◆ checkWidthChangeCast()

template<template< typename > class WidthComparator, typename... ElementTypes>
static bool checkWidthChangeCast ( TypeRange  inputs,

◆ convertArithRoundingModeToLLVMIR()

static llvm::RoundingMode convertArithRoundingModeToLLVMIR ( RoundingMode  roundingMode)

Equivalent to convertRoundingModeToLLVM(convertArithRoundingModeToLLVM(roundingMode)).

Not possible to implement as chain of calls as this would introduce a circular dependency with MLIRArithAttrToLLVMConversion and make arith depend on the LLVM dialect and on translation to LLVM.
