This appears to have been how it is upstream for about 10 years. Using
an interface breaks if a file descriptor number is passed directly to
`NewFile`, e.g., `NewFile(3, "fuzz_in")` as used in Go 1.18 fuzzing
code.
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.
The register r0 was used unconditionally. This is a bug: the compiler
doesn't know it is clobbered and might consider it alive across the
inline assembly expression.
The fix is simple. It could probably be optimized, but this should at
least fix the bug.
This means that it will be possible to generate a Darwin binary on any
platform (Windows, Linux, and MacOS of course), including CGo. Of
course, the resulting binaries can only run on MacOS itself.
The binary links against libSystem.dylib, which is a shared library. The
macos-minimal-sdk repository contains open source header files and
generated symbol stubs so we can generate a stub libSystem.dylib without
copying any closed source code.
It should only be added at the point that it is needed, for example when
using libclang or using the built-in Clang. It isn't needed when running
an external tool.
Do it all at once in preparation for Go 1.18 support.
To make this commit, I've simply modified the `fmt-check` Makefile
target to rewrite files instead of listing the differences. So this is a
fully mechanical change, it should not have introduced any errors.
This would conflict with our own heap. We previously defined all those
functions to make sure it's not used, but with a more recent wasi-libc
version (https://github.com/WebAssembly/wasi-libc/pull/250) we can
simply not compile the wasi-libc heap, which is the proper fix.
It's wafer-thin :-)
Includes smoke test from upstream.
TODO: once t.TempDir is implemented, add io/fs to the list of standard library tests to run; that's a better test.
readdir is disabled on linux for 386 and arm until syscall.seek is implemented there.
windows is hard, so leaving that for later.
File src/os/dir_other_go115.go can be deleted when we drop support for go 1.15.
Also adds TestReadNonDir, which was helpful while debugging.
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.
On Ubuntu, using standard go, both go and gnu buildid sections are present.
On Alpine, the gnu buildid section is absent, which caused tinygo to abort early.
It is possible that we could hit a situation where only the gnu
buildid section is present, so accept either one just in case.
Fixes https://github.com/tinygo-org/tinygo/issues/2580
This replaces an earlier kludge which was at the wrong level
and caused "GOARCH=386 tinygo test os" to fail to compile on linux.
Stubbing just the one missing function, syscall.seek, lets
os tests compile on linux 386, and skipping tests of seek and Fstat
(which has a cryptic dependency on syscall.Seek via time)
lets os tests pass on linux 386.
The stub can be removed once tinygo implements go assembly and picks up the real definition.
