Suppose the TokenFactor can reach the Op:
[Load chain]
^
|
[Load]
^ ^
| |
/ \-
/ |
/ [Op]
/ ^ ^
| .. |
| / |
[TokenFactor] |
^ |
| |
\ /
\ /
[Store]
If we move the Load below the TokenFactor, we would have created a cycle in
the DAG.

I've been told apple gcc version number is not guaranteed to increase
monotonically. Change the preprocess condition to make it less risky.
The configuration change is done during the middle 10.4 life cycle so we have
to check __APPLE_CC. For future OS X release, we should be able to assume
-fenable-cxa-atexit is the default.

Make the ProgramName variable a std::string so we can eliminate the path
...
portion fo the program name via sys::Path().getLast(). This makes error
messages more readable since this is invariably used only in error
messages. Instead of:
/path/to/llvm/bin/directory/toolname: error message
we will now get:
toolname: error message
Also, since we always have a program name (even if its defaulted), don't
check to see if it is set or not when generating error messages. This
eliminates a bunch of constant strings, saving a little under 1K of data.

1. Actually turn on -fno-exceptions in libraries that do not have the

savings were made (DEBUG):
libLLVMDataStructure.a 525K
libLLVMCore.a 380K
libLLVMCodeGen.a 350K
libLLVMTransformUtils.a 305K
libLLVMScalarOpts.a 270K
libLLVMAnalysis.a 247K
libLLVMSelectionDAG.a 233K
libLLVMipo.a 175K
LLVMX86.o 123K
LLVMPPC.o 81K
libLLVMipa.a 17K
TOTAL 2,706K
Note that the savings is actually a little larger than this because
I didn't count any of the libraries that had small changes.
2. Remove REQUIRES_EH from the AsmParser library as it is now exception
free. This resulted in a nearly 78K drop in the size of the debug
library for AsmParser.

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.

Reimplement the loopsimplify code which deletes edges from unreachable

blocks that target loop blocks.
Before, the code was run once per loop, and depended on the number of
predecessors each block in the loop had. Unfortunately, scanning preds can
be really slow when huge numbers of phis exist or when phis with huge numbers
of inputs exist.
Now, the code is run once per function and scans successors instead of preds,
which is far faster. In addition, the new code is simpler and is goto free,
woo.
This change speeds up a nasty testcase Duraid provided me from taking hours to
taking ~72s with a debug build. The functionality this implements is already
tested in the testsuite as Transforms/CodeExtractor/2004-03-13-LoopExtractorCrash.ll.

Start eliminating temporary vectors used to create DAG nodes. Instead, pass
...
in the start of an array and a count of operands where applicable. In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap. In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.
I updated a lot of code calling getNode that takes a vector, but ran out of
time. The rest of the code should be updated, and these methods should be
removed.
We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.
It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

different combinations of Text/Weak Weak/Text and Text/Text linking

For PR780:
...
1. Change the usage of LOADABLE_MODULE so that it implies all the things
necessary to make a loadable module. This reduces the user's burdern to
get a loadable module correctly built.
2. Document the usage of LOADABLE_MODULE in the MakefileGuide
3. Adjust the makefile for lib/Transforms/Hello to use the new specification
for building loadable modules
4. Adjust the sample project to not attempt to build a shared library for
its little library. This was just wasteful and not instructive at all.

Make the removal of files use Path::eraseFromDisk just like it does for

the removal of directories. Using std::remove is indiscriminate and can
lead to the removal of things like /dev/null if run as root. The
Path::eraseFromDisk method ensures that we only ever remove regular files
or directories, but never character or block special nodes. This should
clear up the problem with usage like: llvm-as -o /dev/null which is used
in the llvm-test makefiles.

1. Update an obsolete comment.
2. Make the sorting by base an explicit (though still N^2) step, so
that the code is more clear on what it is doing.
3. Partition uses so that uses inside the loop are handled before uses
outside the loop.
Note that none of these changes currently changes the code inserted by LSR,
but they are a stepping stone to getting there.

Replace the SSA update code in LCSSA with a bottom-up approach instead of a top
...
down approach, inspired by discussions with Tanya.
This approach is significantly faster, because it does not need dominator
frontiers and it does not insert extraneous unused PHI nodes. For example, on
252.eon, in a release-asserts build, this speeds up LCSSA (which is the slowest
pass in gccas) from 9.14s to 0.74s on my G5. This code is also slightly smaller
and significantly simpler than the old code.
Amusingly, in a normal Release build (which includes the
"assert(L->isLCSSAForm());" assertion), asserting that the result of LCSSA
is in LCSSA form is actually slower than the LCSSA transformation pass
itself on 252.eon. I will see if Loop::isLCSSAForm can be sped up next.

- Refactor the code that resolve basic block references to a TargetJITInfo
...
method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
of code is emitted to flush the icache. This ensures correct execution
on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.
