In my particular example, The DWARF information tells us the value is at the
following expression...
<11ac> DW_AT_GNU_call_site_value: 6 byte block: 8d ec 0 f6 4 2d
(DW_OP_breg29 (x29): 108; DW_OP_GNU_der

Thanks for confirming this behavior. There have been some changes to the DWARF
unwinding code that exposed this particular case. I'm guessing this will need
to go back to GDB for a fixup.

Here's a DWARF and asm dump from the same binary:

CC-ing ARM folks so they can assign this to whoever is more appropriate.

I've noticed this while investigating a GDB testsuite failure in
gdb.opt/inline-break.exp. Basically GDB runs into an internal error due to not

Did it even bootstrap properly? It shouldn't have been built in the first place
i guess, due to the signedness error of a particular chunk of code.
I did a fresh x86-64 bootstrap with the changes in and those

--- Comment #6 from Luis Machado ---
Would you please confirm the bootstrap is back to normal and declare it
resolved? I don't have permission to change its state.

--- Comment #1 from Luis Machado ---
Will do.
I've temporarily reverted the prefetcher changes since it caused x86 bootstrap
issues. I'll investigate this alongside it.

--- Comment #4 from Luis Machado ---
Reverted the offending changes for now.

There are a couple fixups needed in there. The second error you ran into was
already caught by gcc in the first comment.

Working on it.

Another bit of information...
On an early investigation (with an unoptimized compiler and unreduced
testcase), this bit in profile-count.h was causing the assertion to fail:
