The plan is to stop this from happening. I'm working on it.

With current CVS head I no longer see the spurious build failures.

Hi,
I've been having some trouble building gcc 4.0.1 for mips target on a
mingw host
The build fails at this point

I've attached the saved temp files.
The same build process works fine on linux and I've compared output. The
preprocessed source is identical barring paths. The assembly output
differs only in the function prologue
on mingw built compiler
__muldi3:
.frame $sp,0,(null) # vars= 7640055, regs= 0/0, args= 0, gp= 0
on linux built compiler
__muldi3:
.frame $sp,0,$31 # vars= 0, regs= 0/0, args= 0, gp= 0
can anyone point me in the right direction? I'm not quite sure what I
should be looking for.
Dave

No you aren't. You're using a modified version of the gcc-4.0.1 sources
and you're targetting PSP. That may be a MIPS backend, but it's a different
_target_.

There's no such thing in FSF gcc (unless it was sneaked in just after
RC2...):

^^^^^^ ^^^^^^
This is very bad. This is even worse.
Stack frame generation / layout is going wrong if it thinks __muldi3 needs
seven and a bit megs of stack. However, perhaps that's not the correct
number for how much it actually does think it wants.

You're looking for gcc to be calling *printf and passing a NULL argument
to a %s format character, basically. Whatever patches you have applied must
be faulty. The bad call is in gcc/config/mips/mips.c
(mips_output_function_prologue):
if (!flag_inhibit_size_directive)
{
/* .frame FRAMEREG, FRAMESIZE, RETREG */
fprintf (file,
"\t.frame\t%s," HOST_WIDE_INT_PRINT_DEC ",%s\t\t"
"# vars= " HOST_WIDE_INT_PRINT_DEC ", regs= %d/%d"
", args= " HOST_WIDE_INT_PRINT_DEC
", gp= " HOST_WIDE_INT_PRINT_DEC "\n",
(reg_names[(frame_pointer_needed)
? HARD_FRAME_POINTER_REGNUM :
STACK_POINTER_REGNUM]),
((frame_pointer_needed && TARGET_MIPS16)
? tsize - cfun->machine->frame.args_size
: tsize),
reg_names[GP_REG_FIRST + 31],
cfun->machine->frame.var_size,
cfun->machine->frame.num_gp,
cfun->machine->frame.num_fp,
cfun->machine->frame.args_size,
cfun->machine->frame.cprestore_size);
Hmm. Perhaps we have HOST_WIDE_INT problems for mingw host here? If
cfun->machine->frame.var_size was a long long, and HOST_WIDE_INT_PRINT_DEC
for mingw is just "%d" or "%ld" rather than "%lld", that would push an extra
NULL word onto the stack that would be taken as the parameter for %s because
the "%d" wouldn't be advancing the varargs pointer past the whole of the
second format arg...

Ooops, slight braino there. I meant the second argument involving
cfun->machine->frame.args_size may be pushing reg_names[GP_REG_FIRST + 31]
along. You could verify that was happening by running cc1 under gdb,
setting a breakpoint here, and checking that reg_names[GP_REG_FIRST + 31]
isn't actually NULL. You may also be able to workaround the bug with
-finhibit-size-directive.
cheers,
DaveK

:) fair enough, the patches are currently minimal for gcc though.

And that's exactly the problem.
in /gcc/config/i386/xm-mingw32.h we have
/* MSVCRT does not support the "ll" format specifier for printing
"long long" values. Instead, we use "I64". */
#define HOST_LONG_LONG_FORMAT "I64"
then in gcc/hwint.h we have
/* The string that should be inserted into a printf style format to
indicate a "long long" operand. */
#ifndef HOST_LONG_LONG_FORMAT
#define HOST_LONG_LONG_FORMAT "ll"
#endif
and later in the same file
#if HOST_BITS_PER_WIDE_INT == HOST_BITS_PER_LONG
# define HOST_WIDE_INT_PRINT "l"
# define HOST_WIDE_INT_PRINT_C "L"
/* 'long' might be 32 or 64 bits, and the number of leading zeroes
must be tweaked accordingly. */
# if HOST_BITS_PER_WIDE_INT == 64
# define HOST_WIDE_INT_PRINT_DOUBLE_HEX "0x%lx%016lx"
# else
# define HOST_WIDE_INT_PRINT_DOUBLE_HEX "0x%lx%08lx"
# endif
#else
# define HOST_WIDE_INT_PRINT "ll"
# define HOST_WIDE_INT_PRINT_C "LL"
/* We can assume that 'long long' is at least 64 bits. */
# define HOST_WIDE_INT_PRINT_DOUBLE_HEX \
"0x%" HOST_LONG_LONG_FORMAT "x%016" HOST_LONG_LONG_FORMAT "x"
#endif /* HOST_BITS_PER_WIDE_INT == HOST_BITS_PER_LONG */
so the HOST_WIDE_INT_PRINT ignores the mingw override.
I've currently patched as follows
diff -Naurb gcc-4.0.1/gcc/hwint.h gcc-4.0.1-new/gcc/hwint.h
--- gcc-4.0.1/gcc/hwint.h Wed Nov 24 04:31:57 2004
+++ gcc-4.0.1-new/gcc/hwint.h Thu Jul 21 14:37:06 2005
@@ -80,7 +80,7 @@
# define HOST_WIDE_INT_PRINT_DOUBLE_HEX "0x%lx%08lx"
# endif
#else

# define HOST_WIDE_INT_PRINT_C "LL"

# define HOST_WIDE_INT_PRINT_DOUBLE_HEX \
This works for me and allows the build to complete. I'm not currently
sure if HOST_WIDE_INT_PRINT_C needs similar treatment.
I've created PR22594 - http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22594
Many thanks.
Dave
