Hi Shahzad, > Is it possible that we can use LLVM optimization beside O1, O2, O3 > along with dragonegg plugin? sure, try this: gcc -fplugin=path/dragonegg.so ...other_options_here... -S -o - -fplugin-arg-dragonegg-emit-ir -fplugin-arg-dragonegg-llvm-ir-optimize=0 | opt -pass1 -pass2 ... Here -fplugin-arg-dragonegg-emit-ir tells it to output LLVM IR rather than target assembler.

Thanks alot Chad for quick response. Does this means that, we can not use LLVM optimizations except O1, O2, O3, O4 and unroll-loops with clang? One more thing I would like to know that If I want to process multiple modules with opt at the same time like opt -adce *.bc then how is it possible with opt in one go, if I process all the bytecode files within Makefile. Thanks. Shahzad On Thu, Jun

Hello Duncan Is it possible that we can use LLVM optimization beside O1, O2, O3 along with dragonegg plugin?

Hello Duncan I tried your method and it works fine. What would be the next step to produce the final executable? I have tried the following but it is producing an error $ gcc -fplugin=/path/to/dragonegg.so -S *.c -fplugin-arg-dragonegg-emit-ir | opt -adce $ clang *.s Regards Shahzad On Fri, Jun 8, 2012 at 9:10 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi Shahzad, > >

Hello I need some help here please. If we compile source files directly in to native code: $ clang -O3 -lm *.c then the runtime is like following real 0m2.807s user 0m2.784s sys 0m0.012s and If we emit LLVM bytcode and apply optimizations $ clang -O3 -c -emit-llvm *.c $ llvm-link *.o -o comb.ll $ time lli ./comb.ll then the runtime is real 0m2.671s user 0m2.640s sys 0m0.020s But, if I

Hi Yes, they both are exactly the same.

Thanks Duncan It was really helpful.

Hello Duncan Sorry for the mistake. Actually that error occurred when I was compiling all the files at once, NOT in for loop. The for loop is working perfectly as it is dealing with individual files. I have now one new issue. Let me specify it briefly. If I compile the program using the following command line i.e. $ clang -O3 -lm *.c then $ time ./a.out real 0m2.606s user 0m2.584s sys

Hi, > Yes, they both are exactly the same. then I don't know what is going on. I suggest you send a copy of comb.ll to the list so that we can see for ourselves.

Hello everyone I have some data of the following type. 100 200 300 400 500 1.1 1.2 1.3 1.4 1.5 600 700 800 900 1000 1.5 1.7 1.9 2.0 2.4 With plot() and points functions I can plot these 4 lines of data. But I dont know how to do it with qplot or ggplot functions. The scenario is something like this: the hundreds should appear on x-axis and the fractional values of y axis. Thanks alot. MEMON

Sure. The comb.ll and data files are attached and can be invoked as the following $ lli comb.ll data -c Regards Shahzad On Tue, Jun 12, 2012 at 12:28 PM, Duncan Sands <baldrick at free.fr> wrote: > Hi, > > >> Yes, they both are exactly the same. > > > then I don't know what is going on.  I suggest you send a copy of comb.ll to > the > list so that we can

Hello. I spoke with some of the support staff at Digium regarding the Digium/Cepstral partnership. I was trying to find out when something may be available, and if there is documentation about the project. I was told that the project has already been released in to the CVS head, and is available to us now, but not available yet for the business edition. They had no documentation links

Hello everyone I am trying to use some LLVM optimizations like -die or -adce. Is it possible to use them along clang? Or is there a way where these optimization can be passed on to "opt" tool through clang, if opt is being used by clang behind the scenes? Thanks alot Regards Shahzad
