[LLVMdev] About writing an alias analysis pass for LLVM 3.1
Hi,
I am now trying to write an alias analysis pass for LLVM 3.1. The pass
is compiled into a .so library. When I loaded it into opt to perform
evaluation with command:
opt -load my-so-lib -aa-eval foo.bc
the following errors occurred:
opt: raw_ostream.cpp:261: void llvm::raw_ostream::flush_nonempty():
Assertion `OutBufCur > OutBufStart && "Invalid call to flush_nonempty."'
failed.
As stated in the documentation I found on LLVM official website, an
alias analysis pass should subclass both Passand AliasAnalysisclass. I
used GDB for some debugging, and found why the...

[LLVMdev] SmallString + raw_svector_ostream combination should be more efficient
I don't think we should make flush virtual. Why do you need to do it?
Can't you set up the base class to write to use the tail of the memory
region as the buffer?

[LLVMdev] SmallString + raw_svector_ostream combination should be more efficient
Could you dig into why:
+ raw_ostream &write(unsigned char C) override {
+ grow(1);
+ *OutBufCur++ = C;
+ return *this;
+ }
Is 3 times as fast as raw_svector_ostream? I don't see a good reason why
that should be any faster than:
raw_ostream &operator<<(char C) {
if (OutBufCur >= OutBufEnd)
return write(C);
*OutBufCur++ = C;
return *this;
}

[LLVMdev] SmallString + raw_svector_ostream combination should be more efficient
Sean, thanks for reminding this, Alp did commit a class derived from
raw_svector_ostream conatining an internal SmallString he called
small_string_ostream.
The commit was reverted after a day due to a disagreement about the commit
approval and apparently abandoned.
