Chris Lattner 449af59c7e Change MBB autonumber a bit to get the reverse mapping as well as a forward 
mapping

Chris Lattner a47455dbd3 Instance var no longer exists

Chris Lattner 6b2ac89e78 Change the implementation of the autonumbering for MBB's a bit to provide 
the reverse mapping as well as the mapping from MBB->unsigned

Chris Lattner 6c375e4926 Start using MBB numbers directly instead of going through the live variables 
map.

 2004-07-01 04:29:47 +00:00
Chris Lattner 7c77fd50e7 Instead of building a private numbering of MBB's use brg's nifty auto-numbering. 
Also convert df_iterator -> df_ext_iterator for subsequent stuff I'm doing.

Chris Lattner 5cc223a7e2 Fix testcase 
llvm-svn: 14516
 2004-07-01 04:11:35 +00:00
Chris Lattner 8785e03d7c -debug option does not exist in a release build

 2004-07-01 04:10:15 +00:00
Chris Lattner eee347209f Fix testcase. For some reason this was failing only with a release build and 
not with a debug build?  Rather testrunner only caught it in that case.

 2004-06-30 22:11:03 +00:00
Misha Brukman 0648a903c7 * Coalesce the handy CALL* alias opcodes with the standard ones 
* Congregate more branch-and-link opcodes together
* Mark FP, CPR, and special registers as volatile across calls

llvm-svn: 14511
 2004-06-30 22:00:45 +00:00
Misha Brukman 299fa1b147 * Allow more registers to be allocated from the general register pool 
* Define the condition register class

llvm-svn: 14510
 2004-06-30 21:54:50 +00:00
Misha Brukman fee5a22f8a * Inquire about the number of operands from the instruction directly 
* Only check for a register if we are sure the instruction has one allocated

Jonathan Manton aff4a6a11b Fixed the tutorial to indicate that we needed to use the llvm namespace. 
llvm-svn: 14507
 2004-06-30 18:10:30 +00:00
Misha Brukman 2b9106f808 Always assume a function may have calls because the printer may add `bl' to get 
the PC in a code sequence for global variables.

llvm-svn: 14506
 2004-06-30 00:09:12 +00:00
Misha Brukman 351646f31e * Don't save LR when outputting globals: it's already saved on the stack once 
for the function
* Registers aren't necessarily sequential wrt their enums, don't rely on it
  when emitting function arguments into sequential registers
* Remove X86-specific comments about AL/BL/AH/BH/EDX/etc
* Add an abort() for an unimplemented signed right shift
* The src operand for a GEP was never emitted!  Fixed.
* We can skip zero-valued GEP indices as they are no-ops.

"Hello, World!" now works.

Misha Brukman c794feab51 * Stop using BBNumbering, we don't really need it 
* Only increment labelNumber once, because it's used by both Load{hi,lo}Addr
* There is no .bss section on PowerPC
* Use .align 2 instead of other random numbers

Reid Spencer b1076c4231 Fix order and line length of fixed bugs. 
llvm-svn: 14503
 2004-06-29 23:39:24 +00:00
Misha Brukman d409669877 Set up the prologue and epilogue to be more like the manual and GCC output. 
llvm-svn: 14502
 2004-06-29 23:38:26 +00:00
Misha Brukman 7454c6fff0 * Use LA instead of LWZ for LoadLoAddr 
* Specify the isCall bit and caller-save registers for some call instrs

Misha Brukman 5459dfb47b Only allocate non-volatile registers R13-31 (for now).

Reid Spencer 002dd98ce0 The analyzer code now lives in the bcreader library. The bcanalyzer lib 
is no more.

llvm-svn: 14498

Misha Brukman 4efe3da794 Lower ConstantExpressions before the code generator. 
llvm-svn: 14497
 2004-06-29 23:33:20 +00:00
Reid Spencer fddebf7ff2 Remove files no longer needed. ConstantReader and InstructionReader were 
integrated into Reader. Parser.* was just a bad idea. AnalyzerInternals.h
is no longer needed. ReaderPrimitives.h was integrated into Reader.h and
Reader.cpp. Dumper.cpp was integrated into Analyzer.cpp. ReaderInternals.h
became Reader.h. AnalyzerWrappers.cpp was integerated into
ReaderWrappers.cpp

llvm-svn: 14496
 2004-06-29 23:32:41 +00:00
Reid Spencer f4ec6383c0 This is a slimming down of the previous ReaderInternals.h that just 
declares the BytecodeReader class.

 2004-06-29 23:31:01 +00:00
Reid Spencer 284b7c7174 MAJOR REWRITE. 
- stop passing Buf/BufEnd to every function (now member vars)
- internalize things that used to be in a header file that no one else
  included/needed.
- Remove defunct BCR_TRACE lines
- Standardize error handling with the PARSE_ERROR macro.
- Integrate ConstantReader.cpp and InstructionReader.cpp and reorgnize
  the definition order so that gcc has a chance at optimizing this module
- Standardize case and style of method names.
- Eliminate unneeded header files
- Prepare for Type != Value (bug122) change by splitting Types into their
  own data structures.
- Implement the BytecodeHandler interface calls.
- Provide default implementation of BytecodeHandler interface.

llvm-svn: 14494
 2004-06-29 23:29:38 +00:00
Reid Spencer 891cb9d925 Adjustments to allow Bytecode Reading to support the BytecodeHandler 
interface which is called by the reader if a BytecodeHandler is provided.

llvm-svn: 14493
 2004-06-29 23:24:14 +00:00
Reid Spencer 351f6bf714 Merge Dumper.cpp and AnalyzerWrappers.cpp into this file. Also, adjust the 
dumping facility to produce useful output.

llvm-svn: 14492

Reid Spencer c7b9419add Analyzer moved to ../Reader directory. 
llvm-svn: 14491
 2004-06-29 23:21:53 +00:00
Reid Spencer 75923a4f93 Remove newly defunct Analyzer directory. 
llvm-svn: 14490
 2004-06-29 23:21:16 +00:00
Reid Spencer 5a45200992 Provide support for the BytecodeHandler interface which will be called by 
the bcreader if one is supplied to the bytecode reader's interface
functions.

llvm-svn: 14489
 2004-06-29 23:20:03 +00:00
Reid Spencer 53213ce347 Fix include guard 
Adjust comments
Make handlers for constants provide useful information.

 2004-06-29 23:18:52 +00:00
Reid Spencer d190ecc669 Adjust comments to match code. 
Allow analysis to return the module created by the bcreader.

Vikram S. Adve 1097ed8467 Restoring this file. 
llvm-svn: 14478
 2004-06-29 14:20:27 +00:00
Chris Lattner c5f9b356af The code generator should work with unreachable blocks. If not, then this 
is a bug that should be fixed in the code generator, not papered over with
the simplifycfg pass.  Eliminating this makes bugpoint much more useful

llvm-svn: 14477
 2004-06-29 07:20:16 +00:00
Chris Lattner e6e1b48023 I believe that the code generator now properly handles dead basic blocks. If not, 
this is a bug, and should be fixed.

llvm-svn: 14476
 2004-06-29 07:17:12 +00:00
Chris Lattner 4cda555346 In line with the previous patch, do not assert out if analyzing a dead basic block. 
llvm-svn: 14475

Chris Lattner 49b34f3f51 Do not dereference end iterators. It hurts when you do that.

 2004-06-29 06:56:51 +00:00
Chris Lattner 1a920d49f6 Fix a regression from r1.224. In particular, codegen a cast from double -> 
float as a truncation by going through memory.  This truncation was being
skipped, which caused 175.vpr to fail after aggressive register promotion.
