Subject: [PATCH 5/5] Formatted printing for dump_* in the middle-end
Date: Fri, 27 Jul 2018 21:47:00 -0000 [thread overview]
Message-ID: <1532730752-10525-6-git-send-email-dmalcolm@redhat.com> (raw)
In-Reply-To: <1532730752-10525-1-git-send-email-dmalcolm@redhat.com>
This patch converts dump_print and dump_printf_loc from using
printf (and thus ATTRIBUTE_PRINTF) to using a new pretty-printer
based on pp_format, which supports formatting middle-end types.
In particular, the following codes are implemented (in addition
to the standard pretty_printer ones):
%E: gimple *:
Equivalent to: dump_gimple_expr (MSG_*, TDF_SLIM, stmt, 0)
%G: gimple *:
Equivalent to: dump_gimple_stmt (MSG_*, TDF_SLIM, stmt, 0)
%T: tree:
Equivalent to: dump_generic_expr (MSG_*, arg, TDF_SLIM).
Hence it becomes possible to convert e.g.:
if (dump_enabled_p ())
{
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not vectorized: different sized vector "
"types in statement, ");
dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, vectype);
dump_printf (MSG_MISSED_OPTIMIZATION, " and ");
dump_generic_expr (MSG_MISSED_OPTIMIZATION, TDF_SLIM, nunits_vectype);
dump_printf (MSG_MISSED_OPTIMIZATION, "\n");
}
into a one-liner:
if (dump_enabled_p ())
dump_printf_loc (MSG_MISSED_OPTIMIZATION, vect_location,
"not vectorized: different sized vector "
"types in statement, %T and %T\n",
vectype, nunits_vectype);
Unlike regular pretty-printers, this one captures optinfo_item
instances for the formatted chunks as appropriate, so that when
written out to a JSON optimization record, the relevant parts of
the message are labelled by type, and by source location (so that
e.g. %G is entirely equivalent to using dump_gimple_stmt).
dump_printf and dump_printf_loc become marked with
ATTRIBUTE_GCC_DUMP_PRINTF, which the patch also implements.
