search for: arange

Hello I've been looking at a debuginfo issue on an out-of-tree target which uses DWARF aranges. The problem is that aranges are generated for both data and code objects, and the debugger gets confused when program addresses overlap data addresses. The target is a Harvard Architecture CPU, so the appearance of overlapping address ranges is not in itself a bug as they reside in different add...

Yes. This. The system mostly provides us the ability to disambiguate addr...

...it has never come up before that I’m aware of. So, when we emit DWARF, we assume a flat address space (unconditionally setting the segment selector size to zero), and llvm-dwarfdump will choke (hopefully cleanly, but still) on an object file that uses DWARF segment selectors. The point of .debug_aranges is to accelerate the search for the appropriate CU. Yes you can spend time trolling through .debug_info and .debug_abbrev, decoding the CU DIEs looking for low_pc/high_pc pairs (or perhaps pointers to .debug_ranges) and effectively rebuild a .debug_aranges section yourself, if the compiler/linker...

Hi, I'm new to R and I'm finding it quite a chore trawling through the R documentation to find a function to carry out simple atomic tasks. Is any one aware of R help documentation that is aranged in functional categories for e.g.: String manipulation File I/O Dataframe, List manipulation etc, etc ...

Hello I have a Junghanns ISDN BRI card for incoming calls and use SIP Polycom IP300 phones. My config files look like this: features.conf pickupextn = *8 zapata.conf context=frompstnisdn group=1 callgroup=1 pickupgroup=1 I also edited sip.conf like this: group=1 callgroup=1 pickupgroup=1 But on internal and incoming calls if I dial *8 from any phone I cannot pickup. Do I need to add

...es while I was working up the idea, and came down on the side of not doing it. Not opposed to having it, but we haven't really thought about what it would look like. (Emit every kind of standard thing we know about, and no non-standard things at all? So we'd get pubnames and pubtypes and aranges but no Apple attributes or accelerator tables and not the GNU TLS opcode. Is that a useful mode to have?) Re where to put the guidelines: ought to be committed to the repo somewhere, although whether it's as a lump of text in a docs webpage or a lump of commentary in some source file is not...

Dear R-users, Does anybody know a good way to create and use several graphical devices at the same time in interactive mode? Ideally, I'd like to open 2 to 3 devices and assign names to them. This way, I could make any addition/modification/update to a particular device using its name. I did not see anything like a name argument in ?X11. Is there an alternative? Thanks in advance for your

...tuning" option, in favor of the historical GDB default, because in fact it wasn't really clear what "no tuning" should mean. The best answer I can come up with is: Emit all standard things that we know how to emit, and no non-standard things. This would mean: pubnames/pubtypes, aranges, no accelerator tables, standard TLS opcode. Possibly type units, although that's currently not a tuning thing, and support for it isn't particularly widespread. If LLVM doesn't do target-specific defaulting, then Clang would have to. Second: The GNU TLS opcode thing is really a GDB...
