So, tests are currently failing. A bunch of tests I've fixed after realising that the underlying problem is with how we do comparisons when we have a bitshift with an untyped integer on the lhs: #1462 (comment) I suspect there may be more bugs involved. In any case, I attempted to make a separate branch from this which merged in the changes from #1426. Turns out, that the tests are completely passing with that code applied to Gno. So, I'll be continuing work on this once #1426 is merged. For the meantime, I'll update the OP to mark what remaining work is to be done to complete this PR so I can easily pick it up later. |
I did this as an experiment, it passes all the test after making a small adjustment on your code, |

strconvpackage, implemented as pure Gno code. It removes the native functionsItoa(and others), and adds support for new functions such asFormatFloat.Summary of changes
strconvfrom Go stdlib: https://gist.github.com/thehowl/904b42b1ea53fef9b8a0486155c02b73 -- tldr:unicodestrconvtests succeed.unicode/utf8fallback(as we now half-support it) and useAppendString.store.go,store_test.go,nodes.go,tests/imports.go.gonative.goandmachine.gochanges improve some error messages.preprocess.gochanges fix a bug which can be seen in thefor20.gnotest. If aforloop is labeled, then a barebreak(ie. without a label to break to) would panic, as it wouldn't find any for loop without a label (infindBranchLabel). I added a regression test as well as a couple test showing the error message for when we misplace continue/break statements.strconv.Itoanow uses more gas than its existing native implementation. This is to be expected; we can consider moving it back to a native implementation if we deem it useful for performance, but I think it's good for us to work on having as much code implemented directly in gno before moving it back to Go for performance.
