Chris Lattner 6754b827c6 Fix cases where we missed inlining some more obvious candidates because the 
caller was in an SCC.

llvm-svn: 13693
 2004-05-23 21:22:17 +00:00
Chris Lattner 8d7ff5e3dd Simplify the interface and remove an unneeded #include 
llvm-svn: 13692
 2004-05-23 21:21:35 +00:00
Chris Lattner 254f8f8ad5 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.

llvm-svn: 13691
 2004-05-23 21:21:17 +00:00
Chris Lattner 289ba2ac4d Adjust to the changes in the AliasSetTracker interface 
llvm-svn: 13690
 2004-05-23 21:20:19 +00:00
Chris Lattner e67dbc2ae2 Add support for replacement of formal arguments with simpler expressions. 
llvm-svn: 13689
 2004-05-23 21:19:55 +00:00
Chris Lattner 099c8cfe90 Implement the -lowergc pass which is used by code generators (like the CBE) 
that do not have builtin support for garbage collection.

llvm-svn: 13688
 2004-05-23 21:19:22 +00:00
Chris Lattner 9c251eb0ad Recognize and verify the new GC intrinsics.

llvm-svn: 13685
 2004-05-23 21:16:13 +00:00
Chris Lattner 62c37008a4 Changes to work with the changes to the AliasAnalysis interface. The -no-aa 
class is now in the BasicAliasAnalysis.cpp file

llvm-svn: 13684
 2004-05-23 21:15:48 +00:00
Chris Lattner 59c8ed8843 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

llvm-svn: 13683
 2004-05-23 21:15:12 +00:00
Chris Lattner e345f6b5ab Updates to work with the new auto-forwarding AA interface changes 
llvm-svn: 13682
 2004-05-23 21:14:27 +00:00

llvm-svn: 13681
 2004-05-23 21:14:09 +00:00
Chris Lattner befe4c510e Update to match the autochaining interface that the AA interface uses 
llvm-svn: 13680
 2004-05-23 21:13:51 +00:00
Chris Lattner 32502b8d4a Implement the interfaces to update value numbering information. Add an 
assert.

llvm-svn: 13679
 2004-05-23 21:13:24 +00:00
Chris Lattner 8f2b467feb 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.

llvm-svn: 13678

llvm-svn: 13676

 2004-05-23 21:06:01 +00:00
Chris Lattner 411eba181a Lots of minor fixes and formatting improvements 
llvm-svn: 13671
 2004-05-23 21:05:39 +00:00
Chris Lattner 1dab192f22 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.  :)

llvm-svn: 13670
 2004-05-23 21:05:07 +00:00
Chris Lattner 2a19d83689 Substantially expand and update the alias analysis documentation, including 
adding blurbs about all of the implementations we have

llvm-svn: 13669
 2004-05-23 21:04:01 +00:00
Chris Lattner e25f4fffff 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. :)

llvm-svn: 13668
 2004-05-23 21:03:30 +00:00
Chris Lattner f689d57f0f Add a new document describing the LLVM accurate garbage collection support. 
llvm-svn: 13667
 2004-05-23 21:02:20 +00:00
Chris Lattner 5758134505 Add a simple implementation of Andersen's interprocedural pointer analysis 
llvm-svn: 13666
 2004-05-23 21:00:47 +00:00
Tanya Lattner 9953d86e63 Fixed up my changes to add support for cloning Machine Instructions. 
llvm-svn: 13665
 2004-05-23 20:58:02 +00:00
Alkis Evlogimenos ee4dcae9ba 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.

llvm-svn: 13664
 2004-05-23 20:54:39 +00:00
Chris Lattner 23257069b6 Fix a couple misplaced div tags 
llvm-svn: 13663
 2004-05-23 20:42:08 +00:00
Chris Lattner f45d23b85c Revert back to the previous version, as it doesn't work with mozilla, and people REALLY CAN just click the link. :) 
llvm-svn: 13662

Reid Spencer 3e58f5880a 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.

llvm-svn: 13660
 2004-05-23 17:23:13 +00:00
Reid Spencer ac9cc8c82d Make the file HTML 4.01 (Strict) clean. 
llvm-svn: 13659
 2004-05-23 17:12:45 +00:00
Reid Spencer eca340ba12 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.

llvm-svn: 13658
 2004-05-23 17:05:09 +00:00
Alkis Evlogimenos 22acc1268d Put back the inlined bug list. Use the OBJECT tag to make it HTML-4.01 
(Strict)-compliant.

Vikram S. Adve 189d626ad6 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).

llvm-svn: 13651
 2004-05-23 08:05:14 +00:00
Vikram S. Adve 16f29f349d Add getCaller() method. 
llvm-svn: 13650
 2004-05-23 08:02:45 +00:00
Vikram S. Adve 159ed21b67 Inline both direct and indirect callees in the CBU phase because 
a direct callee may have indirect callees and so may have changed.

llvm-svn: 13649
 2004-05-23 08:00:34 +00:00
Vikram S. Adve c5e27638dd 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.

llvm-svn: 13645
 2004-05-23 07:54:02 +00:00
Vikram S. Adve f44d32d9e2 Fix size/offset assertion to allow negative offsets and folded nodes. 
llvm-svn: 13644

Brian Gaeke 74b08516e9 Fix a typo in the head-of-file comment. 
Rewrite the comments about the different versions of BuildMI, to
better emphasize their differences.

llvm-svn: 13642

Reid Spencer 257dbb00fe Some additional data added to the bytecode specification. 
llvm-svn: 13626
 2004-05-22 05:56:41 +00:00
Reid Spencer 9acd412316 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.

llvm-svn: 13625
 2004-05-22 02:28:36 +00:00
Reid Spencer deea18188e Removed the 64-bit fix from the "to do" list since the bug is fixed.

Chris Lattner 37c653a28e It's not clear to me whether the old version was correct C++ code, but in 
any case it's not portable.
