Subject: 	* dev.scm: Add srcdir to %load-path.
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=eff6092b3e47b7613d2dffdaefd6cead215a38a8;p=cgen.git

	* dev.scm: Add srcdir to %load-path.

	* rtx-funcs.scm (subword): Mode of argument can be different
	than mode of result, so don't use OP0 to specify argument's mode.
