Subject: [PATCH 0/2] Set REG_EQUAL when emitting arm_emit_movpair
Date: Sun, 28 Jun 2015 11:29:00 -0000	[thread overview]
Message-ID: <558FD9D5.9070703@linaro.org> (raw)

When we split constants with the arm_emit_movpair, we are not setting
the REG_EQUAL note. This patch attempts to do that.

Fist patch allow setting REG_EQUAL for ZERO_EXTRACT and handle that in
cse (where the src for the ZERO_EXTRACT needs to be calculated)
Second patch sets REG_EQUAL when emitting arm_emit_movpair.

Bootstrapped and regression tested on arm-none-linux (Chromebook) and
x86-64-linux-gnu with no new regression.

Is this OK for trunk,

Thanks,
Kugan
