1575a795cb Add missing mode in open(2) calls with O_CREAT.
When O_CREAT is specified, the third, variadic argument is
required as the permission. If on is not passed, then depending
on the ABI, either the contents of the third argument register
or some arbitrary stuff on the stack will be used as the permission.

This has been merged to NetBSD.

a74dca96a1 Fix two mismatches between function declaration and definition.
In both cases, function pointer arguments were inconsistently declared
and the result worked because of C's odd rules around function pointer
(de)references.  With a stricter compiler these fail to compile.

f7e8f5d439 Pull in r365760 from upstream lld trunk (by Fangrui Song):
[ELF] Handle non-glob patterns before glob patterns in version
  scripts & fix a corner case of --dynamic-list

  This fixes PR38549, which is silently accepted by ld.bfd.
  This seems correct because it makes sense to let non-glob patterns
  take precedence over glob patterns.

  lld issues an error because
  `assignWildcardVersion(ver, VER_NDX_LOCAL);` is processed before
  `assignExactVersion(ver, v.id, v.name);`.

  Move all assignWildcardVersion() calls after assignExactVersion()
  calls to fix this.

  Also, move handleDynamicList() to the bottom. computeBinding() called
  by includeInDynsym() has this cryptic rule:

      if (versionId == VER_NDX_LOCAL && isDefined() && !isPreemptible)
	return STB_LOCAL;

  Before the change:

  * foo's version is set to VER_NDX_LOCAL due to `local: *`
  * handleDynamicList() is called
    - foo.computeBinding() is STB_LOCAL
    - foo.includeInDynsym() is false
    - foo.isPreemptible is not set (wrong)
  * foo's version is set to V1

  After the change:

  * foo's version is set to VER_NDX_LOCAL due to `local: *`
  * foo's version is set to V1
  * handleDynamicList() is called
    - foo.computeBinding() is STB_GLOBAL
    - foo.includeInDynsym() is true
    - foo.isPreemptible is set (correct)

128c495e50 Apply a workaround to be able to build clang 8.0.0 headers with clang
3.4.1, which is still in the stable/10 branch.

It looks like clang 3.4.1 implements static_asserts by instantiating a
temporary static object, and if those are in an anonymous union, it
results in "error: anonymous union can only contain non-static data
members".

To work around this implementation limitation, move the static_asserts
in question out of the anonymous unions.

This should make building the latest stable/11 from stable/10 possible
again.

  [IndVarSimplify] Fixup nowrap flags during LFTR (PR31181)

  Fix for https://bugs.llvm.org/show_bug.cgi?id=31181 and partial fix
  for LFTR poison handling issues in general.

  When LFTR moves a condition from pre-inc to post-inc, it may now
  depend on value that is poison due to nowrap flags. To avoid this, we
  clear any nowrap flag that SCEV cannot prove for the post-inc addrec.

  Additionally, LFTR may switch to a different IV that is dynamically
  dead and as such may be arbitrarily poison. This patch will correct
  nowrap flags in some but not all cases where this happens. This is
  related to the adoption of IR nowrap flags for the pre-inc addrec.
  (See some of the switch_to_different_iv tests, where flags are not
  dropped or insufficiently dropped.)

  Finally, there are likely similar issues with the handling of GEP
  inbounds, but we don't have a test case for this yet.

Pull in r362971 from upstream llvm trunk (by Philip Reames):

  Prepare for multi-exit LFTR [NFC]

  This change does the plumbing to wire an ExitingBB parameter through
  the LFTR implementation, and reorganizes the code to work in terms of
  a set of individual loop exits. Most of it is fairly obvious, but
  there's one key complexity which makes it worthy of consideration.
  The actual multi-exit LFTR patch is in D62625 for context.

  Specifically, it turns out the existing code uses the backedge taken
  count from before a IV is widened. Oddly, we can end up with a
  different (more expensive, but semantically equivelent) BE count for
  the loop when requerying after widening.  For the nestedIV example
  from elim-extend, we end up with the following BE counts:
  BEFORE: (-2 + (-1 * %innercount) + %limit)
  AFTER: (-1 + (sext i32 (-1 + %limit) to i64) + (-1 * (sext i32 %innercount to i64))<nsw>)

  This is the only test in tree which seems sensitive to this
  difference. The actual result of using the wider BETC on this example
  is that we actually produce slightly better code. :)

  In review, we decided to accept that test change.  This patch is
  structured to preserve the old behavior, but a separate change will
  immediate follow with the behavior change.  (I wanted it separate for
  problem attribution purposes.)

Pull in r362975 from upstream llvm trunk (by Philip Reames):

  [LFTR] Use recomputed BE count

  This was discussed as part of D62880.  The basic thought is that
  computing BE taken count after widening should produce (on average)
  an equally good backedge taken count as the one before widening.
  Since there's only one test in the suite which is impacted by this
  change, and it's essentially equivelent codegen, that seems to be a
  reasonable assertion.  This change was separated from r362971 so that
  if this turns out to be problematic, the triggering piece is obvious
  and easily revertable.

  For the nestedIV example from elim-extend.ll, we end up with the
  following BE counts:
  BEFORE: (-2 + (-1 * %innercount) + %limit)
  AFTER: (-1 + (sext i32 (-1 + %limit) to i64) + (-1 * (sext i32 %innercount to i64))<nsw>)

  Note that before is an i32 type, and the after is an i64.  Truncating
  the i64 produces the i32.

Pull in r363613 from upstream llvm trunk (by Philip Reames):

  Fix a bug w/inbounds invalidation in LFTR (recommit)

  Recommit r363289 with a bug fix for crash identified in pr42279.
  Issue was that a loop exit test does not have to be an icmp, leading
  to a null dereference crash when new logic was exercised for that
  case.  Test case previously committed in r363601.

  Original commit comment follows:

  This contains fixes for two cases where we might invalidate inbounds
  and leave it stale in the IR (a miscompile). Case 1 is when switching
  to an IV with no dynamically live uses, and case 2 is when doing
  pre-to-post conversion on the same pointer type IV.

  The basic scheme used is to prove that using the given IV (pre or
  post increment forms) would have to already trigger UB on the path to
  the test we're modifying. As such, our potential UB triggering use
  does not change the semantics of the original program.

  As was pointed out in the review thread by Nikita, this is defending
  against a separate issue from the hasConcreteDef case. This is about
  poison, that's about undef. Unfortunately, the two are different, see
  Nikita's comment for a fuller explanation, he explains it well.

  (Note: I'm going to address Nikita's last style comment in a separate
  commit just to minimize chance of subtle bugs being introduced due to
  typos.)

  (Recommit of r363293 which was reverted when a dependent patch was.)

  As pointed out by Nikita in D62625, BackedgeTakenCount is generally

  backedge taken count - one which only applies if a particular exit is
  taken - is called a ExitCount in SCEV code, so be consistent here.

Pull in r364709 from upstream llvm trunk (by Nikita Popov):

  [LFTR] Fix post-inc pointer IV with truncated exit count (PR41998)

  Fixes https://bugs.llvm.org/show_bug.cgi?id=41998. Usually when we
  have a truncated exit count we'll truncate the IV when comparing
  against the limit, in which case exit count overflow in post-inc form
  doesn't matter. However, for pointer IVs we don't do that, so we have
  to be careful about incrementing the IV in the wide type.

  I'm fixing this by removing the IVCount variable (which was ExitCount
  or ExitCount+1) and replacing it with a UsePostInc flag, and then
  moving the actual limit adjustment to the individual cases (which
  are: pointer IV where we add to the wide type, integer IV where we
  add to the narrow type, and constant integer IV where we add to the
  wide type).

GCC 4.1 and Binutils 2.17 (base has GCC 4.2.1 and Binutils 2.17), and is a
more secure PLT format, using a read-only linkage table, with the dynamic
linker populating a non-executable index table.

This is the libc, rtld, and kernel support only.  The toolchain and build
parts will be updated separately.

592bbe54d9 The variable names in the description of the port number usage is
inconsistent. This patch fixes that and improves the precision of
the description.
Thanks to Tom Marcoen for reporting the issue and providing an
initial patch, on which this change is based.

ca3075599a Teach readelf about some OpenBSD ELF program headers
- Add constants for OpenBSD wxneeded, bootdata and randomize to the
  FreeBSD elf_common.h file. This is the file that gets used by the
  elftoolchain library.
- Update readelf and elfdump utilities to decode these program headers
  if they are encountered.

Note: FreeBSD has it's own version of elfdump(1), which will be updated
in a subsequent commit. I am adding it here anyway because this diff is
going to be submitted upstream.

bc589b723e elfcopy: Use libelftc's string table routines to build .shstrtab.
This replaces some hand-rolled routines and is substantially faster
since libelftc uses a hash table for lookups and insertions, whereas
elfcopy would perform a linear scan of the table.

dc2282fc8b elfcopy: Use elf_getscn() instead of iterating over all sections.
When removing a section, we would loop over all sections looking for
a corresponding relocation section.  With r348652 it is much faster
to just use elf_getscn().
