sh64-elf build failure because of lib1funcs-Os-4-200.asm
Hi Joern, Hi Alex, The sh64-elf toolchain currently fails to build from the mainline GCC sources because it contains unsupported SH assembler: ./xgcc \ -B./ \ -B/usr/local/sh64-superh-elf/bin/ \ -isystem /usr/local/sh64-superh-elf/include \ -isystem /usr/local/sh64-superh-elf/sys-include \ -L.../sh64-superh-elf/ld \ -c \ -o sdivsi3_i4i-Os-4-200.o \ -DL_sdivsi3_i4i \ -x assembler-with-cpp .../gcc/config/sh/lib1funcs-Os-4-200.asm .../gcc/config/sh/lib1funcs-Os-4-200.asm: Assembler messages: .../gcc/config/sh/lib1funcs-Os-4-200.asm:277: Error: unknown opcode .../gcc/config/sh/lib1funcs-Os-4-200.asm:278: Error: unknown opcode [snip] I am not sure how this should be fixed however. Should the functions in lib1funcs-02-4-200.asm be protected by another #ifdef so that they are not built for this target ? Or maybe the rules in t-sh need to be updated to include an architecture selection switch ? (eg -m2a-single ?) Cheers Nick

The following testcase produces an ICE in subst_reloads, when compiled
with -march=z990 -O2 -ftracer:
snip

extern int printf (__const char *__restrict __format, ...);

{

char msglen[4];

} TESTSTRUCT;

printf(a);
if (memcmp(testtb-msgtype, a, 2))
printf(a);
printf(b);
}

Assembling functions:
test_func
test.i: In function #8216;test_func#8217;:
test.i:19: internal compiler error: in subst_reloads, at reload.c:6108
This already ICEs with the hammer branch, and I think is also still a latent
problem in trunk. It's a combination of the tracer and CSE working hand in
hand to produce an invalid MEM address. It goes like so:
1) Initially the memcmp() call is implemented by the cmpmem_short instruction
of s390. Remember that with -march=z990 we have long displacements active.
The instruction emitted for the memcmp() is:
(insn 69 68 70 1 (parallel [
(set (reg:CCU 33 %cc)
(compare:CCU (mem/s:BLK (reg/f:DI 46) [0 S2 A8])
(mem/s:BLK (plus:DI (reg/v/f:DI 43 [ testtb ])
(const_int 4096 [0x1000]))
[0 variable.msgtype+0 S2 A8])))
(use (const_int 1 [0x1]))
(use (const:BLK (unspec:BLK [
(const_int 0 [0x0])
] 213)))
(clobber (scratch:DI))
]) 92 {*cmpmem_short} (nil)
(expr_list:REG_EQUAL (compare:CCU (mem/s:BLK (symbol_ref/f:DI (*.LC0)
[flags 0x2] string_cst 0x2368b70) [0 S2 A8])
(mem/s:BLK (plus:DI (reg/v/f:DI 43 [ testtb ])
(const_int 4096 [0x1000]))
[0 variable.msgtype+0 S2 A8]))
(nil)))
So, everything fine, but note the (mem (plus (reg 43) (4096)) operand, which
we are going to screw up soon.
2) Then -ftracer comes along an duplicates a trace through the whole function
using the if (testtb) predicate. So we end up with two copies of the
body, including the above instruction. One of them under the testtb==0
branch.
3) Now CSE2 comes into play, with it's path following feature. In the second
version of the above insn it knows that testtb (== pseudo 43) is zero.
Hence it happily changes the insn to read:
(insn 24 23 25 3 (parallel [
(set (reg:CCU 33 %cc)
(compare:CCU (mem/s:BLK (reg/f:DI 46) [0 S2 A8])
(mem/s:BLK (const_int 4096 [0x1000])
[0 variable.msgtype+0 S2 A8])))
(use (const_int 1 [0x1]))
(use (const:BLK (unspec:BLK [
(const_int 0 [0x0])
] 213)))
(clobber (scratch:DI))
]) 92 {*cmpmem_short} (nil)
Note how the operand in question now is (mem (const_int 4096)). That is
fine so far normally, as the compiler can't know that this is going to
be in invalid address operand. It can't know that because all predicates
say that it is valid.
4) reload comes over that insn, looks at the various operands and addresses
and also determines that (mem (const_int 4096)) is valid because
strict_memory_address_p returns true for it.
5) But then the constraints are checked too. And we use 'Q' constraints
in the cmpmem_short insn:
(define_insn *cmpmem_short
[(set (reg:CCU CC_REGNUM)
(compare:CCU (match_operand:BLK 0 memory_operand Q,Q,Q)
(match_operand:BLK 1 memory_operand Q,Q,Q)))
(use (match_operand 2 nonmemory_operand n,a,a))
(use (match_operand 3 immediate_operand X,R,X))
(clobber (match_scratch 4 =X,X,a))]
...
And the 'Q' constraint forbids long displacements also on long disp
machines. So we now have an inconsistent situation. As the constraints
don't match we try to reload this address operand (const_int 4096):
Reloads for insn # 24
Reload 0: reload_in (VOID) = (const_int 4096 [0x1000])
ADDR_REGS, RELOAD_FOR_INPUT (opnum = 1)
reload_in_reg: (const_int 4096 [0x1000])
But this operand can't be reloaded easily, because the const_int has no
mode, hence this whole reload has only VOIDmode, and no register can
be found for it. Actually this situation should never happen (i.e. a
modeless reload), that's why it isn't handled in push_reload and friends.
All these invalid addresses should have been created a reload for much
earlier than in the constraint checking.
I unfortunately don't have a good idea how to fix this. I think these
large displacements much somehow be forbidden already in the predicate,
not only via the constraints, which would mean that one can't
[Bug target/27619] wrong code for mixed-mode division with -mpowerpc64 -O1
--- Comment #12 from dje at gcc dot gnu dot org 2006-05-18 15:56 ---
Users are suppose to control the architecture and code generation through
-mcpu=XXX, which sets the architecture options in self-consistent ways for the
target. On Darwin, -mcpu=G5 sets -mpowerpc64; on Linux, -mpowerpc64
specifically is disabled for -mcpu=G5. 64-bit Darwin kernel always performs
64-bit context switch and apparently 64-bit Linux kernel does not.
This all is controlled by the OS_MISSING_POWERPC64 macro. The macro is defined
for AIX and Linux and PPC64 Linux tests TARGET_64BIT on PPC64 Linux, i.e., it
only works for -m64 on PPC64 Linux.
If you want to add an error, follow the example from SUBTARGET_OVERRIDE_OPTIONS
in aix52.h:
if (TARGET_POWERPC64 ! TARGET_64BIT) \
{ \
error (-maix64 required: 64-bit computation with 32-bit addressing not
yet supported); \
}

--- Comment #2 from krebbel at gcc dot gnu dot org 2006-05-18 16:59 --- Thanks for your comprehensive debugging! At first glance I would say reload should take a word_mode register and reload the constant. The code added by your patch to legitimate_address_p says that a single number is not a valid address which isn't true. We also allow reg+reg+constant in legitimate_address_p and rely on reload to fix this for Q and S constraints and I think the same should happen here as well. -- krebbel at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2006-05-18 16:59:37 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27661

[Bug debug/27672] New: C frontend does not generate line information for multi-line conditions
Compile something like this with debugging information: if (func1 () || func2 () || func3 ()) Set a breakpoint on func1, and then use GDB's finish command to leave the function. You'll be back on the first line of the if. Same if you finish from func2. Nothing in the process of parsing a conditional expression sets expression locations for individual parts of the expression. We do set a line number on the outer compound expression, and that points at the beginning. It would be strange to single-step onto the conditional jump instruction and be taken back to the top of the if. So this may not be a straightforward fix. -- Summary: C frontend does not generate line information for multi- line conditions Product: gcc Version: 4.1.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: debug AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: drow at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27672

[Bug c/27673] [4.2 Regression] Gcc failed to bootstrap on Linux
--- Comment #9 from pinskia at gcc dot gnu dot org 2006-05-19 01:40 --- (In reply to comment #7) I'm building a cross compiler now... Just try the testcases on a native compiler, there should be no difference. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27673
[Bug c/27673] [4.2 Regression] Gcc failed to bootstrap on Linux
--- Comment #10 from mrs at apple dot com 2006-05-19 02:11 --- A stage1 cross compiler with --enable-checking=assert targeting --target=i686-unknown-linux-gnu hosted on darwin doesn't seem to fail, nor does a darwin native compiler with --enable-checking=assert. I've reviewed the code, and it all looks very safe wrt the data structures. I'm expected an uninitialized scope data structure, but I see they carefully zero it and manage it cleared. Anybody have any hints, I'll see if I can dig out a linux box to try next. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27673
