Hi,
My patch for warning about strict aliasing violation is not strict
enough. Current implementation of strict_aliasing_warn has not
consider tbaa. So a test case gcc/testsuite/g++.dg/opt/pmf1.C will
emit additional warning whereas it shouldn't do.
My patch is not good for comm

Hi Richard,
Do you think this version is good enough to commit to trunk? I have
asked Andrew to commit for me. If it is not good enough, I may ask
him not to do this.

Hi,
This patch is to improve the output of strict_aliasing_warning. This
version will output the expression of rhs, type of that expression,
and the type of lhs. That make it easier to debug strict aliasing
bug.
* tree-inline.c (setup_one_parameter): Add strict aliasing check.
