Commit Message
I noticed in test-case gdb.reverse/map-to-same-line.exp, that the end of main:
...
00000000004102c4 <end_of_sequence>:
4102c4: 52800000 mov w0, #0x0 // #0
4102c8: 9100c3ff add sp, sp, #0x30
4102cc: d65f03c0 ret
...
is not described by the line table:
...
File name Line number Starting address View Stmt
...
map-to-same-line.c 54 0x4102ac x
map-to-same-line.c - 0x4102c4
...
Fix this by ending the line table at $main_end.
Likewise in a few other test-cases, found using:
...
$ find gdb/testsuite/ -type f \
| xargs grep -B1 DW_LNE_end_sequence \
| grep set_address \
| egrep -v "_end|_len"
...
Tested on aarch64-linux.

Tom:
I am seeing a regression on Power 10 with this patch. Specifically the change to file dw2-lines.exp.
--- a/gdb/testsuite/gdb.dwarf2/dw2-lines.exp
+++ b/gdb/testsuite/gdb.dwarf2/dw2-lines.exp
@@ -104,7 +104,7 @@ proc test_1 { _cv _cdw64 _lv _ldw64 {_string_form ""}} {

+ DW_LNE_set_address "$main_start + $main_len"

}
The change results in the test failing on PowerPC.

If I edit the file and change the line back to bar_label_5 the test passes. I am only seeing an issue with the change to in this file. I specifically tested dw2-inline-header-2.exp and the change seems to work just fine there. I am really puzzled as to why it doesn't work in file dw2-lines.exp.
I put the print statement in:
puts "CARLL, main_start = $main_start, main_len = $main_len"
DW_LNE_set_address "$main_start + $main_len"
I get
CARLL, main_start = main_label - 28, main_len = 76
I tried printing main_label but it doesn't seem to be defined.
ERROR: in testcase /../binutils-gdb-current/gdb/testsuite/gdb.dwarf2/dw2-lines.exp
ERROR: can't read "main_label": no such variable
ERROR: tcl error code TCL LOOKUP VARNAME main_label
ERROR: tcl error info:
can't read "main_label": no such variable
I was hoping to be able to verify that bar_label_5 and "$main_start + $main_len" are the same but no luck.
Anyway, any thoughts as to why this is failing on PowerPC? I assume it works fine on X86.
At the moment, I am a little puzzled as to what the right fix is.

Tom:
I think I see the issue. bar_label_5 is a label in function bar. But "$main_start + $main_len" this
will give us an address in main, not bar. So, we need to set the address relative to the beginning of function bar?

Tom:
The following patch fixes the issue for me on PowerPC. Please let me know if it looks ok and if the patch works on your systems as well. Thanks.

----------------------------------------------------------------------
Fix end_sequence addresses for dw2-lines.exp
The patch:
From f0d556d14b1d1c3f8e2f9c13b08adca22e1b8c9c Mon Sep 17 00:00:00 2001
From: Tom de Vries <tdevries@suse.de>
Date: Wed, 17 Apr 2024 12:55:00 +0200
Subject: [PATCH] [gdb/testsuite] Fix end_sequence addresses
I noticed in test-case gdb.reverse/map-to-same-line.exp, that the end of main:
...
00000000004102c4 <end_of_sequence>:
4102c4: 52800000 mov w0, #0x0 // #0
4102c8: 9100c3ff add sp, sp, #0x30
4102cc: d65f03c0 ret
...
is not described by the line table:
...
File name Line number Starting address View Stmt
...
map-to-same-line.c 54 0x4102ac x
map-to-same-line.c - 0x4102c4
...
Fix this by ending the line table at $main_end.
Likewise in a few other test-cases, found using:
...
$ find gdb/testsuite/ -type f \
| xargs grep -B1 DW_LNE_end_sequence \
| grep set_address \
| egrep -v "_end|_len"
...
Tested on aarch64-linux.

The issue in file dw2-lines.exp is the change

The label bar_label_5 is in function bar, not function main. The new
set address should have been $bar_start + $bar_len.

Hi Carl,
I don't see the FAILs you mentioned, but your patch is correct, and
doesn't regress the test-case for me on x86_64-linux.
Thanks for finding, reporting and fixing this.
So, approved, but consider making the commit message shorter.
Including the entire commit message of the patch you're fixing is a bit
of an overkill.
Approved-By: Tom de Vries <tdevries@suse.de>

Tom:
Thanks for verifying the patch on X86. I agree, including the entire commit message from your patch
is a little overkill. I cut down your commit message and made the description of my fix a little better.
Here is what I now have for the commit message:
------------------------------------------------------
Fix end_sequence addresses for dw2-lines.exp
The patch:
From f0d556d14b1d1c3f8e2f9c13b08adca22e1b8c9c Mon Sep 17 00:00:00 2001

Subject: [PATCH] [gdb/testsuite] Fix end_sequence addresses
I noticed in test-case gdb.reverse/map-to-same-line.exp, that the end of main:
...
00000000004102c4 <end_of_sequence>:
4102c4: 52800000 mov w0, #0x0 // #0

4102cc: d65f03c0 ret
...
is not described by the line table:
...
<snip>
The regression failure on PowerPC is due to the change in file
dw2-lines.exp,
- DW_LNE_set_address bar_label_5
+ DW_LNE_set_address "$main_start + $main_len"
The label bar_label_5 is in function bar, not function main. The new
set address should have been $bar_start + $bar_len.
--------------------------------------------------------
Please let me know if that looks reasonable and I will then commit the fix. Thanks!
