x86: Disallow -mindirect-branch=/-mfunction-return= with -mcmodel=large
Since the thunk function may not be reachable in large code model,
-mcmodel=large is incompatible with -mindirect-branch=thunk,
-mindirect-branch=thunk-extern, -mfunction-return=thunk and
-mfunction-return=thunk-extern. Issue an error when they are used with
-mcmodel=large.
gcc/
* config/i386/i386.c (ix86_set_indirect_branch_type): Disallow
-mcmodel=large with -mindirect-branch=thunk,
-mindirect-branch=thunk-extern, -mfunction-return=thunk and
-mfunction-return=thunk-extern.
* doc/invoke.texi: Document -mcmodel=large is incompatible with
-mindirect-branch=thunk, -mindirect-branch=thunk-extern,
-mfunction-return=thunk and -mfunction-return=thunk-extern.
