Title:
internal compiler error: in fixup_reorder_chain,, at cfgrtl.c:3336
To
$ cat notify.i
_Bool a;
fn1(unsigned int p1) {
unsigned int b = a ? p1 : 0;
if (p1 || b)
fn2(0, p1, b);
}
$ gcc -c -O1 -fno-if-conversion notify.i
$ gcc -c -O1 notify.i
notify.i: In function 'fn1':
notify.i:6:1: internal compiler error: in fixup_reorder_chain, at cfgrtl.c:3336
}
^
workaround is to build the file with -fno-if-conversion.

Please see the gcc-4.8 crash log on trusty/arm64, which includes the gcc

Hi Tom,
Can you please help us isolate a reduced test case for this issue,
preferably with a single preprocessed source file and a minimal set of
gcc flags necessary to reproduce it?
