[PowerPC] Reject tdescs with VSX and no FPU or Altivec
|
||
|
|
|
||
|
|
Currently rs6000_gdbarch_init will accept a tdesc with the
|
||
|
|
"org.gnu.gdb.power.vsx" feature but without the
|
||
|
|
"org.gnu.gdb.power.altivec" or "org.gnu.gdb.power.fpu".
|
||
|
|
|
||
|
|
It isn't clear from the standard features documentation that these are
|
||
|
|
requirements. However, these tdescs would cause trouble in the VSX
|
||
|
|
pseudo-register functions, so this patch will cause them to be
|
||
|
|
rejected.
