I found a bug in the expansion code for SUB going back to at least LLVM 2.6 and still shows up in trunk. case ISD::SUB: { EVT VT = Node->getValueType(0); assert(TLI.isOperationLegalOrCustom(ISD::ADD, VT) && TLI.isOperationLegalOrCustom(ISD::XOR, VT) && "Don't know how to expand this subtraction!"); Tmp1 = DAG.getNode(ISD::XOR, dl,

Hi, for some temporary debugging I wanted to know what sort of Value I was seeing, and I ran across this comment in Value.h - it's probably a minor point, but unless I'm missing something I think either the last line of the comment is wrong or the code is. It appears in rev 1.58, as part of fixing bug 122. 00134 /// getValueType - Return an ID for the concrete type of this object.

I've been playing around with spillers and found that the SimpleSpiller fails badly on a particular code. The problem arises because SimpleSpiller does the test VRM.isAssignedReg(virtReg) which is implemented as: 00183 bool isAssignedReg(unsigned virtReg) const { 00184 if (getStackSlot(virtReg) == NO_STACK_SLOT && 00185 getReMatId(virtReg) == NO_STACK_SLOT)

Does anybody else have an opinion on this issue? I'm planning to submit a patch which would add a new get method for ConstantDataVector taking an ArrayRef<Constant*> and use that in the few places in constant propagation where convertToFloat is used. Let me know if you think there is a more obvious way to do it. Right now the only way to create a ConstantDataVector are those method:

I don't see a way to create a ConstantDataVector from Constant or form APFloat though. Did I oversee that? Is the solution to had a new get function in ConstantDataVector to allow that? Any hint on what would be the right fix otherwise?

Ok, I am really stumped on this one. I setup ipfw with all my rules. Everything works great except for dns. If I do nslookup I get -su-2.05b# nslookup yahoo.com Server: localhost.webspacesolutions.com Address: 127.0.0.1 *** localhost.webspacesolutions.com can't find yahoo.com: Non-existent host/domain This is what I have in my ipfw.rules add 00310 allow tcp from any to any 53 out via

Fantastic! It's working! Thank you so much Craig!!! On Fri, Apr 7, 2017 at 6:05 PM, Craig Topper <craig.topper at gmail.com> wrote: > It should be VectorType::get(Type::getInt32Ty(Context),4).

If someone has some free time, can you go over my ipfw config. See if I have any problems, or things i should add. Im not an ipfw expert or anything. Here is the config. add 100 allow all from any to any via lo0 add 110 deny log all from any to 127.0.0.0/8 add 120 deny log ip from 127.0.0.0/8 to any add 00200 check-state add 00250 deny all from any to any frag in via bge0 add 00260 deny

I am having some problems getting TelIax service to work with *. Outbound calls work just fine. When I try an inbound call the phone rings and there is no audio.

Does anyone have an idea what could be causing the codecs to
