I think it is more confusing than helpful because it is only relevant
when compiling an actual linux/arm binary (and in that case, it is also
included in the LLVM triple).
See: https://github.com/tinygo-org/tinygo/issues/3034
This should add support for things like quotes around tags, if they are
ever needed.
Only making this change now because I happened to stumble across
buildutil.TagsFlag.
This matches the flash-command and is generally a bit easier to work
with.
This commit also prepares for allowing multiple formats to be used in
the emulator command, which is necessary for the esp32.
This means that we don't need duplicate code to pass parameters to
wasmtime and that the following actually produces verbose output (it
didn't before this commit):
tinygo test -v -target=cortex-m-qemu math
Refactor the code that runs a binary. With this change, the slightly
duplicated code between `tinygo run` and `TestBuild` is merged into one.
Apart from deduplication (which doesn't even gain much in terms of lines
removed), it makes it much easier to maintain this code. In particular,
passing command line arguments to programs to run now becomes trivial.
A future change might also merge `buildAndRun` and `runPackageTest`,
which currently have some overlap. In particular, flags like `-test.v`
don't need to be special-cased for wasmtime.
Moving and exporting this variable from the main to the goenv package
allows us to use it from both the main and the builder package.
This is done in preparation to include the value in `tinygo build`
linker flags, so that we can embed the version and git sha into binaries
built with tinygo.
I see no reason why it isn't possible to run `tinygo test -c` with
multiple packages. It'll just create multiple test outputs. I think the
intended flag was the `-o` flag, which indeed doesn't make much sense
with multiple packages.
This subcommand has been broken for a while, since libraries also use
the CPU flag. This commit fixes this.
Previously, libraries were usable for most Cortex-M cores. But with the
addition of the CPU field, I've limited it to three popular cores: the
Cortex-M0 (microbit), Cortex-M0+ (atsamd21), and Cortex-M4 (atsamd21,
nrf52, and many others).
In the future we might consider also building libraries for the current
OS/arch so that libraries like musl are already precompiled.
Also fix a couple os tests that wrote to current directory to write to os.TempDir() instead.
After this, os tests pass in wasi, so add them to the list run by "make tinygo-test-wasi".
This change adds an additional semaphore to tinygo test that limits the number of tests being processed simultaneously (in addition to the existing limit on build jobs and runs).
When running a large number of tests, this limits the number of copies of per-test data stored in memory (avoiding an OOM in CI).
Switching to a shared semaphore allows multi-build operations (compiler tests, package tests, etc.) to use the expected degree of parallelism efficiently.
While refactoring the job runner, the time complexity was also reduced from O(n^2) to O(n+m) (where n is the number of jobs, and m is the number of dependencies).
The extalloc collector has been broken for a while, and it doesn't seem reasonable to fix right now.
In addition, after a recent change it no longer compiles.
In the future similar functionality can hopefully be reintroduced, but for now this seems to be the most reasonable option.
This environment variable can be set to 5, 6, or 7 and controls which
ARM version (ARMv5, ARMv6, ARMv7) is used when compiling for GOARCH=arm.
I have picked the default value ARMv6, which I believe is supported on
most common single board computers including all Raspberry Pis. The
difference in code size is pretty big.
We could even go further and support ARMv4 if anybody is interested. It
should be pretty simple to add this if needed.
This is really just a preparatory commit for musl support. The idea is
to store not just the archive file (.a) but also an include directory.
This is optional for picolibc but required for musl, so the main purpose
of this commit is the refactor needed for this change.
This commit changes `tinygo test` to always look at the exit code of the
running test, instead of looking for a "PASS" string at the end of the
output. This is possible now that the binaries running under
qemu-system-arm or qemu-system-riscv32 will signal the correct exit code
when they exit.
As a side effect, this also makes it possible to avoid the "PASS" line
between successful tests. Before:
$ tinygo test container/heap container/list
PASS
ok container/heap 0.001s
PASS
ok container/list 0.001s
After:
$ tinygo test container/heap container/list
ok container/heap 0.001s
ok container/list 0.001s
The new behavior is more in line with upstream Go:
go test container/heap container/list
ok container/heap 0.004s
ok container/list 0.004s
LLDB mostly works on most platforms, but it is still lacking in some
features. For example, it doesn't seem to support RISC-V yet (coming in
LLVM 12), it only partially supports AVR (no stacktraces), and it
doesn't seem to support the Ctrl-C keyboard command when running a
binary for another platform (e.g. with GOOS=arm64). However, it does
mostly work, even on baremetal systems.
It is better to use environment variables (GOOS and GOARCH) for
consistency instead of providing two slightly incompatible ways. This
-target flag should only be used to specify a .json file (either
directly or in the TinyGo targets directory). Previously it was possible
to specify the LLVM target as well but that was never really fully
supported.
So:
- To specify a different OS/arch like you would in regular Go, use
GOOS and GOARCH.
- To specify a microcontroller chip or board, use the -target flag.
Also remove the old `os.Setenv` which might have had a purpose long ago
but doesn't have a purpose now.
... instead of setting a special -target= value. This is more robust and
makes sure that the test actually tests different arcitectures as they
would be compiled by TinyGo. As an example, the bug of the bugfix in the
previous commit ("arm: use armv7 instead of thumbv7") would have been
caught if this change was applied earlier.
I've decided to put GOOS/GOARCH in compileopts.Options, as it makes
sense to me to treat them the same way as command line parameters.
