Subject: [Bug optimization/14863] [3.4 regression] unit-at-a-time causes miscompilation
Date: Wed, 07 Apr 2004 11:56:00 -0000 [thread overview]
Message-ID: <20040407115557.1001.qmail@sources.redhat.com> (raw)
In-Reply-To: <20040406114325.14863.rguenth@tat.physik.uni-tuebingen.de>
------- Additional Comments From 1319 at bot dot ru 2004-04-07 11:55 -------
I have just found that this bug can be triggered on/off using --param
large-function-insns=<something> option. Default value of this changed from
10000 before gcc-3_4-branch creation to 3000 shortly after.
All versions of 3.4.0 and 3.5.0 I tried (20040116..now) are OK with '-O1
-funit-at-a-time --param large-function-insns=10000' and all failed with '-O1
-funit-at-a-time --param large-function-insns=3000'.
