This allows the following packages to pass tests:
* crypto/des
* encoding/hex
I have not included crypto/rc4 as it doesn't pass tests on Go 1.11 (but
it works on later versions).
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.
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
These packages are known to pass tests with `tinygo test`. It's still a
very short list, but hopefully this list can be expanded to eventually
cover most or all of the standard library.
Right now this requires setting the -port parameter, but other than that
it totally works (if esptool.py is installed). It works by converting
the ELF file to the custom ESP32 image format and flashing that using
esptool.py.
This is only very minimal support. More support (such as tinygo flash,
or peripheral access) should be added in later commits, to keep this one
focused.
Importantly, this commit changes the LLVM repo from llvm/llvm-project to
tinygo-org/llvm-project. This provides a little bit of versioning in
case something changes in the Espressif fork. If we want to upgrade to
LLVM 11 it's easy to switch back to llvm/llvm-project until Espressif
has updated their fork.
This option was broken for a long time, in part because we didn't test
for it. This commit fixes that and adds a test to make sure it won't
break again unnoticed.
This is needed to make it available to more packages, for caching
purposes.
For caching, the version itself may not be enough during development.
But for regular releases, the version provides some protection against
accidentally using a cache entry that is invalid in a newer version.
This makes it possible to use Bluetooth on the BBC micro:bit.
Note that you need to use -programmer=cmsis-dap otherwise the SoftDevice
will be erased while flashing something that uses Bluetooth.
This commit changes pin numbering for atmega328 based boards (Uno, Nano)
to use the standard format, where pin number is determined by the
pin/port. Previously, pin numbers were based on what the Uno uses, which
does not seem to have a clear pattern.
One difference is that counting starts at port B, as there is no port A.
So PB0 is 0, PB1 is 1… PC0 is 8.
This commit also moves PWM code to the atmega328 file, as it may not be
generic to all ATmega chips.
Unfortunately, `tinygo flash` doesn't work here. You have to merge the
SoftDevice and the application hex with a mergehex tool and flash that
to the board.
This commit also adds a bit of version independence, in particular for
external commands. It also adds the LLVM version to the `tinygo version`
command, which might help while debugging.
This is necessary for better CGo support on bare metal. Existing
libraries expect to be able to include parts of libc and expect to be
able to link to those symbols.
Because with this all targets have a working libc, it is now possible to
add tests to check that a libc in fact works basically.
Not all parts of picolibc are included, such as the math or stdio parts.
These should be added later, when needed.
This commit also avoids the need for the custom memcpy/memset/memcmp
symbols that are sometimes emitted by LLVM. The C library will take care
of that.
This adds support for the `-scheduler=tasks` flag for AVR. On most AVR
chips you wouldn't want to run a real scheduler but it may be useful in
some cases, especially on devices with more RAM. It is disabled by
default.
This allows setting a different directory for experimental changes. For
example, I also have a llvm-project.master directory that tracks the
master branch. It is very useful to be able to temporarily use that
directory:
make llvm-build.master LLVM_BUILDDIR=llvm-build.master LLVM_PROJECT=llvm-project.master
Not tested on actual hardware, only on simavr. The main motivation for
adding this chip is to be able to run simulated tests using a much
larger memory space (16kB RAM, 128kB flash) without jumping to the XMega
devices that may not be as well supported by LLVM.
This makes the `make wasi-libc` command much more reliable and makes the
CI configuration simpler. Also, it avoids warnings when they are not
relevant.
