both cases they are looking for non-external variables/functions that do
not have internal linkage. Using "!isExternal()" is a little more
understandable than "hasInitializer()"

Otherwise, clients who call ParseAllFunctionBodies will attempt to parse
the function bodies twice, which is (uh) very very bad (tm).
This fixes gccld on python.

LLVM make the very reasonable assumption that constant expressions will
have at least one operand! :)

Use sys::MappedFile instead of ReadFileIntoAddressSpace and
UnmapFileFromAddressSpace. sys::MappedFile has the nice property that it
cleans up after itself so exception handling can be removed.

a different algorithm that was extremely inefficient for instructions with
many operands.
This reduces the time of this code snippet from .23s for 176.gcc to 0.03s
in a debug build, which speeds up total llvm-dis time just barely.
It's more of a code cleanup than a speedup.

This fixes a bug with llvm-ar not being able to read archives produced by
llvm-ranlib when there are members with odd long file name lengths.

* ensure trailing spaces are eliminated so they don't factor into the
length of a member's name.
* make sure all the bytes of a name are written even if the name ends in
multiple null characters (bug in OSX ar)
* make sure we provide the full member name when searching for symbols so
the module name is not accidentally duplicated.

* Fix a bug in name truncation \
* Add comments before functions \
* Get rid of functions that are now inlined into the header \
* Do not have Archive doing symbol table printing \
* Put assert comments into the assert so they print out \

ignore any trailing garbage on bytecode files. Thanks to Brian for digging

Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

CompactionTable really needs to be emitted. This is not a straight forward
computation, hence the need for a member function here.

- 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.

- 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.

Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions
when analyzing bytecode.

- 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.

- Writer will now align nothing
- Reader now only expects alignment for version 3 or earlier

- 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.

- Remove tabs
- Standardize use of space around ( and ).
- Consolidate the ConstantPlaceHolder class
- Rename two methods to be more meaningful (ParseType, ParseTypes)
- Correct indentation of blocks
- Add documentation
- Convert input dependent asserts to error(...) so it throws instead.
Provide placeholder implementations of read_float and read_double that
still read in platform-specific endianess. When I figure out how to do
this without knowing the endianess of the platform, it will get implemented
correctly.

- get rid of PARSE_ERROR macro
- add error(std::string) function
- use error(std::string) for all errors
- make input dependent asserts call error(std::string) instead
- ensure asserts are only for logic bugs, not input discrepancies.

global type plane starts with a length and the TypeTyID value to identify
the type plane has having type definitions. This doesn't happen in 1.3
because the types are read from a known position in the file. However, the
TypeTyID must be read in (and ignored) if its a 1.2 bytecode file.
