Instead of putting tinygo_scanCurrentStack in scheduler_*.S files, put
them in dedicated files. The function tinygo_scanCurrentStack has
nothing to do with scheduling and so doesn't belong there. Additionally,
while scheduling code is made specific for the Cortex-M, the
tinygo_scanCurrentStack is generic to all ARM targets so this move
removes some duplication there.
Specifically:
* tinygo_scanCurrentStack is moved out of scheduler_cortexm.S as it
isn't really part of the scheduler. It is now gc_arm.S.
* Same for the AVR target.
* Same for the RISCV target.
* scheduler_gba.S is removed, using gc_arm.S instead as it only
contains tinygo_scanCurrentStack.
This commit allows debugging like the following:
GOARCH=arm tinygo gdb ./testdata/alias.go
This can be very useful to debug issues on a different instruction set
architecture but still on a host system.
I tested the following 7 configurations to make sure it works and I
didn't break anything:
GOOS=amd64
GOOS=386
GOOS=arm
GOOS=arm64
tinygo gdb -target=hifive1-qemu
tinygo gdb -target=cortex-m-qemu
tinygo gdb -target=microbit
To avoid breaking this, make sure we actually test x86-32 (aka i386 aka
GOARCH=386) support in CI.
Also remove the now-unnecessary binutils-arm-none-eabi package to speed
up CI a bit.
This fixes issue https://github.com/tinygo-org/tinygo/issues/1418. In
short, it appears there was a race condition that was only visible on
GOARCH=386 but not on GOARCH=amd64. Updating to a more recent chromedp
version fixes the issue.
* initial commit for WASI support
* merge "time" package with wasi build tag
* override syscall package with wasi build tag
* create runtime_wasm_{js,wasi}.go files
* create syscall_wasi.go file
* create time/zoneinfo_wasi.go file as the replacement of zoneinfo_js.go
* add targets/wasi.json target
* set visbility hidden for runtime extern variables
Accodring to the WASI docs (https://github.com/WebAssembly/WASI/blob/master/design/application-abi.md#current-unstable-abi),
none of exports of WASI executable(Command) should no be accessed.
v0.19.0 of bytecodealliance/wasmetime, which is often refered to as the reference implementation of WASI,
does not accept any exports except functions and the only limited variables like "table", "memory".
* merge syscall_{baremetal,wasi}.go
* fix js target build
* mv wasi functions to syscall/wasi && implement sleepTicks
* WASI: set visibility hidden for globals variables
* mv back syscall/wasi/* to runtime package
* WASI: add test
* unexport wasi types
* WASI test: fix wasmtime path
* stop changing visibility of runtime.alloc
* use GOOS=linux, GOARCH=arm for wasi target

For example, for running tests with -target=wasm or
-target=cortex-m-qemu. It looks at the output to determine whether tests
were successful in the absence of a status code.
The algorithm now checks for invalid UTF-8 sequences, which is required
by the Go spec.
This gets the tests of the unicode/utf8 package to pass.
Also add bytes.Equal for Go 1.11, which again is necessary for the
unicode/utf8 package.
On 64-bit Fedora, `lib64` is where the clang headers are, not `lib`. For
multiarch systems, both will exist, but it's likely you want 64-bit, so
check that first.
When using a SoftDevice, the MSD flash method is not appropriate as it
will erase the entire flash area before writing the new firmware. This
also wipes the SoftDevice. Instead, use OpenOCD to only rewrite the
parts of flash that need to be rewritten and leave the SoftDevice alone.
Only some pins (notably including GPIO2 aka machine.LED) have GPIO for
the default function 1. Other pins (such as GPIO 15) had a different
function by default. Function 3 means GPIO for all the pins, so always
use that when configuring a pin to use as a GPIO pin.
In the future, the mux configuration will need to be updated for other
functions such as SPI, I2C, etc.
By modifying the linker script a bit and adding the NRO0 header directly
in the assembly, it's possible to craft an ELF file that can be
converted straight to a binary (using objcopy or similar) that is a NRO
file. This avoids custom code for NRO files or an extra build step.
With another change, .nro files are recognized by TinyGo so that this
will create a ready-to-run NRO file:
tinygo build -o test.nro -target=nintendoswitch examples/serial
This ensures that stdout (println etc) keeps working in interrupts.
Generally you shouldn't print anything in an interrupt. However,
printing things for debugging is very useful and printing panic messages
can be critical when the code doesn't work for some reason.
This patch adds the `tinygo targets` command, which lists usable
targets (targets that can be used in the `-target` flag).
The assumption here is that usable targets can either be flashed or
emulated by TinyGo. There is one exception where it doesn't work yet:
the nintendoswitch target. Right now it requires some manual steps to
build a .nro file which can then be run by yuzu, hence why it doesn't
show up in the list.
Instead of specifying the emulator command in atmega328p.json, specify
it in the two boards based on it (arduino and arduino-nano). This makes
the configuration consistent with the machine package, which only
defines the CPUFrequency function in the board files (and not in
machine_atmega328p.json).
This is necessary for an upcoming VS Code extension to support TinyGo,
and may be useful for other people wanting to use proper autocompletion
etc in their IDE.
