John Marino bc7ac57a74 lang/gcc-aux: Upgrade from gcc-4.7.3 to gcc49-20140302 snapshot ... GCC4.9 hasn't been released yet, but the Ada portion of it is pretty stable and perfectly passes ACATS and gnat.dg testsuites. The only trick was to change the unwind mechanism on i386 away from KERN_PS_STRINGS because it will not work with 32-bit compatability mode on AMD64. This is because on AMD64, the signal trampoline is located on a random area on a shared page rather than a fixed location before KERN_PS_STRINGS. To support both true i386 and AMD64-32 compatibility mode, unwind now looks for frame pattern in all cases. Apparently stack checking has been broken on AMD64-32 until now. It is important to get the Ada Framework in ports to be based on gcc49 because this compiler supports the full Ada-2012 standard implementation, and in fact some new programs require this already. This port will stay on snapshots until 4.9.0 is released, then it will return to be based on releases. The Ada and C++ options have been removed. These are now always built. In fact, GCC now requires C++ to build, so new bootstraps had to be created. FreeBSD8 has its own bootstrap, and FreeBSD 9+ uses a pure static bootstrap (including GNAT tools) which should last a long time. Additionally a "Bootstrap" option was added, but this overrides all other options to create new bootstraps. It is not intended for general use. Most of the Ada Framework in ports has been pretested and adjusted to work with gcc49 out of the box, but some ports will need to be updated immediately, which will happen right after this one. The update to lang/gnat_util had to be synchronized with lang/gcc-aux because they share version information and the PORTREVISION needed to be reset.		2014-03-14 08:36:05 +00:00
