Bug #: 56657
Summary: [GCC 4.6/4.7] ICE - error: unrecognizable insn.
Classification: Unclassified
Product: gcc
Version: 4.7.2
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: nkbj1970@hotmail.com
Target: *-*-mingw32
Created attachment 29693
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29693
Test case.
I got this ICE when cross-building UFRaw (http://ufraw.sourceforge.net) for
Windows using MXE (http://mxe.cc). I have tried GCC 4.7.2, 4.7.0, 4.6.3, and
4.6.0. All crash with the same error. GCC 4.5.4 works.
The output is:
CC ufraw_writer.o
ufraw_writer.c: In function 'ufraw_write_image':
ufraw_writer.c:790:1: error: unrecognizable insn:
(insn 214 213 215 19 (set (mem/v/f/c:SI (plus:SI (reg/f:SI 54
virtual-stack-vars)

(const:SI (plus:SI (symbol_ref:SI ("_iob") [flags 0x440] <var_decl
0x2b94ad99ed20 _iob>)
(const_int 32 [0x20])))) ufraw_writer.c:334 -1

Please submit a full bug report,

make[2]: *** [ufraw_writer.o] Error 1
I have attached a small test case which also shows the error compiled with
'i686-pc-mingw32-g++ -c insn.cc' (it happens for both c and c++ code):
insn.cc: In function 'void f()':
insn.cc:3:29: error: unrecognizable insn:

Doh. I forgot to attach the output from '-save-temps'.
I am not sure about the 'middle-end' component. Please change to the correct
one if I am wrong.
