    This class of intrinsics is designed to be generic and has +no specific purpose.

    +
    + + +
    + 'llvm.var.annotation' Intrinsic +
    + +
    + +
    Syntax:
    +
    +  declare void @llvm.var.annotation(i8* <val>, i8* <str>)
+
    + +
    Overview:
    + +

    +The 'llvm.var.annotation' intrinsic +

    + +
    Arguments:
    + +

    +The first argument is a pointer to a value, and the second is a pointer to a +global string. +

    + +
    Semantics:
    + +

    +This intrinsic allows annotation of local variables with arbitrary strings. +This can be useful for special purpose optimizations that want to look for these + annotations. These have no other defined use, they are ignored by code + generation and optimization. +
