Subject: ceil, rint, round, trunc, *-ieee: Remove support for IRIX.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c434544ed703950f49b32dcc5eec5047d0db8221;p=thirdparty%2Fgnulib.git

ceil, rint, round, trunc, *-ieee: Remove support for IRIX.

* m4/minus-zero.m4 (gl_FLOAT_MINUS_ZERO_CODE, gl_DOUBLE_MINUS_ZERO_CODE,
gl_LONG_DOUBLE_MINUS_ZERO_CODE): Remove code for IRIX cc.
* lib/ceil.c (MINUS_ZERO): Likewise.
* lib/rint.c (MINUS_ZERO): Likewise.
* lib/round.c (MINUS_ZERO): Likewise.
* lib/trunc.c (MINUS_ZERO): Likewise.
