Function Documentation

rtx alloc_EXPR_LIST ( )

This call is used in place of a gen_rtx_EXPR_LIST. If there is a cached node available, we'll use it, otherwise a call to gen_rtx_EXPR_LIST is made.

Referenced by find_constant_src().

rtx alloc_INSN_LIST ( )

This call is used in place of a gen_rtx_INSN_LIST. If there is a cached node available, we'll use it, otherwise a call to gen_rtx_INSN_LIST is made.

Referenced by find_constant_src(), free_INSN_LIST_list(), and one_code_hoisting_pass().

rtx concat_INSN_LIST ( )

Duplicate the INSN_LIST elements of COPY and prepend them to OLD.

References unused_expr_list, and XEXP.

rtx copy_INSN_LIST ( )

Make a copy of the INSN_LIST list LINK and return it.

static rtx* find_list_elem ( )
static

Find corresponding to ELEM node in the list pointed to by LISTP. This node must exist in the list. Returns pointer to that node.

References XEXP.

void free_EXPR_LIST_list ( )

This function will free up an entire list of EXPR_LIST nodes.

void free_EXPR_LIST_node ( )

This function will free up an individual EXPR_LIST node.

References free_INSN_LIST_node(), and remove_list_elem().

Referenced by df_word_lr_top_dump().

void free_INSN_LIST_list ( )

This function will free up an entire list of INSN_LIST nodes.

References alloc_INSN_LIST(), NULL, and XEXP.

void free_INSN_LIST_node ( )

This function will free up an individual INSN_LIST node.

References remove_list_node(), and XEXP.

static void free_list ( )
static

This function will free an entire list of either EXPR_LIST, INSN_LIST or DEPS_LIST nodes. This is to be used only on lists that consist exclusively of nodes of one type only. This is only called by free_EXPR_LIST_list, free_INSN_LIST_list and free_DEPS_LIST_list.

rtx remove_free_EXPR_LIST_node ( )

Remove and free the first node in the EXPR_LIST pointed to by LISTP.

void remove_free_INSN_LIST_elem ( )

Remove and free corresponding to ELEM node in the INSN_LIST pointed to by LISTP.

References XEXP.

rtx remove_free_INSN_LIST_node ( )

Remove and free the first node in the INSN_LIST pointed to by LISTP.

rtx remove_list_elem ( )

Removes corresponding to ELEM node from the list pointed to by LISTP. Returns that node.

Referenced by free_EXPR_LIST_node().

static void remove_list_node ( )
static

Remove the node pointed to by LISTP from the list.

Referenced by free_INSN_LIST_node().


Variable Documentation
