pub fn parse_xreg(raw: &str) -> Option<String>Expand description
Parse a raw operand string into a canonical AArch64 GPR name.
Accepts the textual forms r2 emits (x0, w0, xzr, wzr,
optional whitespace, optional , from the operand splitter) and
returns the lower-cased canonical name. Returns None for the
stack-pointer aliases (sp, wsp) — patching them is unsafe in
the general case (function epilogues, frame setup), and for any
other shape (SIMD registers, memory operands, immediates).
