4Subject: [PATCH 1/4] valgrind-monitor.py regular expressions should use raw
5 strings
6
7With python 3.12 gdb will produce the following SyntaxWarning when
8loading valgrind-monitor-def.py:
9
10 /usr/share/gdb/auto-load/valgrind-monitor-def.py:214:
11 SyntaxWarning: invalid escape sequence '\['
12 if re.fullmatch("^0x[0123456789ABCDEFabcdef]+\[[^\[\]]+\]$", arg_str):
13
14In a future python version this will become an SyntaxError.
15
16Use a raw strings for the regular expression.

4Subject: [PATCH 4/4] Bug 478624 - Valgrind incompatibility with binutils-2.42
5 on x86 with new nop patterns (unhandled instruction bytes: 0x2E 0x8D 0xB4
6 0x26)
7
8It was a bit of a struggle to get the testcase to build
9with both clang and gcc (oddly enough gcc was more difficult) so
10I just resorted to using .byte arrays.
11
12(cherry picked from commit d35005cef8ad8207542738812705ceabf137d7e0)
13
14Upstream-Status: Backport [https://sourceware.org/git/?p=valgrind.git;a=commit;h=41ff9aa49f6c54c66d0e6b37f265fd9cb0176057]
