Message:
This is the first patch breaking down issue 23156006 (improving lithium
register
constraints).
This patch does not contain any contentious changes (changes to Lithium
framework), these will be subject of a dedicated patch later. In the mean
time
we will submit patches improving specific lithium instructions (e.g. using
less
registers, not corrupting inputs, tweaked code sequences).
Description:
ARM: Improve integer multiplication.
