This file has one entry for each public pattern name that the target
can provide.  It is only used if no distinction between operand modes
is necessary.  If separate patterns are needed for different modes
(so as to distinguish addition of QImode values from addition of
HImode values, for example) then an optab should be used instead.

Each entry has the form:

  DEF_TARGET_INSN (name, prototype)

where NAME is the name of the pattern and PROTOTYPE is its C prototype.
The prototype should use parameter names of the form "x0", "x1", etc.
for the operands that the .md pattern is required to have, followed by
parameter names of the form "optN" for operands that the .md pattern
may choose to ignore.  Patterns that never take operands should have
a prototype "(void)".

Pattern names should be documented in md.texi rather than here.

parse_argument()

static bool parse_argument ( const char * p, const char ** end_out, unsigned int * opno_out = 0, bool * required_out = 0 )

static

Return true if the part of the prototype at P is for an argument
name.  If so, point *END_OUT to the first character after the name.
If OPNO_OUT is nonnull, set *OPNO_OUT to the number of the associated
operand.  If REQUIRED_OUT is nonnull, set *REQUIRED_OUT to whether the
.md pattern is required to match the operand.
