few days.  Apparently the old symbol table used to auto rename collisions in
the type symbol table and the new one does not.  It doesn't really make sense
for the new one to do so, so we just make the client do it.

Don't use size() when you mean empty()

Minor efficiency gain: do 1 nlogn lookup instead of two
Code cleanup

Minor changes.  Switch to a SymbolTable remove that does not take linear time

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13874 91177308-0d34-0410-b5e6-96231b3b80d8

Eliminate this form of SymbolTable::remove.  It ignores the type argument
anyway.  Add a form that takes a type_iterator for the C backend.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13873 91177308-0d34-0410-b5e6-96231b3b80d8

Fix one of the major things that is causing the C Backend to infinite loop

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13872 91177308-0d34-0410-b5e6-96231b3b80d8

Add support for getting executable memory on Windows.  This is actually
much easier than on unix.  :)  The only evil thing is that windows.h defines
a macro named FindExecutable, which collides with one of our names.

The JIT now runs on windows, but it cannot resolve external functions
(like printf) yet.

Add a new function for the JIT.  libsupport is now the only library that
includes mman.h

Use the SystemUtils.h file to do our dirty work.

Right: the #includes are not needed either

Add support for zero length files

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13866 91177308-0d34-0410-b5e6-96231b3b80d8

Use fileutilities instead of mmap directly

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13865 91177308-0d34-0410-b5e6-96231b3b80d8

Use the new FileUtilities.h API for mapping a file into an address
space

Add a pair of functions to hide system specific details of mapping a file in for reading.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13863 91177308-0d34-0410-b5e6-96231b3b80d8

Remove some more dead code resulting from adding setTypeName().

Remove an assertion that uses Type::TypeTy that is never hit and will
break when Type::TypeTy goes away. Also remove a dead block of code and
dead comments.

Clean up a comment.

Fix for bug 348.
The SymbolTable changes caused this one too.
