Hi!
I'm porting GCC to a software VM with 32 32bit registers, and 32 64bit
registers.
The 64bit registers are used for DI, SF and DF mode. Pointers and QI, HI and SI
modes are handled with 32bit registers.
The first 8 32bit parameters of functions are passed into the first 8 32bit
registers (g0.
Perfect, thank you!

It did bootstrap effortlessly for me, once I logged off to clear hung

There is a patch here:

Not sure if it has been approved. I sort of thing that

Ian suggestion worked perfectly, thanks. Can you tell me the macro/function
name to look up
to work out the secondary reload you're mentioning?

It should be __si_class_type_info in my case.
Beautiful! Many thanks Dave :-)

Consider a class hierarchy with single inheritance, as follows:
struct A {
virtual ~A() = default;
}
struct B : public A {
virtual ~B() = default;
};
and
A* p = new B();
then how can I get the type_info object of the base class of B?
Or, in other words, how do I enumerate the chai

I suggest you look at the dumps for i386 to see
Hi,
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40004 was a bug report that I
filed on the missing plugin headers.
That is now resolved - the headers are installed. I've closed the bug report.
However I'm not sure how my application / buildsystem is meant to find the
headers. Is there a way gc
