Currently, an expression like @code{a = b + 5} is not reduced any
further. We tried converting it to something like
@smallexample
- T1 = b + 5;
- a = T1;
+T1 = b + 5;
+a = T1;
@end smallexample
but this bloated the representation for minimal benefit. However, a
variable which must live in memory cannot appear in an expression; its
variable. More complex operands are factored out into temporaries, so
that
@smallexample
- a = b + c + d
+a = b + c + d
@end smallexample
becomes
@smallexample
- T1 = b + c;
- a = T1 + d;
+T1 = b + c;
+a = T1 + d;

+tree value, gimple stmt)
+Build a @code{GIMPLE_DEBUG} statement with @code{GIMPLE_DEBUG_BIND}
+@code{subcode}. The effect of this statement is to tell debug
+information generation machinery that the value of user variable
+@code{var} is given by @code{value} at that point, and to remain with
+that value until @code{var} runs out of scope, a
+dynamically-subsequent debug bind statement overrides the binding, or
+conflicting values reach a control flow merge point. Even if
+components of the @code{value} expression change afterwards, the
+variable is supposed to retain the same value, though not necessarily
+the same location.
+
+It is expected that @code{var} be most often a tree for automatic user
+variables (@code{VAR_DECL} or @code{PARM_DECL}) that satisfy the
+requirements for gimple registers, but it may also be a tree for a
+scalarized component of a user variable (@code{ARRAY_REF},
+@code{COMPONENT_REF}), or a debug temporary (@code{DEBUG_EXPR_DECL}).
+
+As for @code{value}, it can be an arbitrary tree expression, but it is
+recommended that it be in a suitable form for a gimple assignment
+@code{RHS}. It is not expected that user variables that could appear
+as @code{var} ever appear in @code{value}, because in the latter we'd
+have their @code{SSA_NAME}s instead, but even if they were not in SSA
+form, user variables appearing in @code{value} are to be regarded as
+part of the executable code space, whereas those in @code{var} are to
+be regarded as part of the source code space. There is no way to
+refer to the value bound to a user variable within a @code{value}
+expression.
+
+If @code{value} is @code{GIMPLE_DEBUG_BIND_NOVALUE}, debug information
+generation machinery is informed that the variable @code{var} is
+unbound, i.e., that its value is indeterminate, which sometimes means
+it is really unavailable, and other times that the compiler could not

The first step in adding a new GIMPLE statement code, is
modifying the file @code{gimple.def}, which contains all the GIMPLE
-codes. Then you must add a corresponding structure, and an entry
-in @code{union gimple_statement_d}, both of which are located in
-@code{gimple.h}. This in turn, will require you to add a corresponding
-@code{GTY} tag in @code{gsstruct.def}, and code to handle this tag in

+this tag in @code{gss_for_code} which is located in @code{gimple.cc}.
In order for the garbage collector to know the size of the
structure you created in @code{gimple.h}, you need to add a case to
handle your new GIMPLE statement in @code{gimple_size} which is located

+in @code{gimple.cc}.
You will probably want to create a function to build the new

If your new statement requires accessors for any members or
operands it may have, put simple inline accessors in

There are two functions available for walking statements and
sequences: @code{walk_gimple_stmt} and @code{walk_gimple_seq},
accordingly, and a third function for walking the operands in a
statement: @code{walk_gimple_op}.
