 Hello Madam/Sir,

I came across this problem on using gcc-3.2.2 on hp-ux 11 platform

I am not able to build binary on hp-ux.

On using command line options in script and executing the script using ant.

came across the following error

[exec] ../lib/x_yacc.c: In function `x_yyparse':
      [exec] ../lib/x_yacc.c:36808: Internal compiler error in
output_cbranch, at config/pa/pa.c:5303
      [exec] Please submit a full bug report,
      [exec] with preprocessed source if appropriate.
      [exec] See <URL:http://www.gnu.org/software/gcc/bugs.html>

[Phani Pavan]

We are trying to develop a tool to check the code by reading the compiler trees generated from gcc. While parsing through the trees, we found the following issues. Please suggest us, if there is any utility, which gives us the data that directly reflect the user code with out doing any optimization or processing of the user code. 

1. const is coming only for variables in form of read_only_flag. With this we are only able to identify read only variables. But we are not able to identify pointers that are pointing to constant data like "const char *p."
2. "Implicit data types could not be found Ex: var = 7; This var is implicitly treated as a integer variable."
3. "Repeated data definitions cannot be found. They will be overWritten.
	int a;
	int a=8;
The second declaration has an initializer, so it ignores the previous declaration.
4. For a conditional statement like (i>0)? i:-i is treated as a abs_expr (Absolute Expression) instead of an conditional expression.
5. If there is an else statement with a NULL body, then it will be ignored.
6. There is no differentiation done between extern declaration and a forward declaration for a function.
7. For an inline function declaration, the inline information for the function is missing in the tree.
8. While iterating multiple input file, with top_lev_main, it is failing inside stor-layout.c
9. The function declaration comes as default at the definition, even if there is no declaration for the function.
10. If the function definition follows a function declaration, then the declaration is getting overwritten by the definition.
11. Sometimes in function declaration, a void member is padded at the end of the function argument list.
12. If the function takes in variable number of parameters ( … ), this information is missing in the trees.
13. For function declarations, the argument name information is missing.
14. "In a Compound expression, if there are multiple expressions, only the first and last expressions are considered for adding in the tree, as the compund expression can have only two arguments like (a+2, b+3, a+b+c): Will be taken as (a+2, a+b+c)"
15. "Size of construct: If there is a structure type definition inside a type declaration like struct, 
struct abc_
{
    struct
    {
        int a;
        int b;
    }
    int a;
};
In this case the unit size of the record type includes the size of the structure definition even though there is no member defined for the internal structure. This case gives a difference in size when we attain through sizeof() operation."
16. "in-built functions can not be traced as the tree is constructed using the information. The sizeof construct is replaced by its value in the tree."
17. The enumeration Constants are replaced by their values in the tree.
18. Tree information in a long variable ( for ex if a function call is made func(20l) it is not possible to recognize these situations.)
19. "All the implicit conditional statements are expanded in the tree. If ( i )  => if ( i != 0 )"
20. An expression like w < 20 will be treated as w <= 19
21. Implicit  cast and explicit cast of data types could not be differentiated.
22. Prefix and postfix ( ++, -- ) are optimized in iterative statement, in which they are swapped.
23. All the constant expressions are evaluated in the tree.
24. "Compound assignment operators are expanded to simple operators. a>>=b is expanded to a = a >> b;"

Thanks in advance,
Phani

What is your compilation line? Obviously you forgot to link to the
openssl library. Adding -lssl to the end of your compilation line should
help. This flag will tell the linker to link with the ssl library.
Whenever you use a library, you have to link to it.

There must be some good documentation with the openssl package. Else,
searching "openssl tutorial" or something like this on www.google.com
should give you good results.

The code is here as an attachment. I would be grateful if someone 
helps me, I still have problem with serv.cpp and inetdserv.cpp but 
I will try to debug them myself.

2. It would be of great help if someone can tell me a link where I 
can learn how to write applications using Openssl Library.

Thank You very much,
Yours Sincerely

This means that you haven't #defined these macros or included the header
files which declares close().

It looks like you've copied this code out of one of the ssl demo files;
you can find definitions of the CHK_SSL/NULL/ETC at the top of cli.cpp,
inetdsrv.cpp or serv.cpp (just above the main function). You should copy
these lines into your program after the openssl includes but before
main(). You should also try and understand what they do rather than just
use them blind!

If you type 'man close' on your system then it should tell you which
header file to include for the definition of close() (probably
unistd.h).

Good luck,
Rup.

Hi,
I need some information about how the GCC compiler handles inline assembly
... More specifically I need info on :
1) does the compiler parse the individual assembly instructions present in
the assembler template; where in  the source code of GCC  does this
happen?
2) are these instructions inserted into the intermediate representation of
the rest of the code ? where in the source code of GCC does this happen ?

Thanks for the information.
Regards,
Navin
