            Bug ID: 84760
           Summary: Finish implementation of __builtin_altivec_lvx_v1ti
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kelvin at gcc dot gnu.org
  Target Milestone: ---

The gcc/config/rs6000/rs6000-builtin.def source file contains an entry that
introduces the enumeration constant ALTIVEC_BUILTIN_LVX_V1TI and the built-in
function __builtin_atlivec_lvx_v1ti:

BU_ALTIVEC_X (LVX_V1TI,         "lvx_v1ti",         MEM)

The remainder of the implementation, which is required to define the prototype
for this function and to connect the function with its implementation, is
missing.  This was an apparent oversight at the time that this definition was
introduced.  T
