Detailed Description
code == GIMPLE_PHI:
GIMPLE_PHI <RESULT, ARG1, ..., ARGN> represents the PHI node
RESULT = PHI <ARG1, ..., ARGN>
RESULT is the SSA name created by this PHI node.
ARG1 ... ARGN are the arguments to the PHI node. N must be exactly the same as the number of incoming edges to the basic block holding the PHI node. Every argument is either an SSA name or a tree node of class tcc_constant.

Nonzero if this statement contains volatile operands.

[ WORD 2 ] Locus information for debug info.

Nonzero if this statement has been modified and needs to have its operands rescanned.

[ WORD 4-5 ] Linked lists of gimple statements. The next pointers form a NULL terminated list, the prev pointers are a cyclic list. A gimple statement is hence also a double-ended list of statements, with the pointer itself being the first element, and the prev pointer being the last.

[ WORD 1 ] Main identifying code for a tuple. Nonzero if a warning should not be emitted on this tuple.

Nonzero if this tuple represents a non-temporal move.

Number of operands in this tuple.

Pass local flags. These flags are free for any pass to use as they see fit. Passes should not assume that these flags contain any useful value when the pass starts. Any initial state that the pass requires should be set on entry to the pass. See gimple_set_plf and gimple_plf for usage.

The SUBCODE field can be used for tuple-specific flags for tuples that do not require subcodes. Note that SUBCODE should be at least as wide as tree codes, as several tuples store tree codes in there.

UID of this statement. This is used by passes that want to assign IDs to statements. It must be assigned and used by each pass. By default it should be assumed to contain garbage.

Nonzero if this tuple has been visited. Passes are responsible for clearing this bit before using it.
