I see following in c-tree.texi.
@item LOOP_EXPR
These nodes represent ``infinite'' loops. The @code{LOOP_EXPR_BODY}
represents the body of the loop. It should be executed forever,
unless
an @code{EXIT_EXPR} is encountered.
@item EXIT_EXPR
These nodes represent conditional exits from the nearest enclosing
@code{LOOP_EXPR}. The single operand is the condition; if it is
nonzero, then the loop should be exited. An @code{EXIT_EXPR} will
only
appear within a @code{LOOP_EXPR}.
They are in c-tree.texi because they are now GENERIC, not GIMPLEtrees.
GIMPLE lowers LOOP_EXPRS.
He asked about using LOOP_EXPR in GIMPLE.
As the docs say, LOOP_EXPRS are no longer GIMPLE, they are lowered to
explicit gotos.
