--- Comment #14 from Arnd Bergmann <arnd at linaro dot org> ---
I got the same output while building the linux kernel defconfig today, reduced
to this minimal test case:
$ cat test.c
long a, b;
int fn1() {
char *c = (void *)b;
while (1) {
const long d = *c = d;
do
a++;
while (a == 5);
}
}
$ ia64-linux-gcc -O3 -c test.c
during RTL pass: mach
lz4_decompress.c:10:1: internal compiler error: in sel_target_adjust_priority,
at sel-sched.c:3334
10 | }
Reproduced both with 9.2 and current HEAD
$ ia64-linux-gcc --version
ia64-linux-gcc (GCC) 9.2.1 20200211
