Bug ID: 57980
Summary: gcc 4.8.1 -foptimize-sibling-calls -O1 ICE in
build_int_cst_wide, at tree.c:1210
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: zeccav at gmail dot com
From a testsuite code, fpsub32s.c,
compiling it with -O1 -foptimize-sibling-calls
I get an ICE in build_int_cst_wide, at tree.c:1210.
As in the following:
/*gcc 4.8.1 -foptimize-sibling-calls -O1 ICE in build_int_cst_wide, at
tree.c:1210*/
typedef int vec32 __attribute__((vector_size(4)));
vec32 f(void);
vec32 bar(void)
{
return - f ();
}
/*
gccerr3.c: In function ‘bar’:
gccerr3.c:9:1: internal compiler error: in build_int_cst_wide, at tree.c:1210
}

In process_assignment (tree-tailcall.c):
if (FLOAT_TYPE_P (TREE_TYPE (op0)))
*m = build_real (TREE_TYPE (op0), dconstm1);
else
*m = build_int_cst (TREE_TYPE (op0), -1);
could be replaced by:
*m = build_minus_one_cst (TREE_TYPE (op0));
unless we want to return false for some types. The same issue likely exists for
the MINUS_EXPR case below.
