Function Documentation

◆ gate_lto_out()

bool gate_lto_out ( void )
Gate function for all LTO streaming passes.   

References seen_error().

◆ lto_check_version()

void lto_check_version ( int major,
int minor,
const char * file_name )
Check that the version MAJOR.MINOR is the correct version number.   

References fatal_error(), input_location, LTO_major_version, and LTO_minor_version.

◆ lto_get_section_name()

char * lto_get_section_name ( int section_type,
const char * name,
int node_order,
struct lto_file_decl_data * f )
Get a section name for a particular type or name.  The NAME field
is only used if SECTION_TYPE is LTO_section_function_body. For all
others it is ignored.  The callee of this function is responsible
to free the returned name.

◆ lto_streamer_hooks_init()

◆ lto_streamer_init()

void lto_streamer_init ( void )
Initialization common to the LTO reader and writer.   

References streamer_check_handled_ts_structures().

Referenced by lto_output(), and lto_reader_init().

◆ lto_tag_name()

◆ print_lto_report()

Variable Documentation

◆ lto_stats

struct lto_stats_d lto_stats
Miscellaneous utilities for GIMPLE streaming.  Things that are used
   in both input and output are here.

◆ lto_stream_offload_p

◆ section_name_prefix

const char* section_name_prefix = LTO_SECTION_NAME_PREFIX
Can be either OFFLOAD_SECTION_NAME_PREFIX when we stream IR for offload
compiler, or LTO_SECTION_NAME_PREFIX for LTO case.
