	* stdlib/strtod_l.c (INTERNAL (__STRTOF)): Clear the rest of retval,
	not just one limb if RETURN_LIMB_SIZE > 2.  Fix shifting up if
	RETURN_LIMB_SIZE > 2.

	* stdio-common/printf_fp.c (__printf_fp): For IEEE quad long double
	on 32-bit architectures reserve 8 limbs instead of 4.

@ -45,15 +45,15 @@ but it's better to pretty print it first. "gen-libm-test.pl" has an option
to generate a pretty-printed and sorted new ULPs file from the output
of the test drivers.
To generate a new "libm-test-ulps" file, you can execute for example:
To generate a new "libm-test-ulps" file, first remove "ULPs" file in the
current directory, then you can execute for example:
test-double -u --ignore-max-ulp=yes
This generates a file "ULPs" with all double ULPs in it, ignoring any
previous calculated ULPs.
Now move this away, e.g. "mv ULPs allULPs" and generate the ULPs
for all other formats and concat all ULP files together (e.g. "cat
ULPs >> allULPs"). As final step run "gen-libm-test.pl" with the file
as input and ask to generate a pretty printed output in the file "NewUlps":
gen-libm-test.pl -u allULPs -n
Now generate the ULPs for all other formats, the tests will be appending
the data to the "ULPs" file. As final step run "gen-libm-test.pl" with the
file as input and ask to generate a pretty printed output in the file "NewUlps":
gen-libm-test.pl -u ULPs -n
Now you can rename "NewUlps" to "libm-test-ulps" and move it into
sysdeps.
