Bug ID: 61367
Summary: Annoying rtx cost information in middle end dumps on
arm/aarch64 targets
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: amker.cheng at gmail dot com

zipped dump files.
Given a simple program like:
#define LEN (32000)
__attribute__((aligned(16))) float a[LEN],b[LEN];
int s174 (int M)
{
for (int i = 0; i < M; i++)
{
a[i+M] = a[i] + b[i];
}
return 0;
}
Build with O2/O3 -fdump-tree-all-details -fdump-rtl-all-details options. The
middle-end's dump files contain lots of rtx cost information, which messes up
with true dump information. The dump files of ivopt/cse2 are attached to show
this annoying problem.
