Bug ID: 66648
Summary: [4.9/5/6 regression] incorrect memcpy expansion with
unrolled_loop strategy at -O2
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ebotcazou at gcc dot gnu.org
Target Milestone: ---
Target: x86_64-*-linux
Created attachment 35840
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35840&action=edit
Testcase
One of the numerous paths of ix86_expand_set_or_movmem using the unrolled_loop
strategy can generate wrong code (buffer overflow) at -O2, when VRP is able to
compute a minimum copying size.
Compile and run the attached testcase with -O2
-mstringop-strategy=unrolled_loop -mtune=nocona on a x86-64/Linux machine.

Sorry, not the same issue as PR 66358. It seems more like another bug of PR
65979, which is a buggy peephole optimization.

We have to emit check for main loop execution UNLESS we guarantee that min_size
is at least equal to size_needed. In this testcase, VRP declared minimum
copying size, and after unaligned prologue adjustment, min_size was still
non-zero. The !min_size check didn't account for the case that min_size can be
non-zero, but still less than size_needed.

--- Comment #26 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> ---
One more datapoint on the .smod / .mod issue.
I ran into the first package that fails to build with 6.0 because of this.
libxc (version 2.2.2, Tobias Burnus actually being one of the authors), relies
on a configure macro named ax_cv_f90_modext this macro now leads in the
Makefile to :
[...]
am__untar = $${TAR-tar} xf -
ax_cv_f90_modext = mod
smod
bindir = ${exec_prefix}/bin
[...]
which leads to an obvious:> make -j
Makefile:319: *** missing separator. Stop.
While arguably this is a bug in the ax_cv_f90_modext macro, it might be
indicative of possible problems 'in the wild'.
However, I do like the idea of having only public info in the .mod, and hence
improving the recompilation cascade problem.
