This is the bootstrap failure of GCC 11 on MinGW64 configured with --enable-
tune=nocona. The bottom line is that SEH does not support CFI for epilogues
but the x86 back-end nevertheless attaches it to instructions, so we have to
filter it out and this is done by detecting the end of the prologue by means
of the NOTE_INSN_PROLOGUE_END note.
But the compiler manages to generate a second epilogue before this note in
the RTL stream and this fools the aforementioned logic. The root cause is
cross-jumping, which inserts a jump before the end of the prologue, in fact
just before the note; the rest (CFG cleanup, BB reordering, etc) is downhill
from there.

* cfgcleanup.c (try_crossjump_to_edge): Also skip end of prologue
and beginning of function markers.

This removes CC0 and all directly related infrastructure.
CC_STATUS, CC_STATUS_MDEP, CC_STATUS_MDEP_INIT, and NOTICE_UPDATE_CC
are deleted and poisoned. CC0 is only deleted (some targets use that
name for something else). HAVE_cc0 is automatically generated, and we
no longer will do that after this patch.
CC_STATUS_INIT is suggested in final.c to also be useful for ports that
are not CC0, and at least arm seems to use it for something. So I am
leaving that alone, but most targets that have it could remove it.

The following testcase fails with -fcompare-debug. The problem is that
outgoing_edges_match behaves differently between -g0 and -g, if
some load/store with REG_EH_REGION is followed by DEBUG_INSNs, the
REG_EH_REGION check is not done, while when there are no DEBUG_INSNs, it is
done.
We already compute last1 and last2 as BB_END (bb{1,2}) with skipped debug
insns and notes, so this patch just uses those.

This is a follow-up to
https://gcc.gnu.org/ml/gcc-patches/2019-11/msg00919.html (r278095).
Dominance info is deleted even if we don't perform jump threading.
Since the whole point of this pass is to perform jump threading (other
cleanups are not valuable at this point), skip it completely when
flag_thread_jumps is not set.

try_forward_edges does not update dominance info, and merge_blocks
relies on it being up-to-date. In PR92430 stale dominance info makes
merge_blocks produce a loop in the dominator tree, which in turn makes
delete_basic_block loop forever.
Fix by freeing dominance info at the beginning of cleanup_cfg.

r266734 has introduced a new instance of jump threading pass in order to
take advantage of opportunities that combine opens up. It was perceived
back then that it was beneficial to delay it after reload, since that
might produce even more such opportunities.
Unfortunately jump threading interferes with hot/cold partitioning. In
the code from PR92007, it converts the following
+-------------------------- 2/HOT ------------------------+
| |
v v
3/HOT --> 5/HOT --> 8/HOT --> 11/COLD --> 6/HOT --EH--> 16/HOT
| ^
| |
+-------------------------------+
into the following:
+---------------------- 2/HOT ------------------+
| |
v v
3/HOT --> 8/HOT --> 11/COLD --> 6/COLD --EH--> 16/HOT
This makes hot bb 6 dominated by cold bb 11, and because of this
fixup_partitions makes bb 6 cold as well, which in turn makes EH edge
6->16 a crossing one. Not only can't we have crossing EH edges, we are
also not allowed to introduce new crossing edges after reload in
general, since it might require extra registers on some targets.
Therefore, move the jump threading pass between combine and hot/cold
partitioning. Building SPEC 2006 and SPEC 2017 with the old and the new
code indicates that:
* When doing jump threading right after reload, 3889 edges are threaded.
* When doing jump threading right after combine, 3918 edges are
threaded.
This means this change will not introduce performance regressions.

This patch replaces get_call_reg_set_usage with insn_callee_abi,
which returns the ABI of the target of a call insn. The ABI's
full_reg_clobbers corresponds to regs_invalidated_by_call,
whereas many callers instead passed call_used_or_fixed_regs, i.e.:
(regs_invalidated_by_call | fixed_reg_set)
The patch slavishly preserves the "| fixed_reg_set" for these callers;
later patches will clean this up.

CALL_USED_REGISTERS and call_used_regs infamously contain all fixed
registers (hence the need for CALL_REALLY_USED_REGISTERS etc.).
We try to recover from this to some extent with:
/* Contains 1 for registers that are set or clobbered by calls. */
/* ??? Ideally, this would be just call_used_regs plus global_regs, but
for someone's bright idea to have call_used_regs strictly include
fixed_regs. Which leaves us guessing as to the set of fixed_regs
that are actually preserved. We know for sure that those associated
with the local stack frame are safe, but scant others. */
HARD_REG_SET x_regs_invalidated_by_call;
Since global registers are added to fixed_reg_set and call_used_reg_set
too, it's always the case that:
call_used_reg_set == regs_invalidated_by_call | fixed_reg_set
This patch replaces all uses of call_used_reg_set with a new macro
call_used_or_fixed_regs to make this clearer.
This is part of a series that allows call_used_regs to be what is
now call_really_used_regs. It's a purely mechanical replacement;
later patches clean up obvious oddities like
"call_used_or_fixed_regs & ~fixed_regs".

This change is needed to avoid a regression in gcc.dg/ifcvt-3.c
for a later patch. Without it, we enter CSE with a dead comparison left
by if-conversion and then eliminate the second (live) comparison in
favour of the dead one. That's functionally correct in itself, but it
meant that we'd combine the subtraction and comparison into a SUBS
before we have a chance to fold away the subtraction.

This patch changes the MEM_OFFSET and MEM_SIZE memory attributes
from HOST_WIDE_INT to poly_int64. Most of it is mechanical,
but there is one nonbovious change in widen_memory_access.
Previously the main while loop broke with:
/* Similarly for the decl. */
else if (DECL_P (attrs.expr)
&& DECL_SIZE_UNIT (attrs.expr)
&& TREE_CODE (DECL_SIZE_UNIT (attrs.expr)) == INTEGER_CST
&& compare_tree_int (DECL_SIZE_UNIT (attrs.expr), size) >= 0
&& (! attrs.offset_known_p || attrs.offset >= 0))
break;
but it seemed wrong to optimistically assume the best case
when the offset isn't known (and thus might be negative).
As it happens, the "! attrs.offset_known_p" condition was
always false, because we'd already nullified attrs.expr in
that case:
/* If we don't know what offset we were at within the expression, then
we can't know if we've overstepped the bounds. */
if (! attrs.offset_known_p)
attrs.expr = NULL_TREE;
The patch therefore drops "! attrs.offset_known_p ||" when
converting the offset check to the may/must interface.

This patch adjusts numerous parts of the compiler that would
malfunction should they find debug markers at points where they may be
introduced. The changes purport to allow the compiler to pass
bootstrap-debug-lean (-fcompare-debug in stage3) at various
optimization levels, as well as bootstrap-debug-lib (-fcompare-debug
for target libraries), even after the compiler is changed so that
debug markers are introduced in code streams at spots where earlier
debug stmts, insns and notes wouldn't normally appear.
This patch depends on an earlier SFN boilerplate patch, and on another
SFN patch that introduces new RTL insn-walking functions.

The function bb_is_just_return finds if the BB it is asked about does
just a return and nothing else. It currently does not allow clobbers
in the block either, which we of course can allow just fine.
This patch changes that.

If we have a conditional jump that has only a return in both the branch
path and the fallthrough path, and the return on the branch path can not
be made a conditional return, we will try to make a conditional return
from the fallthrough path, and that does not work because we then try
to redirect the (new) jump in the fallthrough block to the original
dest in the branch path, which is the exit block.
For the testcase on ARM we end up in this situation because before the
jump2 pass there are some other insns in the return blocks as well, but
the same insns in both, so those are moved above the conditional jump.
Only later (in the ce3 pass) are the conditional jump and two returns
melded into one return, so we need to handle this strange case here.
PR rtl-optimization/71028
* cfgcleanup.c (try_optimize_cfg): Do not flip a conditional
jump with just a return in the fallthrough block if the branch
block contains just a returns as well.
From-SVN: r236106

This patch makes cfgcleanup optimize jumps to returns. There are three
cases this handles:
-- A jump to a return; this is simplified to just that return.
-- A conditional branch to a return; simplified to a conditional return.
-- A conditional branch that falls through to a return. This is simplified
to a conditional return (with the condition inverted), falling through
to a jump to the original destination. That jump can then be optimized
further, as usual.
This handles all cases the current function.c does, and a few it misses.
* cfgcleanup.c (bb_is_just_return): New function.
(try_optimize_cfg): Simplify jumps to return, branches to return,
and branches around return.
From-SVN: r235904

|
If the jump_block here contains just a return, we will crash later
in invert_jump. Don't allow that case.
* cfgcleanup.c (try_simplify_condjump): Don't try to simplify a
branch to a return.
