Interesting, so I guess we can check for whether it's an array type and adjust accordingly instead? Blocking *all* global variables without definitive initializers feels a bit much to me, especially if they have primitive types (i.e. integers) that don't have the potential to be screwed around with like this.

When you first visit my site, you see a snippet (the first 75 words) of the most recent post. If it exceeds 75 words, a link will be appended to extend the post and read it in full. Now, my problem is when I post a code snippet, and I use "pre" tags to preserve its formatting, I don''t want that to show up on the snippet... only on the full version of the post. The reason is

I am not convinced this is a jump-threading issue, but in the domain of ScalarEvolution. ScEv would need to find out which of the exits are taken or whether it loops infinitely. One can see that it exits after 10000 iterations, but ScalarEvolution cannot tell: https://godbolt.org/z/dCqdvv Michael Am Mo., 3.

How does the code you would like to have look like? I don't see a relevant difference compared to gcc: https://godbolt.org/z/F-oah4 (clang unnecessarily introduces another temporary register, but that seems unrelated) Michael Am So., 2.

Holy crap, I completely missed that. I'm sorry! That's my fault.

Hello, What is the best method to replace a substring within a string? I''m trying this: url.gsub(string_to_replace,replacement) but i get the following error: undefined method `rewrite'' for #<String:0x3711a58> -- Posted via http://www.ruby-forum.com/.

Since the bug report here: https://bugs.llvm.org/show_bug.cgi?id=44679 I've been thinking about cases like it, such as: https://godbolt.org/z/Fwq8mn I wonder what we can do about this in a general sense. As far as I can tell, the jump threading algorithm is *really* conservative, which is one reason this isn't working as well as I'd hope; however, we don't want to produce

It's not about the pointer per se but the object it points to. If we have 2 objects of which we know the minimal/maximal size respectively we can sometimes conclude the objects must be different. Accesses to different objects do not alias. We already use that logic but we don't have the upper bound size as an attribute. Hence, it only applies if we know the exact size, basically is we see

Hm. I assumed that JumpThreading would be the primary factor in optimizing code like this. Guess not. I'll need to look into SimplifyCFG to see what prevents it from doing the same thing to the other loop: https://godbolt.org/z/F6NjdG On Mon, Feb 3, 2020 at 3:09 PM Michael Kruse <llvmdev at meinersbur.de> wrote: > I assumed the LLVM-IR behind the godbolt link represented the C code

Hello, I'm wondering how exactly LLVM deals with passes that open up opportunities for other passes. For example, InstCombine says that it opens many opportunities for dead code/store elimination. However, the reverse may also be true. How does LLVM currently handle this? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hey everyone, I was looking into how the global optimization pass fares against things like what's reported in https://bugs.llvm.org/show_bug.cgi?id=44676 Looking at this, I think it would be pretty trivial to optimize that down given that there are already threading assumptions made: https://godbolt.org/z/u6ZqoB Is this something I can look into? Another thing is that currently *all* external

I'm trying to get a XP Pro computer to join my Samba 2.2.2 controlled domain. I get an error something can't find the network? With this exact configuration I can add Win2K computers no problem. I have the add user script in my smb.conf file and I have also tried manually adding the computer to /etc/passwd using useradd. Is there something I'm missing for XP? Thanks.

I was thinking today, it would be nice if a view could tell a model how to format it''s data for that particular view. Kind of like, the view is bestowing instant, and temporary knowledge on the model for the duration of the views run. It seemed to me that this would be more objecty than say a helper that formats a string format_my_string( my_string ) Instead, in my view. Lets assume I

Hi, I want to automate somewhat the addition of created_by/updated_by fields on my models (i.e. to include username). What''s the best/recommended way to do this? Would it be to: a) Find out how to extend the ActiveRecord::Base itself (I haven''t extended a class before yet) b) Use a plugin type approach where you have to add a tag manually to each model file which then
