Other chips support explicit control of pull-up vs pull-down for GPIO input. Support that with bluepill also. PinInputPullUpDown is maintained for back-compat. It is implicit pull-down.
This was broken because multiple packages in the program were named
'main', even one that was imported (by the generated main package).
This fixes tests for main packages.
Previously a command like the following would incorrectly print FAIL:
tinygo test -c math
This commit fixes this issue by defaulting to a passing test (the test
is marked as passed if it isn't run).
Because arm.SVCall1 lets pointers escape, the return value of
sd_softdevice_is_enabled (passed as a pointer in a parameter) will
escape and thus this value will be heap allocated.
Use a global variable for this purpose instead to avoid the heap
allocation. This is safe as waitForEvent may only be called outside of
interrupts.
Do not store the context parameter (which is used for closures and
function pointers) in the goroutine start parameter bundle for direct
functions that don't need a context parameter. This avoids storing the
(undef) context parameter and thus makes the IR to start a new goroutine
simpler in most cases.
This reduces code size in the channel.go and goroutines.go tests.
Surprisingly, all test cases (when compiled with -target=microbit) have
a changed binary, I haven't investigated why but I suppose the codegen
is slightly different for the runtime.run function (which starts the
main goroutine).
Closure variables are allocated in a parent function and are thus never
nil. Don't do a nil check before reading or modifying the value.
This commit results in a slight reduction in code size in some test
cases: calls.go, channel.go, goroutines.go, json.go, sort.go -
presumably wherever closures are used.
Not sure why you would ever do this, but it appears to be allowed by the
Go specification and previously TinyGo would crash with an unhelpful
error message when you would do this. I don't see any practical use of
it.
The implementation simply runs the builtin directly.
This commit adds a test for both WebAssembly and Cortex-M targets (which
use a different way of goroutine lowering) to show how they lower
goroutines. It makes it easier to show how the output changes in future
commits.
While LLVM coroutines are one implementation of goroutines, it is not
the only one. Therefore, rename the tests to 'goroutines' to better
describe what they're for.
Move the code from the compiler.go file to the goroutine.go file, which
is a more appropriate place. This keeps all the goroutine related code
in one file, to make it easier to find.
These variants uses an unsafe.Pointer instead of uintptr so that the
pointer/non-pointer fields match those of real slices and strings. This
may be necessary in the future once we switch to a precise garbage
collector.
