Personally, I think that documentation is as important as code.  Increase
the visibility of dox changes

Eliminate an explicit use of the LLVM basic block, using getParent instead,
which simplifies the code

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13707 91177308-0d34-0410-b5e6-96231b3b80d8

Changed clone to be const.
Changed copy constructor to set parent, prev, and next pointers to null.

Create a new style for tables that have no width (.doc_table_nw) so the
table doesn't stretch across the whole page. Change for BytecodeFormat.html

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13699 91177308-0d34-0410-b5e6-96231b3b80d8

Add some notes to myself, no functional changes

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13695 91177308-0d34-0410-b5e6-96231b3b80d8

minor wording change

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13694 91177308-0d34-0410-b5e6-96231b3b80d8

Fix cases where we missed inlining some more obvious candidates because the
caller was in an SCC.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13693 91177308-0d34-0410-b5e6-96231b3b80d8

Simplify the interface and remove an unneeded #include

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13692 91177308-0d34-0410-b5e6-96231b3b80d8

Fairly substantial changes to update the alias analysis we are querying as
we make the transformation.  This allows us to use interprocedural alias
analyses successfully.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13691 91177308-0d34-0410-b5e6-96231b3b80d8

Adjust to the changes in the AliasSetTracker interface

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13690 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for replacement of formal arguments with simpler expressions.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13689 91177308-0d34-0410-b5e6-96231b3b80d8

Implement the -lowergc pass which is used by code generators (like the CBE)
that do not have builtin support for garbage collection.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13688 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13685 91177308-0d34-0410-b5e6-96231b3b80d8

Changes to work with the changes to the AliasAnalysis interface.  The -no-aa
class is now in the BasicAliasAnalysis.cpp file

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13684 91177308-0d34-0410-b5e6-96231b3b80d8

Move the -no-aa AA implementation into this file since both of these
alias analysis implementations are special: they do not autoforward to a
chained implementation of alias analysis

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13683 91177308-0d34-0410-b5e6-96231b3b80d8

Updates to work with the new auto-forwarding AA interface changes

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13682 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a really nasty bug with the -disable-ds-field-sensitivity option

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13681 91177308-0d34-0410-b5e6-96231b3b80d8

Update to match the autochaining interface that the AA interface uses

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13680 91177308-0d34-0410-b5e6-96231b3b80d8

Implement the interfaces to update value numbering information.  Add an
assert.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13679 91177308-0d34-0410-b5e6-96231b3b80d8

Several *major* changes to the AA interfaces:

1. Provide interfaces so that clients can update alias analyses to reflect
   the changes made by the transformations.
2. Change how alias analysis implementations work overall.  In particular,
   now clients will automatically forward to chained AA implementations: they
   don't have to remember to do it themselves.

Add interfaces to update value numbering results

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13677 91177308-0d34-0410-b5e6-96231b3b80d8

Rename a method

Make use of the new doc_author class.  "Seperate content from presentation" they said.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13675 91177308-0d34-0410-b5e6-96231b3b80d8

Lots of minor cleanups and clarifications

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13674 91177308-0d34-0410-b5e6-96231b3b80d8

Lots of minor fixes and formatting improvements

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13671 91177308-0d34-0410-b5e6-96231b3b80d8

Update the coding standards, removign the bit about avoiding exceptions and
rtti (they shouldn't be used in the main compiler, but that's because
optimizations aren't allowed to fail!)

Remove the big section about iterators, because people who do not know what
they are doing shouldn't be writing them.  :)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13670 91177308-0d34-0410-b5e6-96231b3b80d8

Substantially expand and update the alias analysis documentation, including
adding blurbs about all of the implementations we have

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13669 91177308-0d34-0410-b5e6-96231b3b80d8

Various changes to make the docs look nicer.  Add a new doc_author class.

The one thing that someone (misha?) should look at is fixing doc_code so that it sizes to fit the code instead of going to the right margin all of the way.  Fixing it at a particular number of pixels was just wrong. :)

Add a new document describing the LLVM accurate garbage collection support.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13667 91177308-0d34-0410-b5e6-96231b3b80d8

Add a simple implementation of Andersen's interprocedural pointer analysis

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13666 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed up my changes to add support for cloning Machine Instructions.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13665 91177308-0d34-0410-b5e6-96231b3b80d8

Remove virtual destructor from InstVisitor. This class should never be
used through a base pointer/reference so inproper destruction should
never be an issue. Removing this last virtual function also saves 4
bytes off each InstVisitor instance.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13664 91177308-0d34-0410-b5e6-96231b3b80d8

Revert back to the previous version, as it doesn't work with mozilla, and people REALLY CAN just click the link. :)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13662 91177308-0d34-0410-b5e6-96231b3b80d8

Adding support to clone MachineInstr

Added a "Miscellaneous Improvements" section to cover things like the
Bytecode File Format documentation, getting all documents in HTML 4.01
(Strict) compliance, and any other minor improvement that shoud be noted.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13660 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13659 91177308-0d34-0410-b5e6-96231b3b80d8

Additional content describing variable bit rate encoding, correcting the
definition of the signature block and module block, and adding definitions
of the global type pool and symbol table. More still to come.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13658 91177308-0d34-0410-b5e6-96231b3b80d8

Put back the inlined bug list. Use the OBJECT tag to make it HTML-4.01
(Strict)-compliant.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13655 91177308-0d34-0410-b5e6-96231b3b80d8

Remember the set of leaders.  Also compute on demand and cache the equiv
class for each leader.   Finally, rename Elem2ECLeaderMap to Elem2LeaderMap
(most of the changed lines are only due to the latter).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13651 91177308-0d34-0410-b5e6-96231b3b80d8

Add getCaller() method.

Inline both direct and indirect callees in the CBU phase because
a direct callee may have indirect callees and so may have changed.

Complete rewrite of the code that merges DS graphs for equivalence classes
of functions called at a common call site.  The rewrite inlines the
resulting graphs bottom-up on the SCCs of the CBU call graph.  It also
simplifies the merging of equivalence classes by exploiting the fact that
functions in non-trivial SCCs are already merged.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13645 91177308-0d34-0410-b5e6-96231b3b80d8

Fix a typo in the head-of-file comment.
Rewrite the comments about the different versions of BuildMI, to

Some additional data added to the bytecode specification.

Added an initial template/overview for documentation of the LLVM Bytecode
file format. This format is being extracted from the source code and the
small recesses of Chris' brain.

It's not clear to me whether the old version was correct C++ code, but in

Fix to make the CBE always emit comparisons inline.  Hopefully this will
fix the really bad code we're getting on PPC.

Fix a bug in outputting branches to constant PCs. Since the PC is supplied as
a full 64-bit address, it must be adjusted to fit in the branch instruction's
immediate field. (This is only used in the reoptimizer, for now.)

Move RemapInstruction() to ValueMapper, so that it can be shared with
CloneTrace, and because it is primarily an operation on ValueMaps.  It
is now a global (non-static) function which can be pulled in using
ValueMapper.h.
