Subject: gas: stub out sframe-opt.c functions when SFrame is not supported
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c2db59a7a276a77eef1e70f545fb4344cc7696a0;p=thirdparty%2Fbinutils-gdb.git

gas: stub out sframe-opt.c functions when SFrame is not supported

Much like everything in gen-sframe.c, these functions are supposed to
never be reached when SFrame isn't supported by a target. Adding
respective assertions reduces code size for such targets, while at the
same time adding consistency checking for targets which optionally
support the feature.
