This novice coder roughly understands the difference between instance and local variables thanks to David Black''s excellent book, but I''m still unclear as to when and why a either is more desirable to use. In general, I use instance variables in my controller and local in my views, but I''m not sure as to why or if this is correct. Thanks Joe Kowalski

Given a pointer, does any addrspacecast affect the pointer's dereferenceablity ? For example, %pm = addrspaacecast float addrspacecast(n)* %pn to float addrspacecast(m)* %r = load float addrspace(m)* %pm In another word. the question is whether the following is true ? isDereferenceablePointer(pn) == isDereferenceablePointer(pm) [Note that the function is defined as

Hi Tim, Thank you for your response. I need that immediate value latter to concatenate to registers' names (which I am doing during assembly printing). Also just Updating some status for my questioin: I have continued with using *Defs* list. It allows me to keep Registers as an implicit operands of /*MachineInstr*/ and later during its lowering pass them to the /*MCInstr*/. Now seems I need

Hi all, I've recently decided to take a look at Theora for the first time. The 1.1.1 release compiles fine, but the compiler generates a fairly large number of warnings about "suggest parentheses around + or - inside shift". I've had a look at a few of these and sometimes it isn't obvious what is meant to happen. I guess the code is all correct though as I'm sure

I have a method in a controller that invokes a render :partial => ''some_partial_view'' In that view, I''m trying to access a method defined in a model, like this; <% for view in @an_array %> <% local_var = view.some_method() %> <% another_var = view.a_column_name %> etc.. I am getting an undefined method error but the model is accessible

Hi, I am trying to execute a simple hello world program compiled like so: path/to/compiled/clang -o test --target=aarch64-linux-gnu -march=armv8.5-a -fsanitize=hwaddress --sysroot=/usr/aarch64-linux-gnu/ -L/usr/lib/gcc/aarch64-linux-gnu/10.1.0/ -g test.c However, when I look at the disassembly, there is an unknown instruction listed at 0x2d51c: 000000000002d4c0 main: 2d4c0: ff c3 00 d1

I suspect that this is hitting the issue that I mentioned here: https://reviews.llvm.org/D65857#1621335 We may need to do what I suggested there and restrict global tag entropy on non-Android Linux to 7 bits. You can try working around this issue for now by using lld as the linker (-fuse-ld=lld). Peter On Mon, Jun 22, 2020 at 1:37 PM Mitch Phillips via llvm-dev < llvm-dev at

Hello, I am testing out a partial that calls another, general purpose partial as part of its processing. Is there a class I can mock in Rails views to accomplish what I need? That is, could I do something like the following: SomeClass.should_receive(:render).with(:partial => "foo", :locals => { :bars => bars }) I tried breakpointing the view, and it looks like I am greeted

Hi everyone, I experience some problems with adressing of data.frames when I retrieve some information for geographical position (ypos, xpos) ot of a MySQL Database and want to perform some simple statistics. The problem is adressing the dataframes with a construct like rawdata[c(type)] vs. rawdata$TEMPMIN to retrieve the numerical information and not a string (I want to store the numerical

Dear R-Users, my dataset contains timeseries that are structured into task-specific epochs as labelled by a factor and a boolean variable for labelling each data-point within the series as artefact or non-artefact. Now there's no problem in addressing continuous task-specific time-series that are free from artefacts as long as artefacts extend to either boundary of adjacent timeseries but

Hi all, I'm trying figure out how to implement support for Small Data Addressing (SDA) for an out-of-tree PowerPC target. The short description of SDA is that small globals are gathered in the same memory area and addressed using a base register + an offset. From what I've seen the Hexagon target already support this but as that target doesn't seem to support writing object files it

Thanks for the confirmation. From the assembly that was sent on the other branch of the thread: > .set .L.str, .L.str.hwasan-3458764513820540928 -3458764513820540928 = 0xd0 << 56 i.e. a "negative" tag. So this appears to be the issue exactly. Peter On Mon, Jun 22, 2020 at 1:55 PM Derrick McKee <derrick.mckee at gmail.com> wrote: > Using lld fixes this issue. >

Hi, Sebastian Kanthak of the file_column-Plugin wrote once: "is the photo object inside a local variable or an instance variable (e.g. photo or @photo)? url_for_file_column only works with instance variables, like all other active record form helpers. Could this be the problem?" So I''m using file_column in a partial, e.g. <%= render (:partial => "product",

Dear all, I'm using R 2.8.1 under Vista. I programmed a Simulation with the code enclosed at the end of the eMail. After the simulation I want to analyse the columns of the single simulation-runs, i.e. e.g. Simulation[[1]][,1] sth. like that but I cannot address these columns... Can anybody please help?

Dear all, I'm sitting here just in front of my new PC@work and wonder about the following question: * How can I adress multiple CPUs (cores) out of R to speed up the simulations I run? * What are the prerequisites to do so? Maybe anyone could give me a hint where to start reading? Regards, Thomas P.S.: I searched the R-archive to find an answer but did find none.

+ Erik, who implemented DR1579 Originally, I had the warning similar to GCC's warning, but took it out due to not having DR1579 implemented in clang (warning changed in r243594) Erik in r274291 implemented DR1579, although PR27785 didn't mention anything about std::move It looks like what's happening is that Clang and GCC handles the return differently. Clang needs the std::move

This round implements all of the review comments from V2 and all patches are now acked. Unless there are any objections I intend to apply later this morning. Ian.

Hi, When using Wine to run Windows ARM64 executables on Linux, there's one major ABI incompatibility between the two; Windows treats the x18 register as the reserved platform register, while it is free to be clobbered anywhere in code on Linux. The Wine code sets up this register before passing control over to the Windows executable code, but whenever the Windows code calls a function

Hi all, All of the data types are 32 bits and the pointer is 32 bit. Therefore, I need word adressing instead of byte adressing to use 8 GB memory. I was told that R600 uses word adressing and I looked at its codes but I could not find where the backends handles word adressing. Do you have any ideas about it? Thanks in advance. -------------- next part -------------- An HTML attachment was
