Hi there,
this is second iteration of my .debug_line support for dwarf.exp DWARF
assembler. Last time around I implemented it as a macro, and the
request was to make it a first-class section. This is now implemented.
As before, only minimal support for include and file name lists is
added, so that DW_AT_decl_file references elsewhere in DWARF file work.
Thoughts?
Thanks,
Petr

build_id 0102030405060708
declare_labels L;

DW_TAG_compile_unit {

Hi.
Just one nit.
Otherwise LGTM.

Should this be:
if { "$label" != "" } {
_emit "$label:"
}
?

No, it's calling the function named "$label:". To define the label that
the user supplied. Would this make it clearer?

Yep, that helps in not introducing regressions :) But you never know.

Makes sense. I'll try to figure out how to put this together and get

Yeah, it is useful to GDB.

Is there any reason you decide to implement this attribute as a macro
attribute? DW_AT_stmt_list attribute itself is quite simple, whose
value is a section offset to the .debug_line section, so we don't need
to bother macro attribute, which doesn't exist in dwarf spec but are
used to generate some dwarf attributes.
I'd like DW_AT_stmt_list implemented in the same way as other
attributes, for example,
cu {is_64 0 version 4 addr_size 8} {
compile_unit {
{ stmt_list $label1 sec_offset}
}
...
label1: line_number_info {
line_number_program_header {
}
line_number_program {
}
}
}
what do you think?

Why don't you apply for an account for you? It is easy to do so

be the people to approve your request.

This part looks right to me, and DW_FORM_sec_offset can be used by
other attributes too, such as DW_AT_ranges.

Hello,
this is half ping, half V2 of the patch that I sent last week. I fixed
a bug in generating the header since V1.
This is what I wrote last week, and it all still holds:
like GDB itself, dwgrep uses dwarf.exp to fabricate Dwarfs for its test
cases. For one test case, I need to create a stub .debug_line section
and reference files defined therein from DW_AT_decl_file. Hence this
patch, which implements generating barest minimum of .debug_line.
I suspect this could be useful for GDB as well, git grep showed me some
.exp's creating .debug_line by hand, but I didn't really take a close
look.
There were no regressions on x86_64.
Example of use:
Dwarf::assemble "foo.s" {
build_id 0102030405060708
cu {is_64 0 version 4 addr_size 8} {
DW_TAG_compile_unit {
{MACRO_AT_stmt_list {
{include "foo"}
{file_name "foo.c" 1}
}}
} {
DW_TAG_subprogram {
# We can now reference the source file.
{DW_AT_decl_file 1 DW_FORM_data1}
}
}
}
}
I do not have commit rights, so if this patch is acceptable, I will need
someone to commit this for me.
Let me know what you think.
Thanks,
