[Bug debug/48333] -fcompare-debug failure (length) - memmove x __builtin_memmove
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48333 --- Comment #3 from Alexandre Oliva aoliva at gcc dot gnu.org 2011-03-31 06:12:22 UTC --- Created attachment 23832 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=23832 Patch that fixes the bug It's a garbage collection issue: we're supposed to share mem_attrs involving __builtin and non-__builtin functions, and we do, unless GC manages to discard mem_attrs at precisely the worst possible moment, and does so at only one of the compilations, and we're unlucky to end up inserting a different one next time it is required. A more general solution would amount to checking for builtins at dump time, and discarding the __builtin prefix or noting it as optional or somesuch, but I'm testing this simpler and hopefully effective solution instead.
[Bug libstdc++/48382] New: ctype_noninline.h should not be installed
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48382 Summary: ctype_noninline.h should not be installed Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: i...@airs.com Currently libstdc++-v3 installs the header file ctype_noninline.h. No other header file #include's it. The comment after the license boilerplate says This is an internal header file, included by other library headers. Do not attempt to use it directly. The header file exists to be included by src/ctype.cc. I think that in include/Makefile.am ctype_nonline.h should move from host_headers to host_headers_noinst.

[Bug preprocessor/48383] New: Line continuations handled incorrectly in 4.5 and above
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48383 Summary: Line continuations handled incorrectly in 4.5 and above Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: preprocessor AssignedTo: unassig...@gcc.gnu.org ReportedBy: d...@cowlark.com Given the following test file: foo \ bar ...then if I preprocess it with gcc 4.4 (using gcc -E), I get this: foo bar ...but if I preprocess it with gcc 4.5 or 4.6, I get this: foo bar This would appear to me to violate 5.1.1.2.1.2 of the C99 draft, which states: Each instance of a backslash character (\) immediately followed by a new-line character is deleted, splicing physical source lines to form logical source lines. Given that the following test file: foo\ bar ...always preprocesses to this: foobar ...then I suspect that what we've got here is an optimisation to keep line number information correct on the 'bar' token; the reasoning would presumably be that since C (and C++) treats newlines like all other whitespace, it makes no difference whether the 'bar' token is on the same line or a new line. Unfortunately, I believe the spec doesn't allow this behaviour. (This is actually biting us because we're using cpp to preprocess files before passing them to a perl script, and are relying on cpp to glue line continuations together. As of gcc 4.5, this is no longer happening.)

The rules of C++ say that B b( A() ) is interpreted as a declaration of a function called b which takes a single parameter and returns B ... and as the error says, you cannot declare a static variable at function scope. To declare a static variable you need to do: static B b = B( A() ); or static B b = A();

Ditto for Fortran, if ptr is not a POINTER but a normal variable. In case of Fortran, the a/b/c cannot alias with ptr as none of has the TARGET attribute. I would expect the same for C99 as a/b/c are restrict but maybe I am wrong about the C99 semantics.

OS: Windows 7 64-bit Compiler: MinGW gcc 4.5.2-tdm1 32-bit As shown in the attachment, the shared_ptr usage in the first part of the main function will cause excessive system memory consumption (which will not show in process' memory usage). While the second part of the main function, calling a multi-threaded task in conjunction with the shared_ptr's memory problem, will actually cause the OS to throw an exception to abort the program in just a dozen of seconds. In this short example I'm pretty sure something is wrong with tr1/memory's shared_ptr. If you changed to boost/tr1/memory.hpp (and please don't specify BOOST_HAS_TR1_SHARED_PTR), all codes executed and finished without any problem.

For example, this crashes: @try { @throw [[OFObject alloc] init]; } @catch (id e) { [e release]; } Trying to printf(%p, …) the exception before the throw and in the catch shows that the pointer differs, which should not happen. I had this bug in various GCC versions from 4.2 up to 4.6. I suspect even earlier versions are affected.

Allocno a10r80 of GENERAL_REGS(6) has 5 avail. regs obj 0 0-5 (confl regs = 6-51 ) node: 0-5, obj 1 0-5 (confl regs = 6-51 ) node: 0-5 ... Popping a7(r74,l0) -- assign reg 2 ..

Than function improve_allocation decides that spilling r74 and assigning hard reg to r84 is more profitable. The function at the end of its work was trying to assign another hard reg to r74 and assign C reg again which is wrong because of r80 needs two hard registers DX and CX. The wrong assignment is because of wrong code in function (assign_hard_reg) searching conflicting hard regs. The code deciding that conflicting allocnos really conflicts looks like hard_regno = ALLOCNO_HARD_REGNO (conflict_a); if (hard_regno = 0 ira_class_hard_reg_index[aclass][hard_regno] = 0) where aclass is class of r84 (CREGS) and hard_regno is r80 hard regno (DX). This code was ok for cover classes. It should be different when different classes of allocnos can intersect. I'll send a patch to solve the PR soon.
