stable/11 -r307797 on BPi-M3 (cortex-a7): xgcc's cc1 during lang/gcc6 build gets SIGSYS failures (/usr/ports -r424540)
[I'll be submitting some of the below information to bugzilla.]
While trying to build lang/gcc6 on a BPI-M3 (Cortex-A7, ALLWINNER) I got
"xgcc: internal compiler error: Bad system call (program cc1)", which
means a SIGSYS (signal 12) resulted.
[I will note that I'v never seen this issue (so far) on the rpi2: This may
be KERNCONF=ALLWINNER specific. But I've not yet updated to -r307797 on the
rpi2. The BPI-M3 context is new for me; the rpi2 I've been using for a long
time.]
This was under/on:

[Note this was cross-built and then a matching svnlite co was done on the
BPi-M3. So the source timestamps on the BPi-M3 are newer than the times from the
cross build.]

(All the lang/gcc6 prerequisites built okay on the BPi-M3.)
Unfortunately direct execution of the cc1 command on the libgcc2.i from a use of
-save-temps does not fail. For some reason the failure is only when xgcc causes
the cc1 command execution.
Also unfortunately truss gets a segmentation fault of its own trying the handle
watching the SIGSYS related activity. (A truss bugzilla report has been made.)
Thus the following tail of the truss output for leading up to the SIGSYS does
not cover the SIGSYS related activity itself:

Via using gdb on truss [with truss running xgcc and xgcc in turn running its cc1
instance]:
root at
bananapi-m3:/usr/obj/portswork/usr/ports/lang/gcc6/work/.build/armv6-portbld-freebsd11.0/libgcc
# gdb truss
. . . [the below is in enter_syscall] . . .
380 t->cs.name = sysdecode_syscallname(t->proc->abi->abi,
t->cs.number);
381 if (t->cs.name == NULL)
(gdb)
382 fprintf(info->outfile, "-- UNKNOWN %s SYSCALL %d --\n",
383 t->proc->abi->type, t->cs.number);
384
385 sc = get_syscall(t->cs.name, narg);
386 t->cs.nargs = sc->nargs;
387 assert(sc->nargs <= nitems(t->cs.s_args));
388
389 t->cs.sc = sc;
(t->cs.name == NULL after line 380). . .
Looking at the two things that the fprintf on lines 382 and 383 would report:
(gdb) print t->proc->abi->type
$4 = 0x10166 "FreeBSD ELF32"
(gdb) print t->cs.number
$5 = 580828064
FYI: 580828064 = 0x229EBBA0
(sc == NULL results from line 385 so sc->nargs on line 386 gets a SIGSEGV.)
Just for completness:
(gdb) print *t
$2 = {entries = {le_next = 0x0, le_prev = 0x20617070}, proc = 0x20617060, tid =
100150, in_syscall = 1, cs = {sc = 0x0, name = 0x0, number = 580828064, args =
0x2061b0c0, nargs = 0,
s_args = 0x2061b0ec}, before = {tv_sec = 1477418265, tv_nsec = 492342263},
after = {tv_sec = 1477418265, tv_nsec = 492496630}}
(gdb) print sc
$3 = (struct syscall *) 0x0

Unfortunately direct execution of the reported cc1 command on the libgcc2.i in
question does not fail.
Attempting to run the xgcc command under truss got a segmentation fault in truss
itself:

stable/11 -r307797 on BPi-M3 (cortex-a7): xgcc's cc1 during lang/gcc6 build gets SIGSYS failures (/usr/ports -r424540)
[A top post noting that user "ast" CSW's are involved and other details in the sequence leading up to the failure.] Using "ktrace -i -t +fw" it looks like every repeat of the problem ends up with the following sort of sequence (a variation is shown later): 34629 cc1 CALL mmap(0,0x4000,0x3<PROT_READ|PROT_WRITE>,0x1002<MAP_PRIVATE|MAP_ANON>,0xffffffff,0x1c,0,0) 34629 cc1 RET mmap 568225792/0x21de7000 34629 cc1 PFLT 0x21de7000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x21de8000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x21de9000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x21dea000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x229e8000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x229e9000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x229ea000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 CSW stop user "ast" 34629 cc1 CSW resume user "ast" 34629 cc1 PFLT 0x229eb000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 PFLT 0x229ec000 VM_PROT_WRITE 34629 cc1 PRET KERN_SUCCESS 34629 cc1 CALL [-17504] 34629 cc1 RET [-17504] -1 errno 78 Function not implemented 34629 cc1 PSIG SIGSYS SIG_DFL code=SI_KERNEL 34629 cc1 NAMI "cc1.core" 34630 as CSW stop kernel "piperd" 34630 as Events dropped. 34630 as RET read 0 34630 as CALL close(0) 34630 as RET close 0 . . . I'll note that for the source this was compiling I used gdb truss with run -feH -o truss.log and it reported: (gdb) print t->cs.number $5 = 580828064 FYI: 580828064 = 0x229EBBA0 where the truss segmentation fault was at line 385 of the following (sc==NULL in the context):> 380 t->cs.name = sysdecode_syscallname(t->proc->abi->abi, t->cs.number); > 381 if (t->cs.name == NULL) > (gdb) > 382 fprintf(info->outfile, "-- UNKNOWN %s SYSCALL %d --\n", > 383 t->proc->abi->type, t->cs.number); > 384 > 385 sc = get_syscall(t->cs.name, narg); > 386 t->cs.nargs = sc->nargs; > 387 assert(sc->nargs <= nitems(t->cs.s_args)); > 388 > 389 t->cs.sc = sc;The 229E matched the upper part of local PFLT activity around the user "ast" CSW's, including just before the bad call. But the details do vary some based on the source file being compiled. For example here the user "ast" CSW's are just before the mmap but are still just after the 0x229ea000 PFLT: 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0xbfbf2000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x229e7000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x229e8000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x229e9000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x229ea000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 CSW stop user "ast" 34698 cc1 CSW resume user "ast" 34698 cc1 CALL mmap(0,0x4000,0x3<PROT_READ|PROT_WRITE>,0x1002<MAP_PRIVATE|MAP_ANON>,0xffffffff,0,0,0) 34698 cc1 RET mmap 568225792/0x21de7000 34698 cc1 PFLT 0x21de7000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x21de8000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x21de9000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x21dea000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 PFLT 0x229eb000 VM_PROT_WRITE 34698 cc1 PRET KERN_SUCCESS 34698 cc1 CALL [-25840] 34698 cc1 RET [-25840] -1 errno 78 Function not implemented 34698 cc1 PSIG SIGSYS SIG_DFL code=SI_KERNEL 34698 cc1 NAMI "cc1.core" 34699 as CSW stop kernel "piperd" 34699 as Events dropped. 34699 as RET read 0 34699 as CALL close(0) 34699 as RET close 0 -25840 in 2's complement is: 0xF...F9B10 Here doing the gdb truss instead reports: (gdb) print t->cs.number $1 = 580819728 and 580819728 = 0x229E9B10 and the 229E part matches several PFLT's in the area, including just before the bad call as well as just before the user "ast"s. Between them are some PFLT's that do not match. I would guess that the 229E in t->cs.number in truss is from the PFLT just before the failing syscall in each case. ==Mark Millard markmi at dsl-only.net On 2016-Oct-25, at 2:32 PM, Mark Millard <markmi at dsl-only.net> wrote:> [I'll be submitting some of the below information to bugzilla.] > > While trying to build lang/gcc6 on a BPI-M3 (Cortex-A7, ALLWINNER) I got "xgcc: internal compiler error: Bad system call (program cc1)", which means a SIGSYS (signal 12) resulted. > > [I will note that I'v never seen this issue (so far) on the rpi2: This may be KERNCONF=ALLWINNER specific.
