Detailed Description
code == GIMPLE_SWITCH
GIMPLE_SWITCH <INDEX, DEFAULT_LAB, LAB1, ..., LABN> represents the multiway branch:
switch (INDEX) { case LAB1: ...; break; ... case LABN: ...; break; default: ... }
INDEX is the variable evaluated to decide which label to jump to.
DEFAULT_LAB, LAB1 ... LABN are the tree nodes representing case labels. They must be CASE_LABEL_EXPR nodes.

[ WORD 3 ] Basic block holding this statement.
Referenced by gimple_call_arg_flags().
|
inherited |
Nonzero if this statement contains volatile operands.
|
inherited |
[ WORD 2 ] Locus information for debug info.
|
inherited |
Nonzero if this statement has been modified and needs to have its operands rescanned.
|
inherited |
[ 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.
|
inherited |
Nonzero if this tuple represents a non-temporal move.
|
inherited |
Number of operands in this tuple.

[ WORD 1-7 ] : base class [ WORD 8 ] Operand vector. NOTE! This must always be the last field of this structure. In particular, this means that this structure cannot be embedded inside another one.

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.
|
inherited |
[ WORD 1-6 ] : base class [ WORD 7 ] SSA operand vectors. NOTE: It should be possible to amalgamate these vectors with the operand vector OP. However, the SSA operand vectors are organized differently and contain more information (like immediate use chaining).

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