Author: emaste Date: Mon Nov 26 19:29:18 2018 New Revision: 340991 URL: https://svnweb.freebsd.org/changeset/base/340991 Log: stand/i386/libi386: rename .s file to .S to use Clang IAS As part of the migration away from obsolete binutils we want to retire GNU as. Most assembly files used on amd64 have a .S extension and are assembled with Clang's Integrated Assembler (IAS); rename pxetram.s to .S to use IAS as well. The generated .text is identical (the entire .o file is not, as Clang adds debug info.)
