[Bug gcov-profile/47618] Collecting multiple profiles and using all for PGO
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=47618 --- Comment #12 from Steven Bosscher steven at gcc dot gnu.org 2012-07-25 08:24:49 UTC --- (In reply to comment #9) I think a tool to merge would be a good partial solution. We will go with the tool solution. I'll take care of the tool before GCC 4.8, if that's OK with apinski. I think we shouldn't have a new tool, though. I'd prefer to teach the gcov program to do it instead. What would you prefer? As far as I can see what would still be missing for user-friendly usage, is a mechanism to guarantee that all pre-merged files are saved with different names, so that different processes don't overwrite each others output files. Deeply berried in the GCC manuals is this section: http://gcc.gnu.org/onlinedocs/gcc-4.7.1/gcc/Cross_002dprofiling.html With the right combination of GCOV_PREFIX_STRIP and GCOV_PREFIX, it should be possible to send the gcda files to unique directories per MPI rank. But I think that a more practical solution is necessary. (I also don't know how these environment variables interact with -profile-dir. I doubt anyone looked into this before now...) I like the %q (and %p) variables from Valgrind, and I don't think it's very hard to add support for them in libgcov. (http://valgrind.org/docs/manual/manual-core.html)

[Bug lto/54095] New: Unnecessary static variable renaming
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54095
Bug #: 54095
Summary: Unnecessary static variable renaming
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: lto
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
For example:
# cat hello.c
static int foo = 5;
extern int bar(int *);
main() {
return bar(foo);
}
# cc -flto -O hello.c -r -o hello.o -nostdlib
# nm hello.o
U bar
d foo.2353.2353
T main
There is no other symbol foo within the partition, so there's no need to
rename the static symbol within the partition.
The linux kernel modversion and CRC checking is done using static symbols
in the kernel for each exported symbol. Given that the exported symbols
must of course be unique, the kernel programmers know that the static symbols
holding the data that controls the exports must also be unique. It would
be very nice to not have to adjust the modversion logic to deal with the
renames that lto currently induces.

Especially for type-bound procedures and related features. For those, you should use the current release 4.7.1 or the developer version 4.8 You find links to unofficial gfortran builds at: http://gcc.gnu.org/wiki/GFortranBinaries (Cygwin.org does not seem to have a newer build; you might want to try the MinGW/MinGW-w64 version.)

[Bug libfortran/54097] New: configure: error: GNU Fortran is not working (CPU you selected does not support x86-64 instruction set)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54097 Bug #: 54097 Summary: configure: error: GNU Fortran is not working (CPU you selected does not support x86-64 instruction set) Classification: Unclassified Product: gcc Version: 4.5.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libfortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: pentium4b...@gmail.com Created attachment 27875 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=27875 config.log I'm trying to build a 64-bit gcc-4.3.2-r2 in a 32-bit crossdev environment on Gentoo. The CPU and host system are 64-bit. The root Gentoo system is itself a 32-bit chroot, and within this chroot I am trying to cross-compile a 64-bit environment from the 32-bit system. This has worked many times in the past, but gcc is now is failing to build. When configure for libgfortran runs, it fails with the following: configure:14588: checking whether the GNU Fortran compiler is working configure:14601: /var/tmp/portage/cross-x86_64-pc-linux-gnu/gcc-4.5.3-r2/work/build/./gcc/gfortran -B/var/tmp/portage/cross-x86_64-pc-linux-gnu/gcc-4.5.3-r2/work/build/./gcc/ -B/usr/x86_64-pc-linux-gnu/bin/ -B/usr/x86_64-pc-linux-gnu/lib/ -isystem /usr/x86_64-pc-linux-gnu/include -isystem /usr/x86_64-pc-linux-gnu/sys-include -c -O2 -march=i686 -pipe conftest.f 5 f951: error: CPU you selected does not support x86-64 instruction set configure:14601: $? = 1 configure: failed program was: | | program foo | real, parameter :: bar = sin (12.34 / 2.5) | end program foo configure:14605: result: no configure:14607: error: GNU Fortran is not working; please report a bug in http://gcc.gnu.org/bugzilla, attaching /var/tmp/portage/cross-x86_64-pc-linux-gnu/gcc-4.5.3-r2/work/build/x86_64-pc-linux-gnu/libgfortran/config.log If I copy the command and test program, and run it with -m32, that test program compiles fine. Since the target arch is i686, why does the compiler have to deliberately be told to generate 32-bit code? Is there a fix for gcc's configure or Makefiles? (Full config.log is attached.) Thanks!

Why is that? I thought -march=i686 was supposed to produce i686 compatible code (i.e., 32-bit).

Why is that? I thought -march=i686 was supposed to produce i686 compatible code (i.e., 32-bit). Because you have it set for the target libraries too which is incorrect in this case as you are creating a 64bit target library.

Fortunately the code is very similar to the 64-bit gpr secondary reload code.
