Ayke van Laethem f107a24b72 all: use LLVM library provided by the system 2018-09-30 15:10:04 +02:00
Ayke van Laethem 5c79a93c85 tools/gen-device-svd: generate code for cluster arrays
This should make it possible to add support for PWM on nrf devices.

Ayke van Laethem 9b4a6dcc14 tools/gen-device-svd: move peripheral list to beginning
It's much easier to scan the source when the peripheral list is at the
front. Go doesn't care about the order of declaration anyway.

Ayke van Laethem e77a5af5d2 tools/gen-device-svd: rewrite with ElementTree
xml.etree.ElementTree is much easier to work with. This also fixes a few
small bugs in the parser. And as an added bonus, device generation got a
lot faster: apprently etree is a lot faster than minidom.

Ayke van Laethem 802350f8da main: helpful error message for flash cmd without -target 2018-09-29 22:39:44 +02:00
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.

Ayke van Laethem 5bf058a0a6 nrf: fix off-by-one in modulo of runtime.ticks
This code:
    foo & 0xffffff
Is equivalent to this code:
    foo % 0x1000000
However, to drop the high 8 bits, this calculation was used:
    foo % 0xffffff
This is far more expensive (and incorrect), as it needs an actual modulo
operation which increases code size and probably reduces speed on a
Cortex-M4 and needs library functions for a Cortex-M0 increasing code
size by a much bigger amount.

Ayke van Laethem 318567f398 ir: fix nil pointer dereference in IsVolatile 2018-09-29 00:11:05 +02:00
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).

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
}

Ayke van Laethem d8f0ddf3fa main: add tests
Add testing infrastructure and one initial test (for
src/runtime/print.go). More tests to be added later.

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?

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.

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.

Ayke van Laethem ddd4a39cb8 avr: fix default handler in interrupt vector
Apparently the target of a weak symbol must be defined in the same file
as where it is used as a weak symbol.

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.

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
