[Bug middle-end/55030] [4.8 Regression]: gcc.c-torture/execute/builtins/memcpy-chk.c execution, -Os (et al)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55030 --- Comment #18 from Eric Botcazou ebotcazou at gcc dot gnu.org --- FWIW, I've bootstrapped and regtested gcc 4.9 with r192676 reapplied and the dse.c and cselib.c hunks of r193802 reverted on several hosts (x86_64, sparc64, powerpc64, armv5tel, m68k) without regressions. Let's just reapply r192676 on the mainline. We just need to make sure that the failures on i686 don't reappear.

[Bug c++/57555] Warning on negation of constexpr uint8_t being assigned to uint8_t
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57555 --- Comment #4 from Marc Glisse glisse at gcc dot gnu.org --- The warning is correct, but it is arguably unhelpful in this case, which is made worse by the fact that -Woverflow is enabled by default. We do not warn for uint8_t ret = 0; ret += ~foo; with -Wall -Wextra, which is quite similar. Changing this behavior would be hard, since when we emit the warning we have forgotten where the constant was coming from. bar doesn't warn because the constant would fit the signed type corresponding to uint8_t (int8_t), a heuristic to reduce the noise produced by this warning.

ChangeLog says this is probably my fault... c_build_vec_perm_expr is missing some code like we can find in build_x_unary_op for instance: if (processing_template_decl) { if (type_dependent_expression_p (xarg)) return build_min_nt_loc (loc, code, xarg, NULL_TREE); xarg = build_non_dependent_expr (xarg); } RID_BUILTIN_SHUFFLE is handled very early in parser.c which directly calls c_build_vec_perm_expr. I guess we could use build_min_nt(VEC_PERM_EXPR,...) to store the template version, and make sure that c_build_vec_perm_expr is called once the types are instantiated (in tsubst_copy(_and_build)?).
