[Bug other/47029] New: fixincludes: the fix for c99 inlines in the glibc header files fixes function declarations as well as function definitions
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47029 Summary: fixincludes: the fix for c99 inlines in the glibc header files fixes function declarations as well as function definitions Product: gcc Version: 4.4.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other AssignedTo: unassig...@gcc.gnu.org ReportedBy: hkodungal...@gmail.com I am building gcc version 4.4.2 on centos 32-bit machine. # uname -a Linux rh55-i386 2.6.18-194.el5PAE #1 SMP Fri Apr 2 15:37:44 EDT 2010 i686 i686 i386 GNU/Linux The build is successful. But my project fails to build using this built gcc. The error (actually warning; we have -Werror set) is: /opt/gcc-4.4.2/bin/../lib/gcc/i686-pc-linux-gnu/4.4.2/include-fixed/sys/stat.h:317: warning: inline function ‘lstat64’ declared but never defined /opt/gcc-4.4.2/bin/../lib/gcc/i686-pc-linux-gnu/4.4.2/include-fixed/sys/stat.h:286: warning: inline function ‘fstatat64’ declared but never defined /opt/gcc-4.4.2/bin/../lib/gcc/i686-pc-linux-gnu/4.4.2/include-fixed/sys/stat.h:255: warning: inline function ‘fstat64’ declared but never defined /opt/gcc-4.4.2/bin/../lib/gcc/i686-pc-linux-gnu/4.4.2/include-fixed/sys/stat.h:250: warning: inline function ‘stat64’ declared but never defined The version of glibc on the system is: # rpm -q glibc glibc-2.5-49 It looks like fixincludes 'fixes' the function declarations as well, converting them to extern inline. Example: this one from sys/stat.h: #ifndef __USE_FILE_OFFSET64 /* Get file attributes for FILE and put them in BUF. */ extern int stat (__const char *__restrict __file, struct stat *__restrict __buf) __THROW __nonnull ((1, 2)); gets converted to the following in the includes-fixed/sys/stat.h: #ifndef __USE_FILE_OFFSET64 /* Get file attributes for FILE and put them in BUF. */ #ifdef __GNUC_GNU_INLINE__ extern #endif __inline__ int stat (__const char *__restrict __file, struct stat *__restrict __buf) __THROW __nonnull ((1, 2)); Similar thing for all the stat/lstat/fstat and stat64/lstat64/fstat64 functions. The fixincludes should fix only the function definitions. Although I've marked it as in Version 4.4.2, apparently this bug is present in the latest code.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47000 --- Comment #26 from Jan Hubicka hubicka at gcc dot gnu.org 2010-12-21 10:39:42 UTC --- Hi, I read the comment only after comiting the patch. We generally believe conversions to be free even if this is not always the case. FP-int conversions tends to be expensive, too. I don't think it is serious problem since the conversions tends to be dominated by real work elsewhere and there is good chance for conversions to combine and optimize when code is duplicated by inlining or peeling or so. For non-registers V_C_Es are already counted as all non-register accesses are believed to be read/writes. So all we get wrong are those int-fp V_C_Es. I don't think they are terribly common and it is very target specific on how expensive they really are... SSE intrincics and SRA are nowdays both quite good source of V_C_Es that are cheap so I would guess that wast majority of them is cheap anyway. Honza

Accessors are used all the time, having a kernel lock each time will be a giant slowdown, especially as most of the time, the lock is not held anyway and if it is, it's only held for a very short period of time. I think this should be changed to spinlocks, even for 4.6. Should I create a bug report for that? If the problem is that we don't know whether we have a spinlock implementation on the system and would need to patch configure.ac and this is too much change before the release, we could just use gcc's __sync_bool_compare_and_swap, spin 10 times and if we still could not acquire our spinlock give control to another process using yield().

We can make the change for 4.6 if we make it safe. By the way, changing configure.ac is not a problem, we can do that, particularly if it makes the change safer. ;-) It could make the change safer - we could check that spinlocks are available, and use them if so; if not, we just fall back to using a standard mutex, which is slower but works on all platforms.

Actually, we need to recheck the DFA after M cycles again. I will submit the patch tomorrow after further testing and I can commit it either until Friday or next January, so Zdenek, please let me know if there are further problems with this patch.

Can you try the trunk? Yes, looks like this bug is fixed in trunk. Assembly output looks sane. I will see if it works on real hardware some time later today. Do you know svn revision it got fixed? No but the change was done by Iain Sandoe to fix enum TLS with LTO on darwin. The fix to emuTLS on trunk is from Richard Henderson's new implementation. http://gcc.gnu.org/viewcvs?root=gccview=revrev=162549 I made some fixes to LTO-compatibility and Section anchors, but they primarily affect ObjC* and PPC-darwin, so likely not relevant to your case.

my patch doesn't help in these cases (which clang does warn about):
A() : a(this-a) { }
A() : a((int)a) { }
A() : a(a+1) { }
For that we need proper tracking of uninitialized variables, which we don't do
for member variables. But my patch catches the simple typo where you
accidentally use the wrong variable name in a mem-initializer.

This just adds noise to the testsuite reports, so the xfails need to be
adjusted.

I have no way to test an extension to non-darwin platforms nor commit rights,

[Bug fortran/47034] New: TRANSFER of C_PTR: Components of structure constructor are PRIVATE
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47034 Summary: TRANSFER of C_PTR: Components of structure constructor are PRIVATE Product: gcc Version: 4.6.0 Status: UNCONFIRMED Keywords: rejects-valid Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: bur...@gcc.gnu.org http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/05c3648efda0dc9b# - and especially http://groups.google.com/group/comp.lang.fortran/msg/7e9e61c22a76f683 James Van Buskirk reports that use ISO_C_BINDING type(C_PTR), parameter :: p1 = transfer(32512_C_INTPTR_T,C_NULL_PTR) integer(C_INTPTR_T), parameter :: n1 = transfer(p1,0_C_INTPTR_T) fails with: integer(C_INTPTR_T), parameter :: n1 = transfer(p1,0_C_INTPTR_T) 1 Error: Components of structure constructor 'c_ptr' at (1) are PRIVATE The error is questionable as the first line works w/o error - and as there is no structure constructor involved at all. While the internals are private, TRANSFER usually does not care about this.
