Bug ID: 78976
Summary: [7 Regression] FAIL: gfortran.dg/dependency_49.f90 and
gfortran.dg/transfer_intrinsic_1.f90
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
CC: jb at gcc dot gnu.org
Target Milestone: ---
Target: aarch64 arm
Hi,
Since commit r244003, I've noticed that 2 fortran tests now fail on arm and
aarch64 targets:
gfortran.dg/dependency_49.f90 -O scan-tree-dump-times original "__var_1" 4
gfortran.dg/transfer_intrinsic_1.f90 -O scan-tree-dump-times original
"MIN_EXPR" 1
I couldn't find the patch on gcc-patches, so I'm filing this bug report instead
of replying to the thread.
The commit message says:
PR 78534 Modify string copy to avoid -Wstringop-overflow warning
When the character length is changed from int to size_t the existing
algorithm causes a -Wstringop-overflow warning with -O1 on the
gfortran.dg/allocate_deferred_char_scalar_1.f03 testcase. This change
is committed separately from the character length size change in order
to make bisecting potential performance issues easier.
