Hi Sebastien,

At 723afeea, https://git.sr.ht/~sbinet/star-tex/tree/main/item/font/fixed/int12_20.go#L33
and https://git.sr.ht/~sbinet/star-tex/tree/main/item/font/fixed/int16_16.go#L31
there are conversions from float64 to a type based on uint32, ie. an
unsigned type. Those conversions are not guaranteed to work when the
number is out of range for the target type, but it is CPU-specific. On
linux/arm it seems the CPU conversion instruction converts negative
float64 values to uint32(0) and the test fails, see
https://gitlab.com/cznic/builder/-/raw/master/logs/modernc.org/knuth/pi32.

Please see the fix just pushed in
https://gitlab.com/cznic/knuth/-/commit/ae0b147fc8ba5da8093ad4b136b0f3a51409ff61
that resolved the issue. I suggest incorporating it upstream in

Hi Sebastien.

staticcheck noticed this:
https://git.sr.ht/~sbinet/star-tex/tree/main/item/cmd/dvi-cnv/png.go#L68

I'm not able to figure out if the value of the computation should be
used somehow or if it is perhaps some leftover from a debug session or
something else.

Best,

libqbe is a Go package wrapping the [transpiled to Go] QBE command.

Thanks for replying!

On my system it seems to be not set.

I was not able to run $ make check, see the terminal session below:
