[RHONDA VINCENT]

i am receiving the following compile errors:

stray '\274' in program
stray '\210' in program
stray '\275' in program
stray '\' in program
stray '\300' in program

Can you tell me what these errors mean?

Thanks,

OK, so you believe this.  So what happened when you tried it?

IMO, that's the wrong way to do it.  If you *really* need to use
nonstandard paths we provide args like -Isystem and -nostdlib.  But
generally gcc is configured for a particular target environment and
things will go wrong if you try to change things under its feet.  If
the libraries and include paths are very similar, you might get way
with it.

Hi,

I have some query regarding the way gcc resolves the search directory
for standard libraries like libc. When I run  command  "gcc -v test.c" i
get the following output

Is there anyway i can change the default search location. 

I believe that by passing my own spec file to gcc as gcc
-specs=<myspecs> test.c, i can change the default include path and also
the path to look for for crt0.o etc.

You can't get cycle-accurate life time info in the register allocator
unless you have a combined register allocator and instruction scheduler.
 We don't have that.  They are separate passes.  Combining them is
difficult.

We do have life time info at the RTL instruction level, but this info
tends to be either internal to each register allocation pass, or not
specific enough for your needs.  You may or may not be able to do
anything with this info.

The register allocator does not emit instructions (other than reloads
emitted by reload), so you can't do this in the register allocator.  You
probably have to do this in final, when RTL is emitted as assembly language.

You might be able to do something useful with REG_DEAD notes, but they
are probably not guaranteed to be accurate when we get to final.  You
could try scanning following instructions for REG_DEAD notes, to see
where registers die.  Worst case, you might have to create your own life
time info by scanning all of the RTL instructions in a function.  You
could do this in a MACHINE_DEPENDENT_REORG pass.

You will probably need to spend some time studying the gcc sources in
order to do anything useful here.

[Balaji V. Iyer]

Hello Everyone,
    Greetings! I apologize ahead for asking an non-specific question. I
have a question about the liveness analysis. This is what I wanted to
do.

I want to check to see if an instruction is live after a certain number of
stage. (eg. 3 cycles)

if (INSN is not live for more than 3 cycles)
   Mark it as "not_live" (NOT the same place as dead code marking)
else
   Mark it as "live"

Pass this "live/not-live" flag to the register allocation process so that
it can output instruction in such a way (please see example below) (I want
this information to be passed into .md stage)

if (live)
  print "add.live r1,r2,r3"
else
   print "add.notlive r1,r2,r3"

I would also like to do it on the OpenRISC processor. Also, would like to
NOT change the GCC sources as much as I can.

I would appreciate if anyone could point me in the right direction to go
about doing this.

Thanking You,

Yours Sincerely,

Balaji V. Iyer.

PS. CC's greatly appreciated.

Hello Zhou,

you should compile C++ code with "g++", not with "gcc".

This is the output when running "g++ temp.cpp":

In file included from
/var/tmp/gcc-3.4/lib/gcc/i686-pc-linux-gnu/3.4.0/../../../../include/c++/3.4.0/backward/complex.h:31,

for the <X.h> header for C++ includes, or <iostream> instead of the
deprecated header <iostream.h>. To disable this warning use -Wno-deprecated.


This warning can be easily omitted if you do

/* ---------------------------------------------------------------------- */

#include <cstdio>
#include <complex>

using std::complex; 

/* ---------------------------------------------------------------------- */

Be aware, that there's also complex number support in C99 header "complex.h"
- which is a completely different header than C++'s "complex".

Cheers.

help with gcc

[steve goodwin]

I am trying to compile some ansi C source on a HPUX 10.20 system.

The HP ansi C compiler uses the +z option to create position independent 
code.  I have tried using -shared, -fpic -fPIC but I still get the 
following message from the linker:

ld: DP relative code in file API_test_fns.o - shared library must be 
position
    independent.  Use +z or +Z to recompile

Any idea how to get position independent code from gcc?

Thanks for your help

No, gcc installs into /usr/local only, if configured with that prefix.
