My impression is that escaping with backslashes is non-standard behavior, so we should require a parameter to invoke it. It could also be tied in with -std=legacy.

[Bug fortran/30285] New: gfortran huge (excessive?) memory usage with large modules
Hi, gfortran seems to use much more memory at compile time when I "use" larger modules that contain many symbols, even if I "use, only" selected one. In the described situation it needs significantly more memory than "competitors". The attached archive contains the following main program and three (3) large modules to demonstrate this. The variant with the commented lines uncommented goes beyond 500 MB virtual memory in a Linux/x86 machine. program main use mo_psas, only: setup_psas use mo_3dvar, only: obs, bg ! use mo_t_enkf,only: enkf_driver !

Configure with --disable-checking to disable checks. The modules are extracted from a larger project and should be sufficient to just compile the example. The project uses MPI (mpich) which is why these symbols occur quite frequently in the module files. Gfortran seems to handle the present case quite inefficiently. Maybe there is a solution that handles used modules more economically...

[Bug target/28764] [4.2 Regression] libjava build failure on sh4
--- Comment #18 from ubizjak at gmail dot com 2006-12-23 21:24 ---
(In reply to comment #12)
> As far as I can see, the i387 mode switching is already completely broken,
> because it treats the different modes of a single mode-switchable entity
> as separate entities.
NO, it is _NOT_ broken by any stretch of imagination!
Perhaps something could be writtenn in a more fancy way, but there is a reason,
why we have separate entities for x87. Please note, that at mode switch point,
we insert code that calculates mode word and stores the result in memory. This
value is then used at the point, where mode is briefly switched for the insn to
operate in desired mode.
So, consider this testcase:
--cut here--
double test(double *a, int x)
{
int i;
double z = 0.0;
for (i = 0; i < x; i++)
z += floor(a[i]) + ceil(a[i]);
return z;
}
--cut here--
This gets compiled by current approach (-O2 -ffast-math) into:
fnstcw -6(%ebp)
xorl%edx, %edx
fldz
movzwl -6(%ebp), %eax
movb$4, %ah
movw%ax, -10(%ebp)
movzwl -6(%ebp), %eax
movb$8, %ah
movw%ax, -8(%ebp)
.p2align 4,,7
.L5:
fldl(%ebx,%edx,8)
addl$1, %edx
fld %st(0)
cmpl%ecx, %edx
fldcw -8(%ebp)
frndint
fldcw -6(%ebp)
fxch%st(1)
fldcw -10(%ebp)
frndint
fldcw -6(%ebp)
faddp %st, %st(1)
faddp %st, %st(1)
jne .L5
Note that mode word calculation is pushed out of the loop.
I actualy considered an idea that implemented proposed
"several-modes-for-one-entity" approach for x87. However, modes are switched
_inside_ the loop, so by this approach mode calculation code also stays inside:
.L5:
fldl(%ebx,%edx,8)
addl$1, %edx
fnstcw -6(%ebp)
fld %st(0)
cmpl%ecx, %edx
movzwl -6(%ebp), %eax
movb$8, %ah
movw%ax, -8(%ebp)
movzwl -6(%ebp), %eax
fldcw -8(%ebp)
frndint
fldcw -6(%ebp)
fxch%st(1)
movb$4, %ah
movw%ax, -10(%ebp)
fldcw -10(%ebp)
frndint
fldcw -6(%ebp)
faddp %st, %st(1)
faddp %st, %st(1)
jne .L5
Now, which code is preferred?

Is that also aliasing or shall be analyzed? It's possible it was my aliasing fix, but it's hard to say. I had only seen cases where it increased mem usage ~3-5% (this was on large testcases too). It certainly shouldn't run out of memory. In any case, i'm working on testing bitmaps for may-aliases right now. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30089

--- Comment #3 from steven at gcc dot gnu dot org 2006-12-23 12:52 ---
This not-for-including patch shows that we should match "\\" in io.c and treat
it as a single '\\' character. This is what g77 appears to do, too.

My understanding of io.c is not quite good, so perhaps someone who understands
that code well can have a look at a proper fix.

[Bug target/30282] Optimization flag -O1 -fschedule-insns2 cause red zone to be used when there is none
--- Comment #1 from pinskia at gcc dot gnu dot org 2006-12-23 10:31 ---
For 4.0 and above your sample code works but that is a different issue.
Here is a testcase which fails for 4.0 and above:
int find_num(int i)
{
int arr[5] = {0, 1, 2, 3, 4};
return arr[i];
}
The problem is the scheduler is moving the load past the update of r1 which is
invalid for the SYSV ABI to do as there is no red zone.
This has almost always been an issue since the rs6000 target was added and/or
the scheduler was added.

[Bug c/30282] New: Optimization flag -O2 generate error stack operating code
Stack operating code that generated by gcc have an error. In some operating
system that saved the thread's context in stack when schedule, it will be have
critical problem.
Enabling the compiler optimalisation (-O2 option) the error will be occuring,
and don't occur when using option -O1 or -O0.
--- sample ---
array.c:
int find_num(int i)
{
const int arr[5] = {0, 1, 2, 3, 4};
return arr[i];
}
using command:
ppc-eabi-gcc -c -O2 array.c -o array.o
ppc-eabi-objdump -S array.o
the disassemble code is:
:
0: 3d 60 00 00 lis r11,0
4: 94 21 ff d0 stwur1,-48(r1)
8: 39 2b 00 00 addir9,r11,0

18: 80 09 00 04 lwz r0,4(r9)
1c: 81 69 00 08 lwz r11,8(r9)

40: 80 69 00 10 lwz r3,16(r9)
44: 4e 80 00 20 blr
The instruction 3c let stack pointer back, and instruction 40 load data from
the stack, this is error. The true code must be:
lwz r3,16(r9)
addir1,r1,48
And when you using option -O1, the code generated is true.
