Hi, I am trying to compare the loop vectorizers effectiveness for different targets relative to each other. That way, I am hoping to find loops that are not vectorized - but could be - on my target by finding other targets doing this successfully. With some luck, there might be something in the Target files that could be fixed with improved vectorization as a result... I would like to do

...file-instr-generate -fcoverage-mapping clang flags) In my questions I refer to the two methods as llgcov-way and llcovprof-way respectively. Q1- How come size of instrumented code in llgcov-way turns bigger than llcovprof-way? I would imagine the other way because mapping information would go to *.gcno files. Q2- The instrumented executable size of both llgcov-way and llcovprof-way (with and without optimization) is bloated 2x to 10x or in some cases 50x depending on the program. Here is output of size command for the variations on a simple test program that I wrote: text data bss...

Seems like something infinite-recursion like to me: $ clang --version clang version 6.0.0 (trunk 317833) Target: powerpc64le-unknown-linux-gnu $ clang -c test.ll warning: overriding the module target triple with powerpc64le-unknown-linux-gnu [-Woverride-module] ... #255 0x0000000012b07a78 llvm::DwarfUnit::getOrCreateTypeDIE(llvm::MDNode const*) ...

Hi Tim, Thanks for your suggestion! I built LLVM with Debug and tried this with my custom pass. But it has the following error error: unable to load plugin '../../trace-extractor/build/TracePass.so': '../../trace-extractor/build/TracePass.so: undefined symbol: _ZTIN4llvm10ModulePassE’ Originally I used a builtin Clang in the system and it does not produce this issue. When I search

Updated set of patches for coverage. Changes: - change copyright lines - use gcov: instead of cover: in commit comment - use #ifdef in xen/common/sysctl.c instead of dummy inline function - added base documentation in docs/misc - added -h option to xencov
