Please see stack_adjust function, where emit_move_insn is used to move an immediate to r10. However, emit_move_insn with (const_int -32812) generates= two insn sequence: (insn 952 123 953 2 (set (reg:SI 10 r10) (const_int -65536 [0xffffffffffff0000])) ../../../../../../rtems/c/src/../../cpukit/libdl/fastlz.c:167 -1 (nil)) (insn/f 953 952 954 2 (set (reg:SI 10 r10) (ior:SI (reg:SI 10 r10) (const_int 32724 [0x7fd4]))) ../../../../../../rtems/c/src/../../cpukit/libdl/fastlz.c:167 -1 (expr_list:REG_EQUAL (const_int -32812 [0xffffffffffff7fd4]) (nil))) However: /* r10 is caller saved so it can be used as a temp reg. */ rtx r10; r10 =3D gen_rtx_REG (word_mode, 10); insn =3D emit_move_insn (r10, GEN_INT (amount)); if (amount < 0) RTX_FRAME_RELATED_P (insn) =3D 1; emit_move_insn returns only the *last* insn of the sequence (insn 953 in the above dump). (insn 952) doesn't get RTX_FRAME_RELATED_P flag set - please n= ote lack of /f modifier - and consequently dwarf2out_frame_debug_expr trips in = Rule 7 due to unknown cfa_temp.reg (which would be otherwise initialized in insn 952, following Rule 6). So, considering that emit_move_insn can generate a sequence of insns, but o= nly the last insn is returned as a return value of a function, insn =3D emit_move_insn (r10, GEN_INT (amount)); RTX_FRAME_RELATED_P (insn) =3D 1; is not the correct way to set /f flags to all insn of the generated sequenc= e. >>From gcc-bugs-return-473921-listarch-gcc-bugs=gcc.gnu.org@gcc.gnu.org Mon Jan 19 22:27:43 2015 Return-Path: Delivered-To: listarch-gcc-bugs@gcc.gnu.org Received: (qmail 1773 invoked by alias); 19 Jan 2015 22:27:42 -0000 Mailing-List: contact gcc-bugs-help@gcc.gnu.org; run by ezmlm Precedence: bulk List-Id: List-Archive: List-Post: List-Help: Sender: gcc-bugs-owner@gcc.gnu.org Delivered-To: mailing list gcc-bugs@gcc.gnu.org Received: (qmail 1676 invoked by uid 48); 19 Jan 2015 22:27:33 -0000 From: "jakub at gcc dot gnu.org" To: gcc-bugs@gcc.gnu.org Subject: [Bug target/64669] [5 Regression] aarch64-linux profiledbootstrap failure Date: Mon, 19 Jan 2015 22:27:00 -0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: gcc X-Bugzilla-Component: target X-Bugzilla-Version: 5.0 X-Bugzilla-Keywords: X-Bugzilla-Severity: normal X-Bugzilla-Who: jakub at gcc dot gnu.org X-Bugzilla-Status: ASSIGNED X-Bugzilla-Priority: P3 X-Bugzilla-Assigned-To: jiwang at gcc dot gnu.org X-Bugzilla-Target-Milestone: 5.0 X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: 7bit X-Bugzilla-URL: http://gcc.gnu.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-SW-Source: 2015-01/txt/msg01915.txt.bz2 Content-length: 149 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64669 --- Comment #3 from Jakub Jelinek --- That was the --disable-werror.
