Reid Spencer 709e10ed92 Implement an isBytecodeArchive method to determine if an archive contains 
bytecode file members or not.

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.

Reid Spencer fc9f779039 Don't save an iterator, just use post-increment.

 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.

 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)"

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.

symbol table.
* Make sure we update the file pointer for each member when rebuilding the
  symbol table.

Reid Spencer 0cc653e59b First kinda/sorta working version of the Archive library. Reading is not 
yet supported but writing works. Way too early to review this. More to come
