Function Documentation

◆ clone_function_name() [1/3]

tree clone_function_name	(	const char *	name,
		const char *	suffix,
		unsigned long	number )

Return a new assembler name for a clone of decl named NAME.  Apart
from the string SUFFIX, the new name will end with the specified
NUMBER.  If clone numbering is not needed then the two argument
clone_function_name should be used instead.

References ASM_FORMAT_PRIVATE_NAME, get_identifier(), ggc_alloc(), and symbol_table::symbol_suffix_separator().

◆ clone_function_name() [2/3]

tree clone_function_name	(	tree	decl,
		const char *	suffix )

Return a new assembler name ending with the string SUFFIX for a
clone of DECL.

References DECL_ASSEMBLER_NAME, get_identifier(), ggc_alloc(), IDENTIFIER_POINTER, and symbol_table::symbol_suffix_separator().

◆ clone_function_name() [3/3]

tree clone_function_name	(	tree	decl,
		const char *	suffix,
		unsigned long	number )

Return a new assembler name for a clone of DECL.  Apart from the
string SUFFIX, the new name will end with the specified NUMBER.  If
clone numbering is not needed then the two argument
clone_function_name should be used instead.

◆ clone_function_name_numbered() [1/2]

tree clone_function_name_numbered	(	const char *	name,
		const char *	suffix )

Return a new assembler name for a clone of decl named NAME.  Apart
from the string SUFFIX, the new name will end with a unique (for
each NAME) unspecified number.  If clone numbering is not needed
then the two argument clone_function_name should be used instead.
Should not be called directly except for by
lto-partition.cc:privatize_symbol_name_1.

◆ clone_function_name_numbered() [2/2]

tree clone_function_name_numbered	(	tree	decl,
		const char *	suffix )

Return a new assembler name for a clone of DECL.  Apart from string
SUFFIX, the new name will end with a unique (for each DECL
assembler name) unspecified number.  If clone numbering is not
needed then the two argument clone_function_name should be used
instead.

◆ duplicate_thunk_for_node()

static cgraph_node * duplicate_thunk_for_node	(	cgraph_node *	thunk,
		cgraph_node *	node )

static

Duplicate thunk THUNK if necessary but make it to refer to NODE.
ARGS_TO_SKIP, if non-NULL, determines which parameters should be omitted.
Function can return NODE if no thunk is necessary, which can happen when
thunk is this_adjusting but we are removing this parameter.

◆ set_new_clone_decl_and_node_flags()

static void set_new_clone_decl_and_node_flags ( cgraph_node * new_node )

static

Set flags of NEW_NODE and its decl.  NEW_NODE is a newly created private
clone or its thunk.

◆ update_call_expr()

static void update_call_expr ( cgraph_node * new_version )

static

The edges representing the callers of the NEW_VERSION node were
fixed by cgraph_function_versioning (), now the call_expr in their
respective tree code should be updated to call the NEW_VERSION.
