This switches the Espressif fork from LLVM 19 to LLVM 20, so we can use
the improvements made between those LLVM versions. It also better aligns
with the system-LLVM build method, which currently also defaults to LLVM
20.
Note that this disables the machine outliner for RISC-V. It appears
there's a bug in there somewhere, with the machine outliner enabled the
crypto/elliptic package tests fail with -target=riscv-qemu.
This should ideally be investigated and reported upstream.
The revive command seems to have had a syntax error in the file
input glob. It appears to have been broken in a way that did not
result in a return code being set. This change uses 'find' to
build the input to the linter.
Note that it is expected to fail the CI script, because it is
uncovering some existing lint issues that were not being caught.
With these flags, the TinyGo binary gets 18.8MB (11.6%) smaller. That
seems like a quite useful win for such a small change!
This is only for Linux for now. MacOS and Windows can be tested later,
the flags for those probably need to be modified.
Originally inspired by:
https://discourse.llvm.org/t/state-of-the-art-for-reducing-executable-size-with-heavily-optimized-program/87952/18
There are some other flags like -Wl,--pack-dyn-relocs=relr that did not
shrink binary size in my testing, so I've left them out.
This also switches the linker to prefer mold or lld over the default
linker, since the system linker is usually ld.bfd which is very slow.
(Also, for some reason mold produces smaller binaries than lld).
Running tests against an installed TinyGoRoot fails with:
```
=== CONT TestBuild/WebAssembly/gc.go-boehm
main_test.go:441: wasi-libc: did not find any files for pattern builder.filePattern{glob:"dlmalloc/src/dlmalloc.c", exclude:[]string(nil)}
```
because these files are not there, and are required with Boehm GC.
* machine: add support for BTT SKR Pico
Adds support for the BigTreeTech SKR Pico 3D-printer mainboard.
This board uses the RP2040.
* Fix build tag
* Add I2C defaults
* Run UART test instead of blinky1
* Use NoPin for I2C and SPI on BTT SKR Pico
* Cleanup comments
* Don't use ADC pin names
For the threads scheduler, it makes sense to have NumCPU available.
For all other schedulers, the number of available CPUs is practically
limited to one by the scheduler (even though the system might have more
CPUs).
Instead of relying on a build when TinyGo is being built, do it like all
other libraries when it is needed.
This brings a few benefits:
* No more running `make wasi-libc` on the command line as a special
case for WebAssembly. The generic `git submodule update --init` step
is now enough for wasi-libc.
* It becomes much easier to customize the build per system. For
example: include/exclude malloc as needed, disable/enable bulk
memory operations per target, etc.
This *should* not be needed. Using the right `go` binary should do the
job. It might break if users have explicitly set GOROOT (in which case
they probably need to fix that).
This avoids a subprocess call inside `make`.
Instead of calling it 5 times, call it only once on Unix-like systems
(Linux, MacOS) and avoid it entirely on Windows.
The main benefit of this is that it avoids a ton of overhead doing
subprocess calls, which are very slow on Windows (~0.2s on my system).
Most make commands don't need to check for the NodeJS version, so only
do it when needed.
This avoids the following error on Windows for example when NodeJS is
not installed:
/usr/bin/sh: line 1: node: command not found
which: no node in (/c/Users/Ayke/bin:/clangarm64/bin:/usr/local/bin:/usr/bin:/usr/bin:/mingw64/bin:/usr/bin:/c/Users/Ayke/bin:/c/Users/Ayke/.vscode-server/cli/servers/Stable-e54c774e0add60467559eb0d1e229c6452cf8447/server/bin/remote-cli:/c/WINDOWS/system32:/c/WINDOWS:/c/WINDOWS/System32/Wbem:/c/WINDOWS/System32/WindowsPowerShell/v1.0:/c/WINDOWS/System32/OpenSSH:/cmd:/c/Users/Ayke/scoop/apps/mingw-mstorsjo-llvm-ucrt/current/bin:/c/Users/Ayke/scoop/apps/python/current/Scripts:/c/Users/Ayke/scoop/apps/python/current:/c/Users/Ayke/go/bin:/c/Users/Ayke/scoop/shims:/c/Users/Ayke/AppData/Local/Microsoft/WindowsApps:/usr/bin/vendor_perl:/usr/bin/core_perl)
Also, some users have been confused by the error message even though in
most cases it is harmless and can be ignored.
A few small changes were needed to make this work. In particular, I
found a critical bug (see the previous commit) that needed to be fixed
to make this work on Windows.
This adds support for the well-known Boehm GC. It's significantly faster
than our own naive GC and could be used as an alternative on bigger
systems.
In the future, this GC might also be supported on WebAssembly with some
extra work. Right now it's Linux only (though Windows/MacOS shouldn't be
too difficult to add).
Run a range of tests in CI, to make sure browser wasm and baremetal
don't regress too badly.
I have intentionally filtered out tests, so that newly added tests to
TEST_PACKAGES_FAST will be added here as well (and can be excluded if
needed).
It looks like we didn't have any tests for wasm. Having one tests is not
much, but it proves that the infrastructure works and it actually
verifies a fix to https://github.com/tinygo-org/tinygo/issues/4777.
We should add more packages to this list in the future.
Right now it doesn't compile, with errors like the following:
# machine
/app/tinygo/src/machine/board_pico.go:7:13: undefined: GPIO0
/app/tinygo/src/machine/board_pico.go:8:13: undefined: GPIO1
/app/tinygo/src/machine/board_pico.go:9:13: undefined: GPIO2
/app/tinygo/src/machine/board_pico.go:10:13: undefined: GPIO3
[...etc...]
This patch should fix that.
* initial implementation for Tillitis TKey device
* add UART implementation for TKey
* add Pin interface implementation for TKey touch sensor
* add RNG interface implementation for TKey
* add helpful machine package functions to return identifiers such as name and version for TKey
* use built-in timer for sleep timing on TKey
* modify UART implementation for TKey to implement Serialer interface
* implement BLAKE2s ROM function call for TKey device
* handle abort by triggering TKey device fault using illegal instruction to halt CPU
* simplify TKey implementation by inheriting from existing riscv32 target
* return error for trying to configure invalid baudrates on UART
* add tkey to builder test
* be very specific for features passed to LLVM for specific config in use for TKey
* handle feedback items from TKey device code review

This requires an API introduced in MacOS 11. I think that's fine, since
the version before that (MacOS 10.15) is EOL since 2022. Though if
needed, we could certainly work around it by using an older and slightly
less nice API.
