Yes, it is so. What you can find on llvm.org is the latest. If you
need something new - try clang or dragonegg.

No, -basicaa is added

[LLVMdev] how to choose which alias analysis used in my pass?
Hi,
I want to use memory dependence analysis in my pass, but I feel the
default alias analysis is not precise enough. How could I choose to use
another alias analysis algorithm? I have tried opt -load mypass.so
-basicaa xx.bc > /dev/null. But I feel the alias analysis algorithm does
not change. Do I need to add something in my codes?
Thanks a lot!

[LLVMdev] Could I explicitly tell clang not inline some functions?
Hi,
I am wondering whether there are some ways I can tell clang not
inline some or all functions.
Thanks a lot!

[LLVMdev] how to identify basic blocks added for switch instruction without default?
Hi,
I just notice that front-end will add an extra block for switch
instruction without default. How could I identify basic blocks added due
to this reason?
The added codes looks like:
sw.default.i625: ; preds = %if.end512
tail call void @fancy_abort(i8* getelementptr inbounds ([38 x i8]*
@.str, i64 0, i64 0), i32 3045, i8* getelementptr inbounds

[LLVMdev] How to get the name and argument of a function
Thanks a lot!
I finally fix my problem.
My code is like this:
//CallInst* pCall pCall is a printf called in my situation
if( ConstantExpr * pCE = dyn_cast<ConstantExpr>( pCall->getArgOperand(0))){
if( GlobalVariable * pGV = dyn_cast<GlobalVariable>( pCE->getOperand(0))){

[LLVMdev] Compile error of latest Dragonegg on Ubuntu with GCC 4.5

When I tried to compile Dragonegg using the SVN trunk code,
I encountered failure with error message:

[LLVMdev] How to get the name and argument of a function
Hi everyone:
The code I am analyzing is :
int main()
{
int i = 0;
printf("hello world!");
printf( "%d" , i );
}
I want to get each place where printf is called, and the argument used
during that call.
so I write llvm pass code like:
void Myfunction( Function & F){
for( Function::iterator b = F.begin() , be = F.end() ;

[LLVMdev] question about licm
hi,
I applied licm with basicaa on the following codes:
int j = atoi(argc[1]);
int lower[] = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1};
int upper[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
for(i = lower[j]; a[i] < 100 && i < upper[j]; i ++);
I notice that upper[j] is not hoisted out from the loop. Is this
because j could be larger than 10?
Thanks a lot!

Do you have MPFR installed?

Yest. thanks. I just resolved this error by installing MPFR, MPC and GMP(by
the way, these are not listed
as prerequisites in the website.). But other errors come:

Hi:
My llvm code is:
for( BasicBlock::iterator i = b->begin() , ie = b->end();
b != be ; b ++ ){
if( CallInst * pCall = dyn_cast<CallInst>(i)){
pCall->dump(); //
Function * pFunction = pCall->getCalledFunction();
if( !pFunction ){
}
std::string fname = pFunction->getName();
}
}
The dump result
