Hi R sages, Here is my latest problem. Consider the following toy example: x <- read.table(textConnection("y1 y2 y3 x1 x2 indv.1 bagels donuts bagels 4 6 indv.2 donuts donuts donuts 5 1 indv.3 donuts donuts donuts 1 10 indv.4 donuts donuts donuts 10 9 indv.5 bagels donuts bagels 0 2 indv.6 bagels donuts bagels 2 9 indv.7 bagels donuts bagels 8 5 indv.8 bagels donuts bagels 4 1 indv.9 donuts donuts donuts 3 3 indv.10 bagels donuts...

Hello all, I am trying to write a program in R in which I call a function multiple times within a loop. The problem is that sometimes the function breaks down while calling another function, and produces an error message that breaks my loop and the program stops. I would like to keep the loop running when this function breaks down, and just move on to the next iteration in the loop. Is there

I was looking over some of my specs. I was thinking that the following: @game.should_receive(:name).and_return(''The Battle for Blaze'') @game.should_receive(:people).and_return(5000000) @game.should_receive(:activated).and_return(true) Would it look cleaner if I could do this instead? @game.should_recieve_and_return( :name => ''The Battle for Blaze''

Hello again, How do I split a data frame into smaller, completely separate data frames (rather than separate data frames comprising a single "list")? Consider the following data, and my coding attempt: x <- read.table(textConnection("id type number indv.1 bagel 6 indv.2 bagel 1 indv.3 donuts 10 indv.4 donuts 9"), header = TRUE) closeAllConnections() x.split <- split(x, x$type) This is where I'm stuck. Now I have one "list" comprised of different data frames, but what I want is separate data frames. Ideally, I'd like to design...

Hello again R users, I have a devilishly hard problem, which should be very simple. I hope someone out there will have the answer to this on the tip of their tongue. Please consider the following toy example: x <- read.table(textConnection("y x1 x2 indv.1 bagels 4 6 indv.2 donuts 5 1 indv.3 donuts 1 10 indv.4 donuts 10 9 indv.5 bagels 0 2 indv.6 bagels 2 9 indv.7 bagels 8 5 indv.8 bagels 4 1 indv.9 donuts 3 3 indv.10 bagels 5 9 indv.11 bagels 9 10 indv.12 bagels 3 1 indv.13 donuts 7 10 indv.14 bagels 2 10 indv.15 bagels 9 6"), header = TRUE) I am fi...

...I am on a linux x86-64 system (Fedora 13). Is gdb supposed to understand the generated DWARF? When I generate an executable with "clang -g" followed by "llc -O0" and feed it to gdb, I get "no debugging symbols found". What is the status of lldb on linux? thanks, bagel

I think I have read that there are plans to generate object code (e.g. ELF) directly in addition to assembly language source. If so, are there plans to support branch relaxation for targets which support long/short branch displacements? This is typically done in assemblers. thanks, bagel

Thanks, I seem to have gotten sub-registers to work. I can't seem to suppress the zero-extend sometimes. There is no need to explicitly zero extend bytes to words on this machine as all byte operations do that. I have also gotten some memory-to-memory to work.

...t (which is hard to express in C) something like void foo () { int bar[20] = { 42, 42, ..., 42 }; } I don't want to do a memcopy of the 20 element constant array, and memset doesn't work here. I want an intrinsic that copys the scalar int constant 42 to each element of the int array. bagel On 11/10/2016 03:30 PM, Mehdi Amini wrote: > Hi, > > An alternative is to perform what is done for the equivalent C construct: > > void foo() { > char bar[20] = “hello”; > } > > -> > > @foo.bar = private unnamed_addr constant [20 x i8] c"hello\00\00\...

Assume an architecture that has multiple condition code registers, e.g., powerpc. Now assume that there are predicate instructions like thumb2, but can specify which condition code register they refer to. Now also assume that these predicate instructions themselves are predicatible, if executed they change the current predication state. Can LLVM handle multiple levels of predication? When is

...that doesn't have anything to do with multiprecision addition/subtraction. I am not aware of any way currently available to produce IR that will generate these nodes directly. But what is the use case? What IR pattern it would replace? — Mehdi > > On Fri, Feb 17, 2017 at 8:52 PM, Bagel via llvm-dev <llvm-dev at lists.llvm.org <mailto:llvm-dev at lists.llvm.org>> wrote: > On 02/16/2017 12:08 PM, Stephen Canon wrote: > >> On Feb 16, 2017, at 9:12 AM, Bagel <bagel99 at gmail.com <mailto:bagel99 at gmail.com> > >> <mailto:bagel99 at gmail....

...front-end can't use them because it is not written in C or C++. I need to know the exact layouts of the LLVM assembly metadata -- the textual form -- and what the fields mean. The comments in your examples are close. Perhaps you can add another section just on the textual format? thanks, bagel

...registers are declared as SubRegs? Also, this machine supports memory-to-memory operations in byte and word flavors. What do I need to look out for to support this. If have looked at the X86 *.td's, but that architecture is so complex it is hard to extract the information I need. Thanks, Bagel

...if a mov reg-to-reg proceeds or follows a 2-address instruction and turn it into a 3-address version? 3. Or do I generate 3-address and have a custom pass that checks if a source and destination register in a 3-address is the same and turn it into a 2-address? Anybody done this already? Thanks, Bagel

...ctions that return multiple values (as does my language), and DW_TAG_subroutine_type implementation currently supports, at most, a single returned value, this might be a bug. Looking at the code in lib/CodeGen/AsmPrinter/DwarfDebug.cpp around line 1035, this does appear to be the case. thanks, bagel
