and its operands are more naturally represented as a GIMPLE_CALL
than a GIMPLE_ASSIGN.
- Each entry in this file has the form:
+ Each entry in this file has one of the forms:
DEF_INTERNAL_FN (NAME, FLAGS, FNSPEC)
+ DEF_INTERNAL_OPTAB_FN (NAME, FLAGS, OPTAB, TYPE)
+ DEF_INTERNAL_SIGNED_OPTAB_FN (NAME, FLAGS, SELECTOR, SIGNED_OPTAB,
+ UNSIGNED_OPTAB, TYPE)
+ DEF_INTERNAL_FLT_FN (NAME, FLAGS, OPTAB, TYPE)
+ DEF_INTERNAL_INT_FN (NAME, FLAGS, OPTAB, TYPE)
where NAME is the name of the function, FLAGS is a set of
ECF_* flags and FNSPEC is a string describing functions fnspec.
+ DEF_INTERNAL_OPTAB_FN defines an internal function that maps to a
+ direct optab. The function should only be called with a given
+ set of types if the associated optab is available for the modes
+ of those types. OPTAB says what optab to use (without the trailing
+ "_optab") and TYPE categorizes the optab based on its inputs and
+ outputs. The possible types of optab are:
+
+ - mask_load: currently just maskload
+ - load_lanes: currently just vec_load_lanes
+ - mask_load_lanes: currently just vec_mask_load_lanes
+ - gather_load: used for {mask_,}gather_load
+
+ - mask_store: currently just maskstore
+ - store_lanes: currently just vec_store_lanes
+ - mask_store_lanes: currently just vec_mask_store_lanes
+ - scatter_store: used for {mask_,}scatter_store
+
+ - unary: a normal unary optab, such as vec_reverse_<mode>
+ - binary: a normal binary optab, such as vec_interleave_lo_<mode>
+ - ternary: a normal ternary optab, such as fma<mode>4
+
+ - cond_binary: a conditional binary optab, such as cond_add<mode>
+ - cond_ternary: a conditional ternary optab, such as cond_fma_rev<mode>
+
+ - fold_left: for scalar = FN (scalar, vector), keyed off the vector mode
+ - check_ptrs: used for check_{raw,war}_ptrs
+
+ DEF_INTERNAL_SIGNED_OPTAB_FN defines an internal function that
+ maps to one of two optabs, depending on the signedness of an input.
+ SIGNED_OPTAB and UNSIGNED_OPTAB are the optabs for signed and
+ unsigned inputs respectively, both without the trailing "_optab".
+ SELECTOR says which type in the tree_pair determines the signedness.
+
+ DEF_INTERNAL_FLT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition,
+ the function implements the computational part of a built-in math
+ function BUILT_IN_<NAME>{F,,L}. Unlike some built-in functions,
+ these internal functions never set errno.
+
+ DEF_INTERNAL_INT_FN is like DEF_INTERNAL_OPTAB_FN, but in addition
+ says that the function extends the C-level BUILT_IN_<NAME>{,L,LL,IMAX}
+ group of functions to any integral mode (including vector modes).
+
Each entry must have a corresponding expander of the form:
void expand_NAME (gimple_call stmt)
- where STMT is the statement that performs the call. */
+ where STMT is the statement that performs the call. These are generated
+ automatically for optab functions and call out to a function or macro
+ called expand_<TYPE>_optab_fn. */
