Bug ID: 357014
Summary: Helgrind regression tests do not match expected
results if compiled with intel compiler
Product: valgrind
Version: 3.10 SVN
Platform: RedHat RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: helgrind
Assignee: jsew...@acm.org
Reporter: tatyana.a.mine...@intel.com
Created attachment 96242

Proposed patch
Several helgrind tests do not produce the expected results if Valgrind is
compiled with Intel compiler. The reason is that expected results contain call
stacks of helgrind functions. On Intel compilation, one of the functions in the
call stack is optimized out (due to tail call elimination), so the call stack
appears to be different.
The proposed patch adds alternate expected test results with a modified call
stack.
The differences between added .exp-icc files and corresponding .exp files are
listed in helgrind_deltas.diff file.
One of Valgrind suppression rules relies on this call stack, too. The proposed
patch adds a suppression rule that relies on the intel-specific call stack for
Intel-compiled version of Valgrind.
