I am very happy to see that gfortran from current gcc snapshots can
successfully compile an 18000 lines Fortran 77 numerics program I wrote.
Results are indeed the same as obtained with other compilers (g77, PGI,
ifort), and also execution speed seems roughly comparable, although I
haven't yet

You're confused. This is a middle-end mis-optimization. However, it is

At the risk of stating the obvious, those parentheses after "GTY" look
unbalanced to me.
Of course, these were fixed very soon :)

gengtype doesn't support anonymous structures or unions, you need to
give them a name. (I don't remember if this is simply a limitation of
the existing implementation or if it's more fundamental.)
OK, naming them has helped. Out of curiosity, why does following

I'm having trouble understanding part of the machine description
for PowerPC floating point operations.
There are a number of places where there are pairs of templates,
one with define_expand, the other with define_insn or
define_insn_and_split. For example, the fp negate templates:

Having *implicit* pointers be *a specific* size certainly is. Made

All the above and more. It is a source release of GCC.

Hi,
for the following test case:
struct A {
virtual int x () {return 1;}
};
struct B: A {
virtual int x () {return 0;}
};
struct C: B{
using A::x;
};
int main()
{
C c;
return c.x();
}
all g++ 4.x will return 1
It seems C++ standard would want to see 0.

Hi,

doing that, I am not clear about my issue. It goes..
I want to contribute to GCC dev and I will start at
basic projects for beginners.

Thanks DJ & Mike for your quick replies.
This is to summarise my plan so that others can
guide/help me.
Considering that GCC has no garbage code (Right?
Mike!) I would like to rephrase my task as removing
dead code, unwanted code, any fat that we can get rid
of from the source tree ..
