Reason: islower 2 ISLOWER 0 toupper A TOUPPER a

[Bug fortran/45505] [4.6 Regression] gfortran.dg/pr25923.f90
--- Comment #4 from jakub at gcc dot gnu dot org 2010-09-07 08:05 ---
This isn't specific to Fortran,
struct S { int a; };
struct S foo (struct S *arg)
{
struct S s;
if (bar ())
baz (not valid);
else
s = *arg;
return s;
}
has the exactly same difference.
I believe this is caused by ESRA or gimplification. In *.ealias we have:
bb 5:
[pr25923.f90 : 22:0] D.1570 = res;
return D.1570;
and in *.esra this is:
bb 5:
# res$yr_9 = PHI res$yr_8(D)(3), [pr25923.f90 : 20:0] res$yr_3(4)
[pr25923.f90 : 22:0] SR.2_10 = res$yr_9;
D.1570.yr = SR.2_10;
return D.1570;
Note no locus on D.1570.yr = SR.2_10; assignment. The question is if ESRA just
forgots to set the locus, or if it sets it from the following stmt
(GIMPLE_RETURN). If the former, then it would just be a SRA bug, if the
latter,
then the question is why don't we set location on GIMPLE_RETURN.
Note that on the C testcase there apparently is locus on GIMPLE_RETURN between
gimplification and gimple lowering (where the locus on it is lost).
On the Fortran testcase in *.gimple the locus is strange:
[pr25923.f90 : 22:0] D.1570 = res;
[pr25923.f90 : 13:0] return D.1570;
Line 22 is the END FUNCTION line, line 13 is the FUNCTION line. For C it is
obvious where it wants to report the return, for Fortran, given that it doesn't
have any kind of RETURN statement, I guess either of the locations is fine, but
we should be consistent.

[Bug middle-end/45579] New: Re-enable IPA-CP for fn spec
Follow up to PR 43665. Both fn spec (a TYPE_ATTRIBUTES) and -fipa-cp are important optimization features. However, -fipa-cp can eliminate arguments and does not update fn spec, leading to wrong code. Thus, ipa-cp has been disabled if it encounters an attribute, cf. PR 43665 's attachment 21714. Expected (missed optimization): ipa-cp updates fn spec to account for the eliminated arguments. fn spec allows to annotate to aid optimization via: /* Nonzero if the argument is not dereferenced recursively, thus only directly reachable memory is read or written. */ #define EAF_DIRECT(1 0) /* Nonzero if memory reached by the argument is not clobbered. */ #define EAF_NOCLOBBER (1 1) /* Nonzero if the argument does not escape. */ #define EAF_NOESCAPE (1 2) /* Nonzero if the argument is not used by the function. */ #define EAF_UNUSED(1 3) And IPA-cp does a complementary optimization: -fipa-cp Perform interprocedural constant propagation. This optimization analyzes the program to determine when values passed to functions are constants and then optimizes accordingly. This optimization can substantially increase performance if the application has constants passed to functions. This flag is enabled by default at -O2, -Os and -O3. -- Summary: Re-enable IPA-CP for fn spec Product: gcc Version: 4.6.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: enhancement Priority: P3 Component: middle-end AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: burnus at gcc dot gnu dot org BugsThisDependsOn: 43665 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45579

[Bug tree-optimization/45580] New: [4.6 Regression] Building WebKit fails with compiler catching SIGSEGV in gimple_fold_obj_type_ref_known_binfo()
When building JSGlobalObject.cpp from webkit's source with GCC rev.163944 the compiler ICEs in gimple_fold_obj_type_ref_known_binfo() because it attempts to execute fndecl = TREE_VALUE (v) with v equal to NULL. The preprocessed source is quite big, but I've got no knowledge of webkit's internals and can't reduce it in reasonable time. GCC was configured with the following options: ../gcc-current/configure --prefix=/home/artem/testing/gcc46 --enable-shared --enable-bootstrap --enable-languages=c,c++ --enable-threads=posix --enable-checking=release --with-system-zlib --disable-libunwind-exceptions --enable-__cxa_atexit --enable-libssp --with-gnu-ld --with-lto --disable-nls --verbose --with-arch=athlon64 --target=x86_64-slackware-linux --build=x86_64-slackware-linux --host=x86_64-slackware-linux --disable-multilib --enable-checking=release --enable-stage1-languages=c,c++ and then built with make STAGE1_CFLAGS=-g -O0 all-stage1. To reproduce, do cc1plus -dH -O1 JSGlobalData.i JSGlobalData.o. It's important to run compiler on 64-bit host because preprocessed JSGlobalData assumes that sizeof(double)==sizeof(long int). -- Summary: [4.6 Regression] Building WebKit fails with compiler catching SIGSEGV in gimple_fold_obj_type_ref_known_binfo() Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: aanisimov at inbox dot ru GCC build triplet: x86_64-slackware-linux GCC host triplet: x86_64-slackware-linux GCC target triplet: x86_64-slackware-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45580

--- Comment #5 from matz at gcc dot gnu dot org 2010-09-07 13:42 --- Since Ira implemented unaligned support in SLP mode we get somewhat further, but not much. If complete unrolling is active that we can't disambiguate between *s and *(s+stride). That is correct because stride is unknown and might be 8. The problem is the code generated by unrolling looks like so: b_1[0] = s1_2[0]... b_1[1] = s1_2[1]... ... b_3 = b_1 + 8; s1_4 = s1_2 + stride; b_3[0] = s1_4[0]... b_3[1] = s1_4[1]... Now SLP checks for dependencies between the first block of access and those in the second block. Although this is really uninteresting for SLP, nevertheless it prevents SLPing here because the dependencies can't be computed. Deactivating loop-unrolling reveals another problem, namely that SLP doesn't support multiple types at all, see vect_build_slp_tree. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43434

[Bug tree-optimization/33244] Missed opportunities for vectorization due to PRE
--- Comment #2 from matz at gcc dot gnu dot org 2010-09-07 14:41 --- Since the fix for PR44710 we can if-convert the conditions in the inner loop. With http://gcc.gnu.org/ml/gcc-patches/2010-09/msg00542.html we also make sure that the latch block isn't filled, which in turn then triggers the if-conversion. This then reveals the rest of the problems, which are: * inlining needs to happen (our default parameters don't inline ginteg) The patch above ensures this by making the functions internal * a library with vectorized logf needs to be available (libacml_mv for instance) The patch above works around this by getting rid of calls to log/sqrt * loop interchange needs to happen, because in the original testcase we have: do i=0,Ng1 do j=0,Ng2 G(i,j) = ... exactly the wrong way around. Our loop-interchange code is only capable of vectorizing perfect nests, which here doesn't exist as LIM and PRE move out some loop invariant expressions from the inner to the outer loop. If we weren't doing that, that itself would already prevent vectorization. The patch above works around this by doing the interchange by hand. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33244

I installed the latest native binutils and gcc-4.5.1 on my linux installation. The script now works without any errors. However it appears that using the supplied binutils and compilers from Ubuntu 10.04 there is a problem creating the cross compilers. I do not know how or if I should proceed from here. It maybe there there is some subtle error in the bins supplied with Ubuntu. Thank You, Donald Schlicht I've just read this thread and am now unsure as to whether there is a bug with GCC or not.

[Bug target/44557] internal compiler error: in gen_thumb_movhi_clobber, at config/arm/arm.md:5811
--- Comment #5 from ibolton at gcc dot gnu dot org 2010-09-07 16:24 ---
(In reply to comment #4)
I my earlier tests I failed to notice that this test case triggers one of two
different ICEs, depending on options and compiler version. I also mistakenly
tested with a locally modified gcc-4.4.
The ICE in this PR, in gen_thumb_movhi_clobber, is triggered by r147270 +
r147274, updates to loop-invariant.c part of PR33928 fixes with no ARM
specific
bits. Another ICE, in default_secondary_reload, is triggered by r146904.
Which ICE you get depends on -f{no-,}forward-propagate. Both ICEs disappear
if
r146904 is reverted. gcc-4.4.4 includes a backport or r146904 and does
trigger
the default_secondary_reload ICE. gcc-4.3.4 does not ICE.
I can't get this to ICE with latest version of 4.4, 4.5 or 4.6 branches.
I am doing:
arm-none-linux-gnueabi/obj/gcc3/gcc/cc1 -O1 -mthumb -fno-omit-frame-pointer
pr44557.i
Please can someone else try to see if they can still get the ICE.

[Bug libstdc++/45574] ifstream::getline() is extremely slow
--- Comment #4 from tstarling at wikimedia dot org 2010-09-07 17:18 --- Benchmarking on Solaris indicates that cin.getline() takes only 1us per iteration there, but I don't think the source code is available, so it's hard to provide details. However, I think that a huge speedup could be achieved by making basic_istreamchar::getline() into a simple wrapper around a GNU-specific virtual function in basic_streambuf. This would allow it to be specialised in stdio_sync_filebuf, where it could be implemented using fgets() or getdelim() instead of getc(). This would have the additional positive impact of making it atomic. Currently, cin.getline() does not properly lock the underlying libc stream with flockfile(). This means that if one thread is calling cin.getline(), and another thread is calling getc(), then cin.getline() may return mangled partial lines due to interleaved calls to getc() from the other thread. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45574
