Reid Spencer 9f4bb585f5 Remove potential platform portability issue with size of "int". 
llvm-svn: 19172
 2004-12-29 01:20:24 +00:00
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

Reid Spencer b5e10bb05d Remove the #include of llvm/Config/unistd.h as it is no longer needed. 
llvm-svn: 19067

Reid Spencer 9329172767 For PR351: 
* Remove #inclusion of FileUtilities.h, not needed any more.
* Convert getUniqueFilename -> sys::Pat::makeUnique()

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.

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 a204547e32 Implement error handling in OpenAndLoad* functions so the Linker can handle it. 
llvm-svn: 18853

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.

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.

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: 18386
 2004-11-30 16:58:18 +00:00
Reid Spencer 8a3312cab3 Compute the firstFileOffset correctly after reading the LLVM symbol table.

Reid Spencer 7a32486483 Distinguish between BSD4.4 and SVR4 symbol tables 
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. 
llvm-svn: 17991
 2004-11-19 16:24:05 +00:00
Reid Spencer fc9f779039 Don't save an iterator, just use post-increment. 
llvm-svn: 17981
 2004-11-19 03:44:10 +00:00
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: 17917
 2004-11-17 18:25:21 +00:00
Reid Spencer 1154bb6b43 Adjust long file name writing to match BSD 4.4 and Mac OSX style archives. 
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.

llvm-svn: 17909
 2004-11-17 16:13:11 +00:00
Reid Spencer 4c66d89b33 Fix typeo in comment.

 2004-11-16 06:47:30 +00:00
Reid Spencer 4abd79e8ea Per code review:\ 
* Make sure we write out the foreign symbol table if we read one \
* Make the padding calculation more efficiently and avoid Solaris warnings

llvm-svn: 17883

llvm-svn: 17876
 2004-11-16 06:41:05 +00:00
Chris Lattner 3b6bb48c16 Do not emit FunctionBlock blocks for external functions. This shrinks 
bytecode files by about 8 bytes per external function

llvm-svn: 17859
 2004-11-15 22:39:49 +00:00
Chris Lattner 642f8c5ed4 Use a per-function flag bit to indicate whether or not there is a function 
body for the function.

llvm-svn: 17858
 2004-11-15 22:38:52 +00:00
Chris Lattner 9b457e1c73 Disable this change, it was premature 
llvm-svn: 17857
 2004-11-15 21:56:33 +00:00
Chris Lattner 7d04cdab77 Make *SURE* to null out the pointer before throwing an exception, otherwise 
the dtor for the BytecodeReader class will try to free it again!

llvm-svn: 17856
 2004-11-15 21:55:33 +00:00
Chris Lattner 36c95e38b0 Cleanups. Null out pointer after freeing it for paranoia 
llvm-svn: 17855
 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.
