The attached patch avoids considering debug_insn when calculating SCCs.
With this change the existence of debug_insn does not influence

This has been fixed by revision 172603 and now the thresholds are
the same with/without -flto. For the fine tuning I have posted
some results on pr48636.

The compiler ICEs on the call to a function returning a discriminated record

node between two types.

When changing the max value to 2, any value that is greater than

Thanks Diego for committing this patch.
Yes, I would like to submit the patch to trunk. The reason is for this

Hi Folks,
This patch implements the adjustments required for the various rounding modes as
stated in the Fortran Standard F2008, paragraph 10.7.5.2.2. In the process of
testing this patch we have found another bug related to D and E editing which is
now PR48651. In the meantime, this regress
PR45074 is a case where expand_absneg_bit needs to decompose a
multi-word negation operation into separate word_mode operations.
The target of the operation is a global FP register variable.
For various reasons, CANNOT_CHANGE_MODE_CLASS forbids changes
from DFmode to SImode for FP registers, so a
PR 45074 showed up a rather embarrassing oversight in the MIPS backend:
global registers were still being treated as call-saved.
Fixed with the attached patch. Tested on mips64-linux-gnu and applied.

this (partially) fixes the LTO bootstrap failure with Ada enabled on the
mainline. The problem is an ICE whose origin is as follows:
1. during LTO stage, copy-prop eliminates a DECL_IN_CONSTANT_POOL variable
