[patch] pr 21302 Max line length in free form mode
Hi,
Attached proposed patch would close pr 21302 for me.
Is reusing -ffixed-line-length instead of introducing a new
-fline-length ok?
If it isn't, should -ffixed-line-length be renamed to -fline-length
and -ffixed-line-length be an alias for the new -fline-length?
thank you,
Bernhard

[Bug libstdc++/23271] Members of ctype_base appear not to be integral constant expressions.
--- Additional Comments From john at johnmaddock dot co dot uk 2005-08-08 09:57 --- Is the print member really already overflowed? It has a value of 0200 which is 0x80: so if char is signed (it is on cygwin) then it's setting the sign bit, which should be OK I think. Although I admit I would have prefered the use of an unsigned type as a bitmask. Aha! Is this the cause? : the signed value is promoted to an int initially *with sign extension*, and then when the compiler has all the values it desides that the enum needs only one byte for storage, so it tries to fit all the values into "signed char", and only then finds that the promoted value won't fit? I'm just making wild guesses here you understand! Thanks, John Maddock. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23271

[Bug inline-asm/22045] can't find a register in class 'GENERAL_REGS'
--- Additional Comments From macro at linux-mips dot org 2005-08-08 17:42 --- Richard, Thanks for your work (for bug 21291). Unfortunately it's not enough for this case. It doesn't seem to work for the "g" constraint used there, but that might probably be considered just a shortcoming -- "=rm" or "rmi" can be used instead as appropriate. But more importantly it doesn't work with an early clobber and that's something that cannot be avoided -- GCC has to be told that a register, if used, is to be destroyed early. To summarize, the case does not work as is -- with "=&g" and "g". It does not work with "=&rm" and "g". It does work with "=rm" and "g", but it's dangerous as GCC will probably allocate both the same register. It does work with "=m" and "g", but it sort of misses the point. I removed the "register" keyword from the affected variables for these tests as it is problematic for the "=m" case (the keyword should be safe to be removed from glibc now, as it requires at least GCC 3.2 these days). Please let me know if that's clear enough. Or whether I should reopen the other (duplicate) bug rather than this one. -- What|Removed |Added Status|RESOLVED|REOPENED Resolution|DUPLICATE | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22045

[Bug c++/23287] New: Explicitly invoking destructor of template class
When explicitly invoking a template class destructor the compiler outputs a
compile-time error message, "expected class-name before '(' token."
NOTE: Same code compiles on 'gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)'

If you've got some other test case that runs out of registers, then its some other problem and wants its own PR. You'll need a new test case.

Confirmed, for some reason the following is caught though:
unsigned short f(unsigned short a)
{
unsigned short b = a <<1;
if (a & 0x8000)
a <<= 1, a = a ^ 0x1021;
else
a = b;
return a;
}
as a<<1 is caught being redundant. FRE catches the above on the mainline.
Hmm there is only one VH for the expression:

Created value VH.2 for VH.0 << 1
Created value VH.3 for VH.2 ^ 4129

This is not a missed optimization for PRE. PRE is not a generic hoister. In fact, in this case, it doesn't actually save anything but size to perform this "optimization". All it will do is make b live over the use of a, adding another register to allocate that has a conflict. I don't see this as a bug at all, except maybe at -Os.

It produces the following output:
# ./testpackage
ClassLoader: [EMAIL PROTECTED]
Package: null
This is tested with libgcj 3.4.3, however Tom Tromey has proven this still exist
in latest HEAD (as of 2005-08-08):

[Bug rtl-optimization/23289] New: tail call optimization not performed
Compiling:
typedef unsigned int Cardinal;
typedef char *String;
typedef struct _WidgetRec *Widget;
typedef union _XEvent {
int type;
long pad[24];
} XEvent;
extern int SendMousePosition (Widget w, XEvent* event);
void
HandleIgnore(Widget w,
XEvent * event,
String * params ,
Cardinal *param_count )
{
(void) SendMousePosition(w, event);
}
with 4.0 and 4.1 -march=i686 -O2 generates: (the sdiff is shown)

Note that 4.1 does not generate a jump to SendMousePosition, but a call.
This is one of the reasons for the code size regression in PR23153.

> Confirmed, for some reason the following is caught though:
If you thought about it, you'd notice that your example below has two
computations of a = b along the if branch, which is not optimal.
The original has one computation on each path which is already optimal.

[Bug libgcj/23288] java.lang.Class's #getPackage() returns null
--- Additional Comments From pinskia at gcc dot gnu dot org 2005-08-08

Confirmed:
It works when interpreting the byte-code:
earth:~>gij men.gcjpackage.TestPackage
ClassLoader: gnu.gcj.runtime.SystemClassLoader{urls=[file:./],
parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
Package: package men.gcjpackage
But not when natively:
earth:~>!./a
./a.out
ClassLoader: gnu.gcj.runtime.SystemClassLoader{urls=[file:./],
parent=gnu.gcj.runtime.ExtensionClassLoader{urls=[], parent=null}}
Package: null
