Summary: After r320749, Assertion failed:
(!NodePtr->isKnownSentinel()), function operator*,
file include/llvm/ADT/ilist_iterator.h, line 140.
Product: new-bugs
Version: trunk
Hardware: PC

As reported in https://bugs.freebsd.org/225275, compiling the textproc/groonga
and www/nginx ports for armv6 asserts with:
Assertion failed: (!NodePtr->isKnownSentinel()), function operator*, file
include/llvm/ADT/ilist_iterator.h, line 140.
This regressed after https://reviews.llvm.org/rL320749, which is a fix for bug
34603.
Minimized test case:
/* clang -cc1 -triple armv6kz -S -target-cpu arm1176jzf-s -O2
ngx_inet-minimized.c */
int a;
int c() {
int b;
__asm("" : "+r"(b));
return b;
}
short d() {
switch (a) {
case 0:
return c();
case 1:
return 0;
default:
return c();
}
}
