For the sample profiler, I need to determine the location of the first user instruction in the function. This can be the LOC where the function header is or the LOC of the actual first instruction, it doesn't really matter. But it needs to be consistent wrt -g and -gline-tables-only. Currently, I'm scanning for the first non-zero line number from the top of the function. This skips over the frame setup instructions emitted by the compiler, that have no LOC, but it gives me different results depending on whether -g or -gline-tables-only is used, and whether the...

Both -g and -gline-tables-only should contain the information needed to get the stack trace with inlining (at -O2 and higher). We actually rely on that in sanitizer tools. As David mentioned, we build the code with -O2 and -gline-tables-only and use llvm-symbolizer to get stack traces...

...f to remote mount a file system. I'm trying an etherboot floppy. When I boot the system finds the dhcp server and gets the right file name but then it gives me the message "not a valid image." A quick search of the net didn't help much. Any clues to hand out?

...abline(a=0,b=200) abline(a=0,b=300) abline(a=0,b=80) 2. when plotting with type "l" and with values far beyond the limits of the plot, semi-random lines appear on the plot. plot(exp(1:100),ylim=c(0,10),type="l") Any thoughts? I poked a little bit at this myself: abline calls GLine, neither of them seems to do much checking whether the endpoints of the line to be drawn are way outside of the window (I guess that XDrawLine, which gets called by GLine, can't handle this). I guess this should probably be fixed at the the level of GLine (it might fix both of the above problem...

...file for me. However, when I inspect this with the sancov tool, all of the line numbers it reports are "<invalid>:0". I can list the covered and uncovered functions successfully, but without locations it's really hard to do anything with that information. I've built with -gline-tables-only, as is the default when building llvm with sanitizers enabled. Have you seen this before? Am I doing something obviously wrong?

I've been trying to figure out a parameter that will let you separately adjust the parameters for the axis line from the tick mark. In the following example, I would like to suppress the axis line, but keep the tick marks. Thanks, Andrew foo <- data.frame(x=1:3, y=4:6) plot(foo$x, foo$y, type="n", axes=F) points(foo$x, foo$y) axis(side=1, at=foo$x, lty=0) #would like to figure

...ble to match during the profile-use phase. The problem seems to be that we are missing DW_TAG_subprogram for all the functions in the file. Attached are the dwarf dumps of the same program. One compiled with my system's clang 3.4 and the other with today's trunk. In both compiles, I used -gline-tables-only. The trunk version is missing all the subprogram tags for the functions in the file. This breaks the sample profiler. Should I file a bug, or is -gmlt going to be like this from now on? The latter would be a problem for us. Thanks. Diego. -------------- next part -------------- An H...
