Misha Brukman 4c70105c4c Fix some grammar.

Chris Lattner a88d667487 Do not use .xword and friends to emit zeros on V9. Apparently there are issues 
with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the
same as 8 .byte 0's).  Because we do not know when or when we are not aligned,
just emit bytes like the old V9 asmprinter did.

Reid Spencer 5b81eea7a5 Moved small examples from /projects/SmallExamples to /examples. 
Made the "ModuleMaker" into an example since its just one source file.

llvm-svn: 16003
 2004-08-23 19:29:54 +00:00
Reid Spencer b987b7cede Moved the "SmallExamples" out of the /projects directory and into a new 
/examples directory. History was maintained. These programs do not need to
be configured but things in /projects must be.

Reid Spencer 300396971c Fix Title line 
Make the "DIRS" option descend any directory with a Makefile.

Misha Brukman 39efd01983 Note: do not use GNU binutils under AIX, they're not stable. 
llvm-svn: 16000
 2004-08-23 17:54:45 +00:00
Reid Spencer 06afee6ede Change the makefile back so it descends any directory with a Makefile.

Allow CRLF as a line terminator (as well as plain LF)

llvm-svn: 15993
 2004-08-22 18:02:13 +00:00
Reid Spencer ed09afc536 Shorten lines so this file can be used as the documentation example 
directly. Remove -pre (experimental pass).

llvm-svn: 15989
 2004-08-21 23:40:49 +00:00
Reid Spencer 5a2dfbae3d First complete version. The details of configuration are now correctly 
stated. PLEASE REVIEW THIS DOCUMENT NOW! :)

llvm-svn: 15988
 2004-08-21 22:37:42 +00:00
Reid Spencer f39f66e3ef Initial checkin of a pass to lower packed operations to scalars operations. 
This also registers the pass with opt with a -lower-packed command line
option.

Patch contributed by Brad Jones.

 2004-08-21 21:39:24 +00:00
Reid Spencer d6dd465326 Correct to change interface of the analyzer. 
llvm-svn: 15986
 2004-08-21 21:00:24 +00:00
Reid Spencer 2807accdc5 Bytecode Analyzer Cleanup: 
- Rearrange output order to make more sense
- Make only the function level output count as "detailed"
- Output dump output directly to stream, don't buffer it.
- Fix counting of block sizes
- Implement new handlers for number of types, dependent libs, target triple
- Compute the size of block headers.

llvm-svn: 15985
 2004-08-21 20:58:19 +00:00
Reid Spencer 9874c63314 Get rid of an extraneous local variable. 
llvm-svn: 15984
 2004-08-21 20:53:56 +00:00
Reid Spencer 6639333f20 Two Changes: 
- Pass the output stream to the analyzer so it can write its output there
  directly instead of buffering it.
- Don't pass a boolean to ParseBytecode because its not needed any more.

llvm-svn: 15983
 2004-08-21 20:52:03 +00:00
Reid Spencer 8631bc3aaa Add boolean file format flags in preparation for version 5 bytecode. 
Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions
when analyzing bytecode.

llvm-svn: 15982
 2004-08-21 20:50:49 +00:00
Reid Spencer 191aa30ac1 Bytecode Reader Cleanup: 
- provide the correct conversion for ModuleBlockID in read_block (a potential
  bug but not actually exploited because reading module block ids doesn't
  use read_block).
- install support for handleTypeList handler
- install support for handleDependentLibrary handler
- install support for handleTargetTriple handler
- clean up comments, output strings,
- ensure that processing function arguments doesn't SIGSEGV if one of the
  arguments is a null pointer (yeah, it happened .. weird)
- prepare for version 5 bytecode by documenting what will change.

llvm-svn: 15981
 2004-08-21 20:49:23 +00:00
Reid Spencer c039e6301a Dump the DependentLibsBlockID, its not a block, its just a list inside the 
globals info block. Add an enumerator for getting the number of enumerators
so we can range check in assertions.

llvm-svn: 15980
 2004-08-21 20:42:28 +00:00
Nate Begeman 45b0b7cd7c Back out branchless SetCC code. While it helped a lot in some cases, it 
hurt a lot in others.  Instead, improve branching version of SetCC and
Select instructions.  The old code will be in CVS should we ever need to
dig it up again.

llvm-svn: 15979
 2004-08-21 20:42:14 +00:00
Reid Spencer f9ce66b75a Add new methods: 
- get the total number of types in the global type list
- handle dependent libraries
- handle target triple

llvm-svn: 15978
 2004-08-21 20:41:12 +00:00
Reid Spencer 83c307de5d Bytecode Analyzer cleanup: 
- don't save the "dump" output, just emit it
- record the bc version number
- record info about the dependent libraries and target triple
- use the correct enumeration as the index on the block size map

llvm-svn: 15971
 2004-08-21 20:09:46 +00:00
Chris Lattner 36ba4bb042 Register info alignment is in bits, frame object alignment is (currently) in 
bytes.

llvm-svn: 15970

llvm-svn: 15968
 2004-08-21 19:51:17 +00:00
Chris Lattner f76ccd43b8 Now that we have per-register spill size/alignment info, remove more uses 
of getRegClass

llvm-svn: 15967
 2004-08-21 19:45:10 +00:00
Chris Lattner a6d34d9e19 Infer the spillsize/alignment of a register based on the register classes 
it is embedded into.

llvm-svn: 15964
 2004-08-21 19:11:03 +00:00
Reid Spencer 04f4d52d9e Examine the type code in the setcc class of instructions and if it 
is a PackedType, throw an error. Temporary solution.

llvm-svn: 15959
 2004-08-21 02:17:39 +00:00
Chris Lattner 8439f382b6 Fix a nasty bug that Nate ran into. In particular, instead of emitting a 2+MB 
error message, print out:

llvm-link: error linking in 'g.2.rbc': Global Variable Collision on
' %struct.D_Reduction* %d_reduction_10_gram' - External linkage globals have
different initializers

That's a bit more concise, huh?

llvm-svn: 15958
 2004-08-21 00:50:59 +00:00
Reid Spencer 7f9971f349 Change @ -> % in config files. @name@ might be needed for config files to 
themselves be configured via autoconf so its not a good substitition syntax
for llvmc. Furthermore % is more llvmish :)
