Function Documentation

is_va_list_type()

bool is_va_list_type ( tree type )

inline

Return true iff TYPE is stdarg va_list type (which early SRA and IPA-SRA
should leave alone).

sra_get_max_scalarization_size()

unsigned HOST_WIDE_INT sra_get_max_scalarization_size

(

void

)

Get the total total scalarization size limit in the current function.

sra_total_scalarization_would_copy_same_data_p()

bool sra_total_scalarization_would_copy_same_data_p	(	tree	t1,
		tree	t2 )

Given two types in an assignment, return true either if any one cannot be
totally scalarized or if they have padding (i.e. not copied bits)

type_internals_preclude_sra_p()

bool type_internals_preclude_sra_p	(	tree	type,
		const char **	msg )

Scalar Replacement of Aggregates (SRA) converts some structure
   references into scalar references, exposing them to the scalar
   optimizers.
