Hi, I have come across a csmith generated test case that made the MachineVerifier spit out: *** Bad machine code: Multiple connected components in live interval *** Having looked at what this might mean, it seems that ConnectedVNInfoEqClasses::Classify() was called on the LI in question by the verifier, and that it returned two equivalence classes, instead of just one, which is demanded by

Hi, guys I am interesting about how to get the switch case value form the Machine Instruction. I know the switch will be converted to jump-table in the Machine Instruction. And in the phase CodeGen , the case-value of SwitchInst can get esasly. but it seems no case -value in Machine Instruction. The MI as follows: Frame Objects: fi#0: size=1, align=0, at location [SP] fi#1: size=4,

Hi Jonas, Could you file a PR with your test case please?

Hi Jonas, When is the MachineVerifier complaining? I mean after which pass?

Some glitch in the emailer? I have received this message 3 times in a row!? I think that by the time it gets as far as MI-level there is no reversible method of determining the 'case' label at all. The reason I say this, is that I have often seen optimisations that coalesce groups of values into interesting logical tests and jump-tables are completely avoided. For example, a simple

Evan, et al., I've come across a small issue when using the if conversion pass in PPC to generate conditional returns. Here's a small example: ** Before if conversion ** BB#0: derived from LLVM BB %entry %R3<def> = LI 0 %CR0<def> = CMPLWI %R3, 0 BCC 68, %CR0, <BB#3> Successors according to CFG: BB#3(16) BB#1(16) BB#1: derived from LLVM BB

Hi, I'm having some trouble wirting an instruction in the X86 backend. I made a new intrinsic and I wrote a custom inserter for my intrinsic in the X86 backend. Everything works fine, except for one instruction that I can't find how to write. I want to add this instruction in one of my machine basic block: mov [rdi], 0 How can I achieve that with the LLVM api? I tried several

Thanks for your help. Is there possible I can get the realily case value form the MI? For the case in https://bugs.llvm.org/show_bug.cgi?id=34902. as follows. ############################# * GCC v7.1 generated assembly ############################# ** Options: -Os -marm -march=armv7-a foo: @ args = 0, pretend = 0, frame = 0 @ frame_needed = 0, uses_anonymous_args = 0 sub

Hi, I have a two columns data, the first column are values, and second column are the groups. For this example, there are 3 groups 1,2,3. How can I manipulate the values in the first column according to groups, say I would like to find mean, sum, and standard deviation for the different groups ? How do I plot data according to groups ? > t <- matrix(c(rnorm(10), 1,1,2,2,1,3,3,3,3,2),

Hello together, i have a list of numbers, like this one A B C 1.1 1.2 1.3 i export this list into an excel file and want now color these numbers according to her value. I want every color under 1,25 is red, and every color over 1,25 is green. How can i do this with "RDCOMClient" ? I know how to colour a complete row, like this task: U3R <- sh$Range(zellen_blue) U3RF <-

Is the code you have pasted with the PHIs feed to the register coalescer? I am trying to understand the setting to help debugging the problem. Also, what does -debug-only=regalloc tell you?

Ok, after a long detour I am back to where I have started. I think there is a problem at dep DAG construction. Let me try to convince you. Here is the C code we are dealing with: push () { struct xx_stack *stack, *top; for (stack = xx_stack; stack; stack = stack->next) top = stack; yy_instr = top->first; } If the loop never iterates, "top" will have

Dear all, I have a question on applying a function to the data according to factor levels. For example, for the data below, what is the best way to apply a function to "values" according to different levels of "samples" (1,2,3,4,5)? values ind sample 1 0.03325 1 1 2 0.03305 1 1 3 0.03185 1 1 4 0.03515 1 1 5 0.03375 1 1 6 0.01180

Hi, I'm a new user or R and I try to concatenate a several rows according with the value in a column. this is my data.frame and I want to concatenate my data.frame according with the column "b" and make a new data.frame with the information in the others columns. >table1 a b c d 1 E001234 TSA IP234 like_domain 2

HI,   I have searched the R-help achive, trying to find a way to sort columns in a data frame according to a specific list, but not be able to find a general way to do it.   My data frame contains columns, with each one named from a sample ID, and each sample was measured in a specific time, generating one column of data, now I would like to sort the columns according to the time course, so I have

I was wondering if one can have the coefficients of VAR model sorted according to variable names rather than lags. If you notice below, the output is sorted according to lags. >VAR(cbind(fossil,labour),p=2,type="const") VAR Estimation Results: ======================= Estimated coefficients for equation fossil: =========================================== Call: fossil = fossil.l1

Dear R experts, My problem is as follows: Suppose I have a data frame d comprising two variable a<-c(1:10) & b<-c(11:20). I now want to select a subgroup according the values of b. I know if I just want to select, say, b=17, I can use f<-d[d$b==17] and R will give me > f a b 7 7 17 However, if now I want to select a subgroup according to b==e<-c(13,15,17), then the

Hi there, I have a large amino acid csv file like this: input.txt: P,LV,Q,Z P,VL,Q,Z P,ML,QL,Z There is a problem with this file, since LV and VL are in fact the same thing. How do I order each element according to alphabetical order so that the desired output would look like: output.txt: P,LV,Q,Z P,LV,Q,Z P,LM,LQ,Z -- View this message in context:
