Added the -native option.
With this option, gccld links the program into LLVM bytecode and a native code
binary.  This allows llvmgcc to correctly tell GNU configure scripts when
things aren't defined properly (because the native link will fail).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8570 91177308-0d34-0410-b5e6-96231b3b80d8

Updated the name of the linker to llvm-link.
This should fix the MultiSource tests.

Fix bug raising allocations whose call sites were invoke instructions.
Thanks to brg for tracking down the problem so precisely!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8568 91177308-0d34-0410-b5e6-96231b3b80d8

This is effectively a complete rewrite of the globaldce algorithm, resulting
in it being both shorter and more effective.  It no longer depends on the
callgraph, so one FIXME has been fixed.

Additionally, this pass was not able to delete recursive (but dead) functions
if they were pointed to by global variables which were also dead.  In fact
this pass had a lot of problems deleting functions which were only pointed
to by dead globals and other stuff.

Fixing this means that the entire EH library should be stripped away now from
programs that don't use sjlj or exceptions.

`link' is now `llvm-link'. Also alphabetized the tools for easy reference.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8557 91177308-0d34-0410-b5e6-96231b3b80d8

Allow multiple object trees to use the source tree tests at once by
using a QMTEST_CLASS_PATH local to the object tree.
Add the gui target to start the QMTest gui (saves writing a few lines of
documentation too). :)

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8552 91177308-0d34-0410-b5e6-96231b3b80d8

Have the configure script put llvm.py into the object root.
The QMTest program can then use that as the location for loading test and
resource class, thus compiling the Python code into the object root as
desired.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8551 91177308-0d34-0410-b5e6-96231b3b80d8

Put llvm .bc files into the BytecodeObj subdirectory instead of the Bytecode
subdirectory.  This prevents the 'make clean' rule from removing lib/Bytecode

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8550 91177308-0d34-0410-b5e6-96231b3b80d8

QMTest test and resource classes are always register before running the tests.
This ensures that any python bytecode generated by another platform is
replaced with new pythong bytecode before the tests begin.

Perferably, a better method will be implemented in the next few weeks.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8549 91177308-0d34-0410-b5e6-96231b3b80d8

Modified the checks slightly so that one can re-configure LLVM without

Added code that verifies that the source directory has not been configured
already.  This should help prevent strange errors from happening, but will
make re-configuring the source directory more difficult when it is shared with
the object directory.

Update makellvm to work with the brave new world of separate obj-root trees.
With these changes, you can still run makellvm directly from your source tree

or
  % makellvm -obj obj-root [toolname] ## specify obj-root explicitly.

With the first from, `makellvm' checks the following places in order
and uses the first one that contains the file `Makefile.config':
(1) Your src-root directory

Modified the footer to be a link to the LLVM web page.
Organized the commands into three distinct groups on the main page.
Fixed the hyperlinks in the main page.
Removed as and dis; they will not exist with those names by Release 1.

Adding a skeleton for the LLVM Command Guide.
Hopefully the group as a whole will update this into a real guide.

Fixed spelling and grammar.

Fixed SPEC so that it would run correctly with the new autoconf-style object
directory.
Cleaned up the Makefile so that it uses VPATH to find source files.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8477 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed SPEC so that it would run correctly with the new autoconf-style object
directory.
Added Makefile.spec to the list of files to copy to the object directory.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8476 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed SPEC so that it would run correctly with the new autoconf-style object
directory.
Added Makefile.spec to the list of files to copy to the object directory.
Moved the configuration of $SourceDir to Makefile.config and corrected the
conditional that surrounds it.  This allows SPEC to reset it and get the correct
VPATH.

scalarrepl now includes mem2reg

Integrate functionality of the mem2reg pass directly into this pass to make
the combination more effective

Move the -indvars pass much later to where it is more likely to do good stuff

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8470 91177308-0d34-0410-b5e6-96231b3b80d8

Renamed DominatorTree::Node::getNode() -> getBlock()

Get rid of the whole "Node2" business, rename getNode() ->getBlock() to
be more descriptive

Spell `definite' correctly.

Removed the aposthrophes endings and the elipses suffixes from build output.
This makes the output more consistent, and I just find aposthrophes annoying.
:)

Check in the fix I meant to apply here, but mistakenly applied to
tools/extract instead..... heh

* Move include files from middle of file to the top where they belong, moving
  the #define up there too
* Since we're including system headers, use the ones in include/llvm/Config
* While we're here, use the canonical LLVM header ordering algorithm

Unwind instructions are intrinsically alive, just like returns
