similar to: Global variables - collision?

For LLDB I'm writing a dumb module pass that removes all global variables, by running the following code: bool erased = true; while (erased) { erased = false; for (Module::global_iterator gi = llvm_module.global_begin(), ge = llvm_module.global_end(); gi != ge; ++gi) { GlobalVariable *global_var =

Hi Ben, That did help. I continue to notice the virtual register in the program. I use LLVM 3.4. The program i am looking at is a very simple one. Listed below int global_var; int *global_ptr; int32_t main(int32_t argc, char ** argv){ int p = 10; int k = 20; int *pp; char *c_pp; pp = &k; global_ptr = pp; pp = &p; global_ptr = &global_var; return 0; } BR/Nizam

Umm ok, but i've the strange feeling that i'm missing something.. First a simple question: getelementptr with

In r219010, I merged integer and string fields into a single header field. By reducing the number of metadata operands used in debug info, this saved 2.2GB on an `llvm-lto` bootstrap. I've done some profiling of DW_TAGs to see what parts of PR17891 and PR17892 to tackle next, and I've concluded that they will be insufficient. Instead, I'd like to implement a more aggressive plan,

Hi, I'm writing a Scheme compiler in C++ with the LLVM library. The dynamic type system is hard to tackle with direct LLVM from the C++ lib, so I'd like to throw the work off into a C support library I could link the compiled Scheme with. How can I generate code that depends on/calls external symbols? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, is there a opt pass that replaces the SSA virtual registers to stack-variables? I want to eliminate the SSA virtual register from my IR.

Hi Devang, I convert all global variables in a file to thread local at the IR level. i.e. compile example_llvm.c to IR example_llvm.ll and change global variables to thread-local variables. I also insert a function call just before access of the global(now thread-local) variable. I also insert a local variable in main. Does these operations in any way effect the debug metadata ? I do not face

In your example, you do not need to update debug info for @global_var at the moment. We are not identifying tls in debug info yet.

You'll notice that your function doesn't take an object of type base, but a pointer to it. This is important - in a language such as LLVM where actual structures can be

For those interested, I've attached some pie charts based on Duncan's data in one of the other posts; successive slides break down the usage increasingly finely. To my understanding, they represent the number of Value's (and subclasses) allocated. On Mon, Oct 13, 2014 at 3:02 PM, Duncan P. N.

Hi! i'm tring to figure out how classes and dependencies can be mapped to llvm. I've read on docs that nesting can be used: class base { int Y; }; class derived : base { short Z; }; becomes: %base = type { int } %derived = type { %base, short } That's ok, but now the question is: how do i encode a function that takes "base" type so that it also takes "derived"

Still gathering data on this one, but it's easy to reproduce the case insensitive collision. AIX 5.2 Samba 3.0.7. in unix create two dirs on a user's [homes] share: CISS-102 ciss-102 put files from windows (I used XP sp1) into just one of them, then go and view the other. they have the same contents. on fresh smbd, if you start with the empty dir then both appear empty.
