Hello,
we are working on a project to make module debugging for the Linux
kernel easier. We want to improve it in such a way that gdb
automatically loads the symbols of modules. However, we are facing the
following difficulties: gdb needs to know all section of the ELF files.

Hello,
I'm trying to get to a point where the CFG is useable even in the
delay-slot filling pass (dbr_schedule) and I'm currently stuck on a
transformation that the PA port does if -mno-big-switch is in effect.
With !TARGET_BIG_SWITCH, the PA port explodes a JUMP_TABLE_DATA to
real code, i.e.

The tree combiner/forward propagator is missing opportunities to
collapse sequences like this:
_15 = _12 ^ _14;
if (_15 != 0)
Into:
if (_12 != _14)
The tree combiner/forward propagator builds this tree:
x ^ y
Then passes it to canonicalize_cond_expr_cond That is not suitable

bb 6:

Assume _23 and changed_17 have integer types wider than a boolean, but
VRP has determined they have a range [0..1].
We should be turning that into:

Hello,
The existing documentation for SEQUENCE still states it is used for
DEFINE_EXPAND sequences. I think I wasn't even hacking GCC when that
practice was abandoned, and in the mean time some other uses of
SEQUENCE have appeared in the compiler. So, a long-overdue
documentation update.

I don't think the SSA_NAME_OCCURS_IN_ABNORMAL_PHI test is necessary,
get_value_range() will simply return a !VR_RANGE.
