Hi,
I want to get the profiling data of an application in linux. Now I am
using -pg options of gcc for generating the profile data. then used
gprof for generating profiles. Here I am getting only in terms of
seconds. But I want in millisecond resolution. can anybody help me.
Thanks & regards

I haven't looked at the new branch yet, so forgive me

Good morning everyone!
Here's a simple testcase that illustrates what I'm observing in gcc-3.3.3
--
extern void abort (void) __attribute ((noreturn));
int foo (int a, int b)
{
if (a > 25)
abort ();
return (a + b);
}

How can this possibly be? When the sibcall is done, the current
function's stack frame is removed.

Because generally losing unwind information from noreturn calls
is a lose when it comes to debugging.

The lower-subreg patch that Richard Henderson posted, and that comes
up again and again from time to time, may also help. It does require
a bit of hacking in the MDs (mostly removing the DImode patterns for
logical operations since the middle-end is able to synthesize them on
its own).

Using libmudflap to test a program that uses libxml2, I found that if
a program access a constant pointer in a non-instrumented library,
mudflap thinks that a read violation has occurred.
A simple test that illustrates this is:
a.c:
-
char *p = "abc";

Did the compiler give you a warning about inability to track the

No. Not even with -Wall -O2.

Hello again Daniel and all!
I'm still working on building the iWMMXt/EABI/NPTL toolchain. I've got to the
stage where I have everything built upto the final linking of glibc. Sadly
despite making a lot of progress and fixing many problems I am now stuck.
As I previously discovered the current g

has been an explosion in the time spent during the alias analysis phase.
using cplusplus-grammer.ii, it use to compile on my machine in about 55
seconds, and its now up to about 150 seconds.
A quick gprof indicated about 60%

Take the following C code:
typedef long atype[];
typedef long atype1[];
int NumSift (atype *a, atype1 *a1)
{
(*a)[0] = 0;
(*a1)[0] = 1;
return (*a)[0];
}
Shouldn't the aliasing set for the type atype be the same as atype1?
In NumSift, shouldn't the store to (*a1)[0] interfere with (*a)[0] s
