-@node Cross Runtime
-@subsection @file{libgcc.a} and Cross-Compilers
-
-Code compiled by GNU CC uses certain runtime support functions
-implicitly. Some of these functions can be compiled successfully with
-GNU CC itself, but a few cannot be. These problem functions are in the
-source file @file{libgcc1.c}; the library made from them is called
-@file{libgcc1.a}.
-
-When you build a native compiler, these functions are compiled with some
-other compiler--the one that you use for bootstrapping GNU CC.
-Presumably it knows how to open code these operations, or else knows how
-to call the run-time emulation facilities that the machine comes with.
-But this approach doesn't work for building a cross-compiler. The
-compiler that you use for building knows about the host system, not the
-target system.
-
-So, when you build a cross-compiler you have to supply a suitable
-library @file{libgcc1.a} that does the job it is expected to do.
-
-To compile @file{libgcc1.c} with the cross-compiler itself does not
-work. The functions in this file are supposed to implement arithmetic
-operations that GNU CC does not know how to open code for your target
-machine. If these functions are compiled with GNU CC itself, they
-will compile into infinite recursion.
-
-On any given target, most of these functions are not needed. If GNU CC
-can open code an arithmetic operation, it will not call these functions
-to perform the operation. It is possible that on your target machine,
-none of these functions is needed. If so, you can supply an empty
-library as @file{libgcc1.a}.
-
-Many targets need library support only for multiplication and division.
-If you are linking with a library that contains functions for
-multiplication and division, you can tell GNU CC to call them directly
-by defining the macros @code{MULSI3_LIBCALL}, and the like. These
-macros need to be defined in the target description macro file. For
-some targets, they are defined already. This may be sufficient to
-avoid the need for libgcc1.a; if so, you can supply an empty library.
-
-Some targets do not have floating point instructions; they need other
-functions in @file{libgcc1.a}, which do floating arithmetic.
-Recent versions of GNU CC have a file which emulates floating point.
-With a certain amount of work, you should be able to construct a
-floating point emulator that can be used as @file{libgcc1.a}. Perhaps
-future versions will contain code to do this automatically and
-conveniently. That depends on whether someone wants to implement it.
-
-Some embedded targets come with all the necessary @file{libgcc1.a}
-routines written in C or assembler. These targets build
-@file{libgcc1.a} automatically and you do not need to do anything
-special for them. Other embedded targets do not need any
-@file{libgcc1.a} routines since all the necessary operations are
-supported by the hardware.
-
-If your target system has another C compiler, you can configure GNU CC
-as a native compiler on that machine, build just @file{libgcc1.a} with
-@samp{make libgcc1.a} on that machine, and use the resulting file with
-the cross-compiler. To do this, execute the following on the target
-machine:
-
-@example
-cd @var{target-build-dir}
-./configure --host=sparc --target=sun3
-make libgcc1.a
-@end example
-
-@noindent
-And then this on the host machine:
-
-@example
-ftp @var{target-machine}
-binary
-cd @var{target-build-dir}
-get libgcc1.a
-quit
-@end example
-
-Another way to provide the functions you need in @file{libgcc1.a} is to
-define the appropriate @code{perform_@dots{}} macros for those
-functions. If these definitions do not use the C arithmetic operators
-that they are meant to implement, you should be able to compile them
-with the cross-compiler you are building. (If these definitions already
-exist for your target file, then you are all set.)
-
-To build @file{libgcc1.a} using the perform macros, use
-@samp{LIBGCC1=libgcc1.a OLDCC=./xgcc} when building the compiler.
-Otherwise, you should place your replacement library under the name
-@file{libgcc1.a} in the directory in which you will build the
-cross-compiler, before you run @code{make}.
-
@node Cross Headers
@subsection Cross-Compilers and Header Files
@subsection Actually Building the Cross-Compiler
Now you can proceed just as for compiling a single-machine compiler
-through the step of building stage 1. If you have not provided some
-sort of @file{libgcc1.a}, then compilation will give up at the point
-where it needs that file, printing a suitable error message. If you
-do provide @file{libgcc1.a}, then building the compiler will automatically
-compile and link a test program called @file{libgcc1-test}; if you get
-errors in the linking, it means that not all of the necessary routines
-in @file{libgcc1.a} are available.
-
-You must provide the header file @file{float.h}. One way to do this is
-to compile @file{enquire} and run it on your target machine. The job of
-@file{enquire} is to run on the target machine and figure out by
-experiment the nature of its floating point representation.
-@file{enquire} records its findings in the header file @file{float.h}.
-If you can't produce this file by running @file{enquire} on the target
-machine, then you will need to come up with a suitable @file{float.h} in
-some other way (or else, avoid using it in your programs).
+through the step of building stage 1.
+
+If your target is exotic, you may need to provide the header file
+@file{float.h}.One way to do this is to compile @file{enquire} and run
+it on your target machine. The job of @file{enquire} is to run on the

Do not try to build stage 2 for a cross-compiler. It doesn't work to
rebuild GNU CC as a cross-compiler using the cross-compiler, because

+affects both how library calls are generated and how the library
+routines in @file{libgcc.a} accept their arguments. It is useful on
machines where floating and fixed point arguments are passed
differently, such as the i860.
-@findex FLOAT_ARG_TYPE
-@item FLOAT_ARG_TYPE
-Define this macro to override the type used by the library routines to
-pick up arguments of type @code{float}. (By default, they use a union
-of @code{float} and @code{int}.)
-
-The obvious choice would be @code{float}---but that won't work with
-traditional C compilers that expect all arguments declared as @code{float}
-to arrive as @code{double}. To avoid this conversion, the library routines
-ask for the value as some other type and then treat it as a @code{float}.
-
-On some systems, no other type will work for this. For these systems,
-you must use @code{LIBGCC_NEEDS_DOUBLE} instead, to force conversion of
-the values @code{double} before they are passed.
-
-@findex FLOATIFY
-@item FLOATIFY (@var{passed-value})
-Define this macro to override the way library routines redesignate a
-@code{float} argument as a @code{float} instead of the type it was
-passed as. The default is an expression which takes the @code{float}
-field of the union.
-
-@findex FLOAT_VALUE_TYPE
-@item FLOAT_VALUE_TYPE
-Define this macro to override the type used by the library routines to
-return values that ought to have type @code{float}. (By default, they
-use @code{int}.)
-
-The obvious choice would be @code{float}---but that won't work with
-traditional C compilers gratuitously convert values declared as
-@code{float} into @code{double}.
-
-@findex INTIFY
-@item INTIFY (@var{float-value})
-Define this macro to override the way the value of a
-@code{float}-returning library routine should be packaged in order to
-return it. These functions are actually declared to return type
-@code{FLOAT_VALUE_TYPE} (normally @code{int}).
-
-These values can't be returned as type @code{float} because traditional
-C compilers would gratuitously convert the value to a @code{double}.
-
-A local variable named @code{intify} is always available when the macro
-@code{INTIFY} is used. It is a union of a @code{float} field named
-@code{f} and a field named @code{i} whose type is
-@code{FLOAT_VALUE_TYPE} or @code{int}.
-
-If you don't define this macro, the default definition works by copying
-the value through that union.
-
-@findex nongcc_SI_type
-@item nongcc_SI_type
-Define this macro as the name of the data type corresponding to
-@code{SImode} in the system's own C compiler.
-
-You need not define this macro if that type is @code{long int}, as it usually
-is.
-
-@findex nongcc_word_type
-@item nongcc_word_type
-Define this macro as the name of the data type corresponding to the

-is.
-
-@findex perform_@dots{}
-@item perform_@dots{}
-Define these macros to supply explicit C statements to carry out various
-arithmetic operations on types @code{float} and @code{double} in the
-library routines in @file{libgcc1.c}. See that file for a full list
-of these macros and their arguments.

-On most machines, you don't need to define any of these macros, because
-the C compiler that comes with the system takes care of doing them.
