Function Documentation

◆ ggc_free()

void ggc_free ( void * p )

Free a block.  To be used when known for certain it's not reachable.

References free().

◆ ggc_grow()

void ggc_grow ( void )

Assume that all GGC memory is reachable and grow the limits for next collection.

Referenced by ipa_read_optimization_summaries_1(), and ipa_read_summaries_1().

◆ ggc_internal_alloc()

void * ggc_internal_alloc	(	size_t	size,
		void(*	f )(void *),
		size_t	,
		size_t	CXX_MEM_STAT_INFO )

Allocation.

The internal primitive.

◆ ggc_internal_cleared_alloc()

void * ggc_internal_cleared_alloc	(	size_t	size,
		void(*	f )(void *),
		size_t	,
		size_t	MEM_STAT_DECL )

Allocates cleared memory.

This version is used by the gen* programs and certain language-specific
targets (such as java), where we don't really need GC at all.
This prevents problems with pulling in all the tree stuff.

For a given size of memory requested for allocation, return the
actual size that is going to be allocated.

◆ ggc_trim()

void ggc_trim ( void )

Return unused memory pages to the system.
