convertUnionType()

Type convertUnionType ( hw::UnionType type, DataLayout & layout, LLVMTypeConverter & converter )

zextByOne()

Value zextByOne ( Location loc, ConversionPatternRewriter & rewriter, Value value )

static

Create a zext operation by one bit on the given value.

This is useful when passing unsigned indexes to a GEP instruction, which treats indexes as signed values, to avoid unexpected "sign overflows".
