static void check_constraint_len ( )

static

Verify that DEFAULT_CONSTRAINT_LEN is used properly and not
   tampered with.  This isn't bullet-proof, but it should catch
   most genuine mistakes.

Variable Documentation

struct constraint_data* constraints_by_letter_table[1<< CHAR_BIT]

static

struct data* idata = &nothing

static

This variable points to the first link in the insn chain.

struct data** idata_end = &nothing.next

static

This variable points to the end of the insn chain.  This is where
   everything relevant from the machien description is appended to.

const char indep_constraints[] = ",=+%*?!#&<>EFVXgimnoprs"

static

This is a complete list (unlike the one in genpreds.c) of constraint
   letters and modifiers with machine-independent meaning.  The only
   omission is digits, as these are handled specially.

Referenced by note_constraint(), and validate_insn_alternatives().

int next_code_number

static

insns in the machine description are assigned sequential code numbers
   that are used by insn-recog.c (produced by genrecog) to communicate
   to insn-output.c (produced by this program).

int next_index_number

static

This counts all definitions in the md file,
   for the sake of error messages.
