+- The optional flag argument is a constant expression: an OR of the names
+  from `textflag.h`, the table below, a bare number (`4`), or a
+  parenthesised combination (`(NOSPLIT|NOFRAME)`).  Every spelling
+  suppresses exactly what the names suppress.  Without
+  `#include "textflag.h"` the names are not macros and the assembler
+  reports the misleading error `illegal or missing addressing mode for
+  symbol NOSPLIT`: include the header first.  A name outside the table is
+  rejected with the toolchain's wording, and two of the toolchain's own
+  TEXT checks fire here: `ABIInternal requires NOSPLIT`, and
+  `NOFRAME functions must have a frame size of 0` for a positive frame.
 - `$framesize-argsize` is two constants, not a subtraction: the local frame
   size in bytes, and the caller's argument area in bytes. The argument size
   may be omitted entirely, `$16`, which marks the argument size unknown
