With this, bugpoint can reduce the 176.gcc failure.

miscompilation. This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.

This patch converts the old SHR instruction into two instructions,
AShr (Arithmetic) and LShr (Logical). The Shr instructions now are not
dependent on the sign of their operands.

Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

it clones the module for each pass. An obvious improvement is not to do that.

DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

This pass:
1. Splits TargetMachine into TargetMachine (generic targets, can be implemented
any way, like the CBE) and LLVMTargetMachine (subclass of TM that is used by
things using libcodegen and other support).
2. Instead of having each target fully populate the passmgr for file or JIT
output, move all this to common code, and give targets hooks they can
implement.
3. Commonalize the target population stuff between file emission and JIT
emission.
4. All (native code) codegen stuff now happens in a FunctionPassManager, which
paves the way for "fast -O0" stuff in the CFE later, and now LLC could
lazily stream .bc files from disk to use less memory.
5. There are now many fewer #includes and the targets don't depend on the
scalar xforms or libanalysis anymore (but codegen does).
6. Changing common code generator pass ordering stuff no longer requires
touching all targets.
7. The JIT now has the option of "-fast" codegen or normal optimized codegen,
which is now orthogonal to the fact that JIT'ing is being done.

virtual functions in LLVM. The -Woverloaded-virtual option is now turned on.

memory pressure. This order spaces out large executables with small ones in
between so that in a -j2 or -j3 build, it only attempts to build only one
large executable at time. If you're doing -j4, you probably have enuogh
memory anyway.

Adjust usage of the ExecuteAndWait function to use the last argument which
is the ErrMsg string. This is necessitated because this function no longer
throws exceptions on error.

one-off (and broken) RunOptimizations function. Also, run some cleanup

any cruft left around by thos passes.
This patch was inspired by a patch submitted by Bram Adams.

Rid the Assembly Parser of exceptions. This is a really gross hack but it
will do until the Assembly Parser is re-written as a recursive descent.
The basic premise is that wherever the old "ThrowException" function was
called (new name: GenerateError) we set a flag (TriggerError). Every
production checks that flag and calls YYERROR if it is set. Additionally,
each call to ThrowException in the grammar is replaced with GEN_ERROR
which calls GenerateError and then YYERROR immediately. This prevents
the remaining production from continuing after an error condition.

Shrinkify LLVM's footprint by removing the analyze tool and moving its
functionality into the opt tool. THis eliminates one of the largest tools
from LLVM and doesn't make opt much bigger because it already included
most of the analysis passes. To get the old analyze functionality pass
the -analyze option to opt. Note that the integeration here is dead
simple. The "main" of analyze was just copied to opt and invoked if the
-analyze option was given. There may be opportunities for further
integration such as removing the distinction between transform passes
and analysis passes.
To use the analysis functionality, if you previously did this:
analyze $FNAME -domset -disable-verify
you would now do this:
opt -analyze $FNAME -domset -disable-verify
Pretty simple.

Enable the makefile check on the result of find-cycles.pl. LLVM is now
cycle free and we intend to keep it that way. This patch will fail the
build if cycles are found.

instead of throwing an exception. This reduces the amount of code that is
exposed to exceptions (e.g. FileUtilities), though it is clearly only one step
along the way.

This is faster because SplitFunctionsOutOfModule no longer calls Clone Module and then removes the functions it doesnt want from the module returned. Instead it creates a module and copies over the specified functions, making changes to the new and old module where neccessary. This reduces the memory demand.

have a compile-host version of "nm", not build-host. In order to effect this
we must use autoconf to determine the correct "nm" to use and propagate that
through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.

that equals the number of cycles found. The Makefile was changed to ignore
the status code of find-cycles.pl. This should be removed once the libraries

2. Make Mangler.h and InlineAsm.h use the macros to ensure linkage

1. llvm is built with objroot = OBJ and installed.
2. OBJ is deleted or install tree is shipped.
3. llvm-config is run.
In this scenario, llvm-config shouldn't emit an error message at #3, it
should just know it's not running in the objdir :)

1. If Perl is not available, don't run Perl dependent targets.
2. Check in FinalLibDeps.txt for build environments that can't build it
because there's no Perl processor.
3. Ensure that FinalLibDeps.txt depends on LibDeps.txt so it is
automatically regenerated.
4. Support objdir != srcdir building.

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
