Subject: [Bug tree-optimization/39041]  New: ICE on valid during vrp2
Date: Fri, 30 Jan 2009 10:50:00 -0000	[thread overview]
Message-ID: <bug-39041-10026@http.gcc.gnu.org/bugzilla/> (raw)

The attached file causes an ICE with gcc-4.3.2 and gcc-4.3.3 on at least two
targets (ix86 Linux and Blackfin) when compiled with -O2.

bug.i: In function 'foo':
bug.i:18: internal compiler error: in get_addr_dereference_operands, at
tree-ssa-operands.c:1698

This happens during the vrp2 pass:

bernds@beaker /local/blackfin/b-4.3/gcc $ tail bug.i.115t.vrp2 
prephitmp.29_38: [0, 1]
SMT.36_57: VARYING



Substituing values and folding statements

Folded statement: pretmp.28_29 = *D.1312_16;
            into: pretmp.28_29 = *&cpumask.bits[0];
