[Bug c++/14912] Do not print default template arguments in error messages
--- Additional Comments From giovannibajo at libero dot it 2005-03-23 10:51 --- The first non-trivial issue is that, in order to print "std::vector" instead of "std::vector >", we need to do the template substitution at error printing time, and check if the resulting substitution match. Either that, or I need to mark template arguments with a flag if they come from the template-id. Also, should we skip default arguments also in lines like this: test.cc: In member function `void A::foo() [with T = int, int N = 0, int X = 1]': We would be left with something like : test.cc: In member function `void A::foo() [with T = int]': I assume that sounds about right, even if it might be surprising at first why the "with" clause does not show all the parameters. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14912

Yet PRE decides to use 0x601, so the

[Bug c++/14912] Do not print default template arguments in error messages
--- Additional Comments From dave at boost-consulting dot com 2005-03-23 12:55 --- Doesn't sound right to me. I think you should either show vector or include A in the "with" clause of vector. I'm sort of inclined to the former; Don't forget that parameter names are not always so short. Another related issue is that "with" clauses are sometimes unhelpful, as in the case you cite. vector is much, much clearer. GCC ought to have a heuristic based on the lengths of the version with the "with" clause and the version with a full argument substitution, to decide whether to use "with" or just substitute the arguments in-line. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14912

[Bug c++/20589] error: '' is/uses anonymous type'
--- Additional Comments From bangerth at dealii dot org 2005-03-23 18:53 --- Intuitively, C++ treats unnamed enums differently than named ones, because in templates the function/class name has to be mangled, and will contain the name of the template arguments. If the template argument doesn't have a name, then the compiler can't do its job, so the standard chose to disallow unnamed enums as template arguments. For more legalese, this is specified in section 14.3.1/2 of the standard, which says: 2 A local type, a type with no linkage, an unnamed type or a type compounded from any of these types shall not be used as a template- argument for a template type-parameter.

[Bug c++/20607] New: -fstrict-aliasing causes incorrect scheduling on Sparc Solaris
On Sparc Solaris, the attached code leads to the following assembly sequence being produced at the beginning of a function. Stack slot %fp-32 is read before it is written. Turning off either -fstrict-aliasing or -fsched-insns causes the problem to go away. I'm relying on the GCC extension that allows type punning via unions, and assuming a big endian layout of all the datatypes. As specified by the -fstrict-aliasing documentation, I'm copying the value out of the union rather than taking an address of a union member. 0: 9d e3 bf 80 save %sp, -128, %sp 4: d6 07 bf e4 ld [ %fp + -28 ], %o3 8: c2 07 bf e0 ld [ %fp + -32 ], %g1 c: c2 27 bf e8 st %g1, [ %fp + -24 ] 10: 19 00 00 20 sethi %hi(0x8000), %o4 14: 1b 3f ff ff sethi %hi(0xfc00), %o5 18: 9a 13 63 ff or %o5, 0x3ff, %o5 ! 1c: d8 3f bf e0 std %o4, [ %fp + -32 ] g++-3_4_3 -v -save-temps -O1 -c -o u64solrs.o u64solrs.c -fschedule-insns -fstrict-aliasing Reading specs from /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.3/specs Configured with: ./configure --prefix=/arm/eda/tools/gnu/gcc/3_4_3 --exec-prefix=/arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc --program-suffix=-3_4_3 --enable-languages=c,c++ -v --with-dwarf2 --enable-version-specific-runtime-libs --with-gnu-as --with-as=/arm/eda/tools/gnu/binutils/2_15/solaris_2_9-sparc/bin/as-2_15 --with-gnu-ld --with-ld=/arm/eda/tools/gnu/binutils/2_15/solaris_2_9-sparc/bin/ld-2_15 Thread model: posix gcc version 3.4.3 /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/libexec/gcc/sparc-sun-solaris2.9/3.4.3/cc1plus -E -quiet -v u64solrs.c -mcpu=v7 -fschedule-insns -fstrict-aliasing -O1 -o u64solrs.ii ignoring nonexistent directory "/arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.3/../../../../sparc-sun-solaris2.9/include" #include "..." search starts here: #include <...> search starts here: /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.3/include/c++ /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.3/include/c++/sparc-sun-solaris2.9 /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.3/include/c++/backward /usr/local/include /arm/eda/tools/gnu/gcc/3_4_3/include /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/lib/gcc/sparc-sun-solaris2.9/3.4.3/include /usr/include End of search list. /arm/eda/tools/gnu/gcc/3_4_3/solaris_2_9-sparc/libexec/gcc/sparc-sun-solaris2.9/3.4.3/cc1plus -fpreprocessed u64solrs.ii -quiet -dumpbase u64solrs.c -mcpu=v7 -auxbase-strip u64solrs.o -O1 -version -fschedule-insns -fstrict-aliasing -o u64solrs.s GNU C++ version 3.4.3 (sparc-sun-solaris2.9) compiled by GNU C version 3.4.3.

It's swapped out of my brain, but there was another PR, and I did raise the issue for Steve Adamczyk, to be added to the core issue list. The basic point is that the SFINAE rules simply do not cover this case; they precisely describe a set of situations in which no error should be issued, and trying to use an anonymous type as a template parameter is not among them. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20589

Hmm, we are dying because of the following instruction:
(jump_insn 169 168 170 19 (set (pc)
(reg/f:DI 66 [ #ref#6#19 ])) 515 {*indirect_jump_rtx64} (nil)
(expr_list:REG_DEAD (reg/f:DI 66 [ #ref#6#19 ])
(nil)))
But that does not make sense since this is a computed goto.
Why is computed_jump_p (insn) not returning true?

(In reply to comment #2)
> Why is computed_jump_p (insn) not returning true?
Actually it is the following insn:
(jump_insn 169 222 170 19 (set (pc)
(reg:DI 0 ax)) 515 {*indirect_jump_rtx64} (nil)
(insn_list:REG_LABEL 172 (nil)))
Which is a computed goto but at this point we have a REG_LABEL which causes
computed_jump_p to
return false.

Hmm, I think this is a reload or a recognizing problem.
inside reload (when adding the LABEL_REG), we have the following instruction:
(jump_insn 169 222 170 19 (set (pc)
(label_ref:DI 172)) 515 {*indirect_jump_rtx64} (nil)
(expr_list:REG_DEAD (reg/f:DI 66 [ #ref#6#19 ])
(nil)))
But this is not an indirect_jump_rtx64 at this point but instead just a jump.
I cannot debug it further than this sorry.

[Bug c/20609] New: install-sh not found
I keep getting a "install-sh not found" when trying to install gcc on a Solaris 9 box. The problem is when there is no compatible BSD install program in the current path, configure defaults to using install-sh supplied in the top level dir of the src. However either configure or the Makefile it generates is not setting the relative path to install-sh in the Makefiles of the subdirectories. The work around is to either install a BSD compatible install program like ginstall and make sure the binary is in your current path. Or to uncompress the gcc source, run configure as normal, then edit the top level Makefile and set INSTALL to the absolute path of install-sh. -- Summary: install-sh not found Product: gcc Version: 3.4.3 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: hip at cs dot okstate dot edu CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20609

[Bug middle-end/20610] New: Real by complex multiplications perform unnecessary operations
When doing real by complex multiplications in C++ using std::complex,
the multiplication is transformed to a complex by complex multiplication, even
though the imaginary part is zero for one of the arguments.
This is similar to TR 19953, however there is still a problem even though it is
supposed to be fixed.
Here is a small test program:
#include
std::complex a, b;
double c;
void f()
{
a = b * c;
}
When compiled with "g++ -O3 -march=pentium4 -mfpmath=sse -S -c test.C", the
following is produced (from test.s):
_Z1fv:
.LFB1857:
pushl %ebp
.LCFI0:
movl %esp, %ebp

gcc and as bug
I have encountered what seems to be an error of unforgiving nature when
attempting to compile a device driver for the parallel port. I also
attempted to compile the example given in Riku Saikkonen's HOW TO on I/O
port programming using options 0-6 with the same result.
The error is centered on the use of inb and outb (macros I understand)
in my C program (and Saikkonen's). When removed it compiles.
The error is: Error: suffix or operands invalid for 'in' { also for 'out'}.
My configuration is: glibc=2.3.2, gcc=3.2.3, as=2.14.90.0.6 20030820,
kernel 2.4.22, vendor Slackware 9.1, motherboard=KT4V-L, CPU=AMD 2200+,
circa 1.8GHz, FSB=133 MHz.
If you could point me to the resolution, as I am sure I am not the
first, I would appreciate it as this has been ongoing for 10 days now
and are not able to find a
solution on the web.
Thanks,

[Bug target/20611] New: duplicate label for inlined function referencing TLS
PAPI fails to build on powerpc-linux with "-O3 -fPIC" due to multiple symbols of the same name in assembler output. The minimized test case demonstrates the problem. The failure occurs on the 3.4 branch (the FSF version in which TLS is first supported for powerpc-linux) and on the hammer-3.3 and 3.4-rhl branches, but not on mainline or the 4.0 branch. There is not a problem with 64-bit compilation. I'll run a regression hunt to determine when the fix was added and hope that it's something smaller than the tree-ssa merge. -- Summary: duplicate label for inlined function referencing TLS Product: gcc Version: 3.4.4 Status: UNCONFIRMED Severity: normal Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: janis at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: powerpc-linux GCC host triplet: powerpc-linux GCC target triplet: powerpc-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20611

[Bug target/20286] [3.3 only] gcc panic with __thread attribute
--- Additional Comments From wilson at gcc dot gnu dot org 2005-03-24 00:09 --- That patch that fixed this in gcc-3.4 is too large to backport, particularly when considering that it depends on other stuff (such as default_encode_section_info) which is not already present in gcc-3.3. However, it can be fixed with a simpler patch. The underlying problem is that a variable changes state from TLS_MODEL_INTIAL_EXEC (extern) to TLS_MODEL_LOCAL_EXEC (static). This is an allowable transition. This unfortunately triggers an abort in the ia64.c backend in ia64_encode_section_info. The comment next to the abort makes it clear that this is checking for transitions between thread data and small data. So the fix is to tighten the conditions under which we call the abort to match the conditions documented in the comments. The same INITIAL_EXEC to LOCAL_EXEC transition happens in gcc-3.4, there just isn't a corresponding abort in default_encode_section_info. Technically, this isn't a regression, as gcc-3.2 did not have TLS support, and gcc-3.3 is only open for regression fixes, so there is the question of whether this patch is OK to install on the branch. A strict interpretation of the rules says this is not OK, at least not without approval of the branch maintainer, Gaby. -- What|Removed |Added AssignedTo|unassigned at gcc dot gnu |wilson at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2005-03-02 16:48:16 |2005-03-24 00:09:55 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20286

Note the problem shows up in .31.bbro which duplicates the BBs. This must likely can be shown still on the mainline/4.0 branch but it is harder to find an example where we do. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20611
