zextByOne()

static 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".
