I am just porting Ethernut (http://www.ethernut.de) to ARM platform.
I am using WinXP with newest Cygwin and a downloaded precompiled GCC
Environment from http://www.ariusdsp.com/gnuarm/gnuarm.html.
Compiling worked for a few hours with a lot of files without preblems, but
when reaching tcpsm.c, i get the segmentation fault. Position is function
NutTcpProcessSyn. Error is 100 % reproducable. When i completely comment out
the function it happens at another functions... Just unzip the attached zip-
file and call "make". The last line when compiling are:
.
.
.
make -C net
make[1]: Entering directory `/cygdrive/d/internet/ethernut/ethernut-
3.3.2/nut/net'
arm-elf-gcc -c -mcpu=arm7tdmi -DCOMPILE_FOR_ARM -save-temps -Os -Wall -Werror -
Wstrict-prototypes -Wa,-ahlms=tcpsm.lst -I../mod/include_arm -I../include_arm
tcpsm.c -o tcpsm.o
tcpsm.c: In function `NutTcpProcessSyn':
tcpsm.c:263: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
I am not a compiler guru, so please tell me which information you additional
need from me.
Greetings,
Martin Maurer (capiman@clibb.de)

I narrowed the error to following statement:
ntohl(th->th_ack);
When ntohl is called, compiler is crashing).
ntohl is defined as __byte_swap4(x), which is again defined as
#define __byte_swap4(val) \
(((val & 0xff) << 24) | \
((val & 0xff00) << 8) | \
((val & 0xff0000) >> 8) | \
((val & 0xff000000) >> 24))
I tried extracting the parts from the big environment out to a single C file,
but then i can compile with a segmentation fault. But wasn't able to use the
same parameter when calling gcc.

I have minimalized the code to one small C file (no includes !)
and still can reproduce the error:
(perhaps the problem is, that the assembler code is not yet ported,
but this is still no reason to throw an segmentation fault...)
C File contains:
static inline long __byte_swap4(long val)
{
asm volatile(
"mov __tmp_reg__, %A0\n\t"
"mov %A0, %D0\n\t"
"mov %D0, __tmp_reg__\n\t"
"mov __tmp_reg__, %B0\n\t"
"mov %B0, %C0\n\t"
"mov %C0, __tmp_reg__\n\t"
: "=r" (val)
: "0" (val)
);
return(val);
}
void NutTcpInputOptions(void)
{
unsigned long c = 0;
c = __byte_swap4(c);
}
You can compile and reproduce the error with:
arm-elf-gcc -c -mcpu=arm7tdmi tcpsm.c
Hope it helps !
BTW: I have tried out to feed the same thing into normal GCC 3.3.1 for x86,
also a version compiled for cygwin and get also an error (segmentation fault
but a bit another text):
tcpsm.c: In function `__byte_swap4':
tcpsm.c:2: internal compiler error: in print_operand, at
config/i386/i386.c:6904

The code is invalid.
if CODE is 'D', then the X is a condition operand and the instruction
should only be executed if the condition is false: however, if the mode
of the comparison is CCFPEmode, then always execute the instruction -- we
do this because in these circumstances !GE does not necessarily imply LT;
in these cases the instruction pattern will take care to make sure that
an instruction containing %d will follow, thereby undoing the effects of
doing this instruction unconditionally.

Martin, is this a regression? Did this work on older GCC releases?

While it might be possible to fix this specific instance, I see no realistic way
to make the compiler robust against this sort of junk input.
Asm statements are generally fairly fragile, you need to know what you are doing
with them -- consider the crash as your diagnostic :-)
