Chris Lattner 971bbcb43a Fix Type::isSized() to realize that "{ opaque }" is not sized 
llvm-svn: 14585
 2004-07-02 23:20:17 +00:00
Chris Lattner 49df6cefa5 Do not call getTypeSize on a type that has no size

Chris Lattner a65b4eac3b Revert patches 1.79 and 1.80 which had to do with dead MBB's. Now that they 
don't exist, we don't have to pretend to handle them.

 2004-07-02 05:52:23 +00:00
Chris Lattner 55256dbf9b Fix potential problems with unreachable basic blocks. 
Also, while noone's looking, add support for constant expressions.  Wait,
I said not to look!

llvm-svn: 14566
 2004-07-02 05:49:11 +00:00
Chris Lattner 3594324248 Fix all of those problems that the PPC backend has running 176.gcc :)

Chris Lattner 6c322ecc31 Remove dead blocks 
llvm-svn: 14564
 2004-07-02 05:46:41 +00:00
Chris Lattner 693244fb33 Add a trivially simple pass to delete unreachable blocks from the CFG. This 
pass is required to paper over problems in the code generator (primarily
live variables and its clients) which doesn't really have any well defined
semantics for unreachable code.

The proper solution to this problem is to have instruction selectors not
select blocks that are unreachable.  Until we have a instruction selection
framework available for use, however, we can't expect all instruction
selector writers to do this.  Until then, this pass should be used.

Brian Gaeke e1a136fb4b Get rid of a dead variable, and fix a typo in a comment.

 2004-07-02 05:30:01 +00:00
Brian Gaeke 186e3d1098 Add M_TERMINATOR_FLAG to terminator instructions (branches and returns). 
Also, the RETURN instructions are not used in the sparcv9 backend.

llvm-svn: 14559
 2004-07-02 04:57:37 +00:00
Brian Gaeke fb894bd864 RETURN instructions are not used in the sparc backend. 
When in doubt, stamp it out!!

Misha Brukman 24a0371791 * Follow the PowerPC convention of leaving 24 bytes for linking on the stack. 
* Also leave space for spilling integer registers (this should be calculated)

llvm-svn: 14554
 2004-07-01 21:35:00 +00:00
Misha Brukman d028593c6e * Get rid of constant-expr handling code: we use the ConstantExpr lowering pass 
* Use the SetCC handling code in the format of Brian's V8
* Add FIXMEs where calls to functions are being made without adding them to the
  Module first... they cause missing symbols at assembly-time.

Misha Brukman d575287551 * Do not allocate r0 as we use it indiscriminantly in the instr selector. 
* Do not define CR register class because we don't (yet) have the i4 type

Chris Lattner 9a60c532a8 Make sure that we destroy the MBB's, with all of their instructions, before 
any other data structures

llvm-svn: 14524
 2004-07-01 06:29:07 +00:00
Chris Lattner c85535c8be Now that MachineFunction/MachineBasicBlock keep a mapping of blocks to ID #'s 
use them instead of a local LiveVariables numbering

llvm-svn: 14523
 2004-07-01 06:15:32 +00:00
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 
llvm-svn: 14520
 2004-07-01 06:02:07 +00:00
Chris Lattner 6c375e4926 Start using MBB numbers directly instead of going through the live variables 
map.

llvm-svn: 14518
 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.

Misha Brukman b9125f462d Fix indentation to be 2 spaces. 
llvm-svn: 14512
 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

llvm-svn: 14509
 2004-06-30 21:54:12 +00:00
Misha Brukman 04f07b4589 visitSetCondInst() takes a parameter of type `SetCondInst'

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.

llvm-svn: 14505
 2004-06-29 23:45:05 +00:00
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

llvm-svn: 14504
 2004-06-29 23:40:57 +00:00

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

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.

 2004-06-29 23:24:14 +00:00
