Only trivial functional changes:
- gets rid of mistaken extra "no tests" warning (whoops)
- matches upstream's exit code better
In preparation for switching to fancy test filtering.
The scoop and brew package managers now bundle up-to-date copies of binaryen.
As a result, there is no longer a strong need for us to build and package our own copy.
On wasi, O_RDWR is a bitwise or of read and write mode.
As a result, the bit test result was incorrect, and rewrote it to read-write mode.
However, the bit tests are not necessary (and upstream Go does not use them).
This passes the flags through directly.
This change updates the test runner to use exec.CommandContext for timeout handling.
The timeout has been raised to 1 minute to handle slow machines and (hopefully) Windows.
The test run also now acquires the semaphore to reserve CPU time for the test and (hopefully?????) reduce the number of timeouts in Windows CI.
The AVR backend has several critical atomics bugs.
This change invokes libcalls for all atomic operations on AVR.
Now `testdata/atomic.go` compiles and runs correctly.
Some clang builds (e.g., Fedora's) enable unwind tables by default. As
tinygo does not need nor support them, that leads to undefined symbols
when linking.
Arch Linux stores the clang executable seperately from its data, so the search based on the executable does not work.
This change searches /usr/lib as a backup.
Arch Linux has turned on the stack protector by default.
This causes a crash in libc init because the stack protector uses TLS before it is initialized.
This adds support for building with `-tags=llvm13` and switches to LLVM
13 for tinygo binaries that are statically linked against LLVM.
Some notes on this commit:
* Added `-mfloat-abi=soft` to all Cortex-M targets because otherwise
nrfx would complain that floating point was enabled on Cortex-M0.
That's not the case, but with `-mfloat-abi=soft` the `__SOFTFP__`
macro is defined which silences this warning.
See: https://reviews.llvm.org/D100372
* Changed from `--sysroot=<root>` to `-nostdlib -isystem <root>` for
musl because with Clang 13, even with `--sysroot` some system
libraries are used which we don't want.
* Changed all `-Xclang -internal-isystem -Xclang` to simply
`-isystem`, for consistency with the above change. It appears to
have the same effect.
* Moved WebAssembly function declarations to the top of the file in
task_asyncify_wasm.S because (apparently) the assembler has become
more strict.
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 matches what upstream Go does. This also means len(b) == 0 successfully
reads 0 bytes without any extra logic. The tests in archive/zip test for this
behaviour.
Large object layouts don't fit in a pointer-sized integer and therefore
need to be stored in a global instead. However, the way the data was
stored in these globals was not correct for buffers that don't have
pointers near the end. This commit fixes this issue by using math/big
FillBytes() instead of Bytes().
This gets the unicode package to compile on AVR.
