cgo: add support for printf #4101

aykevl · 2024-01-27T12:13:50Z

The C printf function is sometimes needed for C files included using CGo. This PR makes sure they're available on all systems where CGo is fully supported (that is, everywhere except on AVR).

For baremetal systems using picolibc, I've picked the integer-only version of printf to save on flash size. In the future we might want to consider providing a way to pick the floating point version instead, if needed.

See, that's why I added this test a while back. This should not have resulted in a code size change, yet it does.

EDIT: this is llvm/llvm-project#52

Found one remaining issue, which appears to be a wasmtime bug: bytecodealliance/wasmtime#7833
EDIT: worked around it for now, using fflush (no idea why that works, but it's a temporary workaround until the root cause is found).

This updates the list of builtins to the one in LLVM 17 (which is our current version) and addes GENERIC_TF_SOURCES, which contains long double floating point builtins (80 bit, 128 bit, etc). This is needed for full printf support in the next commit.

@aykevl there still appears to be some issue with the Windows build on this PR.

This flushes stdio, so that functions like puts and printf write out all buffered data even if the output isn't connected to a terminal. For discussion, see: bytecodealliance/wasmtime#7833

@aykevl there still appears to be some issue with the Windows build on this PR.

Yeah, I think I need to debug this on an actual Windows system.

The C printf function is sometimes needed for C files included using CGo. This commit makes sure they're available on all systems where CGo is fully supported (that is, everywhere except on AVR). For baremetal systems using picolibc, I've picked the integer-only version of printf to save on flash size. We might want to consider providing a way to pick the floating point version instead, if needed.

aykevl · 2024-02-27T14:48:17Z

That CI failure should be fixed now. I just had to fix this one line:

 		if err != nil {
 			return BuildResult{}, err
 		}
-		unlock()
+		defer unlock()
 		libcDependencies = append(libcDependencies, job)
 		libcDependencies = append(libcDependencies, makeMinGWExtraLibs(tmpdir, config.GOARCH())...)
 	case "":

No idea why only this library didn't have the defer while the others did.
