightly reduced, both on unix and nrf. * AVR can finally deal with struct parameters - at least the small ones. examples/test now compiles. A real fix for struct parameters should go into upstream LLVM, but this is a nice win. fixes #20	6 years ago
Ayke van Laethem	b2cbfa78ca	compiler: refactor compiler into separate package	6 years ago
