Hi, I'd like to know if the current behaviour of -Winvalid-pch is the
intended one, mainly because gcc prints the message saying that the pch
is invalid even if later it finds a valid one.
Suppose that one project builds the pch for several build types (debug,
release...) in the same directory. In
Hi,
I noticed, that the builtin functions for mingw (at least for 64-bit
Windows) are not correct in return type. See msdn
http://msdn2.microsoft.com/en-us/library/xwy0k9bb.aspx.
The return type for those targets (i?86-pc-mingw32 and x86_64-pc-mingw32)
is a intptr_t, but a 'int' for other targe

You could just call disable_builtin_function ("execl") and similarly
for other exec* family functions from i386/mingw-c.c

When you mean scheduling of the instruction, does it mean that the
register allocation for ASM is not that advanced than it is for a
builtin ? For instance the use of register classes, for the instruction.

We've encountered a bad code generation problem because of the way that
resource.c:mark_set_resources is ignorant of COND_EXEC patterns, which
ultimately results in a delay slot instruction clobbering a register

Snapshot gcc-4.2-20080130 is now available on
ftp://gcc.gnu.org/pub/gcc/snapshots/4.2-20080130/
and on various mirrors, see http://gcc.gnu.org/mirrors.html for details.
This snapshot has been generated from the GCC 4.2 SVN branch

I'm debugging an EH failure on m32c-elf (-mcpu=m32c). The test case
is this:
extern int U();
void *ra;
main()
{
foo((ra + U()) - 1);
}
In the context of the bug, sizeof(void *) is 32 (well, PSImode = 24
bit) and sizeof(int) == 16. U() returns zero in this example.
So, the call is this:

Hi,
I am a new contributor to GCC. I am interested in the following project from
the beginners webpage:

I would like to know what's the status of this item? Is this still an open
project? Doing a quick search on the mailing list archives I was only able

There is no integer to pointer promotion. You're adding an integer to a

See: http://www.linuxonly.nl/docs/2/0_Page_1.html
It's very clear, you should use a type cast:
result = concat ("(", cond1, ") && (", cond2, ")", (char *)NULL);
instead of:
result = concat ("(", cond1, ") && (", cond2, ")", NULL);

It says:
This is because NULL is not of the right type: it is defined as
integer 0 instead of a pointer with the value 0.
Except that is wrong from what the C99 standard says abo

Yes because the header defines NULL incorrectly. Which was the whole
issue in the first place.
