Subject: [PATCH 1/2 ver 2] Fix reverse stepping multiple contiguous PC ranges over the line table.
Date: Fri, 23 Jun 2023 13:04:36 -0700 [thread overview]
Message-ID: <86caeaa0e3fc77026118531562832aa622621db8.camel@us.ibm.com> (raw)
In-Reply-To: <4ab1e3ff-eede-5573-f58f-63ff8b1e23bb@simark.ca>
Simon, GDB maintainers:
Version 2, updated the compiler check and handling for gcc version 6
and earlier. Retested on Power 10.
Per the comments on version 4 for the gdb.reverse/func-map-to-same-
line.exp, I have added support to proc gdb_compile to enable or disable
generating line information as part of the debug information. The two
new options are column-info and no-column-info.
This patch implements the new options for gdb_compile.
These options have been tested with patch 2 of 2 on PowerPC with the
GCC and clang compilers.
Please let me know if the patch is acceptable for mainline. Thanks.
Carl
-----------------------------
Add gdb_compile options column-info and no-column-info
This patch adds two new options to gdb_compile to specify if the compile
should or should not generate the line table information. The
options are supported on clang and gcc version 7 and newer.
Patch has been tested on PowerPC with both gcc and clang.
