[llvm-dev] Two FPPassManager objects, and LocalStackSlotAllocation::runOnMachineFunction returns true but has not changed the data

[JD Jones via llvm-dev]

Good Morning, all,

 

I stumbled across a couple of curious things in the LLVM code.  I'm too new
to this to know whether these are functioning correctly or not.  Guidance
would be appreciated.

 

Perhaps it is something I have done wrong, but my executions of llc are
creating two FPPassManager objects (that run different sets of passes).
FPPassManager contains a static char ID (as expected), so I expected only
one FPPassManager object to be constructed during a single execution.

 

And LocalStackSlotAllocation::runOnMachineFunction returns true even when it
has not changed the data (in any way that I can see).  

 

 

Many Thanks,

JD Jones
