/* A C compound statement with a conditional `goto LABEL;' executed
if X (an RTX) is a legitimate memory address on the target machine
for a memory operand of mode MODE.
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. *Note Assembler Format::.
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'. */

machine for a memory operand of mode MODE.
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.
Typically among the subroutines used to define
`GO_IF_LEGITIMATE_ADDRESS' are subroutines to check for
acceptable registers for various purposes (one for base
registers, one for index registers, and so on). 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 macro definition, if any, is executed immediately after the
rtl for DECL has been created and stored in `DECL_RTL (DECL)'.
The value of the rtl will be a `mem' whose address is a
`symbol_ref'.
The usual thing for this macro to do is to a flag in the
`symbol_ref' (such as `SYMBOL_REF_FLAG') or to store a modified
name string in the `symbol_ref' (if one bit is not enough
information).
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.
You can also check the information stored in the `symbol_ref' in
the definition of `GO_IF_LEGITIMATE_ADDRESS' or
`PRINT_OPERAND_ADDRESS'.

/* A C compound statement with a conditional `goto LABEL;' executed if X (an
RTX) is a legitimate memory address on the target machine for a memory
operand of mode MODE.
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'. */

Define this macro if references to a symbol or a constant must be

The macro definition, if any, is executed under two circumstances. One
is immediately after the rtl for @var{decl} that represents a variable
