Chris Lattner 3b6bb48c16 Do not emit FunctionBlock blocks for external functions. This shrinks 
bytecode files by about 8 bytes per external function

Chris Lattner 94bd315c3f If a function is external, do not output a FunctionBlock for the function 
AT ALL.  This saves 11 bytes per external function from the bytecode file,
and is also required to make GhostLinkage work.

Reid Spencer 3b789ad2b8 Add the CompactionTableIsEmpty function so that we can determine if a 
CompactionTable really needs to be emitted. This is not a straight forward
computation, hence the need for a member function here.

Reid Spencer b2bdb943b5 bug 263: 
- encode/decode target triple and dependent libraries
bug 401:
- fix encoding/decoding of FP values to be little-endian only
bug 402:
- initial (compatible) cut at 24-bit types instead of 32-bit
- reduce size of block headers by 50%
Other:
- cleanup Writer by consolidating to one compilation unit, rem. other files
- use a std::vector instead of std::deque so the buffer can be allocated
  in multiples of 64KByte chunks rather than in multiples of some smaller
  (default) number.

Reid Spencer a64b62ef6a Prepare the writer for a non-broken implementation of writing floating 
point values. This will be fixed when I figure out how to do it correctly
without depending on knowing the endianess of a platform.

Reid Spencer bf2bce3f74 Implementation of SlotTable went into header file. Note that this header 
is currently not being used but is retained because it will be the basis
for a clean up of the SlotCalculator class.

Reid Spencer a52b0009ea Implement new output functions for types and compacted type planes. Also 
remove use of Type::TypeTyID and Type::TypeTy since Type no longer inherits
Value.

llvm-svn: 14610
 2004-07-04 11:45:47 +00:00
Reid Spencer 3cdb4e88e5 Add new methods outputTypes and outputCompactionTypes for handling Types 
separately from Values. This needed for bug 122.

llvm-svn: 14609
 2004-07-04 11:44:27 +00:00
Reid Spencer 88f3e0731e For bug 122: 
Separate Types from Values because Type no longer inherits from Value. The
changes for this are too numerous to list. In essence, any data structure
that contained a Value was doubled so that Types could be contained
similarly. New members include Types, TypeMap, CompactionTypes, and
CompactionTypeMap. Functions taking a Value* were overloaded with a variant
that takes a Type* that acts on the new data structures.

 2004-07-04 11:42:49 +00:00
Reid Spencer 25319569fb - Type::TypeTyID doesn't exist any more (bug 122) 
- Types don't have names any more, just write them on ostream directly

llvm-svn: 14606
 2004-07-04 11:37:54 +00:00
Reid Spencer 5ef4237089 Move SlotCalculator.h to lib/Bytecode/Writer since that is the only place 
that needs it after the Type != Value changes (bug 122).

Reid Spencer f2f34b3052 Use the SymbolTable::isEmpty() method instead of checking for no value 
planes. A SymbolTable could still have types in it! This fixes problems
with two regression tests that failed because a symbol table that only
contained types was being omitted from bytecode files. Thanks to Chris
for the reduced test case that helped find this immediately.

Reid Spencer 0aff01a239 Part of bug 122: 
This change removes the BuildBytecodeInfo flag from the SlotCalculator
class. This flag was needed to distinguish between the Bytecode/Writer
and the AsmWriter. Now that AsmWriter doesn't use SlotCalculator, we can
remove this flag and simplify some code. Also, some minor name changes
to CachedWriter.h needed to be committed (missed in previous commit).
