From: Janis Johnson <janis187@us.ibm.com> To: gcc-gnats@gcc.gnu.org, gcc-prs@gcc.gnu.org, gcc-bugs@gcc.gnu.org, nobody@gcc.gnu.org, ebuddington@wesleyan.edu Cc: Subject: Re: middle-end/8808: [3.2/3.3 regression] Internal compiler error in extract_constrain_insn_cached Date: Wed, 18 Dec 2002 14:14:36 -0800 The regression reported in PR middle-end/8808 showed up starting with this patch: Tue Feb 13 13:31:33 CET 2001 Jan Hubicka <jh@suse.cz> * i386.c (print_reg): Use ANY_FP_REG instead of FP_REG * i386.h (MASK_128BIT_LONG_DOUBLE): Renumber ... * i386.md (pushsf, movsf): Support SSE. ... Output from the compiler (current mainline): 8808.c: In function `g': 8808.c:6: error: insn does not satisfy its constraints: (insn 18 23 28 (nil) (set (mem:DI (plus:SI (reg/f:SI 6 ebp) (const_int -8 [0xfffffff8])) [0 S8 A8]) (reg/v:DI 29 rmm0)) 59 {*movdi_2} (nil) (nil)) 8808.c:6: internal compiler error: in extract_constrain_insn_cached, at recog.c:2092 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions. The test compiles with -march=pentium4; perhaps the compiler should validate asm instructions against the target architecture and give a meaningful error message in this case. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=8808
