6ca8079c85 Pull in r265122 from upstream llvm trunk (by James Molloy):
Fix for pr24346: arm asm label calculation error in sub

  Some ARM instructions encode 32-bit immediates as a 8-bit integer
  (0-255) and a 4-bit rotation (0-30, even) in its least significant 12
  bits. The original fixup, FK_Data_4, patches the instruction by the
  value bit-to-bit, regardless of the encoding. For example, assuming
  the label L1 and L2 are 0x0 and 0x104 respectively, the following
  instruction:

    add r0, r0, #(L2 - L1) ; expects 0x104, i.e., 260

  would be assembled to the following, which adds 1 to r0, instead of
  260:

    e2800104 add r0, r0, #4, 2 ; equivalently 1

  The new fixup kind fixup_arm_mod_imm takes care of the encoding:

    e2800f41 add r0, r0, #260

  Patch by Ting-Yuan Huang!

This fixes label calculation for ARM assembly, and is needed to enable
ARM assembly sources for OpenSSL.

c371433e4a For clang, move the definition of FREEBSD_CC_VERSION into its own header
file, lib/clang/freebsd_cc_version.h, instead of reusing Version.inc.
The header is only included from one .cpp file in the clang tree.

This minimizes the number of .cpp files that need to be rebuilt if the
version is bumped.

b5e99283f4 Pull in r271548 from upstream llvm trunk (by me):
Only attempt to detect AVG if SSE2 is available

  Summary:
  In PR29973 Sanjay Patel reported an assertion failure when a certain
  loop was optimized, for a target without SSE2 support.  It turned out
  this was because of the AVG pattern detection introduced in rL253952.

  Prevent the assertion failure by bailing out early in
  `detectAVGPattern()`, if the target does not support SSE2.

  Also add a minimized test case.

  Reviewers: congh, eli.friedman, spatel

  Subscribers: emaste, llvm-commits

  Differential Revision: http://reviews.llvm.org/D20905

This should fix assertion failures ("Requires at least SSE2!") when
building the games/0ad port with CPUTYPE=pentium3.

Bryan Drewery
06a6cbdf5f Add FREEBSD_CC_VERSION which will be used to define __FreeBSD_cc_version.
The WITH_SYSTEM_COMPILER build option will rely on this value to determine what
__FreeBSD_cc_version the source tree will produce.  This value will be compared
against the /usr/bin/cc value to determine if a new compiler is needed.

Start with 1100002 which is 1 more than than the value we've had since
3.8.0 to ensure that all changes since then are present.

c43c22982e Limit Options.inc generation to desired targets
As mentioned in the Makefile there's an "atrocious" hack to generate a
different version of Options.inc.h, depending on the library being
built.

Remove the catch-all else case and limit it to specific libraries, so
that we don't accidentally use the Options.inc.h from clangdriver if a
future libary also uses Options.inc.h.

At least FAST_DEPEND won't even run 'make depend', so the code was
potentially broken with FAST_DEPEND anyhow.  The .dinclude directive
will ignore missing files rather than make them be fatal.

b9cd412e7b FAST_DEPEND: Always run depend via beforebuild which removes many hacks.
This will generate dependencies rather than depending on the previous behavior
of depending on the guessed OBJS: *.h dependecies or a user running
'make depend'.

Experimentation showed that depending only on headers was not enough and
prone to .ORDER errors.  Downstream users may also have added
dependencies into beforedepend or afterdepend targets.  The safest way to
ensure dependencies are generated before build is to run 'make depend'
beforehand rather than just depending on DPSRCS+SRCS.

Note that the OBJS_DEPEND_GUESS mechanism (a.k.a .if !exists(.depend) then
foo.o: *.h) is still useful as it improves incremental builds with missing
.depend.* files and allows 'make foo.o' to usually work, while this
'beforebuild: depend' ensures that the build will always find all dependencies.
The 'make foo.o' case has no means of a 'beforebuild' hook.

This also removes several hacks in the DIRDEPS_BUILD:
- NO_INSTALL_INCLUDES is no longer needed as it mostly was to work around
  .ORDER problems with building the needed headers early.
- DIRDEPS_BUILD: It is no longer necesarry to track "local dependencies" in
  Makefile.depend.

  These were only in Makefile.depend for 'clean builds' since nothing would
  generate the files due to skipping 'make depend' and early dependency
  bugs that have been fixed, such as adding headers into SRCS for the
  OBJS_DEPEND_GUESS mechanism.  Normally if a .depend file does not exist then
  a dependency is added by bsd.lib.mk/bsd.prog.mk from OBJS: *.h.  However,
  meta.autodep.mk creates a .depend file from created meta files and inserts
  that into Makefile.depend.  It also only tracks *.[ch] files though which can
  miss some dependencies that are hooked into 'make depend'.  This .depend
  that is created then breaks incremental builds due to the !exists(.depend)
  checks for OBJS_DEPEND_GUESS.  The goal was to skip 'make depend' yet it only
  really works the first time.  After that files are not generated as expected,
  which r288966 tried to address but was using buildfiles: rather than
  beforebuild: and was reverted in r291725.  As noted previously,
  depending only on headers in beforebuild: would create .ORDER errors
  in some cases.

  meta.autodep.mk is still used to generate Makefile.depend though via:
    gendirdeps: Makefile.depend
    .END: gendirdeps

  This commit allows removing all of the "local dependencies" in
  Makefile.depend which cuts down on churn and removes some of the
  arch-dependent Makefile.depend files.

  The "local dependencies" were also problematic for bootstrapping.

fdd1590a42 As submitted upstream in a review, avoid using undefined behavior in
llvm's LinkAllPasses.h.  This caused some of the calls not to be
emitted, if the optimization level was -O2 or higher.

Conversely, if you used -O1 or lower, calls to e.g.  RunningOnValgrind()
would be emitted, leading to link failures, because we did not include
Valgrind.cpp into libllvmsupport.  Therefore, add it unconditionally.

b1f92fa229 META MODE: Update dependencies with 'the-lot' and add missing directories.
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

3bed45ab81 META MODE: Rework [bootstrapped] tools PATH support.
- Support more of the toolchain from TOOLSDIR.
- This also improves 'make bootstrap-tools' to pass, for example,
  AS=/usr/bin/as to Makefile.inc1, which will tell cross-tools to use
  external toolchain support and avoid building things we won't be using
  in the build.
- Always set the PATH to contain the staged TOOLSDIR directories when
  not building the bootstrap targets.

  The previous version was only setting this at MAKE.LEVEL==0 and if the
  TOOLSDIR existed.  Both of these prevented using staged tools that were
  built during the build though as DIRDEPS with .host dependencies, such
  as the fix for needing usr.bin/localedef.host in r291311.
  This is not a common tool so we must build and use it during the build,
  and need to be prepared to change PATH as soon as it appears.

  This should also fix the issue of host dependencies disappearing from
  Makefile.depend and then reappearing due to the start of the fresh build not
  having the directory yet, resulting in the tools that were built not actually
  being used.
- Only use LEGACY_TOOLS while building in Makefile.inc1.  After r291317
  and r291546 there is no need to add LEGACY_TOOLS into the PATH for
  the pseudo/targets/toolchain build.
- Because the pseudo/targets/toolchain will now build its own
  [clang-]tblgen, the special logic in clang.build.mk is no longer needed.
- LEGACY_TOOLS is no longer used outside of targets/pseudo/bootstrap-tools
  so is no longer passed into the environment in its build.

0383be9bae META MODE: Fix rebuilding of lib/clang/include after clang-tblgen.host is
staged.

None of usr.bin/clang/clang-tblgen or its dependencies need
lib/clang/include, so there is no cyclic dependency here to worry about.
The issue came about because of workarounds to dependencies on clang
being optional.

Without this, the clang-tblgen called during the build would change
after it was staged for the host.  This would cause lib/clang/include to
rebuild due to changed build commands.
