[Bug tree-optimization/51005] -ftree-tail-merge slows down compilation of 20001226-1.c
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51005 --- Comment #4 from vries at gcc dot gnu.org 2011-11-14 12:05:58 UTC --- Created attachment 25816 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=25816 Patch that also delegates updating the vops, but keeps dominator info up-to-date bootstrapped and reg-tested on x64_64 and i686, build and reg-tested on ARM and MIPS (with an additional verify_dominators after each update). This patch updates dominator info after each cluster application. It does this roughly in the following way: - for a cluster, determine the nearest-common-dominator dom - for the dom, determine the set directly dominated by the dom, called fix_dom_bbs - for each of fix_dom_bbs, determine whether there is a path from dom to it, which does not pass through cluster. If for a member of fix_dom_bb such a path exists, it is still directly dominated by dom. If such a path doesn't exist, it's now dominated by cluster. The patch implement this path search by a walk marking all bbs reachable from dom but not through cluster. This walk is done once for each cluster. For the example, there are 2 clusters of 4096 bbs in 1 iteration. Using this patch, the compilation time for this example is comparable to recalculating the dominator info each iteration from scratch. The time-complexity of this approach per iteration is O(n_clusters * (n_bbs + n_edges)). Best case, this algorithm is faster than recomputing dominator info from scratch each iteration. But worst case, it's slower.

[Bug c++/51121] New: Duplicate destructors

Bug #: 51121
Summary: Duplicate destructors
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: d...@mm.st
g++ generates bad assembly for this code:
---
#include decimal/decimal
#include map
#include string
using std::decimal::decimal32;
int
main( int, char ** )
{
std::multimap decimal32, std::pair std::string, decimal32m;
decimal32 d1;
std::string str;
decimal32 d2;
m.insert( std::make_pair( d1, std::make_pair( str, d2 )));
return 0;
}
---
Specifically, it says
$ g++ -c multimap_decimal.cpp
/tmp/cc2sQism.s: Assembler messages:
/tmp/cc2sQism.s:1690: Error: symbol `_ZNSt4pairIDfS_ISsDfEED2Ev' is already
defined
That symbol is the destructor for std::pair decimal32, std::pair std::string,
decimal32 . It seems that g++ is instatiating a destructor for that type
and with the first decimal32 replaced with const decimal32 and giving both the
same mangled name. So it works if I change the m.insert() line to
std::pair const decimal32, std::pair std::string, decimal32
p( d1, std::make_pair( str, d2 ));
m.insert( p );
.ii file attached.
$ g++ -v

[Bug other/50925] [4.7 Regression][avr] ICE at spill_failure, at reload1.c:2118
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50925 --- Comment #8 from Jeffrey A. Law law at redhat dot com 2011-11-14 17:09:04 UTC --- I'm not going to be able to look at it anytime soon, but just some general thoughts: 1. Disabling caller-saves probably isn't appropriate. Just looking at codesize isn't the way to evaluate caller-saves either as caller-saves is tasked with improving performance, possibly at the expense of codesize. 2. The first thing someone needs to do is provide information as to why that insn needs reloads. I don't know enough about the AVR to hazard as guess why that insn needs reloads. 3. Find out where insn 172 comes from. There are restrictions on the insns created by caller-save. So if caller-save creates a bogus insn, then that needs to be investigated. Anyway, that's where I'd start. I can't say enough that disabling caller-saves merely to work around this problem is wrong wrong wrong.

Call add_method for using declarations that designates functions if the using declaration is in a template class. Set DECL_IGNORED_P on class-scope using declarations. * typeck.c (build_class_member_access_expr): Handle USING_DECLs. * class.c (check_field_decls): Keep using declarations.

[Bug c/51129] New: 4.7 trunk libgcc cannot compute suffix of object files - cannot find find libcloog, though in path
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51129
Bug #: 51129
Summary: 4.7 trunk libgcc cannot compute suffix of object files
- cannot find find libcloog, though in path
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: c
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: ohsu...@molbio.mgh.harvard.edu
I am trying to compile the trunk version of gcc (checked out around 2:30 PM
Eastern Nov. 14, 2011) under SuSE linux using gcc 4.1.2 20070115 (default
installed). I have cloog-ppl-0.15.11, gmp-5.0.2, mpc-0.9, and mpfr-3.1.0 all
installed in /usr/local/{include,lib} and have m4-1.4.16 in /usr/bin. All of
the libraries passed their checks before I installed them. I have
declare -x LDFLAGS=-L/usr/local/lib -L/usr/local/lib64 -L/usr/lib -L/usr/lib64
-L/lib -L/lib64
-R/usr/local/lib:/usr/local/lib64:/usr/lib:/usr/lib64:/lib:/lib64
declare -x
LD_LIBRARY_PATH=/usr/lib:/usr/lib64:/lib:/lib64:/usr/local/lib:/usr/local/lib64
Now in the below, directories /tools and /store1/tools are identical. I then
did
sudo /tools/gcc-4.7.0_src/configure --enable-langugages=c,c++,fortran
--prefix=/tools/gcc-4.7.0 --with-gmp-include=/usr/local/include
--with-gmp-lib=/usr/local/lib --with-mpc-include=/usr/local/include

--with-ppl-lib=/usr/local/lib --with-cloog-include=/usr/local/include
--with-cloog-lib=/usr/local/lib
in directory /tools/gcc-4.7.0_build followed by sudo make -j6. (I also tried
it without the -j6. Same problem.) It compiles xgcc in subdirectory gcc
successfully. However, then the build crashes on

What is puzzling is that

lrwxrwxrwx 1 root root 17 2011-11-14 13:58 /usr/local/lib/libcloog.so.0 -

-rwxr-xr-x 1 root root 428100 2011-11-14 13:57 /usr/local/lib/libcloog.so.0.0.0
the library is there and the path is in both LD_LIBRARY_PATH as well as
LDFLAGS. Furthermore, I specified the path to cloog in the configure options.
(I even tried doing a soft-link to /usr/lib, but with no success.) Any
thoughts on why this is occurring?
I would be grateful for any information regarding how to resolve this.

The following line: __H_n = 2 * (__x * __H_nm1 + (__i - 1) * __H_nm2); should be changed to: __H_n = 2 * (__x * __H_nm1 - (__i - 1) * __H_nm2); I have attached a patch (generated inside poly_hermite.tcc's folder) which makes this change. This patch has been tested with gcc 4.6.1 by checking via numerical integration that the resultant polynomial has the correct orthogonality. As implemented, the result of this numerical integration was extremely accurate to at least 14 decimal places at up to n=84 for double precision.

[Bug c/51129] 4.7 trunk libgcc cannot compute suffix of object files - cannot find find libcloog, though in path

[Bug bootstrap/51098] [4.7 Regression] bootstrap failed on avx i686, svn revision 181259 to 181267
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51098 --- Comment #5 from Richard Henderson rth at gcc dot gnu.org 2011-11-14 23:50:59 UTC --- ... which will not be declared if AVX support is disavowed. ... except that the configure was --with-arch=corei7-avx. If true, the problem is user error. How can you expect to configure for corei7-avx without a working avx assembler? Otherwise, we've mis-identified the assembler support and this is a configure bug. Only the reporter can tell us which of these alternatives hold. --- I suppose we could change the configure check to be #ifndef __AVX__ asm (vzeroupper); #endif assuming that if --with-arch/CFLAGS says avx is present, believe it. Let this fail later (again as user error) if the assembler can't actually assemble AVX insns.
