nx_uleb.nx

nx_uleb.nx -- LEB128 (unsigned + signed) encoders + decoders. LEB128 (Little Endian Base 128) is a variable-length integer encoding used by DWARF, WebAssembly, Android dex, the MQTT protocol, and many others. Each byte carries 7 bits of payload plus a continuation bit (high bit) indicating "more bytes follow". Encoding rules: uleb128: - Take the low 7 bits, OR with 0x80 if more bits remain. - Shift right by 7, repeat until value is 0. sleb128: - Same, but stop when the remaining value is 0 AND the sign bit of the last 7-bit chunk is 0 (or value is -1 and the sign bit is 1). Today nx_dwarf_line.nx, nx_dwarf_loc.nx, and nx_dwarf_aranges.nx each have their own copies of these. This module is the single source of truth. As the off-C runtime grows new LEB128 consumers (WebAssembly support, dex parsing, BPF), they import here.
