Bug ID: 90649
Summary: ICE tree check: accessed operand 4 of call_expr with 3
operands in generic_simplify_EQ_EXPR, at
generic-match.c:42857
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Affects versions down to at least gcc-5 :
(release versions need -Ofast)
$ cat z1.c
double sqrt ();
void f ()
{
!sqrt ();
}
$ gcc-10-20190526 -c z1.c -Ofast
z1.c: In function 'f':
z1.c:4:4: warning: too few arguments to built-in function 'sqrt' expecting 1
[-Wbuiltin-declaration-mismatch]
