gcc 4.6.0 was released on March 25\, 2011

It would be embarrassing if perl 5.14.0 didn't build and pass tests on it.

From @dgl

I had a go at setting up a smoker using gcc 4.6.0 (basically by using arch's testing repo). That passed fine with -O3\, apart from some new compiler warnings (see results attached).

I then thought I'd try link time optimisation\, that didn't go so well\, basically it seems the try.c program written by Configure gets optimised to the extent that the symbol it uses disappears (see output below).

I wonder if it would be worth having support in Configure for not running the 'try' programs with optimisations on (maybe via hints?)?

PS: This feels more like a known issue than a 5.14.0 blocker to me.

PS: This feels more like a known issue than a 5.14.0 blocker to me.

Yes\, me too.

I've fixed the compile time warnings that are easy to fix in the branch nicholas/gcc460.

Some of the others will be harder as they're variables within macros\, and similar. Given that this means radically changing the call parameters of these macros\, I think ideally that we'd also replace them with inline functions as part of the change\, given that we now have infrastructure to do that.

As far as I can tell [ie just gcc 4.6.0 and 4.3.2 :-)] removing the dead source code has *no* effect on the object files generated\, from which I infer that the optimiser already recognises the code as worthless\, and so eliminates it.

Given that we can't eliminate all these warnings right now\, and as long as gcc 4.6.0 is *just* producing warnings (not failures) [need more platform testing]\, I think it best to document the warnings as a harmless known issue\, and resolve the problem in 5.15

gcc 4.6.0 was released on March 25\, 2011

It would be embarrassing if perl 5.14.0 didn't build and pass tests on it.

Seems to build and pass all tests on x86 and x86_64 Linux\, albeit with warnings.

It won't build on OS X without patching\, something like this:

Otherwise the compiler fails with an error, something like this:

$ echo | gcc-mp-4.6 -no-cpp-precomp -E - gcc-mp-4.6: error: unrecognized option '-no-cpp-precomp' $ echo $? 1

It was only a warning with gcc 4.5 from macports:

$ echo | gcc-mp-4.5 -no-cpp-precomp -E - gcc-mp-4.5: unrecognized option '-no-cpp-precomp' # 1 "\" # 1 "\<built-in>" # 1 "\<command-line>" # 1 "\" $ echo $? 0

I'm not sure if this is the right thing to apply.

[Note\, much to my pleasant surprise\, macports builds gcc-4.6 in about an hour on my 3 year old laptop. gcc-4.5 takes 3 hours (swaptastic)\, and gcc-4.4 about 2.5. So it's not insane to install it to try it out. Currently the 4.6 is actually still a snapshot\, albeit very recent\, not the real thing :-(]

Patch to hv.c and pp_sys.c to fix some variable-set-but-not-used

It happened that I'd already committed fixes for them to my branch nicholas/gcc460 as 9029c9aff9243ad7 and 3d6ff8202f9280ca

(with analysis in the commit message for 9029c9aff9243ad7 about how the problem arose)

Patch to cflags.SH to suppress unused-but-set-variable warning

I think that\, long term\, having warning is useful\, and something we should work on cleaning up. Meanwhile\, short term\, this close to 5.14\, I'd feel more comfortable leaving code unchanged\, and documenting the warnings as a "known issue". (But it's Jesse's call)

Hey folks\,

Nick has recently (I believe) integrated the patches needed to get Perl building and passing tests on GCC 4.6.0\, but we could really use smoking across a range of platforms.

I'd like to see GCC 4.6.0 smoke reports for (at least):

Linux x86 Linux x86_64 OSX x86_64 OSX PPC Something on SPARC Something else.

Anybody who can contribute one of those gets a gold star.

Thanks!

I'm currently building on SPARC to try gcc-4.6.0 with Solaris 8. 5 hours into the build\, and the gcc build is up to stage 2. (At least this is better than the last time I tried with gcc-4.5.something\, where it died building one of the pre-requisite libraries.) If the build succeeds\, I'm hopeful that over the weekend I'll be able to try building perl with it.

I'm also hoping to get to fixing the Ubuntu library bug.

Whilst the above works\, I was wondering\, how general are Configure's Call Back Units? Is it possible to manipulate lddlflags in a CBU after the C compiler has been chosen? Or is the above the only real way to do it?

(The head commit of the branch tonyc/gcc460)

Whilst the above works\, I was wondering\, how general are Configure's Call Back Units? Is it possible to manipulate lddlflags in a CBU after the C compiler has been chosen? Or is the above the only real way to do it?

They are inconsistently and only occasionally implemented (i.e. not all metaconfig units have them) \, but when available they are completely general -- they are simply sourced with something like

. ./cc.cbu

In this case\, putting that stuff in a cc.cbu call-back unit should work. (The chances of a user picking a different compiler later are also rather slim\, however\, so leaving it as it is there probably would usually work too.)

I'll have a fiddle with that today.

Replaced tonyc/gcc460 with the cbu version of the change.

Configured/built/tested with gcc 4.6.0 and the system cc.

Hey folks\,

Nick has recently (I believe) integrated the patches needed to get Perl building and passing tests on GCC 4.6.0\, but we could really use smoking across a range of platforms.

I'd like to see GCC 4.6.0 smoke reports for (at least):

Linux x86 Linux x86_64 OSX x86_64 OSX PPC Something on SPARC

I'm currently building on SPARC to try gcc-4.6.0 with Solaris 8.

Good news: I had no new problems on Solaris 8/SPARC with gcc-4.6.0.
(There are a couple of test quirks I'm pursuing that I think have to do with an old bzip2 and symlinks\, perhaps complicated by clock skew and NFS.
Certainly nothing related to gcc-4.6.0.)

Anybody who can contribute one of those gets a gold star.

My $WORK Fedora 14 Linux x86_64 machine using Fedora 15 gcc 4.6.0 packages had no issues that aren't already present. g++ and gcc reports are attached because my hastily-copied smoking environment apparently failed on the delivery part.

On my laptop I found that I could build gcc 4.6 in one hour\, whereas gcc 4.5 took 3. Their release notes at http://gcc.gnu.org/gcc-4.6/changes.html say:

Compile time and memory usage improvements

Datastructures used by the dataflow framework in GCC were reorganized for better memory usage and more cache locality. Compile time is improved especially on units with large functions (possibly resulting from a lot of inlining) not fitting into the processor cache. The compile time of the GCC C compiler binary with link-time optimization went down by over 10% (benchmarked on x86-64 target).

and that seems to have paid off nicely\, in my case because my machine is avoiding swap hell at various points in the build.

With Tony's fixes for NetBSD and GCC 4.6 today\, I'm declaring this one resolved unless we hear otherwise about GCC 4.6 on some common platform.

gcc 4.6.0 was released on March 25\, 2011

It would be embarrassing if perl 5.14.0 didn't build and pass tests on it.

Seems to build and pass all tests on x86 and x86_64 Linux\, albeit with warnings.

It won't build on OS X without patching\, something like this:

Looks good to me.

I also suggest ld=$cc
