when i suggested that you do a build with all of the checking turned on,
i wanted you to this without you new code in it.there is a good
possibility that the problem is that your port is generating bad rtl.
Also, you should generate a debuggable compiler so that the line numbers

Hi,
I have problems compiling xalan as part of spec2006 benchmark for aarch64, both
native and cross.
The issue arises when both -flto and -fprofile-generate are enabled during LTO.
Compiling with the same flags for x86 has no problem.
Also other projects for aarch64 compile with -flto and -fprof

It is generally as easy as just adding the problem and calling
df_analyze. You tend to get into trouble if the rtl is not good, i.e.
there is improper sharing or other violations of the canonical rtl
rules. DF does not like improperly shared rtl and it has not been
uncommon for port specific

Hi, in order to fix PR64331 I tried to implement new target-specific passes
whose sole purpose is to recompute REG_DEAD notes.
The avr BE relies on correct dead notes which are used in
avr.c:reg_unused_after which uses dead_or_set_p. avr BE needs correct dead
notes in ADJUST_INSN_LENGTH, get_
