[LLVMdev] Running a pass
...need a
PassInfo object, using which we create a new pass object.
I tried the following code (which I wrote after looking at
the code for bugpoint), but the list of passes seems to be
empty:
// Create a list of all the registered passses
static cl::list<const PassInfo*, bool, PassNameParser>
PassList(cl::desc("Passes available:"), cl::ZeroOrMore);
mem2reg_pass = NULL;
for(It i = PassList.begin(); i != PassList.end(); i++) {
std::cout << (*i)->getPassName() << endl;
if(string("mem2reg") == (*i)->getPassName()) {
mem2reg_pass = *i;
break;...

[LLVMdev] Any way to use a pass in opt, that does not have normal constructor?
Dear LLVM,
The TargetData pass needs target data layout to be specified in
constructor, and therefore its normal ctor is defined, but always
gives a fatal error.
Still, is there any way to make it loadable into the opt tool? I need
this to make use of bugpoint in reducing backend test case.
Thanks,
- Dima.

[LLVMdev] Choosing Alias Analysis
Ok, here's a potentialy stupid question: how do I choose the various flavors
of alias analysis on the command line? I followed the alias analysis design
in its use of AnalysisGroup when I did the register coalescing refactoring and
alternative implentations. But I can't figure out how to actually invoke the
different versions. There's no cl_opt for the various alias analysis flavors

Following uses basic alias analysis
$ opt -licm foo.bc -disable-output -debug-pass=Structure
where as
$ opt -anders-aa -licm foo.bc -disable-output -debug-pass=Structure
uses Andersens analysis algorithm implementation.

[LLVMdev] Choosing Alias Analysis
...a particularly bad choice for an example on my part. It has
special code to provide options for all of the optimizations:
// The OptimizationList is automatically populated with registered Passes by
// the PassNameParser.
//
static cl::list<const PassInfo*, bool, PassNameParser>
PassList(cl::desc("Optimizations available:"));
A better question to ask is, how do I do this with llvm-gcc? My perusal of
the code doesn't turn up any obvious places for options for alias analysis
are registered.

"Available" as referenced by PassSupport.h:
