Subject: [nvptx] Build libraries with misa=sm_30
X-Git-Tag: basepoints/gcc-13~851
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=07667c911b1827fb98a1b5da621d51d8fcf0409a;p=thirdparty%2Fgcc.git

[nvptx] Build libraries with misa=sm_30

In gcc-11, when  specifying -misa=sm_30, an executable may still contain sm_35
code (due to libraries being built with the default -misa=sm_35), so it won't
run on an sm_30 board.

Fix this by building libraries with sm_30, as was the case in gcc-5 to gcc-10.
