You can't have implicit defs that overlap explicit defs, or implicit
defs that alias one another.

by splicing function bodies from the src module to the destination module.

This speeds up linking quite a bit, e.g. gccld time on 176.gcc from 26s -> 20s
when forming the .rbc file, with a profile build.  One of the really strange
but cool effects of this patch is that it speeds up the optimizers as well,
from 12s -> 10.7s, presumably because of better locality???

In any case, this is just a first step.  We can trivially get rid of the
LocalMap now and do other simplifications.

* Adjust indentation\
* Ensure memory do not leak if exceptions happen (std::auto_ptr use)

llvm-svn: 17885

* Make the numVbrBytes function more efficient and better documented \
* 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 \
* Make sure foreign symbol tables are written

llvm-svn: 17884

* 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

* Make sure all members are initialized upon construction

llvm-svn: 17882

llvm-svn: 17880

* Get rid of memory leaks on exception \
* Provide better comments of how the memory handling works

llvm-svn: 17876

llvm-svn: 17875

* get rid of (void) construct in function declarations
* make toString a const member
* add a default implementation of toString for Win32

llvm-svn: 17873

* Clean up the StatusInfo constructor to construct all members and give
  them reasonable values.
* Get rid of the Vector typedef and make the interface to
  getDirectoryContent use a std::set instead of a std::vector so the dir
  content is sorted.
* Make the getStatusInfo method const and not return a useless boolean.

*Implement/Document the cl::extrahelp feature instead of the MoreHelp ptr.

already been emitted, we don't have to remember it and deal with it later,
just emit it directly.

llvm-svn: 17868

* Get rid of "emitMaybePCRelativeValue", either we want to emit a PC relative
  value or not: drop the maybe BS.  As it turns out, the only places where
  the bool was a variable coming in, the bool was a dynamic constant.

immediately instead of lazily.

In this program, for example:

int main() {
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
}

We used to have to go through compilation callback 4 times (once for each
call to printf), now we don't go to it at all.

Thanks to Misha for noticing this, and for adding the initial ghost linkage
patches.
