# --smc-check=all-non-file is required to deal with code generation and
# patching by the various JITS. Note that this is only necessary on
# x86 and x86_64, but not on ARM. This flag is only necessary for
# Valgrind versions prior to 3.11.
#
# --vex-iropt-register-updates=allregs-at-mem-access is required so that
# Valgrind generates correct register values whenever there is a
# segfault that is caught and handled. In particular OdinMonkey
# requires this. More recent Valgrinds (3.11 and later) provide
# --px-default=allregs-at-mem-access and
# --px-file-backed=unwindregs-at-mem-access
# which provide a significantly cheaper alternative, by restricting the
# precise exception behaviour to JIT generated code only.
#
# --trace-children=yes is required to get Valgrind to follow into
# content and other child processes. The resulting output can be
# difficult to make sense of, and --child-silent-after-fork=yes
# helps by causing Valgrind to be silent for the child in the period
# after fork() but before its subsequent exec().
#
# --trace-children-skip lists processes that we are not interested
# in tracing into.
#
# --leak-check=full requests full stack traces for all leaked blocks
# detected at process exit.
#
# --show-possibly-lost=no requests blocks for which only an interior
# pointer was found to be considered not leaked.

A class for handling Valgrind output.
Valgrind errors look like this:
==60741== 40 (24 direct, 16 indirect) bytes in 1 blocks are definitely lost in loss record 2,746 of 5,235
==60741== at 0x4C26B43: calloc (vg_replace_malloc.c:593)
==60741== by 0x63AEF65: PR_Calloc (prmem.c:443)

==60741== by 0xA042443: ffi_call (ffi64.c:485)
For each such error, this class extracts most or all of the first (error
kind) line, plus the function name in each of the first few stack entries.
With this data it constructs and prints a TEST-UNEXPECTED-FAIL message that
TBPL will highlight.
It buffers these lines from which text is extracted so that the
TEST-UNEXPECTED-FAIL message can be printed before the full error.
Parsing the Valgrind output isn't ideal, and it may break in the future if
Valgrind changes the format of the messages, or introduces new error kinds.
To protect against this, we also count how many lines containing
"<insert_a_suppression_name_here>" are seen. Thanks to the use of
--gen-suppressions=yes, exactly one of these lines is present per error. If
the count of these lines doesn't match the error count found during
parsing, then the parsing has missed one or more errors and we can fail
appropriately.
