* common.opt (fstrict-overflow): Alias negative to fwrapv.
* doc/invoke.texi (fstrict-overflow): Remove all traces of
-fstrict-overflow documentation.
* tree.h (TYPE_OVERFLOW_UNDEFINED): Do not test flag_strict_overflow.
(POINTER_TYPE_OVERFLOW_UNDEFINED): Test !flag_wrapv instead of
flag_strict_overflow.
* ipa-inline.c (can_inline_edge_p): Do not test flag_strict_overflow.
* lto-opts.c (lto_write_options): Do not stream it.
* lto-wrapper.c (merge_and_complain): Do not handle it.
* opts.c (default_options_table): Do not set -fstrict-overflow.
(finish_options): Likewise do not clear it when sanitizing.
* simplify-rtx.c (simplify_const_relational_operation): Do not
test flag_strict_overflow.
ada/
* gcc-interface/misc.c (gnat_post_options): Do not set
-fstrict-overflow.
* c-c++-common/Wlogical-op-1.c: Add -fwrapv to restore previous
behavior.
* gcc.target/i386/pr46253.c: Make i unsigned to avoid warning.
