Makes 1.18 tests a little happier.
Works around this error:
$ make test GOTESTFLAGS="-run TestTest/EmulatedCortexM3/Pass"
...
main_test.go:520: test error: could not compile: /usr/local/go/src/internal/fuzz/sys_posix.go:19:18: PROT_READ not declared by package syscall
This adds the `Version()` function of the `runtime` package which embeds
the go version that was used to build tinygo.
For programs that are compiled with tinygo the version can be overriden
via the:
`tinygo build -ldflags="-X 'runtime.buildVersion=abc'"` flag.
Otherwise it will continue to use the go version with which tinygo was
compiled.
This test creates a new temp file and writes some bytes into it.
It then opens a new file for the file descriptor of the temp file and
tries to read some bytes out of it.
These are used in Go 1.18's `testing/internal/testdeps`. Though the
comment says they should exist _everywhere_, there is still a build
constraint, but that seems to be fine.
Update interrupt_esp32c3.go:
make callHandler inline
save and restore MSTATUS along with MEPC
save and restore actual threshold value and call fence
print additional data during exception
This commit adds stubs for the `ExitError` struct of the `exec` package
and `ProcessState.ExitCode()` of the `os` package.
Since the `os/exec` is listed as unsupported, stubbing these methods
and structs should be enough to get programs that use these to compile.
This adds a stub for the `NumCPU()` function from the `runtime`
package.
This change allows code to compile that tries to access this function.
I guess for most hardware boards and WASM setting this value to `1` is
fine. And as far as I can see it shouldn't break or change existing
applications, because the function previously did not exist at all.
This adds the necessary structs and the `ReadBuildInfo()` function to
the runtime/debug module to allow to compile code that tries to access
it.
The stub itself returns ok=false, so that calling code should not try
to read from the nil pointer that is returned instead of the actual
BuildInfo struct.
This function is used by the hash/maphash package.
Unfortunately, I couldn't get the hash/maphash package to pass tests
because it's too slow. I think it hits the quadratic complexity of the
current map implementation.
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.
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.
