Hi, I am looking for a solution to boot MY system on any PC. To store most of the system and all of my data I want to use an USB storage (in my case an external USB harddisk (2.0 capable)). Since booting off an USB device is not an universal thing I would prefer to have a boot disk with a minimal system - just enough to load most (all?) of the system from the attached USB device. Is this an

...TE definition after the #else needs to have the same number of arguments (I think so anyway, the -traditional CPP semantics are pretty fscking strange!). With this patch I am able to define elfnotes in assembly like this with both old and new assemblers. ELFNOTE(Xen, XEN_ELFNOTE_GUEST_OS, .asciz, "linux") ELFNOTE(Xen, XEN_ELFNOTE_GUEST_VERSION, .asciz, "2.6") ELFNOTE(Xen, XEN_ELFNOTE_XEN_VERSION, .asciz, "xen-3.0") ELFNOTE(Xen, XEN_ELFNOTE_VIRT_BASE, .long, __PAGE_OFFSET) Which seems reasonable enough.

All of this information is contained in the DWARF debug info that you must generate. Are you generating DWARF? If not, you will need to. If so, please attach an example program that contains DWARF and specify which function you are having trouble getting variable information for.

Hi, all I ported llvm backend and lldb recently. Both tools can basically work. lldb is able to debug programs in asm style and frame unwinding is OK. But "frame variable XX" does not work because lldb is not able to determine the address of XX from debug info. Can someone give any clue? Thanks in advance. -- 杨勇勇 (Yang Yong-Yong) -------------- next part -------------- An HTML

Hello everyone, I've added the "S" suffixed versions of ARM and Thumb2 instructions to tablegen. Those are, for example, "movs" or "muls". Of course, some instructions have already had their twins, such as add/adds, and I leaved them untouched. Besides, I propose the codegen optimization based on them, which removes the redundant comparison in patterns like orr
