These instruction formats take immediate lane index operands. We store these as u8 fields and require them to be in decimal format in the source. No hexadecimal lane indexes are supported.
Parser tests ============ This directory contains test cases for the Cretonne IL parser. Each test case consists of a `foo.cton` input file and a `foo.ref` reference output file. Each input file is run through the `cton-util cat` command, and the output is compared against the reference file. If the two are identical, the test passes.
