similar to: [LLVMdev] Runtime Array-Length

The toy language I've been playing around with represents all strings as a struct in llvm; struct string{ char *ptr; int str_len; int buffer_len; } And my AST has an interface like; String_AST{ int measure(); void copy(char *dest); struct string get_value(); } A constant string can be measured at compile time, for a string variable measure() just extracts str_len. Strings

However, how would one allocate the buffer for a string if you did not know the length of the string at compile time? For instance, using the api how would one reproduce the code for the following c++ function? std::string add(std::string a, std::string b){ return a+b; } When allocating the buffer required for the new string, one can determine the length at runtime, however I do not know how

All, Is it possible to create something which has the same effect of a variable-length phi node in the C++ api. Specifically, create a phi-node where the number of incoming values is not known at the time of its creation. If there is no such way of creating a phinode like that, would it be possible to create a dummy instruction and perform a replaceAllUsesWith? If so, what should the dummy

You can call addIncoming(). /// addIncoming - Add an incoming value to the end of the PHI list /// void addIncoming(Value *V, BasicBlock *BB) { assert(V && "PHI node got a null value!"); assert(BB && "PHI node got a null basic block!"); assert(getType() == V->getType() && "All operands to PHI node must be the same

Hi people, As usual I've tried a number of different approaches to this problem and can't figure it out. I don't have enough knowledge. Every time I do net rpc vampire I get this crap spewed at me: Use of uninitialized value in substitution (s///) at /usr/share/perl5/smbldap_tools.pm line 106, <CONFIGFILE> line 233.

I?m working on an OS project from github. There are two parts: Dovecot plugin - https://github.com/st3fan/dovecot-xaps-plugin Daemon written in Go - https://github.com/st3fan/dovecot-xaps-daemon # dovecot --version 2.2.10 Both parts worked fine on CentOS 6 but I recently rebuilt them both for CentOS 7 and have run into some errors. The plugin sends a notification over a socket to

In my model I''d like to write a method that accesses the attributes by name. A very simple implementation would be class MyModel < ActiveRecord::Base def get_value(attribute) return value_of_attribute end end Then I can call it with m.get_value(:name) to get the value of the name column in the db. I''m not sure what to put in for

Are you saying the textual form of IR can change, but bitcode doesn't? I don't know what you mean by assembly syntax. Is there a changlog entry when the textual IR changes?

The front end I'm building for an existing interpreted language is unfortunately producing output similar to this far too often; define void @foo(i8* nocapture %dest, i8* nocapture %src, i32 %len) nounwind { %1 = tail call noalias i8* @malloc(i32 %len) nounwind tail call void @llvm.memcpy.p0i8.p0i8.i32(i8* %1, i8* %src, i32 %len, i32 1, i1 false) tail call void

I partially worked out that to do an assign I will need to manually assign a temporary first and then load data into it, which also means I'll need to set up a temporaries list in my code assembler as allocations must be done before anything else? or is it fine to allocate a variable mid-way through a function and the compiler will manage it? With that as well, if I had a function that loads

Before this patch, Python would segfault once you pass a non-string key or value to node_set_value. It was also not possible to set bytes on Python 3 as Unicode was assumed (Python 2 was not affected by this). This patch fixes recognition of bytes for Python 3, but in addition it recognizes ints (includes 'long' in Python 2) for DWORD (LE + BE) and QWORDs. For this purpose, a new field

hi, i have a small form of textfields and i need to add these informations to a table in sqlite3 database. but i dont know how to do it. i mean that its small address book program. and ''id'' from ''clients'' table has to increments. i open database with : db = Database.open("data.db"), but then i dont know what to do... anyone can help? -- Posted via
