I have a dataframe zeespan. One of the columns has the name "customer". The data in the customer column is text. I would like to return a subset of the dataframe with all rows that DON'T begin with either "ibm" or "exxon", or "sears" in the customer column. I tried .... subset(zeespan, customer != c("ibm" | "exxon" | "sears") ) That didn't work and even if it did, the text would have to be an exact match where what I really want is "begins with". Suggestions on how to do th...

Is that even a valid instruction? I thought TEST only took 32-bit immediates.

Yeah, the alternative is to do movabs and then test, which is doable but I’m not sure if it’s worth it (surely BT + risk of flags merging penalty has to be better than two ops, one of which is ~9-10 bytes).

...on a remote server. I would like the local dataframe have the same name as the source SAS dataset, and the function below is what I am developing. However, the "substitute(table)" on the left side of the assignment generates the error "Error in substitute(table) <<- sqlQuery(sears, sql.stmt) : could not find function "substitute<-".

I'm tracking down an X86 code generation malfeasance regarding BT (bit test) and I have some questions. This IR *matches* and then *X86TargetLowering::LowerToBT **is called:* %and = and i64 %shl, %val * ; (val & (1 << index)) != 0 ; *bit test with a *register* index This IR *does not match* and so *X86TargetLowering::LowerToBT **is not called:* %and = lshr i64 %val, 25

I'd like to store a tablegen generated enumeration in a record field/value. Clearly this enumeration isn't available yet so it seems that a code fragment should be the escape mechanism I need. Looking at the other backends for examples, I see things like [{ return Imm >= 0 && Imm < 64; }] // promising code Requires = [{ {} }];

Is this just something I have to live with using NuFOne, or did I miss some type of config in * that will grab the callerID other than the inbound 866 number...?

Hi Chris, If you have everything setup to test, can you generate the LLVM IR with -03 from 3.4.1 and 3.5 to be sure they match. Then we can focus on the backend.

This is a patch to X86TargetLowering::LowerToBT() which was hashed over on the Developers list with Intel concurring. It checks whether the -Oz (optimize for size) flag is set or whether the containing function's PGO cold attribute is set. If either are true it emits BT for tests of bits 8-31 instead of TEST. Previously, TEST was always used for bits 0-31 and BT was always used for bits
