search for: _instr

...t adds some code (say, function calls) before some memory access instructions and marks those calls with some special metadata. I want the compiler to lower the instrumentation code to a sequence of no-ops while generating the object code. For example, the assembly for the following code: 1 void _instr(); // the instrumentation function 2 3 void foo(int *x) { 4 _instr(); 5 *x = *x + 1; 6 _instr(); 7 } should look like: 0000000000000000 <foo>: 0: 55 push %rbp 1: 48 89 e5 mov %rsp,%rbp 4: 48 83 ec 10 sub $0x10,%r...

...t of xen Linux/ia64 domU paravirtualization, not self complete. You can get the full patched tree by typing git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/ A paravirtualized guest wants to replace ia64 intrinsics, i.e. the operations defined in include/asm-ia64/gcc_instrin.h or include/asm-ia64/intel_instrin.h, with its own version. (At least xenLinux/ia64 does.) So we need a sort of interface to do so. I want to discuss on which direction to go for, please comment. This paravirtualization corresponds to the part of x86 pv_ops, Performance critical code written...

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it
