Description prathamesh3492 2018-11-07 12:59:30 UTC
Hi,
It seems lots of tests are failing with bootstrap build of arm-linux-gnueabihf
with following ICE:

during GIMPLE pass: ldist
/home/prathamesh.kulkarni/gnu-toolchain/gcc/tcwg-319-4/gcc/gcc/testsuite/c-c++-common/torture/pr53505.c: In function 'main':

0x66416d execute
        ../../gcc/gcc/tree-loop-distribution.c:3133

Several tests fail with above ICE, like pr53505.c,
20131115-1.c, 20181024-1.c etc.

Thanks,

Is this a duplicate of https://gcc.gnu.org/bugzilla/show_bug.cgi?id=87899 ?
Comment 2 prathamesh3492 2018-11-07 13:03:42 UTC
Likely yes, thanks for the pointer! I will mark this as dup.

Thanks,
Prathamesh
