Bugs reported after the release of 3.8.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This file lists bugs that were reported after 3.8.0 was released, both
in 3.8.0 and trunk, and that have not been closed.  Bugs that have
been closed as "fixed" are listed in the top level NEWS file instead.
In other words they get listed here first and moved to NEWS if they
get fixed.

This file also tracks commits & fixes that should be pushed to the 3.8
branch.

-------- Bugs brought forward from 3_7_BUGSTATUS.txt --------

291310  FXSAVE instruction marks memory as undefined on amd64
  x86 vs amd64 inconsistency?
  **is fixed in 3.8.0, but was not marked as such
  ** no it's not; v38BRANCH shows error, vTRUNK doesn't -- investigate

303536  ioctl for SIOCETHTOOL (ethtool(8)) isn't wrapped (w/ patch)
  we should fix this

-------- Unfixed in 3.8.0

303741  sockaddr* parameter of recvfrom not handled correctly
        (corruption not detected later on)
  QUERIED -- need test case, looks easy to fix

303877  valgrind doesn't support compressed debuginfo sections.

304259  support Darwin 12 (Mac OS 10.8, Mountain Lion)
  Canonical OSX 10.8

304321  m_signals.c:2314 (sync_signalhandler_from_kernel): Assertion 'tid != 0' failed
  Probably invalid (way too old)

304450  time logging tools ?
  wishlist

304675  make install-strip fails when cross-compiling
  w/ patch; but needs checking (should be more general?  assumes auto*
  version?)

304676  regtest hangs on mac OS X (mchelp, coolo_sigaction, system)
  probably related to 301281 et al
  QUERIED

304832  ppc32: build failure
  probably invalid

305170  linux: add FIOCLEX and FIONCLEX ioctls
  w/ patch, looks pretty harmless

305431  Use find_buildid shdr fallback for separate .debug files

n-i-bz  exp-sgcheck asserts on gcc-4.6.2 generated Dwarf3

305728  Add support for AVX2 instructions

305957  m_debuginfo/d3basics.c:965 (vgModuleLocal_evaluate_GX):
        Assertion 'aMin == (Addr)0' failed.
        QUERIED -- no info so far

306004  Wishlist: port valgrind to sparc

306035  s390x: Fix IR generation for LAAG and friends

306098  s390x: alternate opcode form for convert to/from fixed
