Bug ID: 61887
Summary: vect.exp UNRESOLVED tests
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
Assignee: unassigned at gcc dot gnu.org
Reporter: m.zakirov at samsung dot com
I found that some tests from vect.exp has status UNRESOLVED in cureent compiler
version due to dissynchronization of compiler dumpers and tests check.
Example:
Test bb-slp-10.c awaits for name
bb-slp-10.c.124t.slp
but it gets this
bb-slp-10.c.124t.slp2
Open bb-slp-10.c
Change "slp" to "slp2" in
...
/* { dg-final { scan-tree-dump-times "unsupported alignment in basic block." 1
"slp" { xfail vect_element_align } } } */
/* { dg-final { scan-tree-dump-times "basic block vectorized using SLP" 1 "slp"
{ target vect_element_align } } } */
Test will pass or at least it won't have UNRESOLVED status.
Another UNRESOLVED example vect-105-big-array.c and generaly all tests with
scan-tree-dump-times and -flto option.
-flto makes gcc to create file with name
vect-105-big-array.exe.ltrans0.114t.vect
Which is obviosly not supported too.
Configuration:
/home/mzakirov/proj/gcc_unalign/build.arm.cortex-a15/sources/gcc_1/configure
--build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu
--target=arm-linux-gnueabi --with-interwork --enable-long-long
--enable-languages=c,c++,fortran --enable-shared --with-gnu-as --with-gnu-ld
--with-arch=armv7-a
Run tests:
make -k check RUNTESTFLAGS='vect.exp'
--Marat
