===================================================================
2013-08-22 Magnus Granberg <zo...@gentoo.org>
* gcc/gcc.c (main): Add support for external spec file via the
GCC_SPECS env var
and move the process of the user specifed specs.
This allows us to easily control pie/ssp defaults with gcc-config
profiles.
Original patch by Rob Holland
Extended to support multiple entries separated by ':' by Kevin F. Quinn
Modified to use getenv instead of poisoned GET_ENVIRONMENT by Ryan Hill
Modified to process the GCC_SPECS env var befor DRIVER_SELF_SPECS by
Magnus Granberg

===================================================================
Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.
Solves error messages like the following:
msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1:
version `GCC_4.2.0' not found (required by
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
The libgcc_s.so used during build doesn't satisfy the needs of the
libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
is used as a stand-alone application here, and what library it uses
behind the scenes is of no concern to the gcc build process.
Therefore, simply invoking it "as usual", i.e. without any special
library path, will make it work as expected here.

we also provide -mno-ieee.

===================================================================
The gcc-3.x toolchains would contain all the targets by default. With gcc-4,
you have to actually list out the multilibs you want or you will end up with
just one when using targets like 'sh4-linux-gnu'.
The resulting toolchain can't even build a kernel as the kernel needs to build
with the nofpu flag to be sure that no fpu ops are generated.
Here we restore the gcc-3.x behavior; the additional overhead of building all
of these multilibs by default is negligible.

===================================================================
dlopen cloog-isl library rather than link to it directly. This prevents
cloog upgrades that change the soname from breaking the compiler.
http://pkgs.fedoraproject.org/cgit/gcc.git/tree/gcc5-isl-dl.patch
In FreeBSD dlopen is part of libc so we can't just hardcode -ldl.
We abuse the existing plugin check logic to pull out that info.

* genpreds.c (struct constraint_data): Add maybe_allows_reg and
maybe_allows_mem bitfields.
(maybe_allows_none_start, maybe_allows_none_end,
maybe_allows_reg_start, maybe_allows_reg_end, maybe_allows_mem_start,
maybe_allows_mem_end): New variables.
(compute_maybe_allows): New function.
(add_constraint): Use it to initialize maybe_allows_reg and
maybe_allows_mem fields.
(choose_enum_order): Sort the non-is_register/is_const_int/is_memory/
is_address constraints such that those that allow neither mem nor
reg come first, then those that only allow reg but not mem, then
those that only allow mem but not reg, then the rest.
(write_allows_reg_mem_function): New function.
(write_tm_preds_h): Call it.
* stmt.c (parse_output_constraint, parse_input_constraint): Use
the generated insn_extra_constraint_allows_reg_mem function
instead of always setting *allows_reg = true; *allows_mem = true;
for unknown extra constraints.
* gcc.target/aarch64/c-output-template-4.c: New test.
