-+## used.
-+## The MULTILIB_OPTIONS macro lists the set of options for which special
-+## versions of libgcc.a must be built. Write options that are mutually
-+## incompatible side by side, separated by a slash. Write options that may
-+## be used together separated by a space. The build procedure will build
-+## all combinations of compatible options.
-+##
-+## For example, if you set MULTILIB_OPTIONS to m68000/m68020 msoft-float,
-+## Makefile will build special versions of libgcc.a using the following
-+## sets of options: -m68000, -m68020, -msoft-float, -m68000 -msoft-float,

-+@cindex Altera Nios II options
-+
-+These are the @samp{-m} options defined for the Altera Nios II
-+processor.
-+
-+@table @gcctabopt
-+
-+@item -msmallc
-+@opindex msmallc
-+Link with a limited version of the C library, -lsmallc. For more
-+information see the C Library Documentation.
-+
-+
-+@item -mbypass-cache
-+@itemx -mno-bypass-cache
-+@opindex mno-bypass-cache
-+@opindex mbypass-cache
-+Force all load and store instructions to always bypass cache by
-+using io variants of the instructions. The default is to not
-+bypass the cache.
-+
-+@item -mno-cache-volatile
-+@itemx -mcache-volatile
-+@opindex mcache-volatile
-+@opindex mno-cache-volatile
-+Volatile memory access bypass the cache using the io variants of
-+the ld and st instructions. The default is to cache volatile
-+accesses.
-+
-+-mno-cache-volatile is deprecated and will be deleted in a
-+future GCC release.
-+
-+
-+@item -mno-inline-memcpy
-+@itemx -minline-memcpy
-+@opindex mno-inline-memcpy
-+@opindex minline-memcpy
-+Do not inline memcpy. The default is to inline when -O is on.
-+
-+
-+@item -mno-fast-sw-div
-+@itemx -mfast-sw-div
-+@opindex mno-fast-sw-div
-+@opindex mfast-sw-div
-+Do no use table based fast divide for small numbers. The default
-+is to use the fast divide at -O3 and above.
-+
-+
-+@item -mno-hw-mul
-+@itemx -mhw-mul
-+@itemx -mno-hw-mulx

-+@opindex mno-hw-div
-+@opindex mhw-div
-+Enable or disable emitting @code{mul}, @code{mulx} and @code{div} family of
-+instructions by the compiler. The default is to emit @code{mul}
-+and not emit @code{div} and @code{mulx}.
-+
-+The different combinations of @code{mul} and @code{mulx} instructions
-+generate a different multilib options.
-+
-+@item -mno-stack-check
-+@itemx -mstack-check
-+@opindex no-stack-check
-+@opindex stack-check
-+Enables or disables the checking for sufficient memory when
-+items are pushed onto the stack. A checked and non-checked
-+version of each of the multilibs is provided.
-+
-+@item -msys-crt0=@var{startfile}
-+@opindex msys-crt0
-+@var{startfile} is the file name of the startfile (crt0) to use
-+when linking. The default is crt0.o that comes with libgloss
-+and is only suitable for use with the instruction set
-+simulator.
-+
-+@item -msys-lib=@var{systemlib}
-+@itemx -msys-lib=nosys
-+@opindex msys-lib
-+@var{systemlib} is the library name of the library which provides
-+the system calls required by the C library, e.g. @code{read}, @code{write}
-+etc. The default is to use nosys, this library provides
-+stub implementations of the calls and is part of libgloss.
-+
-+@item -mno-reverse-bitfields
-+@itemx -mreverse-bitfields
-+@opindex mno-reverse-bitfields
-+@opindex mreverse-bitfields
-+When enabled, bitfields within a struct are allocated in reverse order.
-+This is useful with legacy code that depends on the (inherently
-+non-portable) ordering of bitfields via a union. Given:
-+
-+@smallexample
-+struct inner
-+@{
-+ unsigned int a:1;
-+ unsigned int b:31;
-+@};
-+
-+union outer
-+@{
-+ struct inner inner;
-+ unsigned int val;
-+@};
-+
-+unsigned int f()
-+@{
-+ union outer o;
-+ o.inner.a = 1;
-+ o.inner.b = 0;
-+ return o.val;
-+@}
-+@end smallexample
-+
-+a call to @code{f} will return 1 when compiled with
-+@option{-mno-reverse-bitfields} (the default), or 2147483648 when
-+compiled with @option{-mreverse-bitfields}.
-+
-+For structures that are a multiple of 32 bits wide, the reversal is
-+done 32 bits at a time. For structures that are an odd multiple of 16
-+bits wide, the reversal is done 16 bits at a time. For structures
-+that are an odd multiple of 8 bits wide, the reversal is done 8 bits
-+at a time. The size of a structure (as measured by the @code{sizeof}
-+operator) never changes between @option{-mno-reverse-bitfields} and
-+@option{-mreverse-bitfields}. Nonetheless, there can be some
-+confusing corner cases with structs where the compiler has to add
-+additional padding to meet alignment restrictions. Consider:
-+
-+@smallexample
-+struct inner
-+@{
-+ unsigned int a:1;
-+ unsigned int b:15;
-+@};
-+
-+union outer
-+@{
-+ struct inner inner;
-+ unsigned int val;
-+@};
-+
-+unsigned int f()
-+@{
-+ union outer o;
-+ o.val = 0;
-+ o.inner.b = 1;
-+ return o.val;
-+@}
-+@end smallexample
-+
-+a call to @code{f} will return 2 when compiled with
-+@option{-mno-reverse-bitfields} (the default), or 65536 when compiled
-+with @option{-mreverse-bitfields}. This is because @code{sizeof
-+(inner)} is 4 in both cases. In the @option{-mno-reverse-bitfields}
-+case, the compiler pads the struct at the end to be 4 bytes long,
-+effectively doing:
-+
-+@smallexample
-+struct inner
-+@{
-+ unsigned int a:1;
-+ unsigned int b:15;
-+ unsigned int padding:16;
-+@};
-+@end smallexample
-+
-+In the @option{-mreverse-bitfields} case, the hidden padding is
-+reversed along with everything else, yielding the equivalent of:
-+
-+@smallexample
-+struct inner
-+@{
-+ unsigned int padding:16;
-+ unsigned int b:15;
-+ unsigned int a:1;
-+@};
-+@end smallexample
-+
-+Of course, if we would rather that @code{sizeof (inner)} was 2, we could
-+write the struct as:
-+
-+@smallexample
-+struct inner
-+@{
-+ unsigned short a:1;
-+ unsigned short b:15;
-+@};
-+@end smallexample
-+
-+and the padding would go away.
-+
-+In some cases, especially when using the @code{__packed__} attribute,
-+there is no well-defined bit reversal that is possible: the compiler
-+will issue an error message in this case. Consider:
-+
-+@smallexample
-+struct invalid
-+@{
-+ unsigned int f1:1;
-+ unsigned int f2:15;
-+ unsigned int f3:4;
-+ unsigned int f4:4;
-+@} __attribute__ ((__packed__));
-+@end smallexample
-+
-+Since @code{sizeof (invalid)} is 3, we are forced to try reversing
-+individual bytes in the struct. But f2 is more than a byte wide, so
-+we can't reverse it and still have it be contiguous. Similar cases
-+occur when dealing with arrays or other large contiguous objects:
-+
-+@smallexample
-+struct invalid2
-+@{
-+ unsigned char f1[5];
-+ unsigned char f2[3];
-+@};
-+@end smallexample
-+
-+You'll have to rewrite the affected structs to say exactly what you
-+mean in odd cases like that.
-+
-+Finally, note that individual fields are sized as a whole. The structs
-+
-+@smallexample
-+struct array1
-+@{
-+ unsigned char f1[3];
-+ unsigned char f2;
-+@}
-+@end smallexample
-+
-+and:
-+
-+@smallexample
-+struct array2
-+@{
-+ unsigned char f1a;
-+ unsigned char f1b;
-+ unsigned char f1c;
-+ unsigned char f2;
-+@}
-+@end smallexample
-+
-+are not equivalent. When compiled with @option{-mreverse-bitfields},
-+they behave the same as:
-+
-+@smallexample
-+struct array1r
-+@{
-+ unsigned char f2;
-+ unsigned char f1[3];
-+@}
-+@end smallexample
-+
-+and:
-+
-+@smallexample
-+struct array2r
-+@{
-+ unsigned char f2;
-+ unsigned char f1c;
-+ unsigned char f1b;
-+ unsigned char f1a;
-+@}
-+@end smallexample
-+
-+would, respectively, when compiled with
-+@option{-mno-reverse-bitfields}. In particular, f1 is treated as a
-+single contiguous 24-bit object for purposes of reversal, while f1a,
-+f1b, and f1c are treated as individual 8-bit objects that need not
-+(and do not) remain contiguous. Use caution.

-#
-# Submitted:
-#
-# Dimitry Andric <dimitry@andric.com>, 2004-05-01
-#
-# Description:
-#
-# Nicholas Pitre released this patch for gcc soft-float support here:
-# http://lists.arm.linux.org.uk/pipermail/linux-arm/2003-October/006436.html
-#
-# This version has been adapted to work with gcc 3.4.0.
-#
-# The original patch doesn't distinguish between softfpa and softvfp modes
-# in the way Nicholas Pitre probably meant. His description is:
-#
-# "Default is to use APCS-32 mode with soft-vfp. The old Linux default for
-# floats can be achieved with -mhard-float or with the configure
-# --with-float=hard option. If -msoft-float or --with-float=soft is used then
-# software float support will be used just like the default but with the legacy
-# big endian word ordering for double float representation instead."
-#
-# Which means the following:
-#
-# * If you compile without -mhard-float or -msoft-float, you should get
-# software floating point, using the VFP format. The produced object file
-# should have these flags in its header:
-#
-# private flags = 600: [APCS-32] [VFP float format] [software FP]
-#
-# * If you compile with -mhard-float, you should get hardware floating point,
-# which always uses the FPA format. Object file header flags should be:
-#
-# private flags = 0: [APCS-32] [FPA float format]
-#
-# * If you compile with -msoft-float, you should get software floating point,
-# using the FPA format. This is done for compatibility reasons with many
-# existing distributions. Object file header flags should be:
-#
-# private flags = 200: [APCS-32] [FPA float format] [software FP]
-#
-# The original patch from Nicholas Pitre contained the following constructs:
-#
-# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
-# %{mhard-float:-mfpu=fpa} \
-# %{!mhard-float: %{msoft-float:-mfpu=softfpa;:-mfpu=softvfp}}"
-#
-# However, gcc doesn't accept this ";:" notation, used in the 3rd line. This
-# is probably the reason Robert Schwebel modified it to:
-#
-# #define SUBTARGET_EXTRA_ASM_SPEC "%{!mcpu=*:-mcpu=xscale} \
-# %{mhard-float:-mfpu=fpa} \
-# %{!mhard-float: %{msoft-float:-mfpu=softfpa -mfpu=softvfp}}"
-#
-# But this causes the following behaviour:
-#
-# * If you compile without -mhard-float or -msoft-float, the compiler generates
-# software floating point instructions, but *nothing* is passed to the
-# assembler, which results in an object file which has flags:
-#
-# private flags = 0: [APCS-32] [FPA float format]
-#
-# This is not correct!
-#
-# * If you compile with -mhard-float, the compiler generates hardware floating
-# point instructions, and passes "-mfpu=fpa" to the assembler, which results
-# in an object file which has the same flags as in the previous item, but now
-# those *are* correct.
-#
-# * If you compile with -msoft-float, the compiler generates software floating
-# point instructions, and passes "-mfpu=softfpa -mfpu=softvfp" (in that
-# order) to the assembler, which results in an object file with flags:
-#
-# private flags = 600: [APCS-32] [VFP float format] [software FP]
-#
-# This is not correct, because the last "-mfpu=" option on the assembler
-# command line determines the actual FPU convention used (which should be FPA
-# in this case).
-#
-# Therefore, I modified this patch to get the desired behaviour. Every
-# instance of the notation:
-#
-# %{msoft-float:-mfpu=softfpa -mfpu=softvfp}
-#
-# was changed to:
-#
-# %{msoft-float:-mfpu=softfpa} %{!msoft-float:-mfpu=softvfp}
-#
-# I also did the following:
-#
-# * Modified all TARGET_DEFAULT macros I could find to include ARM_FLAG_VFP, to
-# be consistent with Nicholas' original patch.
-# * Removed any "msoft-float" or "mhard-float" from all MULTILIB_DEFAULTS
-# macros I could find. I think that if you compile without any options, you
-# would like to get the defaults. :)
-# * Removed the extra -lfloat option from LIBGCC_SPEC, since it isn't needed
-# anymore. (The required functions are now in libgcc.)
