[Bug c/13395] New: ICE during bootstrap with BOOT_CFLAGS="-O2 -g -fnew-ra -ftracer"

[v dot haisman at sh dot cvut dot cz]

I get this ICE while bootstrapping with those two -f* options. I didn't try any
other combination of these. Preprocessed source is attached.

It is the -fnew-ra option that makes it crash.

Here's a reduced testcase that crashes mainline with "gcc -O2 -fnew-ra"

=============================================
int foo();
int bar()  { return foo(); }
void baz() { bar; }
=============================================

The testcase compiles fine on the 3.3 branch.

New-ra is most likely not going to work with the mainline that well anyways, pushing to 3.5.

Closing as wiill not fix as new-ra was removed from the mainline.
