Function Documentation
◆ associative_binary_op_p()
| bool associative_binary_op_p | ( | code_helper | code, |
| tree | type ) |
Return true if CODE is a binary operation that is associative when operating on type TYPE.
References associated_internal_fn(), associative_binary_fn_p(), associative_tree_code(), ggc_alloc(), and code_helper::is_tree_code().
Referenced by vectorizable_reduction().
◆ canonicalize_code()
| code_helper canonicalize_code | ( | code_helper | code, |
| tree | type ) |
Return a canonical form for CODE when operating on TYPE. The idea is to remove redundant ways of representing the same operation so that code_helpers can be hashed and compared for equality. The only current canonicalization is to replace built-in functions with internal functions, in cases where internal-fn.def defines such an internal function. Note that the new code_helper cannot necessarily be used in place of the original code_helper. For example, the new code_helper might be an internal function that the target does not support.

◆ commutative_binary_op_p()
| bool commutative_binary_op_p | ( | code_helper | code, |
| tree | type ) |
Return true if CODE is a binary operation and if CODE is commutative when operating on type TYPE.
References associated_internal_fn(), commutative_binary_fn_p(), commutative_tree_code(), ggc_alloc(), and code_helper::is_tree_code().

◆ commutative_ternary_op_p()
| bool commutative_ternary_op_p | ( | code_helper | code, |
| tree | type ) |
Return true if CODE represents a ternary operation and if the first two operands are commutative when CODE is operating on TYPE.
References associated_internal_fn(), commutative_ternary_fn_p(), commutative_ternary_tree_code(), ggc_alloc(), and code_helper::is_tree_code().
◆ first_commutative_argument()
| int first_commutative_argument | ( | code_helper | code, |
| tree | type ) |
If CODE is commutative in two consecutive operands, return the index of the first, otherwise return -1.

◆ get_conditional_internal_fn()
| internal_fn get_conditional_internal_fn | ( | code_helper | code, |
| tree | type ) |
A wrapper around the internal-fn.cc versions of get_conditional_internal_fn for a code_helper CODE operating on type TYPE.

◆ gimple_extract_op()
| bool gimple_extract_op | ( | gimple * | stmt, |
| gimple_match_op * | res_op ) |
Try to describe STMT in RES_OP, returning true on success. For GIMPLE_CONDs, describe the condition that is being tested. For GIMPLE_ASSIGNs, describe the rhs of the assignment. For GIMPLE_CALLs, describe the call.

Return whether OP is a non-expression result and a gimple value.

| gimple_match_op * | res_op, | ||
| gimple_seq * | seq, | ||
| tree(*)(tree) | valueize, | ||
| tree(*)(tree) | top_valueize ) |

◆ maybe_build_generic_op()
| void maybe_build_generic_op | ( | gimple_match_op * | res_op | ) |
If in GIMPLE the operation described by RES_OP should be single-rhs, build a GENERIC tree for that expression and update RES_OP accordingly.
References build1(), build3(), ggc_alloc(), and REF_REVERSE_STORAGE_ORDER.

◆ maybe_push_res_to_seq()
| tree maybe_push_res_to_seq | ( | gimple_match_op * | res_op, |
| gimple_seq * | seq, | ||
| tree | res ) |
Push the exploded expression described by RES_OP as a statement to SEQ if necessary and return a gimple value denoting the value of the expression. If RES is not NULL then the result will be always RES and even gimple values are pushed to SEQ.
