Re: Reload problems with only one base reg for base + offset addressing mode

RE: SH optimized software floating point routines
On Thu, 22 Jul 2010, Joern Rennecke wrote: Quoting Joseph S. Myers jos...@codesourcery.com: That diff does not appear to relate to undefined behavior. GCC considers these out-of-range conversions to yield an unspecified value, possibly raising an exception, as per Annex F, and does not take the liberty of optimizing on the basis of them being undefined when not in an IEEE mode. Well, still, the test is wrong in possibly raising an exception there, with no provisions to ignore the exception or catch any signal raised. The expectation is that floating-point exceptions will not trap by default, again in accordance with Annex F even when not in an IEEE mode. -- Joseph S. Myers jos...@codesourcery.com
Re: SH optimized software floating point routines
Joern Rennecke wrote: Quoting Christian Bruel christian.br...@st.com: Using the ieee-sf.S + this patch OK Is this only a proof-of-concept, because you only change the ne[sd]f2 implementation? I changed also the unordered comparison patterns. (cmpunsf_i1, cmpundf_i1). But yes, the other functions that would need the same kind of check would be unordsf2, and all the comparisons (gtsf2, gesf2f...) for floats and doubles. But I will only consider those after/if we all agree that this needs to be done instead of keeping the current QNaN only restrictions. And you go out of your way to only accept a restricted set of values. This hold for the original optimized implementation as well, for example I don't think that 0x7f81 was caught. In fact implementing correctly the isnan check without restricted set of value makes the original discussion pointless, since the Q/S bits are a subpart of all possible codings, with any fractional part != 0. Plus, the overuse of the arithmetic unit hurts SH4-100 / SH4-200 instruction pairing. AFAICT you need only one cycle penalty, in the check_nan path: GLOBAL(nesf2): /* If the raw values are unequal, the result is unequal, unless both values are +-zero. If the raw values are equal, the result is equal, unless the values are NaN. */ cmp/eq r4,r5 mov.l LOCAL(inf2),r1 bt/s LOCAL(check_nan) mov r4,r0 or r5,r0 rts add r0,r0 LOCAL(check_nan): add r0,r0 cmp/hi r1,r0 rts movtr0 .balign 4 LOCAL(inf2): .long 0xff00 You could even save four bytes by putting the check_nan label into the delay slot, but I'm not sure if that'll discomfit any branch prediction mechanism. Thanks a lot of this one, It should fix the original problem on the restricted set of values as well. The cmpund patterns fix should probably have a similar checks. Disclaimer: I've not tested this code. For the DFmode case, what about NaNs denoted by the low word, e.g. 0x7ff0 1 ? If so, the DFmode code could become something like this: GLOBAL(nedf2): cmp/eq DBL0L,DBL1L mov.l LOCAL(inf2),r1 bf LOCAL(ne) cmp/eq DBL0H,DBL1H bt/sLOCAL(check_nan) mov DBL0H,r0 or DBL1H,r0 add r0,r0 rts or DBL0L,r0 LOCAL(check_nan): tst DBL0L,DBL0L add r0,r0 subcr1,r0 mov #-1,r0 rts negcr0,r0 LOCAL(ne): rts mov #1,r0 .balign 4 LOCAL(inf2): .long 0xffe0 For an actual patch, you need to use the SL* macros from config/sh/lib1funcs.h because the SH1 does not have delayed branches. OK, thanks

Argh, I've missed the required patterns are incorporated already
in your patch. I'll test it again with sh-softfp-predicate-fix
when the tests for 4.5.1-rc are done. Thanks!
I've tested sh-softfp-20100718-2131 + sh-softfp-predicate-fix
on -m1, -m2, -m3, -m3 -ml, -m2a on sh-elf, sh4-linux and
sh64-linux. sh64-linux required the first hunk of the attached
patch to build. The test with -m3 -ml shows some regressions
which look to be solved with the second hunk of the patch.
Now all test results look clean.
For NaN issue, I'd like to wait a full patch from Christian.
I'm curious again about the numbers with/without it.

embedded dataflow tracking code?
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi. I'm sorry if I chose wrong place for my question. I would like to load debugger, attach to working process, and at some breakpoint, instead of numerical values in the CPU registers, I would like to see genesis of each value like result of f(arg1, arg2,arg3) called at point X or result of comparison of values X and Y and so on. Probably, compiler backend could embed some dataflow tracking code between basic blocks and store information about all variables flow in some separate data segment..

Use GMP from the 4.2.x series and MPFR from the 2.3.x series. Or do not build these libraries in-tree. Yes, and verify that GMP and MPFR are correctly compiled with make check. Recent versions are miscompiled on SPARC/Solaris by GCC 4.3.x for x 3 or 4.

[Bug c/44853] can't find a register in class 'GENERAL_REGS' while reloading 'asm'
--- Comment #3 from swapnil dot tiwari1979 at gmail dot com 2010-07-23 06:33 --- this problem is not occuring with gcc-4.2 using any arm toolchain but this occurs with the latest gcc version 4.4.1 why is so. (In reply to comment #1) Can you reproduce this with GCC built using sources from http://gcc.gnu.org ? If not please report such issues to the vendors of your toolchain. If you can reproduce this with GCC built from FSF sources please let us know. Also give a better testcase which is consistent, complete and small, this is code with undefined behaviour, at the very best this is the Compiler ICE'ing on invalid code.

This isn't a mere debug info quality regression, a movl $2, (%esp) is now
optimized away, eventhough it is needed by asm volatile following it.
Here is a testcase that at -O1 -m32 now fails at runtime, while it worked well
before:
/* PR debug/36728 */
/* { dg-do run } */
/* { dg-options -O1 } */
int __attribute__((noinline))
foo (int arg1, int arg2, int arg3, int arg4, int arg5, int arg6, int arg7)
{
char x[30];
int __attribute__ ((aligned(32))) y;
y = 2;
asm volatile (cmpl $2, %0; je 1f; hlt; 1: : =m (y) : m (y));
x[0] = 25;
asm volatile ( : =m (x[0]) : m (x[0]));
return y;
}

{
int l = 0;
asm volatile ( : =r (l) : 0 (l));
foo (l + 1, l + 2, l + 3, l + 4, l + 5, l + 6, l + 30);
return 0;
}

[Bug middle-end/44690] -fzero-initialized-in-bss does not work
--- Comment #3 from jan dot kratochvil at redhat dot com 2010-07-23 11:11

(In reply to comment #1)
const int i; -fno-zero-initialized-in-bss - .bss= FAIL
You need -fno-common also to get it out of the BSS.
-fno-common now at least correctly reports:
echo 'const int i;'|gcc -fno-common -c -o k.o -x c -;echo 'const int
i;main(){}'|gcc -fno-common -c -o l.o -x c -;gcc -fno-common -o k k.o l.o
l.o:(.bss+0x0): multiple definition of `i'
k.o:(.bss+0x0): first defined here
So it is no longer SHN_COMMON, thanks.
But reopening the Bug as it is still in .bss, not in .rodata.
echo 'const int i;int main(){return *(int *)i = 0;}'|gcc -fno-common -Wall -o
1 -x c -;./1;echo $?
0
[25] .bss NOBITS 00600818 0814
0018 WA 0 0 8
Num:Value Size TypeBind Vis Ndx Name
55: 00600828 4 OBJECT GLOBAL DEFAULT 25 i
It should SEGV but it does not.
-f{,no-}zero-initialized-in-bss has no effect on it.

[Bug tree-optimization/43784] [4.6 Regression] -Os -fkeep-inline-functions causes FAIL: gcc.c-torture/execute/builtins/pr22237.c execution
--- Comment #5 from rguenth at gcc dot gnu dot org 2010-07-23 11:20 ---
Confirmed. But I think this might trigger undefined behavior according to
the C standard as you are doing
v.e.b = v.d.b;
which has overlapping lhs/rhs. And we end up with
rp:
.LFB0:
.cfi_startproc
movq%rdi, %rax
movl$v, %esi
movl$64, %ecx
rep movsl
ret
.cfi_endproc
compared to 4.5 we end up with return slot optimization for the call to rp().
Testcase that also reproduces with -O[123]:
struct s {
unsigned char a[256];
};
union u {
struct { struct s b; int c; } d;
struct { int c; struct s b; } e;
};
static union u v;
static struct s *p = v.d.b;
static struct s *q = v.e.b;
static struct s __attribute__((noinline)) rp(void)
{
return *p;
}
static void qp(void)
{
*q = rp();
}
int main()
{
int i;
for (i = 0; i 256; i++)
p-a[i] = i;
qp();
for (i = 0; i 256; i++)
if (q-a[i] != i)
__builtin_abort();
return 0;
}

(b) C binding names, i.e. subroutine foo() bind(C, name=bar) ... entry foo2() bind(C, name=bar2) ... end interface subroutine Hello() bind(C,name=bar2) end end interface call Hello() ! this should use the same backend decl as ENTRY foo2.

[Bug driver/45041] New: 'gcc -E -o -' creates ./-.exe on cygwin
For a while, the autoconf testsuite failed on cygwin, because asking gcc to run the preprocessor with an explicit output of '-' for stdout instead created a text file ./-.exe containing the preprocessor output [1]. While the autoconf workaround was simple (remove '-o -' since -E already implies a default of stdout), this anomaly in cygwin should be fixed [2].

Confirmed. We end up vectorizing
void
foo (int *a, int n)
{
int *lasta = a + n;
for (; a != lasta; a++)
{
*a *= 2;
a[1] = a[-1] + a[-2];
}
}
not seeing the dependence of *a vs a[-1] because via
initialize_data_dependence_relation we ask the alias-oracle whether
*a may alias a[-1] (which it doesn't). So we end up not computing
a dependence distance.
May we not use the alias-oracle (on the full ref) here?
