* Many bugfixes, too many to list here, see NEWS file
- The implicit memcpy done by each call to realloc now counts towards the
read and write counts of resized heap blocks, making those counts higher
and more accurate.
- cg_annotate's --auto and --show-percs options now default to 'yes', because
they are usually wanted.
- callgrind_annotate's --auto and --show-percs options now default to 'yes',
because they are usually wanted.
- The command option --collect-systime has been enhanced to specify
the unit used to record the elapsed time spent during system calls.
The command option now accepts the values no|yes|msec|usec|nsec,
where yes is a synonym of msec. When giving the value nsec, the
system cpu time of system calls is also recorded.
- Several memcheck options are now dynamically changeable.
Use valgrind --help-dyn-options to list them.
- The release 3.15 introduced a backward incompatible change for
some suppression entries related to preadv and pwritev syscalls.
When reading a suppression entry using the unsupported 3.14 format,
valgrind will now produce a warning to say the suppression entry will not
work, and suggest the needed change.
- Significantly fewer false positive errors on optimised code generated by
Clang and GCC. In particular, Memcheck now deals better with the
situation where the compiler will transform C-level "A && B" into "B && A"
under certain circumstances (in which the transformation is valid).
Handling of integer equality/non-equality checks on partially defined
values is also improved on some architectures.
- The exprimental Stack and Global Array Checking tool has been removed.
It only ever worked on x86 and amd64, and even on those it had a
high false positive rate and was slow. An alternative for detecting

Subject: [PATCH] Power PC Fix extraction of the L field for sync instruction
|
|
|
|
The L field is currently a two bit[22:21] field in ISA 3.0. The size of the
|
|
L field has changed over time.
|
|
|
|
Currently the ISA 3.0 Valgrind sync instruction support code sets the
|
|
flag_L for the instruction L field to a five bit value that includes bits
|
|
that are marked reserved the sync instruction. This patch fixes the issue for ISA 3.0
|
|
to only setting flag_L the specified two bits.
