[LLVMdev] alias analysis in backend
Hi Hal,
Thanks. How about a symbol with two different immediate offsets - the Value* would be the same, right? I don't see how AliasAnalysis::Location would handle this... And BasicAliasAnalysis does
if (V1 == V2) return MustAlias;
, so I'm not sure how this would be done .. ?

[LLVMdev] Aliasing bug or feature?
Hello everyone,
I am working on some changes to the Hexagon VLIW PreRA scheduler, and as a
part of it need to test aliasing properties of two instruction.
What it boils down to is the following code:
char a[20];
char s;
char *p, *q; // p == &a[0]; q == &s;
void test()
{
register char reg;
s = 0;
reg = p[0] + p[1];
s = q[0] + reg;
return;
}

[buildSchedGraph] memory dependencies
Hi,
(This only concerns MISNeedChainEdge(), and is separate from D8705)
I found out that the MIScheduler (pre-ra) could not handle a simple test
case (test/CodeGen/SystemZ/alias-01.ll), with 16 independent load / add
/ stores.
The buildSchedGraph() put too many edges between memory accesses, because
1) There was no implementation of areMemAccessesTriviallyDisjoint() for
SystemZ.

Question about physical registers in ISel
Hi all,
I need to figure out why InstrEmitter::EmitMachineNode assumes that when
the number of outputs of a MachineSDNode is greater than the number of defs
in the corresponding MCInstrDesc, the outputs in the difference will be
placed into physical registers as opposed to virtual registers.
The specific line in question is:
bool HasPhysRegOuts = NumResults > NumDefs &&

ISelDAGToDAG breaks node ordering
Hi,
During instruction selection, I have the following code for certain LOAD
instructions:
const LoadSDNode *LD = cast<LoadSDNode>(N);
SDNode* LDW = CurDAG->getMachineNode(AVR::LDWRdPtr, SDLoc(N), VT,
PtrVT, MVT::Other,
LD->getBasePtr(), LD->getChain());
// Honestly, I have no idea what this does, but other memory

Question about physical registers in ISel
Hi Quentin,
Thanks, that explanation makes sense. I can see that in a normal register
machine, implicitly defs must be physical registers. In a stack machine
like WebAssembly, though, implicit defs are known to be pushed onto the
value stack just like any other defs. Slots on the value stack are
represented by virtual registers until stackification, so for WebAssembly
we do need the implicit defs

Question about physical registers in ISel
To get into more detail, I'm trying to update WebAssembly's `call`
instruction. `call` is currently constrained to return one or zero
arguments, so in TableGen we have a separate call Instruction for each
possible return type. But I need to update calls to return arbitrarily many
values of any combination of WebAssembly types, so even if we imposed some
reasonable artificial limit like 8

[LLVMdev] R600/SI build failure on Leopard (Use of C++11)
Hi Christian,
Ryan just reported to me that llvm-3.4 is no longer building on OS X Leopard (https://trac.macports.org/ticket/41548). It seems the issue is with a commit that you made back in April (referenced below) which added this to SIISelLowering.cpp:
// Adjust the writemask in the node
std::vector<SDValue> Ops;
Ops.push_back(DAG.getTargetConstant(NewDmask, MVT::i32));

Can you elaborate on the fix you are thinking of? I'm not sure what you're

[LLVMdev] BR_CC questions
I am implementing a new backend and am pretty sure I don't quite understand "the way" one is supposed to implement conditional branches.
My target CPU natively supports a conditional branch instruction that accepts a condition to test (equal, less than, etc.), two operands (two registers, or one register and one immediate), and finally a target PC to branch to if the comparison

Can winbind solve this problem...
>From a linux box, I mount a native NT share (mount -t smbfs -o<options,
etc. etc>).
I want to be able to do an 'ls -l' in that share and have the
owner/group information show the right thing. Currently, no matter what
the ACLs on the file on the NT side, from linux, an 'ls -l' shows 'root'
as the owner/group.
I was expecting winbind to work similar to ypbind in

NO ACTIVE CONNECTIONS
can anyone pls help,
On my Windows server, I can view and access my Samba
Server and shares, but on my Samba Server under Server
Status, the ACTIVE CONNECTIONS shows no value even
while the "demons" are running.
Sometimes The Active Conections displays 0.0.0 for the
value of the IP address.
This is absolutely driving me nuts.
SOMEONE PLS HELP!!!!
