[Bug fortran/35831] Type-mismatch check missing for dummy procedure argument
--- Comment #5 from burnus at gcc dot gnu dot org 2008-04-11 07:45 --- If on the other hand Tobias is right in the assumption he made in comment #3, then one could something along the lines of if (f1-sym-as-type != f2-sym-as-type) I would not be surprised if foo(*) and foo(4) are allowed and then your test rejects too much. My feeling is that at least the array size should match for explicit-shape arrays, I'm not sure about that part; one can create valid (i.e. working) programs which violate this (e.g.: array(5), array(10), but only accessing 1 to 5). We should check what the standard says about this. I think it is formally invalid to do so; if we decide to allow it, at least a warning should be printed. (At the end one needs to carefully read the standard, unfortunately, I do not have much time the next two, three weeks. One could also ask at comp.lang.fortran.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35831

[Bug target/35907] New: [4.3/4.4 Regression] 64-bit power6 glibc miscompilation
build_trtable function from posix/regex.c is miscompiled on ppc64-linux with -mcpu=power6. The $v31 register is used within the function and is therefore saved in prologue and restored in epilogue, but as the function uses alloca, it is restored from different memory slot than it was saved into. Options used: -fpreprocessed -quiet -m64 -mcpu=power6 -mno-minimal-toc -mnew-mnemonics -mlong-double-128 -g -O3 -std=gnu99 -fgnu89-inline -fasynchronous-unwind-tables -fmerge-all-constants -fpic The interesting lines in the assembly are: .build_trtable: ... li 0,320 ... stdu 1,-496(1) stvx 31,1,0 mfvrsave 0 mr 31,1 ... ld 0,0(1) ... stdu 0,-12304(1) ... li 0,320 lvx 31,1,0 ld 1,0(1) ... blr The above is with the trunk gcc, but 4.3 is similar. Unlike this, gcc 4.1 saved the vector register early: li 0,-176 stvx 31,1,0 as first two insns in the routine, before first stdu, and restored after incrementing stack pointer back: ld 1,0(1) mr 3,0 li 0,-176 lwz 12,-148(1) lvx 31,1,0 So, with 4.1.x this works, but with 4.3/trunk $v31 will get the value of a memory slot 12304 bytes (i.e. the size of alloca) below where it was actually saved. -- Summary: [4.3/4.4 Regression] 64-bit power6 glibc miscompilation Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jakub at gcc dot gnu dot org GCC target triplet: powerpc64-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35907

[Bug c/35885] unsigned long long and while loop evaluation regression?
--- Comment #3 from wilson at tuliptree dot org 2008-04-12 00:45 --- Subject: Re: New: unsinged long long and while loop evaluation regression? I can reproduce this on a 32-bit x86-linux machine (i.e. a 32-bit HWI). The unsigned long long 0x becomes a (const_double -1 0), and then in expand_mult in expmed.c we have /* If we are multiplying in DImode, it may still be a win to try to work with shifts and adds. */ if (CONST_DOUBLE_HIGH (op1) == 0) coeff = CONST_DOUBLE_LOW (op1); After this line, expand_mult thinks we are multiplying by -1 and we get the wrong result. I think there is a false assumption here that we can get CONST_DOUBLEs which can be simplified to a single word. Maybe in the olden days we always created a CONST_DOUBLE for DImode constants? This stuff has changed so many times it is hard to remember. I don't think we do it that way anymore. Anyways, if this assumption is not false, then the code needs to look more like the code in immed_double_const in emit-rtl.c, which does /* If this integer fits in one word, return a CONST_INT. */ if ((i1 == 0 i0 = 0) || (i1 == ~0 i0 0)) return GEN_INT (i0); where i1 is CONST_DOUBLE_HIGH and i0 is CONST_DOUBLE_LOW, and only in the case that this tests succeeds can we set coeff to CONST_DOUBLE_LOW. The same bug is in mainline, and probably goes a long ways back. Jim -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35885

[Bug c/35908] Dubious charset conversions
--- Comment #2 from neil at daikokuya dot co dot uk 2008-04-12 04:40 --- Subject: Re: Dubious charset conversions joseph at codesourcery dot com wrote:- GCC accepts the following with -ansi -pedantic -Wall without diagnostics #include stdlib.h wchar_t z[] = La \xff; GCC claims a default execution charset of UTF-8; presumably the default execution wide character set is UTF-32. But \xff is a two-character narrow execution character set string literal, with characters \xff \0, which is invalid UTF-8 and so cannot be converted in a meaningful way to the execution character set (whatever it is). I would expect the above code to be rejected, or at least diagnosed. Accepting it as equivalent to La\xff (generating a wide character L'a' followed by one with value 0xff) seems in accordance with the principles of N951, the relevant ones of which are implemented in GCC. http://www.open-std.org/jtc1/sc22/wg14/www/docs/n951.htm http://gcc.gnu.org/ml/gcc-patches/2003-07/msg00532.html Ah, I'd forgotten about that. That document does make much more sense, thanks. However I think there are at least two things wrong in Principle 7; I've mailed Clive about those. [The single byte requirement cannot be fulfilled for Latin source charset to UTF-8 target, for example, and UCNs are escape sequences that typically cannot be encoded as a single byte]. GCC should perhaps consider not creating invalid UTF-8 (i.e. no 5 or 6 bytes forms, or encodings of \ufffe \u etc.) Please feel free to close this report.
