Hi Kai,
I agree that the things I wrote does not have much sense for people
that spent years in developing GCC, like you and most of the people
here are. I am very very very new in both using gcc and in its
internals. The first time when I was building cross platform gcc I
really did it from the
Hi,
I am working on gcc-4.1.1 and Itanium architecure. Today I try to add
a function call before each ld instruction. The method I use to
achieve this goal is to modify final_scan_insn() in final.c: before
calling get_insn_template, I add codes to check whether the insn
matches a template that wil

Make sure that the called function restores the original state of the
program before it returns.

Andy, you must handle the calling convertion when inserting a function
call. It includes the saving and restoring of caller registers and the
proper passing of params.

The doc on --enable-checking at:

contains:
--enable-checking=list

describe what the flags mean. Could so

Hi, Patrice,
I don't know about inserting call at the basic block level, but I am
quite sure inserting calls at the function level could be done by
aspect-oriented-programming (AOP).
For example, we used our project, AspectC compiler (www.aspectc.net), to
weave in following aspect into gcc,

GCC 4.1.2 RC2 is now available from:
ftp://gcc.gnu.org/pub/gcc/prerelease-4.1.2-20070208
and its mirrors.
The changes relative to RC1 are fixes for:

Another solution is to add the instrumentation earlier, and use expand_call.
Thanks for your hints. Is that means doing intrumentation at the "RTL

expand_call is a function in the calls.c file. It knows how to do
function calls correctly. If you use this, then registers will be saved
and restored correctly.

Hi,
Division by zero is undefined. We chose to keep it:
http://gcc.gnu.org/ml/gcc-patches/2001-06/msg01068.html
But now gcc seems to optimize it away. For the following function:
$ cat t.c
#include
void foo (int rc)
{
int x = rc / INT_MAX;
x = 4 / x;
}
$ gcc -O2 -S t.c
$ cat t.s
.fi

I believe we still keep division by zero in general. In your example
it gets optimized away
