Hello, as a newbee, I'd appreciate some support on regression test setup. Specifically, I am interrested in the feature of tail call optimizations for the ARM v6m targets. This feature currently seems to be completely deactivated at the moment (v6m being based on thumb1 ?!). According to my code-reading, this feature will involve some modifications in epilogue generation. My work on a gcc

...file data".  Or, if you're using a build of LLVM more than a few months old, coverage data can be silently dropped. 4. Then, you add "-fprofile-instr-generate -fcoverage-mapping -mllvm -enable-value-profiling=false" to your CFLAGS. 5. Then, you build and run the image in the semihosted environment. If everything works, you get a file with raw profile data, and use the normal workflow to convert it into a report. Areas that required LLVM changes: 1. The copy of libclangrt_profile.a for the target.  Given that we already were using builtins from compiler-rt, the primary change...

Hi cschen, It seems that libunwind (the one included in libcxxabi) is mandatory at the moment. Use the second build command instead: $ CROSS_COMPILING=arm ENABLE_LIBUNWIND=1 ./scripts/compile-all.sh Logan On Tue, Oct 7, 2014 at 5:32 PM, gamma_chen <gamma_chen at yahoo.com.tw> wrote: > After do "sudo apt-get update", the following are pass. > > Install the
