[LLVMdev] Why llvm function name is different with . and ..

[罗勇刚(Yonggang Luo)]

  declare i8 @llvm.atomic.load.max.i8.p0i8( i8* <ptr>, i8 <delta> )
  declare i16 @llvm.atomic.load.max.i16.p0i16( i16* <ptr>, i16 <delta> )
  declare i32 @llvm.atomic.load.max.i32.p0i32( i32* <ptr>, i32 <delta> )
  declare i64 @llvm.atomic.load.max.i64.p0i64( i64* <ptr>, i64 <delta> )
  declare i8 @llvm.atomic.load.min.i8.p0i8( i8* <ptr>, i8 <delta> )
  declare i16 @llvm.atomic.load.min.i16.p0i16( i16* <ptr>, i16 <delta> )
  declare i32 @llvm.atomic.load.min.i32..p0i32( i32* <ptr>, i32 <delta> )
  declare i64 @llvm.atomic.load.min.i64..p0i64( i64* <ptr>, i64 <delta> )
  declare i8 @llvm.atomic.load.umax.i8.p0i8( i8* <ptr>, i8 <delta> )
  declare i16 @llvm.atomic.load.umax.i16.p0i16( i16* <ptr>, i16 <delta> )
  declare i32 @llvm.atomic.load.umax.i32.p0i32( i32* <ptr>, i32 <delta> )
  declare i64 @llvm.atomic.load.umax.i64.p0i64( i64* <ptr>, i64 <delta> )
  declare i8 @llvm.atomic.load.umin.i8..p0i8( i8* <ptr>, i8 <delta> )
  declare i16 @llvm.atomic.load.umin.i16.p0i16( i16* <ptr>, i16 <delta> )
  declare i32 @llvm.atomic.load.umin.i32..p0i32( i32* <ptr>, i32 <delta> )
  declare i64 @llvm.atomic.load.umin.i64..p0i64( i64* <ptr>, i64 <delta> )

Why in the llvm function name, some functions containing "..", but
others only contains only "."
Thanks.
