Opcodes, Opcode Types, and Opcode Flags ---------------------------------------
Description:
This file includes opcode_core.h (see the interface there) and provides some accessing functions to the data. It is split like this because the accessors call FmtAssert() and other routines that non-compiler passes might want to avoid.
This file should be updated whenever opcode_gen is updated. opcode_gen is a perl file that is somewhat readable -- if the comments get out of date here, one can always look there (and bring them up to date).
Exported Functions:
OPCODE OPCODE_make_op( OPERATOR opr, TYPE_ID rtype, TYPE_ID desc )
Given the operator, rtype and desc type, return the opcode. The opr, rtype and desc MUST map to a valid OPCODE. Otherwise, the compilation terminates with an internal error.
const char *OPCODE_name(OPCODE op)
Returns a string representation of the opcode.
const char *OPERATOR_name(OPERATOR opr)
Returns a string representation of the operator.
The remaining exported functions are actually not declared in this file but in the automatically generated include files.
mINT8 OPCODE_nkids(OPCODE op)
Returns the number of kids this opcode must have, or -1 if not fixed, i.e. call, array, return.
The following exported functions return 0 if the opcode does not have the stated property. Otherwise, the value returned is non-zero.
UINT32 OPCODE_is_scf(OPCODE op)
Opcode is OPR_FUNC_ENTRY, OPR_BLOCK, OPR_DO_LOOP, OPR_DO_WHILE, OPR_WHILE_DO, OPR_IF.
UINT32 OPCODE_is_stmt(OPCODE op)
Opcode occurs at top of an expression tree, e.g. a store, call, goto, pragma, etc. No structured control flow falls in this category.
UINT32 OPCODE_is_expression(OPCODE op)
Opcode occurs underneath a statement, e.g. OPR_DADD.
UINT32 OPCODE_is_leaf(OPCODE op)
Opcode is an expression or statement that never has children. Note that OPR_RETURN is not a leaf, since it may have children.
UINT32 OPCODE_is_load(OPCODE op) UINT32 OPCODE_is_store(OPCODE op)
Opocde gets memory, e.g. ILOAD, MLOAD, LDID, etc (or store) Goto, branch, label, altentry
UINT32 OPCODE_is_call(OPCODE op)
Intrinsic call or regular, but not an intrinsic op.
UINT32 OPCODE_is_compare(OPCODE op)
Comparison, e.g. GE
UINT32 OPCODE_is_non_scf(OPCODE op)
Opcode directly relates to control flow, but is not structured. Goto, branch, label, altentry
UINT32 OPCODE_is_boolean(OPCODE op)
Boolean return value, e.g. a comparison.
UINT32 OPCODE_is_endsbb(OPCODE op)
Call, a goto, branch, call, return.
UINT32 OPCODE_is_comp_unit_if(OPCODE op)
Compilation unit interface, e.g. REGION
UINT32 OPCODE_is_not_executable(OPCODE op)
Currently PRAGMA, COMMENT, LABEL and OPT_ opcodes.
UINT32 OPCODE_is_prefetcn(OPCODE op)
Obvious.
OPCODE OPCODE_commutative_op(OPCODE op)
Return an opcode op1 such that x op y is y op1 x. If none exists, return (OPCODE) 0.
The following exported functions describe qualities of the WN that has this opcode. E.g. OPCODE_has_sym(op) indicates that a WN holding this opcode also holds an ST_IDX.
UINT32 OPCODE_has_next_prev(OPCODE op) UINT32 OPCODE_has_sym(OPCODE op) UINT32 OPCODE_has_label(OPCODE op) UINT32 OPCODE_has_num_entries(OPCODE op) UINT32 OPCODE_has_offset(OPCODE op) UINT32 OPCODE_has_bits(OPCODE op) UINT32 OPCODE_has_ndim(OPCODE op) UINT32 OPCODE_has_esize(OPCODE op) UINT32 OPCODE_has_value(OPCODE op) UINT32 OPCODE_has_flags(OPCODE op) UINT32 OPCODE_has_inumber(OPCODE op) UINT32 OPCODE_has_1ty(OPCODE op) UINT32 OPCODE_has_2ty(OPCODE op)
The 'has' fields indicate which fields of a WN are used.
OPCODE_MAPCAT OPCODE_mapcat(OPCODE op)
Annotation category of an opcode. Current values are OPCODE_MAPCAT_{HDR,SCF,LDST,PRAGMA,OSTMT,OEXP,ARRAY,CALL}.
