++   It usually pays to define several simpler macros to serve as subroutines for
++   this one.  Otherwise it may be too complicated to understand.
++
++   This macro must exist in two variants: a strict variant and a non-strict
++   one.  The strict variant is used in the reload pass.  It must be defined so
++   that any pseudo-register that has not been allocated a hard register is
++   considered a memory reference.  In contexts where some kind of register is
++   required, a pseudo-register with no hard register must be rejected.
++
++   The non-strict variant is used in other passes.  It must be defined to
++   accept all pseudo-registers in every context where some kind of register is
++   required.
++
++   Compiler source files that want to use the strict variant of this macro
++   define the macro `REG_OK_STRICT'.  You should use an `#ifdef REG_OK_STRICT'
++   conditional to define the strict variant in that case and the non-strict
++   variant otherwise.
++
++   Subroutines to check for acceptable registers for various purposes (one for
++   base registers, one for index registers, and so on) are typically among the
++   subroutines used to define `GO_IF_LEGITIMATE_ADDRESS'.  Then only these
++   subroutine macros need have two variants; the higher levels of macros may be
++   the same whether strict or not.
++
++   Normally, constant addresses which are the sum of a `symbol_ref' and an
++   integer are stored inside a `const' RTX to mark them as constant.
++   Therefore, there is no need to recognize such sums specifically as
++   legitimate addresses.  Normally you would simply recognize any `const' as
++   legitimate.
++
++   Usually `PRINT_OPERAND_ADDRESS' is not prepared to handle constant sums that
++   are not marked with `const'.  It assumes that a naked `plus' indicates
++   indexing.  If so, then you *must* reject such naked constant sums as
++   illegitimate addresses, so that none of them will be given to
++   `PRINT_OPERAND_ADDRESS'.
++
++   On some machines, whether a symbolic address is legitimate depends on the
++   section that the address refers to.  On these machines, define the macro
++   `ENCODE_SECTION_INFO' to store the information into the `symbol_ref', and
++   then check for it here.  When you see a `const', you will have to look
++   inside it to find the `symbol_ref' in order to determine the section.
++
++   The best way to modify the name string is by adding text to the beginning,
++   with suitable punctuation to prevent any ambiguity.  Allocate the new name
++   in `saveable_obstack'.  You will have to modify `ASM_OUTPUT_LABELREF' to
++   remove and decode the added text and output the name accordingly, and define
++   `STRIP_NAME_ENCODING' to access the original name string.
++
++   You can check the information stored here into the `symbol_ref' in the
++   definitions of the macros `GO_IF_LEGITIMATE_ADDRESS' and
++   `PRINT_OPERAND_ADDRESS'.  */

+	This patch brings over a few features from MirBSD:
+	* -fhonour-copts
+	  If this option is not given, it's warned (depending
+	  on environment variables). This is to catch errors
+	  of misbuilt packages which override CFLAGS themselves.
+	* -Werror-maybe-reset
+	  Has the effect of -Wno-error if GCC_NO_WERROR is
+	  set and not '0', a no-operation otherwise. This is
+	  to be able to use -Werror in "make" but prevent
+	  GNU autoconf generated configure scripts from
+	  freaking out.
+	* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks
+	  the default for -O2/-Os, because they trigger gcc bugs
+	  and can delete code with security implications.
+
+	This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+	with copyright assignment to the FSF in effect.
