Add a 3_14_BUGSTATUS.txt file and add to it all bugs reported since 3.14 was release.

At least, the bugs are post-triaged ones, so some have been removed.

========================================================================
========================================================================
Created Sat 9 Mar 2019. This contains bugs reported only after the release of
3.14.0. Unlike in 3_13_BUGSTATUS.txt and perhaps earlier such files, it
doesn't carry over bugs from earlier versions.
========================================================================

=== Debuginfo reader ===================================================
404843 s390x: backtrace sometimes ends prematurely
Should try to fix for 3.15.0
405295 valgrind 3.14.0 dies due to mysterious DWARF information? (output from
rust used by Mozilla TB.)
But possibly only when --read-var-info=yes

=== Tools/Callgrind ====================================================
399355 Add callgrind_diff
Has patch
400234 keep the parameters of the most costly path
Wishlist
=== Tools/DHAT =========================================================
=== Tools/DRD ==========================================================
=== Tools/Helgrind =====================================================
400793 pthread_rwlock_timedwrlock false positive
Probably would be easy to fix, but requires testing
405205 tests/filter_libc: remove the line holding the futex syscall error
entirely
Is maybe related to Helgrind tests? Is unclear

398569 invalid reads reported in libarmmem memcmp when using strings
8 byte p-l-ok thing on arm32
401284 False positive "Source and destination overlap in strncat"
possibly valid; possible off-by-one error in overlap checking?
402604 Report All Dangling pointers upon exit and monitor command
Wishlist
402833 memcheck/tests/overlap testcase fails, memcpy seen as memmove
Probably not easy to fix
403802 leak_cpp_interior fails with some reachable blocks different than
expected
Leak-count numbers differ?
405201 Incorrect size of struct vki_siginfo on 64-bit Linux architectures

400162 Patch: Guard against __GLIBC_PREREQ for musl libc
Looks like simple fix; should take
400164 helgrind test encounters mips x-compiler warnings and assembler error
Obscure compiler?
401742 unreproducible .a files should not be built with LTO
Some LTO wierdness; doesn't seem terribly important
402123 invalid assembler opcodes for mips32r2
402351 mips64 libvexmultiarch_test fails on s390x
404888 [PATCH] autotools cleanup series
Should try to land for 3.15.0

Should try to land for 3.15.0
=== Uncategorised/run ==================================================
400119 Library search path in Valgrind/ldd
400807 --error-exitcode still sends the wrong value
Probable not-a-bug

=== VEX/amd64 ==========================================================
398183 Vex errors with _mm256_shuffle_epi8/vpshufb
Potentially serious?

400538 vex amd64->IR: 0x48 0xCF 0xF 0x1F 0x0 0xFF 0xD2 0xCC 0x90 0x55
Should fix (Wine/Windows)
400829 unhandled instruction bytes in macOS
Seems like CMOVNS; and therefore I think this is fishy
404272 vex amd64->IR: 0x66 0xF 0x38 0x23 0xC0 0xF3 (PMOVSXWD)
Should fix
=== VEX/arm32 ==========================================================
401072 More than 1000 errors on TegraK1 L4T 3.14 glibc 2.23 (Custom yocto
system)
I suspect some kind of stm-as-push problem; the usual thing

400593 In Coregrind, use statx for some internal syscalls if [f]stat[64] fail
Part of "support for nanoMIPS" ?
400872 Add nanoMIPS support to Valgrind
Looks big and complex. No communication re reviewing?

I'm unclear what this signifies
