vtune opening wrong source code file

Sylvain — Wed, 02 Jun 2021 11:14:48 GMT

I use vtune 2021 to analyze a c++ program I wrote compiled with gcc under linux. Problem is when editing the main function, the source code file opened is an header file and not the ccp file.
I added the source file path but does not help.
I checked that I compiled with -g.
I tried adding all those flags, but did not help :
-shared-libgcc
-gdwarf-3
-fno-eliminate-unused-debug-symbols
-femit-class-debug-always
-fno-merge-debug-strings
-fvar-tracking
-pipe
-fvar-tracking-assignments
-gcolumn-info
-gstatement-frontiers
-gvariable-location-views
-fno-eliminate-unused-debug-types
-fno-omit-frame-pointer

Any idea what I did wrong ? Or is it a bug ?

For example on command line I get

vtune -report hotspots -column=source,instructions,cpi -r /home/sylvain/intel/vtune/projects/Test\ SIMD/r007hs -source-search-dir=/home/sylvain/Recherche/Development/optim_robot_linux/test_vector_matrix_simd/ -search-dir=/home/sylvain/Recherche/Development/optim_robot_linux/test_vector_matrix_simd/bin/Release/ -search-dir=/home/sylvain/Recherche/Development/optim_robot_linux/test_vector_matrix_simd/obj/Release/

It could be caused by 2 possible reasons:
1. quality of the debugging information generated by compiler (What compiler version is used?);
or
2. improper handling of the debug info in VTune in some cases;
To understand what is wrong exactly we need a reproducer: this binary file + VTune result directory.

You can also try to verify correctness of the debug information in your executable file with Linux tools like addr2line.

Thank you for your quick answer

Find attached like proposed the binary and the vtune result directory. I looked at addr2line, but do not know which address I should check.

Best regards,

Sylvain

Thank you.
I've downloaded the attachments and reproduced this issue. I'll open an internal bug request on VTune.

Hello,

Sorry for the late answer, I was busy on other work.

The new version indeed solves the problem.
