For two weeks bootstrapping gcc does not work anymore for me since -Werror
is used. The problem appears in stage 2, the previous stage works. This
is on Fedora 44 with gcc 16.1.1:
/home/drepper/gnu/gcc/gcc/tree-vect-stmts.cc: In function ‘bool
vectorizable_load(vec_info*, stmt_vec_info, gimple_stmt_iterator*,
slp_tree, stmt_vector_for_cost*)’:
/home/drepper/gnu/gcc/gcc/tree-vect-stmts.cc:10408:47: error: ‘stride_step’
may be used uninitialized [-Werror=maybe-uninitialized]
10408 | = gimple_build_assign (newoff,
POINTER_PLUS_EXPR,
|
~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~
10409 | running_off,
stride_step);
|
~~~~~~~~~~~~~~~~~~~~~~~~~
/home/drepper/gnu/gcc/gcc/tree-vect-stmts.cc:10156:25: note: ‘stride_step’
was declared here
10156 | tree stride_base, stride_step, alias_off;
| ^~~~~~~~~~~
This seems legit. Since this is the trunk version I have filed a bug.
Should I?
