Sorry, no progress on this front. If you have any ideas to correctly synchronize real/shadow stack in callgrind and can do some tests, this would be very welcome!

Josef: Hello, is there any news now. when do you can release the patches.

Hi Owen, callgrind currently is somewhat broken on ARM, as the tracking of entering/leaving functions is unreliable. Callgrind heavily uses the stack pointer for that. On x86, this works fine, as every call/return changes the SP, but on ARM, this is not the case. There are ideas and at some point, there were patches promised by someone, but unfortunately nothing useful up to now...

But I ran the same the same code through the callgrind on the arm64, it show me there is recursive cycle existed. Between two callgrind.out. file: In arm64: There is function name main’2. It meaning that there is recursive cycle. And it annote the source failed. In x86_64: There is no function name main’2 only main., It mean that there is no cycle. How can I resovle it? The compile options : gcc –g –O0 ./main.cpp The gcc version 4.9 Run options: valgrind --tool=callgrind ./a.out Callgrind_annote option callgrind_annote –auto=yes BR Owen ---------------------------------------------------------------------- -------- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
