Subject: ia64: define new get-rounding-mode.h header
X-Git-Tag: glibc-2.17~522
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=15055a1cd7e2c249093a5f6d57eca817767d8b85;p=thirdparty%2Fglibc.git

ia64: define new get-rounding-mode.h header

The new strtod function wants rounding information from the C lib, so
move the guts of the ia64 version into a header file for it to use.
