Question 1: I am trying to get a function not to be inlined. What are llvm's rules pertaining to inlining? I have tried all of the standard gcc options for turning off inlining and they do not seem to work. Here is the sample code that I am working with: #include <stdio.h> void print_string(char* strval); int main() { char* strval = "Hello world\n"; while(1){ print_string(strval); sleep(15); } return 0; } void print_string(char* strval) { int i; for(i=0;i<12;i++){ putc(strval[i], stdout); } } gcc 3.2.2 does not inline this by default. Also, on llvm.c...

Hi, I tried to rewrite virt-rescue from C to OCaml. Goals were feature parity with C implementation, smaller codebase and hopefully better maintainability. I still don't know if I've covered everything right. So, please check it out. PS: my git send-email seems to be broken, so I'm sending it from thunderbird Thanks! maros

The warnings in daemon were aggravating and risky for development (too easy to miss new ones) so I spent some time last week and today working on removing them. The first patch gets us down to almost no warnings with the original -Wall setting. That was by far the hardest part. Once I'd done that, I enabled nearly all of gcc's warnings via gnulib's warnings and manywarnings modules

The 'may' function is a higher-order function (HOF) that replaces: match x with | None -> () | Some x -> f x with: may f x The idea comes from lablgtk (OCaml Gtk bindings) where it is widely used. If this change is clearer than previous code, then this could be used in many more places. However I previously steered clear from using HOFs like this because they can be

Hi Chris, this serie of patches updated the command "btrfs filesystem df". I update this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show". This patch was the result of some discussions on the btrfs mailing list. Many thanks to all the contributors. From the man page (see 2nd patch): [...] The
