Summary: [8/9 Regression] ICE in expand_call, at calls.c:4229
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: gs...@t-online.de
Target Milestone: ---
Started with gcc-8 (before 20180525) :
$ cat z1.c
struct S {
long a[0] __attribute__ ((aligned (32)));
};
void foo ()
{
struct S b;
f (8.0L, b);
}
$ gcc-9-20190331 -c z1.c
z1.c: In function 'foo':
z1.c:7:3: warning: implicit declaration of function 'f'
[-Wimplicit-function-declaration]
7 | f (8.0L, b);
| ^
z1.c:7:3: note: the ABI for passing parameters with 32-byte alignment has
changed in GCC 4.6
7 | f (8.0L, b);
| ^~~~~~~~~~~
