Builds a constant of a sequential LLVM type type, potentially containing other sequential types recursively, from the individual constant values provided in constants.
shape contains the number of elements in nested sequential types. Reports errors at loc and returns nullptr on error.

static |
Attempts to add an attribute identified by key, optionally with the given value to LLVM function llvmFunc.
Reports errors at loc if any. If the attribute has a kind known to LLVM IR, create the attribute of this kind, otherwise keep it as a string attribute. Performs additional checks for attributes known to have or not have a value in order to avoid assertions inside LLVM upon construction.

static |
Convert a dense elements attribute to an LLVM IR constant using its raw data storage if possible.
This supports elements attributes of tensor or vector type and avoids constructing separate objects for individual values of the innermost dimension. Constants for other dimensions are still constructed recursively. Returns null if constructing from raw data is not supported for this type, e.g., element type is not a power-of-two-sized primitive. Reports other errors at loc.

|
static |
Attaches the attributes listed in the given array attribute to llvmFunc.
Reports error to loc if any and returns immediately. Expects attributes to be an array attribute containing either string attributes, treated as value-less LLVM attributes, or array attributes containing two string attributes, with the first string being the name of the corresponding LLVM attribute and the second string beings its value. Note that even integer attributes are expected to have their values expressed as strings.

A helper method to decide if a constant must not be set as a global variable initializer.
For an external linkage variable, the variable with an initializer is considered externally visible and defined in this module, the variable without an initializer is externally available and is defined elsewhere.

Only integer, float, pointer and endianness entries are currently supported.
