[Bug libfortran/21185] libgfortran unusable for cross-testing for newlib targets
--- Comment #8 from fxcoudert at gcc dot gnu dot org 2007-09-13 09:33 --- I'm coming back to that issue... (In reply to comment #4) I guess we could try to provide a graceful degradation for such systems... The use of dup() can probably be avoided if dup() isn't available without too much degradation in the library features. I still think it's better than nothing. It will gives weird results when people start closing preconnected units, but we can document that behaviour. Otherwise, we can use another technique to create new descriptors for stdin/stdout/stderr, but I can't think of something that would work easily. access() can probably be emulated, or at least its basic features. libgfortran only use it with modes R_OK, W_OK and R_OK | W_OK. These uses can be emulated with calls to open(). For ftruncate(), however, I don't see how to make it work. ftruncate() is now protected by HAVE_FTRUNCATE, so this one shouln't be a problem any more. -- fxcoudert at gcc dot gnu dot org changed: What|Removed |Added CC||fxcoudert at gcc dot gnu dot ||org AssignedTo|unassigned at gcc dot gnu |fxcoudert at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2007-01-05 10:06:52 |2007-09-13 09:33:48 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21185

As I need to port my project to vs2005, and the source code contain some UTF-8 string which is not suitable to represent by escaping, I have to add UTF-8 BOM to make vs2005 recognize it. But after I added the UTF-8 BOM, gcc can't compile it anymore, even using -finput-charset=UTF-8, it still say error about \357 \273 \277. Can you fix this problem? escaping is troublesome as too many of them and make the source code unreadable. vs2005 surely need UTF-8 BOM. While gcc can't accept UTF-8 BOM presently.

otherwise, compile with the -Wall option. This will catch a bunch of shady (and
probably buggy) code automatically.

And wait, it gets worse! Just compile this sucker with -O2 optimizations and
you get RANDOM RETURN VALUES from the call of Func1 (this is because Func1

When comparing run time on some (floating point) CPU intensive code, we find that Intel's ICC (9.1) compiler runs significantly faster (30 - 50%) for some programs - this seems to stem (large) part from ICC's ability to take advantage of #pragma ivdep. There may be some other differences of course. Tests were run using gcc 3.3.3 - re-compiling relevant key code with gcc 4.1.2 did not make any real change.

[Bug c/33427] New: Support of #pragma ivdep
When comparing run time on some (floating point) CPU intensive code, we find that Intel's ICC (9.1) compiler runs significantly faster (30 - 50%) for some programs - this seems to stem (large) part from ICC's ability to take advantage of #pragma ivdep. There may be some other differences of course. Tests were run using gcc 3.3.3 - re-compiling relevant key code with gcc 4.1.2 did not make any real change. Wondering if there are any plans to support this ? thanks gene/ -- Summary: Support of #pragma ivdep Product: gcc Version: unknown Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: gjunk at sapience dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33427

[Bug c++/33425] GCC Compiles C++ program containing value-returning functions that don't return a value
--- Comment #2 from bobby_miesen at yahoo dot com 2007-09-13 22:21 ---
Subject: Re: GCC Compiles C++ program containing value-returning
functions that don't return a value
The reference I'm reading (The C++ Programming Language, 3rd ed., pp.
148) says in section 7.3, A value must be returned from a function that
is not declared void
...
int f1() { }// error: no value returned
So, according to a well-respected reference written by the author of
the C++ language, that statement, if I'm interpreting the meaning of
Stroustrup's comment correctly, should not be compiled by a C++
compiler. If that is true, then it should be caught by the compiler as
an error rather than a (optional) warning. But according to what you're
saying, it should only be undefined (and dangerous) behavior.
Whenever you get a chance, could you let me know where you are
getting your information from? I'd like to take a look at it myself so
we can both be on the same page.
Thanks in advance.

main.cpp: In function 'bool Func1(int)':
main.cpp:43: warning: control reaches end of non-void function
Actually in C++, this is only undefined behavior.
