Hi,
if I dump the tree of the following C program,
int main() { volatile int i; i = 5; return 0; }
I get (-tree-original):
{
volatile int i;
volatile int i;
i = 5;
return 0;
}
However, if I apply my volatile-in-Fortran patch [1] and compile
integer, volatile :: i; i = 5; end
then t

I think you will also want to give DECL a type which is
volatile-qualified:
build_qualified_type (original_type, TYPE_QUAL_VOLATILE)

Hello,
I am trying to get gcc to optimize an inner math loop. The first part
of the loop computes a single precision float expression (which may or
may not be NAN), and the second part sums all of these results into a
double precision total:
Conceptually, the code is:

In general, you will want to check the Makefile and see what it uses
to run aclocal.
In java for example, they use:
ACLOCAL_AMFLAGS = -I . -I .. -I ../config
So, in fact, I think you regenerated the file incorrectly.
The original author of this patch said he sent his copyright assignment. I
only did minor modification to his work so I don't I think I should send
it too.

I already did a bootstrap and check to be sure it worked right when I

This may be a FAQ, but I was unable to find the answer on the web, so I
hope people will forgive me asking it here.
I recently tried to use a MinGW GCC (built from FSF sources) to link
with a .lib file that had been compiled with MSVC, and got link-time
errors about _chkstk. After some search

It defines __chkstk as an alias for _alloca instead. My guess is that
this is a mistake.
There are other MSC library functions t

There are other MSC library functions that MinGW doesn't provide, so
other libraries may not link even with a _chkstk alias.
Got a list?
