This is a bug fix release, the final of the GCC 4.6 series.
The official change page is http://gcc.gnu.org/gcc-4.6/changes.html
According to it, 86 bugs have been resolved since version 4.6.3 was
released (2 P1 bugs, 20 P2 bugs).
GCC 4.6.3 was released 01 MAR 2012. It is a bug-fix release for regressions
and serious bugs. Seventy-four bug reports were addressed. The link is
available at bottom of http://gcc.gnu.org/gcc-4.6/changes.html
Unlike release 4.6.2, a few Ada issues were among those addressed.
Previously the Ada testsuite was given unlimited stack resources for the
x86_64 arch on NetBSD. Since all platforms now need unlimited stack
resources to build gnat-aux due to the addition of <platform>-stdint.h
header, this platform specific restriction on the Ada testsuite was
removed.
Unfortunately that resulted in a new stack test failure on i386 NetBSD
platforms (gnat.dg/task_stack_align.adb execution test), so the original
restriction seen in gnat-aux-20110627 was restored. Now i386 NetBSD
once again pass all gnat.dg tests. This is strictly a testsuite issue
so no PKGREVISION bump is necessary.
Obvious additions:
1) Upgrades sync from gcc 4.6.1-RELEASE to gcc 4.6.2-RELEASE
2) New capability of building Fortran
3) New capability of building Objective-C
4) Building of all 5 languages (Ada,C,C++,ObjC,Fortran) now default
5) Fortran testsuite added
6) ObjC testsuite added
Behind the scenes:
1) Previously GNAT-Aux was built from a custom-built tarball. Now real
real gcc source files are used instead, but heavily patched.
2) The standard patch mechanism is not used. Composite diff files are
generated by dragonlace.net and they are applied as needed, and
are located in the "files" directory
3) This might be the only gcc that doesn't use the monolithic source tar
ball. Depending on the options selected, the makefile updates its
distfile list and only downloads what it needs, including testsuite
files and dejagnu support.
4) All platforms are now built with unlimited stacksize command due to
new issues with <platform>-stdint.h functionality.
5) All platforms use unlimited stacksize for Ada testing. Before it was
limited to NetBSD x86_64. This may have introduced a failure on
NetBSD i386 though. There were no other impacts according to the
Ada testsuite results.
6) The PLIST automatic generation was significantly simplified, resulting
in some variable deletion.
7) libstdc++ can't break testing now (forced to evaluate to true)
8) Unnecessary depends and USE_TOOLS removed
9) The includes-fixed directory is now removed from all platforms, arches
now rather than problematic ones. It seems that it can only make no
difference or cause problems, so no reason to keep it around.
A) Unnecessary do-config phase "touches" removed.
B) Several fixes added to diff patches to improve testsuite results on
c, c++, and fortran for all platforms.
The GNAT compiler project builder essentially doesn't support DESTDIR
out of the box. By default, it sets rpath of shared libraries to the
directory to which they are installed. One may add additional rpaths
through switches, but not remove these default ones. Also added to
the default rpath are the paths to the ada library and the standard
localbase library.
This modification to the compiler will force the project builder to
recognize the -R switch (gnatlink uses this to disable rpaths), and
it reacts by not putting the library install path into rpath. The
adalib and ${LOCALBASE}/lib paths will still make up the base rpath
definition of the built shared libraries.
This change was prompted by the rpath troubles of the XML/Ada package.
This changeset addresses several things:
1) Adds support for x86-Solaris (Namely OpenIndiana)
2) Properly implements run-time symbolic traceback support
3) Arranges makefile so patches can be handled in a standard fashion
4) Properly implements MAKE_JOBS which reduces build times by 66%+ on
the quad-core test machine (30 minutes down to < 10 minutes)
John Marino per PM
-deal with possibly builtin gmp/mpfr/mpc libs (this is incomplete
for D'fly -- choices are to convert the pre-configure test or
to set USE_BUILTIN.x=no)
changes:
-newer gcc snapshot
-add option to build c++ support (not enabled per default because
the build fails due to something which looks like a command line
length limitation on NetBSD)
John Marino, originally per PR pkg/44436, slightly updated
for i386/amd64, comes with a bootstrap which doesn't need an Ada compiler
on the pkg build system (fetches a bootstrap binary from MASTER_SITE)
There seems to be some incompatibility with the binutils/libgcc_s
on NetBSD-current, leading to warnings. Not fatal, but should be
investigated.
