In our generated asm code we've got a constraint such that two registers in a ternary op have to be in different "banks", best illustrated with an example: add r1,r2,r1 # r1 <- r2 + r1 The problem here is that the first operand (the receiver of the value) is in the same "bank" as the 3rd operand (r1 again). This will cause an extra cycle to be burned. As it turns out the first and second operands can be in the same bank, so the issue is with th...

Thanks a lot, Ista! I really appreciate it. How about a slightly different case as the following: set.seed(1) (tmp <- data.frame(x = 1:10, R1 = sample(LETTERS[1:5], 10, replace = TRUE), R2 = sample(LETTERS[2:6], 10, replace = TRUE))) x R1 R2 1 C B 2 B B 3 C E 4 E C 5 E B 6 D E 7 E E 8 D F 9 C D 10 A E Notice that the factor levels between the two factors, R1 and R2, slide by one leve...

I have two data frames. Suppose the first has rows r1 r2 r3 and the second has rows R1 R2 R3 I'd like to generate the data frame: r1 R1 r1 R2 r1 R3 r2 R1 r2 R2 r2 R3 r3 R1 r3 R2 r3 R3 How would I go about doing this? I'm sure there's a clean way to do it but I find myself thinking...

...-fPIE. In that case we've designated some registers to be pointers to various address spaces (and our processor is rather complicated so there are several address spaces). Right now, given a global variable called 'answer' in C we end up with the following in the .s file: movimm r1, %rel(answer) # r1 <- offset to 'answer' symbol load r1, r1, 0 # r1<-mem[r1+0] This isn't correct because it should be relative to the GRP register if the PIE mode is chosen, what I'd like to get is either: movimm r1, %rel(answer) addI...

Untested, but I expect that setting the levels to be the same across the two factors levels(tmp$R1) <- levels(tmp$R2) <- LETTERS[1:6] and proceeding as before should be fine.

Hi Reed, the register scavenger (RS) also keeps track of live registers. This way it "knows" that the register that was spilled/restored far apart is available. Let say you had the following code. You need to find a register to keep vreg1 and vreg2 in. R1 = .... // <- RS current liveness state; we have called RS->forward(It) where It points to here vreg1 = add SP, 1000 ... = load vreg1 ... // more code vreg2 = add SP, 2000 ... = load vreg ... = R1 When you come to the definition of vreg1 you (or lets say the scavengeFrameVirtualRegs function...

Hi, I have a matrix with column names starting with a character in [0-9]. After some matrix operations (e.g. copy to another matrix), R seems to add a character 'X' in front of the column name. Is this a normal default behaviour of R? Why has it got this behaviour? Can it be changed? What would be the side effect? Thank you. Regards, Gilbert [[alternative HTML version deleted]]

Hello, I want to have an operation foo with variable number of operands, and I am trying to achieve it using multiple operations. Let's say I want to have [FOO r1, r2], I am constructing the DAG as follows : consumeArg(r1) -> consumeArg(r2) -> FOO -> arg(r1) -> arg(r2) Note that the arrows are all "Chain"s. I need to have consumeArg(r1) because, I don't want the producer of r1 to be scheduled between FOO and arg(r1). Similarly I...
