[Bug middle-end/4210] should not warning with dead code
--- Comment #17 from mattias at virtutech dot se 2006-03-02 09:22 --- We have resorted to case-by-case workarounds, usually a cast which would have been an identity operation had the condition been true. That is, if (sizeof x == 8) return x << 32 | x; would have its second line mutated to return (unsigned long long)x << 32 | x; The cast is always a no-op unless it occurs in dead code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=4210
[Bug target/26511] Using -O3, doesn't assign in a pointer to a global structure
--- Comment #3 from wielemak at science dot uva dot nl 2006-03-02 09:24 --- Andrew, If you think this is a real and still present bug I could try to add a little main() to the file and turn the file into a stand-alone program. I guess it is pretty likely it depends on nasty details in the structure definitions and it will be a lot of work to cut down the headers and still be able to compile the program and reproduce the bug. If you simply want to reproduce, fetch pl-5.6.6.tar.gz from http://gollem.science.uva.nl/cgi-bin/nph-download/SWI-Prolog/pl-5.6.6.tar.gz Unpack, goto pl-5.6.6/src, type ./configure, add -g to COFLAGS in Makefile, make (few warnings, these are fixed already but do not affect this problem), abort Prolog which will be crashing in a loop using ^\. Now gdb pl (gdb) break initPrologThreads (gdb) run (gdb) finish (gdb) print *info And you see the problem. The nasty thing is that if you add a print-statement reading the info->pl_tid, it is compiled correctly. It gives the impression that somehow gcc thinks the value is never used and it thus can ignore the assignment. As the structure is in global memory (part of the threads[] array) and it *is* used, this is of course completely wrong. Cheers --- Jan -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26511

--- Comment #2 from pcarlini at suse dot de 2006-03-02 10:24 --- Benjamin, can you have a look? The issue seems simple, in its essence: on 64-bit machines the recently added __copy_streambufs export is wrong - in fact we are not exporting anything - because it reads everywhere: _ZSt17__copy_streambufsI[cw]St11char_traitsI[cw]EEiPSt15basic_streambuf* and should be, on 64-bit machines, note l, not i, after the EE: _ZSt17__copy_streambufsI[cw]St11char_traitsI[cw]EElPSt15basic_streambuf* The only problem now is doing the right thing wrt the library abi, i.e., I'm not sure we can simply adjust now the export @GLIBCXX_3.4.6... -- pcarlini at suse dot de changed: What|Removed |Added CC||bkoz at redhat dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26526

--- Comment #4 from pluto at agmk dot net 2006-03-02 14:32 --- http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/24592.pdf page 33: [ Zero-Extension of 32-Bit Results. ] (...) when performing 32-bit operations with a GPR destination in 64-bit mode, the processor zero-extends the 32-bit result into the full 64-bit destination. 8-bit and 16-bit operations on GPRs preserve all unwritten upper bits of the destination GPR. This is consistent with legacy 16-bit and 32-bit semantics for partial-width results. Software should explicitly sign-extend the results of 8-bit, 16- bit, and 32-bit operations to the full 64-bit width before using the results in 64-bit address calculations. -- pluto at agmk dot net changed: What|Removed |Added CC||pluto at agmk dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26457

template

}
=== END PRE-PROCESSOR OUTPUT ===
It seems to be triggered when the type is parameterized on at least two types.
Removing the MYMACRO({...}) wrapping makes it compile. Putting just about
anything except certain template heavy stuff inside it also compiles.
(The above is obviously a contrived example to trigger the issue; my real usage
is a macro for critical sections with guaranteed mutex cleanup.)

This is not a bug.
There are two arguments passed to the macro MYMACRO, "{\nSomeClass test;\n }".
the only way to force an argument passed to the preprocessor macros is to wrap
them in parentheses.

I see I still missed something: the rules for finding the assembler and linker used by the installed compiler. It seems that the rules to find these utilities are different when building than when using the compiler. When building gcc, it looks for them in PATH. When using gcc, it considers system directories first. Btw., is there a way to switch between the native and GNU assembler and linker without rebuilding the compiler? It seems that 4.1 with the GNU utilities is a lot slower than 4.0.2 was when using the native ones (I wasn't actually using the GNU utilities with 4.0.2 despite what I said before). Martin

[Bug tree-optimization/14703] Inadequate optimization of inline templated functions
--- Comment #6 from eric-gcc at omnifarious dot org 2006-03-02 20:25 --- I'm pleased that I came up with such a difficult test case for the optimizer. I never thought it'd be that hard. :-) I don't know anything about the internals, but... The compiler has to generate everything down to the fibconst<0> and fibconst<1> specializations anyway. So why can't it memoize and filter the optimization up? Say it generates fibconst<1> and fibconst<2> in order to generate fibconst<3>, then it discovers that fibconst<3> can be optimized to return plain old '3'. It can save that, and then when it comes down again needing fibconst<2> and fibconst<3> in order to generate fibconst<4>, it can see the already optimized version of fibconst<3> and generate an optimized version of fibconst<4> that just returns plain old '5'. Maybe I have things totally wrong and there's no way to do anything like that with the code. Or maybe it would turn out that that way of doing things is so special case that it's not worth bothering with. But, I just wonder if memoizing some sort of optimized version of a function would help with a lot of things. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14703

--- Comment #8 from roger at eyesopen dot com 2006-03-02 21:39 --- I think I've found the problem. On mainline, its in tree-scalar-evolution.c at around line 1652, where where handle NEGATE_EXPR in interpret_rhs_modify_expr. The code checks whether the type is SCALAR_FLOAT_TYPE_P, in which case it uses build_real, otherwise it calls build_int_cst_type. Unfortunately, with a complex type, we end up generating a (const_int (complex4) -1) which is very broken. I believe a suitable fix would be to replace this logic with something like fold_convert (type, integer_minus_one_node), which will produce the correct result for integers, reals and complex numbers. My change to fold-const.c just has stricter error checking and refuses to fold operations of mismatched types, and return NULL_TREE instead. It wasn't a fix, it just hid the problem which is still present but latent on mainline. I think. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26524

No this should not compile and here is why:
class Rational {
public:
Rational& negate() { return *this; }
};
namespace pm {
Rational& inv_sign(Rational& x) { return x.negate(); }
}
Rational is in the toplevel namespace so that is the only place where argument
dependent lookup will look to find the function inv_sign. Argument dependent
lookup will not relook into the namespace pm.

This code:
extern char *nl_langinfo (int) __attribute__ ((__nothrow__));
char *
xtermEnvEncoding(void)
{
static char *result;
if (result == 0)
result = nl_langinfo(50);
return result;
}
gets compile by gcc-4.1.0 -march=i686 -mtune=i686 to:
xtermEnvEncoding:
[snip]
.L6:
movl$50, (%esp)
callnl_langinfo
movl%eax, result.1281
movlresult.1281, %eax < note this
leave
ret
Note the redundant mov instruction. 4.0 does not generate that extra
instruction.
The extra instruction seems to be generated by the bbro pass. Here is the RTL
dump for the .44.rnreg pass: nothing unusual
(call_insn:HI 17 16 19 1 (set (reg:SI 0 ax)
(call (mem:QI (symbol_ref:SI ("nl_langinfo") [flags 0x41]
) [0 S1 A8])

(nil))
(nil))
(insn:HI 19 17 20 1 (set (mem/f/c/i:SI (symbol_ref:SI ("result.1281") [flags

(reg:SI 0 ax [orig:58 D.1283 ] [58])) 34 {*movsi_1}
(insn_list:REG_DEP_TRUE 18 (nil
))
(expr_list:REG_DEAD (reg:SI 0 ax [orig:58 D.1283 ] [58])
(nil)))
but the next dump, .45.bbro shows that an extra move instruction has been
inserted.
(call_insn:HI 17 16 19 2 (set (reg:SI 0 ax)
(call (mem:QI (symbol_ref:SI ("nl_langinfo") [flags 0x41]
) [0 S1 A8])
(const_int 4 [0x4]))) 531 {*call_value_0} (nil)
(expr_list:REG_EH_REGION (const_int 0 [0x0])
(nil))
(nil))
(insn:HI 19 17 54 2 (set (mem/f/c/i:SI (symbol_ref:SI ("result.1281") [flags
0x2] ) [2 result+0 S4 A32])
(reg:SI 0 ax [orig:58 D.1283 ] [58])) 34 {*movsi_1}
(insn_list:REG_DEP_TRUE 18 (nil

(expr_list:REG_DEAD (reg:SI 0 ax [orig:58 D.1283 ] [58])
