Subject: [Bug c++/101511] New: ice in query_relation, at value-relation.cc:879
Date: Mon, 19 Jul 2021 13:54:52 +0000 [thread overview]
Message-ID: <bug-101511-4@http.gcc.gnu.org/bugzilla/> (raw)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101511
Bug ID: 101511
Summary: ice in query_relation, at value-relation.cc:879
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Created attachment 51171
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51171&action=edit
gzipped C++ source code
The attached C++ code does this with recent gcc:
$ /home/dcb/gcc/results/bin/gcc -c -O2 -w bug739.cc
during GIMPLE pass: evrp
/home/dcb34/rpmbuild/BUILD/glm-0.9.9.8/test/ext/ext_scalar_integer.cpp: In
funct
ion ‘int nextMultiple::test_uint() [with T = unsigned int]’:
/home/dcb34/rpmbuild/BUILD/glm-0.9.9.8/test/ext/ext_scalar_integer.cpp:677:1:
in
ternal compiler error: in query_relation, at value-relation.cc:879

0x8caf23 relation_oracle::query_relation(basic_block_def*, tree_node*,
tree_node
*)
../../trunk.git/gcc/value-relation.cc:879
0x15ec545 range_query::query_relation(gimple*, tree_node*, tree_node*, bool)
../../trunk.git/gcc/value-query.cc:475
The bug first seems to occur sometime between git hash b4e21c80462682c4
and 7dcf139a2b8e1c53
I will have my usual go at reducing the code and I might even
have a go at finding the git revision that causes the problem.
