Arnd Bergmann <arnd at linaro dot org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |arnd at linaro dot org --- 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
