[Bug bootstrap/18371] New: array subscript out of range

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hello there,

I just tried to compile gcc 343 with the Intel C 8.1 compiler.
The Intel compiler said

../../src/gcc-3.4.3/gcc/config/i386/i386.c(10626): warning #175: subscript out
of range
../../src/gcc-3.4.3/gcc/config/i386/i386.c(10629): warning #175: subscript out
of range

The source code is

	long l[3];

	/* ... */

	+ ((((HOST_WIDE_INT) l[3]) << 31) << 1),
	/* ... */
	parts[1] = immed_double_const (l[2], l[3], DImode);

In fact, l[ 3] does not exist. Suggest code re-work.
