[Bug target/16357] New: ICE copying 7 bytes between extern char[]s

[rsandifo at gcc dot gnu dot org]

Compiling the following:

-----------------------------------------------------------
extern char foo[], bar[];
void f (void) { memcpy (foo, bar, 7); }
-----------------------------------------------------------

with mipsisa64-elf causes an ICE:

-----------------------------------------------------------
/tmp/foo.c: In function `f':
/tmp/foo.c:2: error: PRINT_OPERAND, invalid operand for relocation
(const:DI (plus:DI (symbol_ref:DI ("bar") [flags 0x40] <var_decl 0x401c2e80 bar>)
        (const_int 6 [0x6])))
/tmp/foo.c:2: internal compiler error: in print_operand_reloc, at
config/mips/mips.c:5624
-----------------------------------------------------------

The problem is due to incorrect mode usage in mips_block_move_straight.
Testing a fix now.
