IS IT A BUG ????
Hi, The following is the program to print magic squares.I`m getting wierd output when i remove the printf statement printf(a) from the code. The required output is obtained by simply substituting that by putchar('\0'). I would be very glad if someone can let me know. Please kindly help me regarding this. Expecting an early rep, Srujan.K.V.S //This is a simple program to design magic squares. //A magic square is an arangment of numbers of numbers from 1 to n^2 such // that any row, diagonal or column sums to the same.

[Bug tree-optimization/22488] [4.1 Regression] push_fields_onto_fieldstack calculates offset incorrectly
--- Additional Comments From mmitchel at gcc dot gnu dot org 2005-09-28 15:57 --- If so, are those fields of A in B really *there*, at those offsets from the beginning of type B? Sort of. Because B would otherwise need a virtual table pointer, it just uses the one in A. So, there is a vptr at offset zero from the start of B. However, there's no actual A object at the same address as B because A is a virtual base. There's certainly no A::i at offset four from the start of B, for example. The layout you had posted in the bug matches the offsets when we process the type A field of C, but not the type A field of type B. Ugh. We create two versions of class types: the complete class type and the as-base type. (Look for CLASSTYPE_AS_BASE.) The as-base type does not include virtual bases, and the B field in C should have the B-as-base type, not the complete B type. The B-as-base type does not have the A parts. In fact, if you look at layout_class_type, and, in particular, build_base_field, you'll see it does use the as-base type. However, at the end of layout_class_type, we have: /* Now that we're done with layout, give the base fields the real types. */ and that installs the complete type. Jason added this in 2004: + 2004-04-30 Jason Merrill [EMAIL PROTECTED] + + Refer to base members using COMPONENT_REFs where possible. + * class.c (build_simple_base_path): New fn. + (build_base_path): Use it for non-virtual base references. + (layout_class_type): Change base fields to their real type + after layout is done. I think this is a hack so that later, when we use the COMPONENT_REFs, we don't have to cast from the as-base type back to the nominal C++ type. (Of course, this would also be cleaner with a real C++-lowering pass.) However, I think the right thing is to have the cast; as you've discovered, Jason's approach is lying about what's really there.

[Bug c/24106] New: x86_64 -fPIC code gen bug (extern/static linkage confusion)
With this testcase: int foo (int (*cb)(void)) { return (*cb)(); } static int callback(void) { return 0; } int main (void) { int callback (void); return foo (callback); } On x86_64 with -fPIC, the address of callback as passed to foo is incorrect. If callback isn't static, it works (through the GOT). If the declaration of callback is removed it works (computes the address as %rip minus something). As written, it does a failed combination of the two. The result is that instead of passing callback's address, it loads the first 8 bytes at callback's address and passes those. (It also erroneously claims callback is unused, but I'm guessing that's a side-effect.) The code is questionable, but my reading of the standard says it's legal and that callback is still static after the (implicitly extern) declaration. % gcc-3.4.4 -O2 -fPIC -Wall -save-temps -o bug bug.c bug.c:2: warning: 'callback' defined but not used % gcc-3.4.4 -v Reading specs from /usr/local/lib/gcc/x86_64-pc-linux-gnu/3.4.4/specs Configured with: /tmp/src/gcc-3.4.4/configure --enable-languages=c,c++ --enable-version-specific-runtime-libs --disable-shared --enable-threads --with-gnu-as --with-gnu-ld --with-pic --host=x86_64-pc-linux-gnu Thread model: posix gcc version 3.4.4 [I bootstrapped this 3.4.4; it also fails with stock 3.4.3 from RedHat.] -- Summary: x86_64 -fPIC code gen bug (extern/static linkage confusion) Product: gcc Version: 3.4.4 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mcoiley at yahoo dot com CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: x86_64-pc-linux-gnu GCC host triplet: x86_64-pc-linux-gnu GCC target triplet: x86_64-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24106

Daniel agreed that the problem is in his code. No, it actually isn't. I sent mark a followup mail, that didn't get put into the bug report for some reason. The type looks like this: Main type of var: C First field of C: field of type B ( field_decl 0x40212ebc D.1814 type record_type 0x40212170 B ... chain field_decl 0x40212b24 x) First field of B : _vptr.B ( field_decl 0x40212450 _vptr.B ... chain type_decl 0x401eec98) Second field of B: type_decl ( type_decl 0x401eec98 B ... chain field_decl 0x40212564 D.1781) Third field of B: field of type A ( field_decl 0x40212564 D.1781 ... chain NULL) Second field of C: field of type X (field_decl 0x40212b24 x type record_type 0x4020e844 X ... chain type_decl 0x401eee38 C) Third field of C: type_decl (type_decl 0x401eee38 C ... chain field_decl 0x4021605c D.1817) Fourth field of C: field of type A (field_decl 0x4021605c D.1817 type record_type 0x4020e9b4 A .. chain NULL) This causes us to walk type A twice (once as the third field of B, once as the fourth field of C), and where we get the offsets wrong, since we process the fields of type A twice. I don't see why type A appears in type C except through type B Is this because of virtual inheritance? If so, are those fields of A in B really *there*, at those offsets from the beginning of type B? The layout you had posted in the bug matches the offsets when we process the type A field of C, but not the type A field of type B. IE type A appears in two places. It's the first place that screws us up. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22488

Our code sequence doesn't look a lot worse than the sequence generated by icc 9.0, at first glance. We could try something like: if %ecx 31: mov %eax, %ebx shldl $31, %edx, %eax shldl $31, %ebx, %edx %ecx -= 31 if %ecx 31: mov %eax, %ebx shldl $31, %edx, %eax shldl $31, %ebx, %edx %ecx -= 31 if %ecx != 0: mov %eax, %ebx shldl %cl, %edx, %eax shldl %cl, %ebx, %edx but, that doesn't seem clearly better than what we presently generate. * f2 uses the roll instruction, which appears optimal. * f3 uses two shdl instructions, which appears optimal. * f4 uses the rorl instruction, which appears optimal. For all of f2 and f3, it looks like we generate code better than you get with icc 9.0.
