Modified Files: src/sys/arch/powerpc/oea: altivec.c src/sys/arch/powerpc/powerpc: compat_16_machdep.c Log Message: - In vec_restore_from_mcontext() and vec_save_to_mcontext(), allows the mcontext argument to be NULL. - In sendsig_sigcontext(), don't set PSL_VEC in the saved MSR; we can't actually round-trip the AltiVec registers. At least get them saved into the PCB by calling vec_save_to_mcontext() (with a NULL mcontext argument). - In compat_16_sys___sigreturn14(), call vec_restore_from_mcontext() with a NULL mcontext argument, which will force any subsequent use of AltiVec to re-load the AltiVec registers from the PCB. This isn't ideal, but it's the best we can do with the limited capability of sigcontext. Fixes PR port-powerpc/56471.
