Bug ID: 95601
Summary: Remove workaround for GDB PR in
pass_partition_blocks::gate
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
Current GCC contains this workaround in bb-reorder.c:
...
/* Workaround a bug in GDB where read_partial_die doesn't cope
with DIEs with DW_AT_ranges, see PR81115. */
&& !(in_lto_p && MAIN_NAME_P (DECL_NAME (fun->decl))));
...
The PR81115 is a typo, it actually refers to gcc PR 81155, as we can see from
the log message:
...
commit 8f72ce2cec8b8961f381995eb6e2c5de1cd0f3d3

re PR debug/81155 (Debug make check regressions in GCC 8.0)
PR debug/81155
* bb-reorder.c (pass_partition_blocks::gate): In lto don't
partition
main to workaround a bug in GDB.
From-SVN: r256592
...
The PR81155 discusses a GDB bug, but no GDB counterpart was filed, so I've
filed https://sourceware.org/bugzilla/show_bug.cgi?id=26095 for this purpose.
The GDB PR may be a duplicate of
https://sourceware.org/bugzilla/show_bug.cgi?id=23331 , in which case this
should be fixed from gdb release 9.1 onwards.
So, on the GCC side we need to test whether indeed the workaround is no longer
required for a recent gdb, and if so, either remove the workaround, or add a
comment to the workaround about starting which gdb release the workaround is no
longer required.
