LDC debug output
Jason House wrote (Thu, 06 Aug 2009 07:55:55 -0400):
No luck with gdb. Here's something interesting though:
$ dmd2/linux/bin/dmd -g main.d -ofmain
$ objdump -g main > info.dmd
objdump: Warning: .debug_info offset of 0x12c in .debug_pubnames section
does not point to a CU header.
$ ldc-0.9.1-x86_32/bin/ldc -g main.d
$ objdump -g main > info.ldc
objdump: Warning: Bogus end-of-siblings marker detected at offset 226
in .debug_info section
objdump: Warning: Bogus end-of-siblings marker detected at offset 227
in .debug_info section
objdump: Warning: Bogus end-of-siblings marker detected at offset 228
in .debug_info section
objdump: Warning: Further warnings about bogus end-of-sibling markers
suppressed
When comparing the output, I do see that ldc outputs dw_at_subprogram
when dmd outputs dw_at_module. I think it's safe to ignore that ldc
outputs _D4main16__moduleinfoCtorZ and dmd does not.
I see this in the ldc output but not dmd:
DW_AT_MIPS_linkage_name DW_FORM_string
DW_AT_decl_file DW_FORM_data1
DW_AT_decl_line DW_FORM_data1
DW_AT_low_pc DW_FORM_addr
DW_AT_high_pc DW_FORM_addr
DW_AT_frame_base DW_FORM_block1
I also see
DW_AT_decl_line DW_FORM_data1 (in ldc)
DW_AT_decl_line DW_FORM_data2 (in dmd)
There's a few other differences, but I nievely thing they're either
trivial or related to the above. LDC outputs a few "identical" tags in
a slightly different order. I can provide details on that if it'd help.

As of Thu, 29 Apr 2010 14:45:37 +0000, the D patches have been approved and
pushed upstream!
http://sourceware.org/git/?p=gdb.git;a=commit;h=870850ddab624f9d0111a4a0733cf7f5edf9bf91
This means gdb 7.2 and above will have D support built in =)
The current patch does demangling and makes sure strings are handled correctly,
it does not add support for D extensions (so compiling with -gc is still
required for now).

I (happily) think that this bug can be closed now, and since I opened it, I
will :).
Any other thing that needs tracking about improving the D support in GDB (like
supporting the D extensions) can be done in another bug report.
