altivec_pim_warnings

Controls how the compiler translates literal values for AltiVec vectors.

#pragma altivec_pim_warnings on | off | reset
  

When this pragma is on , the compiler follows the syntax rules described in AltiVec™ Technology Programming Interface Manual ("PIM") to specify literal values for vector objects. This syntax specifies these requirements:

• vector values must be enclosed in parentheses
• vector values must be preceded by a type specifier

When this pragma is off , the compiler expects a style more consistent with C source code conventions:

• vector values must be enclosed in braces
• vector values do not need to be preceded by a type specifier

Example of using altivec_pim_warnings shows an example.

#pragma altivec_pim_warnings on
vector signed int vsi1 = (__vector signed int)(1, 2, 3, 4);

#pragma altivec_pim_warnings off
vector signed int vsi2 = {1, 2, 3, 4};
