Memory references (`*m` in LLVM IR inline assembly) need a pointer type
starting in LLVM 14. This is a bit inconvenient and requires a new API
in the go-llvm package.
Instead of doing that, I'd like to remove support for memory references
from AsmFull (and possibly AsmFull entirely if possible: it's hard to
use correctly).
This breaks tinygo.org/x/drivers/ws2812 for AVR, ARM, and RISC-V which
need to be updated. Probably using CGo.
Evidently when you read from pipes in Go, you have to adjust your slice length to reflect the number of bytes read.
Verified upstream behaves the same way.
Grepped straight out of the appropriate signal.h, with order preserved.
Makes 1.18 tests happier.
See comment on discrepancy for SIGCHLD. Since wasi doesn't really support signals, this may not matter.
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.
