Bug ID: 87633
Summary: ice in compare_range_wit h_value, at vr-values.c:1702
Product: gcc
Version: 8.0
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 44845
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=44845&action=edit
gzipped C++ source code
For the attached C++ code, compiled by recent gcc trunk
and compiler flag -O2, does this:
during GIMPLE pass: evrp
../deps/v8/src/builtins.cc: In function ‘v8::internal::Object*
v8::internal::{an
onymous}::Slow_ArrayConcat(v8::internal::Arguments*,
v8::internal::Handle<v8::in
ternal::Object>, v8::internal::Isolate*)’:
../deps/v8/src/builtins.cc:4956:1: internal compiler error: in
compare_range_wit
h_value, at vr-values.c:1702
0xe9aae1 compare_range_with_value(tree_code, value_range*, tree_node*, bool*)
../../trunk/gcc/vr-values.c:1702
0xe9a518 vr_values::compare_name_with_value(tree_code, tree_node*, tree_node*,
b
ool*, bool)
../../trunk/gcc/vr-values.c:2106
The problem seems to occur between revisions 265077 and 265139.
I'll have my usual go at reducing the code.
