3 * collect2.c (DO_COLLECT_EXPORT_LIST): New internal macro,
4 always defined. Reflect definition or absence of such for
5 COLLECT_EXPORT_LIST. Readability helper.
6 (scanfilter): New enum, to help control what symbols
7 are to be considered or ignored by scan_prog_file.
8 (enum pass): Rename as "scanpass", moved together with scanfilter
9 prior to scan_prog_file's prototype.
10 (scan_prog_file): Accept and honor scanpass and scanfilter arguments.
11 Group prototype with the scanpass/scanfilter definitions, factorize
12 head comments for the several implementations at the prototype.
13 (main): Reorganize the first pass link control to let AIX
14 drag only the needed frame tables in executables. Prevent
15 frame tables collection during the scan aimed at static ctors.
16 Pre-link and scan for frame tables later to compensate.
17 * doc/tm.texi (ASM_OUTPUT_DWARF_TABLE_REF): New macro.
18 A C statement to issue assembly directives that create a reference
19 to the given DWARF table identifier label from the current function
20 section.
21 * dwarf2out.c (switch_to_eh_frame_section): Add a BACK argument
22 to differentiate first time section entry. Only emit a .data
23 tables start identifier label the first time around.
24 (switch_to_frame_table_section): New function. Helper for
25 output_call_frame_info to switch possibly BACK into the eh_frame
26 or the debug_frame section depending on FOR_EH.
27 (output_call_frame_info): Use helper to first enter the proper
28 frame section.
29 (output_fde): Use ASM_OUTPUT_DWARF_TABLE_REF when defined to
30 emit a link to the frame table start label from each function
31 section.
32 * config/rs6000/rs6000.c (rs6000_aix_asm_output_dwarf_table_ref):
33 New function. Implementation of ASM_OUTPUT_DWARF_TABLE_REF.
34 * config/rs6000/rs6000-protos.h: Declare it.
35 * config/rs6000/aix.h (ASM_OUTPUT_DWARF_TABLE_REF): Define.
