mpfr issues when Installing gcc 3.4 on fedora core
Hi I have tried everything any page might say on this, still stuck. Any help would be great Hi all I am trying to install 3.4 on my AMD turion 64 machine with fedora core. But run into messages like this on gmake. Configure is fine libbackend.a(builtins.o): In function `fold_builtin_cbrt': ../.././gcc/builtins.c:7175: undefined reference to `mpfr_cbrt' libbackend.a(builtins.o): In function `fold_builtin_exponent': ../.././gcc/builtins.c:8183: undefined reference to `mpfr_exp10' libbackend.a(builtins.o): In function `fold_builtin_1': ../.././gcc/builtins.c:9400: undefined reference to `mpfr_erf' ../.././gcc/builtins.c:9406: undefined reference to `mpfr_erfc' . Installed mpfr and gmp and verified mpfr.h and gmp.h exist in /usr/local/include and libmpfr.a , libgmp.so etc exists in /usr/local/lib I have tried the following things 1../configure --with-mpfr=/usr/local/lib --with-gmp=/usr/local 2. ./configure --with-mpfr-build= --with-gmp-build= 3. --with-mpfr-lib, --with-mpfr-include, 4. Update LD_LIBRARY_PATH to also include /usr/local/ 5.--enable-languages=c,c++ --disable-mpfr I just want a working gcc 3.4 and I really dont care for this precision library. Any sugesstions on how to get it to work ... thanks dz
Re: mpfr issues when Installing gcc 3.4 on fedora core
The only warning it reports is this immediately after detecting gmp and mpfr *** This configuration is not supported in the following subdirectories: target-libada gnattools target-libgfortran target-libffi target-zlib target-libjava zlib target-libobjc target-boehm-gc The other suggestions u have said were typos: I have used LD_LIBRARY_PATH with /usr/local/lib and --with-mpfr=/usr/local --with-gmp=/usr/loc I got the 3.4 sources from the gcc site. Is there a way I can get prebuilt binaries ? thanks dz On 1/3/07, Joe Buck <[EMAIL PROTECTED]> wrote: On Wed, Jan 03, 2007 at 08:11:35PM -0500, drizzle drizzle wrote: > Hi > I have tried everything any page might say on this, still > stuck.

I suspect that this is the root of the problem. I also think that gcc should be more robust in dealing with an mpfr.so not on the LD_LIBRARY_PATH that it has already found via configure, but that's another story. --disable-mpfr is not an option; mpfr is required now. > I just want a working gcc 3.4 and I really dont care for this > precision library. Any sugesstions on how to get it to work ... If you want 3.4, then get it from ftp.gnu.org or a mirror, and you won't need mpfr.
Re: mpfr issues when Installing gcc 3.4 on fedora core
Not 4.3 but 3.4 yes the older version. And I built and installed mpfr and gmp. gmp4.1 and mpfr 2.2. I dont have a /usr/local/lib64 on my system. Did my mpfr/gmp install incorrecly ? dz On 1/3/07, Matt Fago <[EMAIL PROTECTED]> wrote: You do mean gcc 4.3 right (either a snapshot, or from svn)? Since you're running on x86_64, do you know that the libraries are the correct bitness (running 'file' on the mpfr and gmp libraries will tell). By default gcc on x86_64 will build 64-bit, but libraries in /usr/local/lib should only be 32-bit (versus /usr/local/ lib64). The linker will ignore any 32-bit libraries when linking a 64- bit executable. How did you install gmp/mpfr (note the package from fedora is broken -- very old)? It took me quite a while to get 4.1 with fortran installed on RHEL until I got this all sorted out (I was new to multilibs). I just upgraded to fc6 and was able to install gcc from svn once I used -- with-gmp-lib=/usr/local/lib64 (etc for include and mpfr) and setting LD_LIBRARY_PATH=/usr/local/lib64 appropriately. Alternatively one could (carefully!) setup /etc/ld.so.conf and run ldconfig (I did this on RHEL). I might be able to help tomorrow AM (US mountain time) if you email me directly. FWIW, I understand the reason to keep mpfr out of the gcc tree, but not doing so makes gcc more difficult to bootstrap for a novice such as myself. Fedora's outdated gmp/mpfr package doesn't help either ... - Matt
Re: mpfr issues when Installing gcc 3.4 on fedora core
I am wondering if my all my troubles stem from mpfr not being installed properly .. When I configure mpfr I get the following warning. Cud this be an issue ? checking if gmp.h version and libgmp version are the same... (4.2.1/4.1.4) no configure: WARNING: 'gmp.h' and 'libgmp' seems to have different versions or configure: WARNING: we cannot run a program linked with GMP (if you cannot configure: WARNING: see the version numbers above). configure: WARNING: However since we can't use 'libtool' inside the configure, configure: WARNING: we can't be sure. See 'config.log' for details. And as matt suggested if mpfr is not needed by 3.4, how can I configure it that way. --disable -mpfr did not help. thanks for all the hints so far dz On 1/4/07, Vincent Lefevre <[EMAIL PROTECTED]> wrote: On 2007-01-03 22:19:16 -0500, drizzle drizzle wrote: > Not 4.3 but 3.4 yes the older version.

I don't think MPFR install libs in .../lib64 (everytime I tried on an x86_64 machine, it didn't, but I was using another prefix directory, in my $HOME). Anyway, MPFR is based on the autotools. So, it would be a problem with the autotools.

It is an annoying problem that MPFR and GMP follow inconsistent rules. For example, if you configure the current version of both on a sparc-sun-solaris machine, GMP will build a 64-bit version and MPFR will build a 32-bit version.

Invariant division

gcc preprocessor
Hi Can some one tell me if gcc preprocessor can support in some way the following features 1. Repeating a block a certain number of times 2. Multiline macros with new lines 3. Setting a symbolic constant inside a #define thanks dz
Re: gcc preprocessor
Ok can you tell me what directives does it provide to do what I have said . And I am not a beginner to gcc. 1. Repeating a block a certain number of times for example repeat expr foo() end Then you can call expr 5 to have foo called 5 times. 2. Multiline macros with new lines Using #defines with escape characters is very clumsy and it just concatenates it into one line as far as I understand. Please correct me if that is wrong. 3. Setting a symbolic constant inside a #define for example #set a i+1 foo(a) Thanks for any help dz On 4/18/07, Joe Buck <[EMAIL PROTECTED]> wrote: On Wed, Apr 18, 2007 at 09:07:07PM -0400, drizzle drizzle wrote: > Can some one tell me if gcc preprocessor can support in some way > the following > features You are asking a beginner C programming question. gcc's preprocessor does what standard C preprocessors do.
Re: gcc preprocessor
Any developer sense on what it might take to extend the gcc preprocessor to do these ? I have some experience with gcc front end. I am especially keen abt multiline macros, so that the lines can be on separate lines. Any neat trick that can accomplish this by using #define ? dz On 4/20/07, Joe Buck <[EMAIL PROTECTED]> wrote: On Fri, Apr 20, 2007 at 01:27:48PM -0400, drizzle drizzle wrote: > Ok can you tell me what directives does it provide to do what I > have said . And I am not a beginner to gcc. The answer is that gcc provides what the C standard specifies and nothing more. You appear to want a more complicated macro-processing language. You'll need to look elsewhere; m4 is one possibility, though I'dm not a fan of it.
debug output and register allocation
Hi I am wondering how gcc handles producing debug information for automatic variables that do not reside inthe stack.For example when say register allocation decides to assign a particular register to a variable or say it decides that the value is a constant. Can some one point me to the relevant pieces of code ? thanks for any pointers dz
debugging quality and gcc
Hi I am wondering if from a developer perspective some body can tell me what debugging quality to expect when using -g with O3. Especially when the following happen 1. When a variable resides in multiple locations in different scopes such as different registers. If this works very well, I am wondering how gcc accomplishes this? 2. A function is inlined. 3. Constant propagation. Due to constraints of my use, I have to generate code without the frame pointer. thanks dz
Annotations in tree
Hi, I am trying to find out how to insert annotations for certain array references identified in tree-loop-linear.c so that when converting to RTL they can be handled differently. I find that simply inserting a flag in the tree node is not enough as optimizations later on can lead to the node being removed. Can any tell me what else can I do ? I will appreciate all help dz
Re: Annotations in tree
I am not sure if I unerstand ...can you elaborate please ? So what I need is if I identify say a reference a[i] inside a loop, I want to identify the corresponding RTL. What I find now is that these get transformed for example D.1065_17 = a_matrix[i_24][k_30]; // I have identified this sum_12 = D.1065_17 + sum_31; gets coalesced back into sum = a_matrix[i][k] + sum; before it is expaned into rtl.. How do I keep track that it is indeed the same array reference though it has gone through some transformation. ( One another tranformation is generating a pointer to it instead of using the array).

Re: Annotations in tree
What doesnt exist very long - the references ? At RTL level, I just want to insert a counter for each one of these. One alternative I saw is inserting a dummy functiion call. Would that work ? If so, for a given name, how do I create a corresponding function expression for it ? thanks for the answers On 7/26/05, Daniel Berlin <[EMAIL PROTECTED]> wrote: > On Tue, 2005-07-26 at 18:39 -0400, drizzle drizzle wrote: > > I am not sure if I unerstand ...can you elaborate please ?

Re: Annotations in tree
tree level is fine too, it was just that the RTL level already had a host of counters being inserted. One implementation question if I may ask, so at the tree level how do I create a call to my function. I know how to insert it into the tree but some how all my creations attempts with build_function_call fail. thanks once again ...

Inserting a call statement
Hi
I am trying to insert a function call "foo" inside the tree list.
Inside this particular loop
for (bsi = bsi_start (bb); !bsi_end_p (bsi); bsi_next (&bsi))
{
//if a particular condition is satisfied I do the following
tree id = get_identifier ("foo");
tree t = build_function_type_list (void_type_node,NULL_TREE);
tree decl = build_decl (FUNCTION_DECL, id, t);
tree call = build_function_call_expr (decl, NULL);
bsi_insert_before(&bsi,call,BSI_CHAIN_END); // I have tried
BSI_NEW_STMT
}
Although the node is created properly, an assertion in
tree-flow-inline.h fails. Can someone help me identify the issue here.
i will appreciate that
thanks
Re: Inserting a call statement
Its inside this function
static inline var_ann_t
var_ann (tree t)
from the error dump itseems to the following assertion
gcc_assert (DECL_P (t))
thanks

Re: Inserting a call statement
Thanks for your help. I am attaching my patch. Most of the code dont
modify anything. The code I am talking about is ia small piece in
tree-data-ref.c in a function insert_annotations. The only
modification in the rest of the code is that an extra variable refid
is set for particular array references. This variable triggers the
annotation. Apart from that my guess is the rest of the code can be
ignored. I would appreciate any suggestions.

Insertng a call function
Hi
I am inserting a call stmt in linear_transform_loops. Al though
the call statement gets inserted , the compilation breaks. Can some
one help me identify if I am missing some information in the call
node that I create (thanks Daniel for all the help until now)
here is the set of statements I have used
tree id = get_identifier ("foo");
tree t = build_function_type_list
(void_type_node,NULL_TREE);
tree decl = build_decl (FUNCTION_DECL, id, t);
tree call = build_function_call_expr (decl, NULL);
bsi_insert_before(&bsi,call,BSI_NEW_STMT);
...Here are the tree dumps of the statement which gets inserted

But this breaks with the follwoing path

I will really appreciate any solutions or ideas or debugging tips.

Re: Insertng a call function
Hi
I updated my function call creating statement based on how
gomp_parallel_end is inserted in the gomp branch. It still breaks. I
have provided the function declaration in the file, just want to
insert the call. Any further suggestions. My whole objective is to
mark a few particular
tree statements (array references actually) and carry them over to RTL
form. So I am trying to insert a call before these references which
when seen in RTL will tell me my references of interest. Any
suggestions on some other ways I an try apart from this call
insertion?
here is my upated piece of code to insert a function call
tree fn, type;
type = build_function_type_list (void_type_node,
void_type_node, NULL_TREE);
tree id = get_identifier ("foo");
tree fn_decl = build_decl (FUNCTION_DECL, id, type);
DECL_EXTERNAL (fn_decl) = 1;
TREE_PUBLIC (fn_decl) = 1;
DECL_ARTIFICIAL (fn_decl) = 1;
TREE_NOTHROW (fn_decl) = 1;
tree call=build_function_call_expr (fn_decl, NULL_TREE);

Re: Insertng a call function
Could it be that it being done lower in the pass unlike insertions in
tree-profile, gomp - some ssa defintion information is missing. The
reason I have been led to think is because it fails
register_new_defintions. I would appreciate any suggestions.

Using Alias analysis
Hi . I want to use gcc's alias analysis in a standalone way. What I observe is that a lot of the information is hidden because of additional temporaries that have been generated. Can any one suggest as to if there is a simple workaround to this ? To illustrate what I am saying for a stmt heap_ptr= (int**) malloc the alias analysis tells me D.1072 points to malloc and heap_ptr points to anything. I would have liked to see heap_ptr points to malloc. Any way I can get that information. I would appreciate any idea/suggestions ... dz
