Bug #: 50931
Summary: [avr] Support a 24-bit scalar integer mode
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target

Target: avr
In order to support the upcoming named address spaces, a 24-bit wide mode is
needed because 32-bit mode is too expensive.
As a byproduct, 24-bit arithmetic can be exposed to user for general integer
arithmetic by means of built-in types. This is advantageous if 32-bit
arithmetic is too expensive and 16-bit arithmetic is too unprecise.
