Chris Lattner 531f9e92d4 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

bytecode file members or not.
Patch Contributed By Adam Treat

llvm-svn: 20338
 2005-02-26 22:00:32 +00:00
Chris Lattner 75f5b42624 use more specific cast. 
llvm-svn: 20297
 2005-02-24 05:26:04 +00:00
Reid Spencer 8d0f126b74 Make the check for global variables the same as the one for functions. In 
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()"

llvm-svn: 20155
 2005-02-13 18:12:20 +00:00
Chris Lattner 147c561432 Make sure to clear the LazyFunctionLoadMap after we ParseAllFunctionBodies. 
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-svn: 20152
 2005-02-13 17:48:18 +00:00
Chris Lattner 1b9f9c5f67 Do not put internal symbols into the symbol table. This shrinks the symbol 
table for archives in common cases, and prevents trying to resolve a
external reference with an internal reference.  This shrinks the libpython.a
symbol table from 126302 to 19770 bytes.

llvm-svn: 20151
 2005-02-13 17:42:11 +00:00
Chris Lattner ccf22fb182 Fix the regressions my User changes introduced. Apparently some parts of 
LLVM make the very reasonable assumption that constant expressions will
have at least one operand! :)

llvm-svn: 19943
 2005-01-31 01:11:13 +00:00
Chris Lattner 616b8fc630 Adjust to changes in User class and minor changes in instruction ctors. 
llvm-svn: 19894

Reid Spencer 9e7acd465e For PR351: 
Remove unix specific code (use of errno and read) from the reader.
Thanks to Jeff Cohen for pointing this out.

llvm-svn: 19081

llvm-svn: 19056
 2004-12-20 03:23:46 +00:00
Reid Spencer 9329172767 For PR351: 
* Remove #inclusion of FileUtilities.h, not needed any more.
* Convert getUniqueFilename -> sys::Pat::makeUnique()

llvm-svn: 18948
 2004-12-15 01:51:56 +00:00
Reid Spencer cd89ca3040 For PR351: 
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.

llvm-svn: 18902
 2004-12-13 18:25:27 +00:00
Reid Spencer ac9fe82875 Make sure the Archive gets deleted if there's an error. 
llvm-svn: 18869
 2004-12-13 03:22:31 +00:00

Reid Spencer 5ccfd5a48b Path::get -> Path::toString 
llvm-svn: 18785
 2004-12-11 00:14:15 +00:00
Chris Lattner 6225146f20 Remove a dead field, make the map go to integer type ID to hash better and 
avoid a getType.

llvm-svn: 18691
 2004-12-09 06:19:44 +00:00
Chris Lattner 2cdf54c0f0 Remove #include inadvertently added 
llvm-svn: 18686
 2004-12-09 04:53:17 +00:00
Chris Lattner e44907012a Eliminate this ugly hack. This was put back in when replaceAllUsesOf used 
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.

llvm-svn: 18685
 2004-12-09 04:51:50 +00:00
Reid Spencer ef510c0279 Provide more information in the error message that occurs when there are 
unresolved constants remaining.

llvm-svn: 18502
 2004-12-04 22:19:53 +00:00
Chris Lattner 8145bd5006 Check in some patches for better assertions 
llvm-svn: 18500
 2004-12-04 21:28:47 +00:00
Chris Lattner 8f97278c49 Do not allow bytecode files with unresolved references to be read. Doing 
so lets wierd ConstantPlaceholder objects sneak into the system which
confuses it greatly.

llvm-svn: 18487
 2004-12-04 05:28:27 +00:00
Chris Lattner 37a14496c5 RevisionNum is read by error(), initialize it early.

llvm-svn: 18044
 2004-11-20 07:29:40 +00:00
Reid Spencer 78e12c73e5 Correct the computation of when to add the padding. It is not based on the 
member's size. It is based on the oddness/evenness of the file pointer.
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.

llvm-svn: 17997
 2004-11-19 17:08:00 +00:00
Chris Lattner ddf3b7997f Add note that this is for old bytecode files.

Reid Spencer 39a0347b79 Make findModulesDefiningSymbols modify its symbols argument so we can \ 
eliminate symbols defined by the archive efficiently

llvm-svn: 17976
 2004-11-19 03:18:22 +00:00
Reid Spencer 67c46c8d70 Fix some things for Mac OSX archives: 
* 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.

llvm-svn: 17918
 2004-11-17 18:28:29 +00:00
Reid Spencer b58bf5fa28 Make sure we parse bytecode with a module identifier that reflects the full 
name of the module: "Archive.a(object.o)"

llvm-svn: 17910
 2004-11-17 16:14:21 +00:00
Reid Spencer 0dea46fe67 Despite documentation to the contrary, Mac OSX and BSD 4.4 archive formats 
*do* include the length of the long file in the length of the member and
they are *not* null terminated.

 2004-11-15 21:55:06 +00:00
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.

llvm-svn: 17854
 2004-11-15 21:46:40 +00:00
Chris Lattner 55d85402f6 Make functions default to having external linkage if they have no 
FunctionBlock.

llvm-svn: 17853
 2004-11-15 21:43:03 +00:00
Reid Spencer cbd9aeb587 * Make sure the string table gets read even if there isn't a foreign 
symbol table.
* Make sure we update the file pointer for each member when rebuilding the
  symbol table.

Chris Lattner d7dc1ecd42 The system ranlib on darwin occasionally adds two extra newlines to the 
end of files, breaking the CFE build.  As a gross hack around this,
ignore any trailing garbage on bytecode files.  Thanks to Brian for digging
in and identifying the problem.

Reid Spencer 7c16caa336 Changes For Bug 352 
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/.

 2004-08-27 00:43:51 +00:00
Reid Spencer 248c06dcea Prevent an empty compaction table from being written to the bytecode file. 
llvm-svn: 16063
 2004-08-27 00:38:44 +00:00
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.

llvm-svn: 16062

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: 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.

 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.

Chris Lattner 74635dc879 Fix a serious bug in the double constant reader. In particular, because 
(At[3] << 24) is an int type and it is being coerced to uint64_t, it was
getting sign extended, causing us to get FFFFFFFFxxxxxxxx constants all of
the time.

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.
