* GNUmakefile: split into topic files in make/
The GNUmakefile had 1295 lines and mixed build configuration, LLVM
bootstrapping, device generation, four test suites, the smoke tests,
release packaging, and lint tools. The smoke tests alone were 500 lines.
Move each part into its own file in make/ and include them from
GNUmakefile. config.mk must be included first because the other files
use its variables in immediate assignments and conditionals.
There is no change in behavior. The parsed make database is identical
for the default build and for ASSERT=1, STATIC=1, XTENSA=0, STM32=0,
WASM=0, and CROSS=aarch64-linux-gnu, except for MAKEFILE_LIST and the
.PHONY list, which now also includes targets that were phony but not
declared.
The Dockerfile copies GNUmakefile alone before it builds LLVM, to keep
that layer independent of the source tree. It must copy make/ too.
* make/smoketest.mk: split into groups and add smoketest-quick
The smoke test was one recipe of about 500 lines with 236 builds that
always ran in sequence. Split it at the group boundaries that were
already there, so that:
- `make -j smoketest` builds the groups in parallel. A full run goes
from 325 to 91 seconds on a 32 core machine.
- CI can shard the groups across runners.
Each group writes to its own name in build/smoke/, because all builds
wrote to test.hex before and would overwrite each other in a parallel
build. The output extension selects the format, so it stays per line.
Add smoketest-quick, which builds one board for each processor
architecture. The full smoke test answers "can TinyGo build for every
board", which does not depend on the host OS, so it only needs to run
on one OS. The other jobs use smoketest-quick.
The comment above the esp32c3 group had 4 spaces of indentation instead
of a tab. That was harmless in the middle of a recipe, but it is now the
first line of a group, where it would stop the recipe from starting.
The set of build commands is unchanged for the default flags and for
XTENSA=0, STM32=0, and WASM=0. All 226 checksums are the same as before,
for a sequential build and for `make -j16`.
* ci: run the full smoke test once, on Linux only
The smoke test ran six times for each push: twice on Linux, twice on
macOS, once on Windows, and once in the compatibility test. Together
that was about 97 minutes of the CI time.
The smoke test checks that TinyGo can build a binary for each board.
That does not depend on the host OS. The only part that does is one
build behind a Windows check.
Add a smoketest-linux job that runs the full set, split across four
runners that use the tarball from the build-linux job. The groups are
balanced with the measured build time of each group. Remove the full
smoke test from test-linux-build, which the new job replaces, and use
smoketest-quick for the other four jobs.
Expected result: about 55 to 39 minutes for the slowest workflow, and
about 97 to 35 minutes of total smoke test time.
* make/smoketest.mk: build nintendoswitch in smoketest-quick
It is the only target that uses the aarch64 LLVM triple. With it,
smoketest-quick covers all 13 triples that the full smoke test uses.
Example output:
$ make help
clean Remove build directory
fmt Reformat source
fmt-check Warn if any source needs reformatting
gen-device Generate microcontroller-specific sources
llvm-source Get LLVM sources
llvm-build Build LLVM
lint Lint source tree
spell Spellcheck source tree
Might even work on windows, since git for windows comes with awk.
Go 1.18 has been unsupported for quite a while now (the oldest supported
version is Go 1.21). But more importantly, the golang.org/x/tools module
now requires Go 1.19 or later. So we'll drop this older version.
It's not generally needed. It was added in
https://github.com/tinygo-org/tinygo/pull/3958 to fix an issue with
binaryen that has since been fixed in a different way, so we don't need
the googletest dependency anymore.
1.15 specific files deleted.
1.16 specific files folded carefully into generic files, with goal of reducing diff with upstream.
Follows upstream 1.16 in making PathError etc. be aliases for the same errors in io/fs.
This fixes#2817 and lets us add io/ioutil to "make test-tinygo" on linux and mac.
The BUILDING.md file is not intended for developer builds but for
release builds. The website contains more specific and more complete
information on how to build TinyGo, so provide links to these pages.
The Windows link doesn't work yet, but should work with the next
release when we update the website.
This replaces the older way which just does the following:
go install .
and
go test -v .
Instead, `make` and `make test` will now build TinyGo statically linked
against LLVM, so that `go install` and `go test -v` should be used
manually.
When building statically against LLVM, LLD is also included now. When
included, the built in wasm-ld will automatically be used instead of the
external command.
There is also support for linking ELF files but because lld does not
fully support armv6m this is not yet enabled (it produces a warning).
