...takes an i64 as parameter instead of a double* for my_struct. This parameter is then coerced into double* using an inttoptr instruction. The code in BasicAliasAnalysis.cpp which is triggered for x86 is the following: // Function arguments can't alias with things that are known to be // unambigously identified at the function level. if ((isa<Argument>(O1) && isIdentifiedFunctionLocal(O2)) || (isa<Argument>(O2) && isIdentifiedFunctionLocal(O1))) return NoAlias; isIdentifiedFunctionLocal(V) returns true for a noalias argument (such as result), but...

I think I want (actually I want octal because I was raised PDP-11, but not trying to rock that boat): ABCD\{LF}EFG\[89]\\ or similar for printf("ABCD\nEFG%c\\", 0x89). The point is to be - compact for mostly ascii - unambigous - guaranteed printable only - otherwise as simple as possible How would people feel about adjusting upsdebug_ascii to do this? I would consider a PR if it is ok, and skip the effort if not.

I'm currently working on hardware construction library for C++ (similar to Chisel (which is written in Scala)). And since C++ has no standardized reflection, I use DWARF as a source of...

...inder alignment is already fulfilled. Adjusting the image size to protect the backup GPT will therefore cause new padding of one cylinder size. One could check whether the last 33*512 bytes of the ISO filesystem are occupied by a backup GPT. There are id texts and CRC-32 sums. So it would be quite unambigous. Nevertheless, this will stay guesswork and potentially risky for the content of the ISO filesystem. So i gave up the idea to unconditionally adjust filesystem size to image file size. It might neverthelss be a valuable option. E.g. --adjust_fs_size. Have a nice day :) Thomas

...seconds. Leap Seconds are announced officially by the IERS http://www.iers.org/iers/products/eop/leap.html RFC2822 explicitly refers to "local time" and to UTC. Local (or civil) time is ALWAYS UTC (modulo some hours). UTC, expressed (as it should be) in hours minutes seconds format, is unambigous. So, if you want to be consistent with rfc2822, use local time or UTC. I don't think you need the rigor of TAI, and, if you use TAI, your internal clock time will be 20+ seconds off from the time on people's watches, which is likely to cause trouble.

...names for types. It will become a problem when you need to use debuginfo as a C++ runtime reflection (I've already seen this in a couple of projects). Or when you need to go back from LLVM IR to Clang AST (I've already encountered this problem). I wonder if abi::__cxa_demangle guarantees unambigous names? If so, then I can just replace current incorrect names that Clang generates, with names from demangler. In this case I don't even need to patch gdb, it will work as is. -Roman 2018-03-05 10:46 GMT-08:00 Daniel Berlin <dberlin at dberlin.org>: > > > On Mon, Mar 5, 2018,...

Hi All, I have an script in R which accepts user inputs for certain parameters, particularly dates, which the user inputs as character strings. eg: > date1 <- "2009-01-21" The script later parses the input via the as.Date function: > as.Date(date1) However, as.Date encounters an error when the string does not represent an actual date. eg: > date1 <-

Hi all, This may seem like a dumb question, but I work for an entity that is soon converting to XP across the board, and I will lose the ability to install software on my own. The entity has a policy of only using software that has been purchased and "properly licensed" (whatever that means). This means I will soon lose the ability to use R at work - something I can't do without
