Subject: [PATCH, i386]: Committed: Fix PR target/35496
Date: Sun, 09 Mar 2008 13:38:00 -0000 [thread overview]
Message-ID: <47D3E838.8000204@gmail.com> (raw)
Hello!
We have to compute alignment of VECTOR_CST and INTEGER_CST constants via
ALIGN_MODE_128 in the same way as other ALIGN_MODE_128 data is aligned.

* config/i386/i386.c (ix86_constant_algnment): Compute alignment
using
ALIGN_MODE_128 for VECTOR_CST and INTEGER_CST in addition to
REAL_CST.
Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu
{,-m32}. Patch is committed to mainline, but I think that it should be
committed to 4.3 branch as well.
Uros.
