[Bug middle-end/27116] [4.2 Regression] Incorrect integer division (wrong sign).
--- Comment #17 from vincent at vinc17 dot org 2006-06-08 07:18 --- The patch looks strange to me too: is there any reason why the optimization would be correct under wrapping? i.e. I don't understand why -fwrapv can "fix" the problem (as said in comment #1). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27116

[Bug c++/27955] New: friend members produce different results
I've encoutered a problem with a friend function embedded into a class declaration AND with the optimisation flag -O2. I have discovered that two successive identical call to cout< class A{ friend void load (A* a, float& t){ reinterpret_cast(t) = 1077936128; //binary float value of 3 } }; class B{ friend void load (B* b, float& t); }; void load (B* b, float& t) { reinterpret_cast(t) = 1077936128; //binary float value of 3 } int main(){ float testValue = -1; //OK load(new A(), testValue); std::cout

--- Comment #13 from sje at cup dot hp dot com 2006-06-08 15:11 --- The proposed patch does fix the compilation time problem on hppa64-hp-hpux11.11 but I am confused about how the cache works. Without the patch, the compile takes 15 to 20 minutes but I do wind up generating a sequence of instructions instead of a call to __divdi3. With the patch, I get a very fast compilation, but I also get a call to __divdi3 instead of the code sequence. Why does caching results change the behaviour? Caches (in general) should speed things up by saving previous/intermediate results, but shouldn't change the ultimate answer.

The we fill the cache with the algorithm for say 0x10085 (but then we only write 0x84 in the cache), and then use it for 0x85. The synth_mult logic then could be resilient enough to not generate wrong code but just code with wrong cost measures. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27733

I'm not terribly familiar with the code in question or this PR. But it seems to me that negating a signed type's minimum value should give you the same value with an overflow. ie, for a 32bit signed type - (-2147483648) => -2147483648 If I read your proposed change, you'd instead return the type's max value, in this case 2147483647.

Output lines on Windows are incorrectly terminated. Example: program le integer i do i = 1,6 print *, 'Line ', i end do end The output looks ok on the windows console. However, if you redirect output to a file, and examine with a hexadecimal viewer, you will see that each line is terminated by CR/CR/LF, instead of CR/LF which would be correct for Windows.

I fear this is the wrong way round: it shouldn't be necessary to unbreak the affected targets one by one, but boehm-gc should only be included in noconfigdirs if it is known not to work (which is what noconfigdirs is for).

This local variable is only created on systems that pass structures by pointers and which are callee copied. I think this variable should be a local stack variable but I think that is what we have now. Then we run into the gcc_assert in make_decl_rtl, if I just comment out that assert I run into one in expand_expr_real_1. It may be that the function context is not set when creating this temporary, that would explain the expand_expr_real_1 assert. -- sje at cup dot hp dot com changed: What|Removed |Added CC||sje at cup dot hp dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26957
