commit 7e1e68b45c4f2e048213cffa8ccd42a1e5c4fec6
Author: Joseph Myers <joseph@codesourcery.com>

    Rework gen-libm-test.pl input/output handling.
    
    This patch reworks how input and output files are specified for
    gen-libm-test.pl.
    
    Previously, the script had names of various inputs and outputs
    hardcoded, with a -o option to specify an output directory.  This
    patch replaces this with all inputs and outputs being specified
    explicitly as the arguments of options passed to the script.  Outputs
    are only generated if the relevant option is passed, and only the
    processing required for the indicated outputs is done.  The Makefile
    is made to pass options for generating libm-test-ulps.h in a separate
    invocation of gen-libm-test.pl from that generating libm-test.c.
    
    This is all in preparation for splitting up libm-test.inc and
    auto-libm-test-out and running tests separately for each function,
    when gen-libm-test.pl will be run separately for each function to
    generate the .c file but only once to generate libm-test-ulps.h (and
    those runs will be able to be in parallel).
    
    Tested for x86_64.  The generated libm-test.c and libm-test-ulps.h are
    identical before and after the patch.  Also tested the "make
    regen-ulps" case.

    	($opt_C): Likewise.
    	($opt_H): Likewise.
    	(-n): Make option take argument and use it as NewUlps output.
    	(-a): New option.  Use its argument for auto-libm-test-out input.
    	(-c): New option.  Use its argument for libm-test.inc input.
    	(-C): New option.  Use its argument for libm-test.c output.
    	(-H): New option.  Use its argument for libm-test-ulps.h output.
    	(top level): Only process inputs needed to generate outputs
    	specified by command-line options.  Only generate outputs
    	specified by command-line options.
    	* math/README.libm-test: Update example gen-libm-test.pl command.
    	* math/Makefile ($(objpfx)libm-test.stmp): Update gen-libm-test.pl
    	commands.
    	(regen-ulps): Likewise.
