Subject: s390: Use arch14 instead of z16 for -march=native.
X-Git-Tag: basepoints/gcc-14~758
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=da5adab2ae046bed0e2b72466f439f023f697433;p=thirdparty%2Fgcc.git

s390: Use arch14 instead of z16 for -march=native.

When compiling on a system where binutils do not yet support the 'z16'
name assembling fails with -march=native on a z16 machine.
Currently, this is interpreted as -march=z16.  This patch uses -march=arch14
instead.

gcc/ChangeLog:

	* config/s390/driver-native.cc (s390_host_detect_local_cpu): Use
	arch14 instead of z16.
