[Bug testsuite/42313] FAIL: gcc.target/i386/builtin-unreachable.c scan-assembler-not %e[bs]p on i686 darwin
--- Comment #5 from daney at gcc dot gnu dot org 2009-12-08 17:34 --- (In reply to comment #4) Mike Stump says that the frame can be optimized away on darwin. However, Apple's 4.2.1 compiler in darwin10 also appears to leave the stack frame... That compiler doesn't implement __builtin_unreachable(), so is irrelevant to the discussion of this bug. Of interest is why, in a leaf function that doesn't use the stack, the stack pointer is adjusted. A darwin hacker will probably have to look into it as I only have access to GNU/Linux targets. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42313
[Bug testsuite/42313] FAIL: gcc.target/i386/builtin-unreachable.c scan-assembler-not %e[bs]p on i686 darwin
--- Comment #3 from daney at gcc dot gnu dot org 2009-12-07 17:27 ---
It is failing because the redundant stack pointer adjustments are not being
removed.
This test is passing for me on i686-pc-linux-gnu at r154987, so I think it
must be darwin specific.
If for some reason darwin requires a stack frame, perhaps the:
/* { dg-final { scan-assembler-not %e\[bs\]p } } */
part could be made conditional on darwin.

Register $3 (v1) returns with uninitialized garbage. This is the high part of
the 64 bit return value.
I am not sure what should happen here. Really the d asm constraint should
not match a 64 bit variable for the o32 ABI.

[Bug target/39079] New: MIPS: __builtin___clear_cache() broken on SMP ISA_HAS_SYNCI systems.
We expand __builtin___clear_cache() to a 'synci' instruction on ISA_HAS_SYNCI systems, which invalidates the icache only on the local CPU. On an SMP system, the caches on all CPUs should be invalidated. To achieve this we need to drop back to the old way of doing things by using the cache flush system call. -- Summary: MIPS: __builtin___clear_cache() broken on SMP ISA_HAS_SYNCI systems.

[Bug libgcj/18266] GCJ: Using references drops finalizers causing all apps to eventually crash ( SIGSEGV in GC_register_finalizer_inner () )
--- Comment #20 from daney at gcc dot gnu dot org 2008-09-26 15:58 --- 1) Create an object. 2) Enter a synchronized block on the object and do Object.wait(). 3) In a second thread, enter a synchronized block on the object. There is lock contention, heavy lock escalation is guaranteed. Hash synchronization code registers a finalizer recording the old finalizer. The old finalizer is null as no finzlizers have been registered for the object. 4) Create a WeakReference to the Object. This adds a finalizer, overwriting and thus losing the Hash synchronization's finalizer. 5) Both threads leave the synchronized block. At this point the heavy_lock object in the hash synchronization code in no longer in use and is eligible for clean up. 6) Many other locks are acquired and released, some of these hash to the same value as the lock used in steps 1 and 2. Eventually the hash row for these locks is cleaned up. The clean up code restores the saved finalizer from step 3 which was null, thus overwriting the WeakReference's finalizer. 7) WeakReference's referent is GCed, but its finalizer has been removed in step 6, so it does not get cleaned up. If you ever synchronize o the If the object itself is a WeakReference, the same thing happens, but ref-enqueue is called on the WeakReference. If A different type of object has been allocated in the WeakReference's previous location, when the referent is finalized ref-enqueue will be called through the vtable of the new object resulting sometimes in SIGSEGV or other types of bad behavior. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18266

It is reproducible in a cross compiler as well.
This is my command line:

Changing to -march={mips32,mips32r2,r5000} fixes the problem. It seems to be
sb1 specific.

Can this be reproduced natively on MIPS with 139918? The ICE first appears in 139854 (the sel-sched merge) it is still present in 139940 (and about 10 other version I tested between the two including 139918).

--- Comment #1 from daney at gcc dot gnu dot org 2007-11-11 06:29 --- The problem is that $gp is clobbered at the nonlocal_goto_receiver but it is not being restored. Currently the nonlocal_goto_receiver has a condition of TARGET_CALL_CLOBBERED_GP, but this is not correct. I think it should be unconditional. In: http://gcc.gnu.org/viewcvs?view=revrevision=125941 I renamed this from exception_receiver. I wonder if the exception_receiver really should be conditional on TARGET_CALL_CLOBBERED_GP in which case there should be both an exception_receiver and nonlocal_goto_receiver. It would seem so as the unwinder should restore $gp making it redundant in the exception_receiver. Hmm. This is really the same as bug 32406 I will mark it as a duplicate and reopen 32406 *** This bug has been marked as a duplicate of 32406 *** -- daney at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |RESOLVED Resolution||DUPLICATE http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34062
[Bug target/32406] [4.3 Regression] MIPS: FAIL in nestfunc-6.c at -O3
--- Comment #6 from daney at gcc dot gnu dot org 2007-11-11 06:32 --- Well the fix only works for o32. As noted in PR 34062, n32 is broken. I would guess n64 as well. I will take another try at fixing it. Perhaps the second attempt will work out a little better than the first. -- daney at gcc dot gnu dot org changed: What|Removed |Added Status|RESOLVED|UNCONFIRMED Resolution|FIXED | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32406

--- Comment #7 from daney at gcc dot gnu dot org 2007-11-11 07:05 --- Created an attachment (id=14528) -- (http://gcc.gnu.org/bugzilla/attachment.cgi?id=14528action=view) Proposed patch second half. Completely untested patch. It will probably take me a couple of weeks to test it fully. I will start testing on mipsel-linux... Q: Is the first exception_receiver define_expand redundant (with TARGET_CALL_CLOBBERED_GP)? Does it just defer to the nonlocal_goto_receiver? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32406

Also last night (with an current but unremembered SVN version) I was able to build mips64-linux-gnu with the default debian-etch gcc (4.1) on my O2. None of these are exactly what you are doing, but somewhat similar. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34007

--- Comment #6 from daney at gcc dot gnu dot org 2007-11-05 17:34 --- As of r129803, I can bootstrap c,c++,java on my mipsel-linux build machine with 128MB RAM again. Although some files require more than 128MB of virtual memory, I have plenty of swap and the system does not thrash so horribly that it cannot complete a bootstrap. Unless there are protests, I will mark the bug as FIXED in a couple of days. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32653
