Release 3.17.0 (18 Mar 2021)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3.17.0 is a feature release with many improvements and the usual collection
of bug fixes.
3.17.0 is a primarily a bug-fix release.
This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,

* ==================== CORE CHANGES ===================
* DWARF version 5 support
* DWARF version 5 support. Valgrind can now read DWARF version 5 debuginfo as
produced by GCC 11.
- Valgrind can now read DWARF version 5 debuginfo as produced by GCC 11
* Valgrind now supports debuginfod, an HTTP server for distributing ELF/DWARF
debugging information. When a debuginfo file cannot be found locally,
Valgrind is able to query debuginfod servers for the file using its
build-id. See the user manual for more information about debuginfod support.
* ================== PLATFORM CHANGES =================
* arm64:
- Inaccuracies resulting from double-rounding in the simulation of
floating-point multiply-add/subtract instructions have been fixed. These
should now behave exactly as the hardware does.
- Partial support for the ARM v8.2 instruction set. v8.2 support work is
ongoing. Support for the half-word variants of at least the following
instructions has been added:
FABS <Hd>, <Hn>
FABS <Vd>.<T>, <Vn>.<T>
FNEG <Hd>, <Hn>
FNEG <Vd>.<T>, <Vn>.<T>
FSQRT <Hd>, <Hn>
FSQRT <Vd>.<T>, <Vn>.<T>

* s390:
- Implement the new instructions/features that were added to
z/Architecture with the vector-enhancements facility 1. Also
cover the instructions from the vector-packed-decimal facility
that are defined outside the chapter "Vector Decimal
Instructions", but not the ones from that chapter itself.

Since the miscellaneous instruction extensions facility 2 was
already added in Valgrind 3.16.0, this completes the support
necessary to run general programs built with `--march=z14' under
Valgrind. The vector-packed-decimal facility is currently not
exploited by the standard toolchain and libraries.

mask instructions, bfloat16 GER instructions, and bfloat16 to/from float
32-bit conversion instructions are still missing.

* ==================== TOOL CHANGES ====================
* General tool changes
- All the tools and their vgpreload libraries are now installed under
libexec because they cannot be executed directly and should be run
through the valgrind executable. This should be an internal, not user
visible, change, but might impact valgrind packagers.

- The --track-fds option now respects -q, --quiet and won't output
anything if no file descriptors are leaked. It also won't report
the standard stdin (0), stdout (1) or stderr (2) descriptors as
being leaked with --trace-fds=yes anymore. To track whether the
standard file descriptors are still open at the end of the program
run use --trace-fds=all.
