question on analyzeBranch and getFallThrough
I am working on a back end for an architecture whose jump via table instruction
includes the range check. If the index is out of range, the jump table
instruction just falls through. I implemented a pass to remove the range check
generated before the jump table instruction because it is superfluous.
This causes as assertion in MachineBlockPlacement.cpp:

Regarding basic block layout/code placement optimizations of profile guided optimization (PGO)
Hi,
I would like to learn the details regarding what exactly PGO does for basic
block layout/code placement optimizations in llvm. Could you please point
me to some descriptions? Is it close to this paper (Karl Pettis and Robert
C. Hansen. 1990. Profile guided code positioning. PLDI'90)
http://perso.ensta-paristech.fr/~bmonsuez/Cours/B6-4/Articles/papers15.pdf?

Thanks, Chandler. This is great stuff.

[LLVMdev] How do you add MachineBlockPlacement to a Function Pass Manager?
I'm trying to port llvm-lua so it's buildable with llvm trunk. A problem I'm
running into is that it uses the older BlockPlacement pass. From searching
around and reading llvm's commit, this pass has been replaced and superseded
by Chandler's MachineBlockPlacement pass.
What's unclear to me is how exactly do you add this pass to say a function
pass manager?

Fileserver advice needed
I have a domain with two Samba DC's
I don't want to use either of them as a fileserver, so I want to build a
separate file server which is not a DC, which will deliver all the files to
the lovely little windows users (including their roaming profiles).
I've been looking online and there seems to be a thousand different ways to
"join" my fileserver to the domain, but most of

[LLVMdev] How basic block layout is determined during scheduling?
Hi, guys,
I compiled a subroutine with -O2, and llvm backend produced codes like:

R31 = -1
R20 = R31 * R20;
....
bnz R2, LBB0_34

[RFC] Control Flow Sensitive AutoFDO (FS-AFDO)
Hi all,
Here I include an RFC for control flow sensitive AutoFDO (FS-AFDO). This is
a joint work with David Li. Questions and feedback are welcome.
