Hello all,
I am doing a private port in GCC 4.4.0. For my target the following
are the alignment requirements:
int - 4 bytes
short - 2 bytes
char - 1 byte
pointer - 4 bytes
stack pointer - 4 bytes
i am not able to implement the alignment for short.
The following is are the macros that i used fo
Hi you!
I'm a C++ developer on Linux. I want you show me the ways to install
both GCC 4.1.2 and GCC 3.2.3 on my Linux.
Thank you very much!

This question is out of scope for this mailing list which is about
the development _of_ GCC, not the development _with_ GCC.

In current gcc the order of options -D and -U is significant. The Single Unix(r)
Specification explicitly specifies that the order should not matter for the c89
command. It reads (cited from version 2, which is ten years old):
-D name[=value]

Ira and Dorit,
Is there any chance that PR33113 will be addressed for
gcc 4.5? If I recall correctly, it was one of the last
major issues with vectorization in gfortran that wasn't
addressed yet. Dorit made the following comment back in

The simple solution is to either add a prefix to variable names, or to
add a prefix to register names. In ELF, the convention is to not

Yes, I'm also looking at Coccinelle and TreeHydra.

Hi Jim,
that seems to be a promising solution.
If I keep the prefix "_" for a global variable , there is a problem in
accessing it in gdb...let me explain you with an example
Eg: file1.c
int a = 10;
int main()
{
int b =10;
int c;
c = add( a , b);
return 0;
}
file2.c
int add( int x, int y)

I was improving tree aliasing for pointers by adding support a+1 and a

if the accesses do not overlap. This does extra disambiguation
for mixed/pointer accesses

2) Is this a bug?
I think it's a bug in the specification.
User-specified CFLAGS are always passed last in the Makefiles (at least
for Automake, but it is a good practice in general) so that the user can
override options like -D, -U, -O, -g, -f, -m
