Add m68k assembler version of __muldi3().
This is intended for 68060: - GCC does not emit __muldi3() for 68020-40, that have 32 * 32 --> 64 mulul - mulsl (and moveml), used in this code, are not implemented for 68010
In comparison with that from compiler_rt, this version saves: - 12% of processing time - 12 bytes of stack - 50 bytes of code size Also, slightly faster, memory saving, and smaller than libgcc version.
By examining with evcnt(9), __muldi3() is invoked more than 1000 times per sec by kernel, which should justify to introduce assembler version of this function.

Restrict usage of m68k assembler versions of {,u}divsi3 and {,u}divsi3 to kernel and bootloader for 68010.
They requires a special calling convention to udivsi3, and cannot to be mixed up in normal routines provided by libgcc or compiler_rt. Although, there's no problem for using them in a controlled situation, i.e., kernel and standalone programs.
Note that this does not affect at all m68k ports other than sun2, since codes generated by gcc do not call these routines.
Assembler files are moved from common/lib/libc/arch/m68k/gen to sys/lib/libkern/arch/m68k in order not to be compiled in libc.

Push back the descriptions of NaN formats, and descriptions of the distinction between signalling NaNs and quiet NaNs back into the machine-dependent headers; treat the implementation of __nanf in the same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs to the implementation, and unlike our headers used to suggest they're not identical in the interpretation of the fraction's MSb; in due course, make those of hppa, mips, sh3, and sh5 reflect reality.

branches: 1.25.2; Add support to build the mac68k port with soft-float enabled (i.e., setting MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work in machines with the 68040LC chip (those that have the FPU bug).
All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>, with some very minor changes by me; the patches were being posted to the port-mac68k mailing list. It has been tested for a long time by several users, including me.
I have just verified that regular releases, as well as soft-float ones, continue to build.
There have been no objections to this patch since I asked for them in July in the port-mac68k list.

Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES. This is a change of behaviour. If a Makefile wants the clean semantics it must specifically append to CLEANFILES. Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".

Clean up some rampant code duplication wrt ieee number handling: - Add alignment-safe double and float unions. - Use the above for the __infinity and __nan constants on all architectures that use the standard ieee754 representation of those constants. - Add a single copy of various ieee754 math functions (frexp, isinf, isnan, ldexp and modf) that had numerous duplicates among the arch-specific directories. - Use the above functions on all architectures where the generic C versions where used. Architectures that had local assembly routines are untouched (for those functions only).

Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc.

With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp() doesn't use excessive amounts of system cpu time. Without any of those defines, the normal assembler version using FSCALE is included, for the benefit of M68020 and M68030 users, or M68040/M68060 users where the ldexp performance is no bottleneck.

Push back the descriptions of NaN formats, and descriptions of the distinction between signalling NaNs and quiet NaNs back into the machine-dependent headers; treat the implementation of __nanf in the same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs to the implementation, and unlike our headers used to suggest they're not identical in the interpretation of the fraction's MSb; in due course, make those of hppa, mips, sh3, and sh5 reflect reality.

branches: 1.25.2; Add support to build the mac68k port with soft-float enabled (i.e., setting MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work in machines with the 68040LC chip (those that have the FPU bug).
All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>, with some very minor changes by me; the patches were being posted to the port-mac68k mailing list. It has been tested for a long time by several users, including me.
I have just verified that regular releases, as well as soft-float ones, continue to build.
There have been no objections to this patch since I asked for them in July in the port-mac68k list.

Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES. This is a change of behaviour. If a Makefile wants the clean semantics it must specifically append to CLEANFILES. Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing specific .o dependencies with DPSRCS entries.

Clean up some rampant code duplication wrt ieee number handling: - Add alignment-safe double and float unions. - Use the above for the __infinity and __nan constants on all architectures that use the standard ieee754 representation of those constants. - Add a single copy of various ieee754 math functions (frexp, isinf, isnan, ldexp and modf) that had numerous duplicates among the arch-specific directories. - Use the above functions on all architectures where the generic C versions where used. Architectures that had local assembly routines are untouched (for those functions only).

Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.

branches: 1.6.2; ieee.h and ldexp.c taken from the powerpc port, for the benefit of 68040 and 68060 owners. With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp() doesn't use excessive amounts of system cpu time. Without any of those defines, the normal assembler version using FSCALE is included, for the benefit of M68020 and M68030 users, or M68040/M68060 users where the ldexp performance is no bottleneck. [Its not yet worked out how to include both library versions in a binary distribution, but you can build your own from source now if you need it.] For details, look at PR 3105.

Clean up some rampant code duplication wrt ieee number handling: - Add alignment-safe double and float unions. - Use the above for the __infinity and __nan constants on all architectures that use the standard ieee754 representation of those constants. - Add a single copy of various ieee754 math functions (frexp, isinf, isnan, ldexp and modf) that had numerous duplicates among the arch-specific directories. - Use the above functions on all architectures where the generic C versions where used. Architectures that had local assembly routines are untouched (for those functions only).

Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc.

Push back the descriptions of NaN formats, and descriptions of the distinction between signalling NaNs and quiet NaNs back into the machine-dependent headers; treat the implementation of __nanf in the same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs to the implementation, and unlike our headers used to suggest they're not identical in the interpretation of the fraction's MSb; in due course, make those of hppa, mips, sh3, and sh5 reflect reality.

branches: 1.25.2; Add support to build the mac68k port with soft-float enabled (i.e., setting MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work in machines with the 68040LC chip (those that have the FPU bug).
All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>, with some very minor changes by me; the patches were being posted to the port-mac68k mailing list. It has been tested for a long time by several users, including me.
I have just verified that regular releases, as well as soft-float ones, continue to build.
There have been no objections to this patch since I asked for them in July in the port-mac68k list.

Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES. This is a change of behaviour. If a Makefile wants the clean semantics it must specifically append to CLEANFILES. Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".

Push back the descriptions of NaN formats, and descriptions of the distinction between signalling NaNs and quiet NaNs back into the machine-dependent headers; treat the implementation of __nanf in the same spirit.
IEEE 754 leaves the distinction between signalling NaNs and quiet NANs to the implementation, and unlike our headers used to suggest they're not identical in the interpretation of the fraction's MSb; in due course, make those of hppa, mips, sh3, and sh5 reflect reality.

branches: 1.25.2; Add support to build the mac68k port with soft-float enabled (i.e., setting MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work in machines with the 68040LC chip (those that have the FPU bug).
All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>, with some very minor changes by me; the patches were being posted to the port-mac68k mailing list. It has been tested for a long time by several users, including me.
I have just verified that regular releases, as well as soft-float ones, continue to build.
There have been no objections to this patch since I asked for them in July in the port-mac68k list.

* Since there is no single portable IEEE 754 format for a long double, keep a common implementation of isinfl() and isnanl() to be used by platforms where `long double' == `double'; move others into machine-dependent code. * In due course, consider __VFP_FP__ on arm.

Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES. This is a change of behaviour. If a Makefile wants the clean semantics it must specifically append to CLEANFILES. Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".

Clean up some rampant code duplication wrt ieee number handling: - Add alignment-safe double and float unions. - Use the above for the __infinity and __nan constants on all architectures that use the standard ieee754 representation of those constants. - Add a single copy of various ieee754 math functions (frexp, isinf, isnan, ldexp and modf) that had numerous duplicates among the arch-specific directories. - Use the above functions on all architectures where the generic C versions where used. Architectures that had local assembly routines are untouched (for those functions only).

Move the bswap functions from libutil to libc (this bups the minor of libc and the major of libutil). For little-endian architectures merge the bnswap() assembly versions with nto* and hton* using symbols aliasing. Use symbol renaming for the bswap function in this case to avoid namespace pollution. Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian machines, common code for inline macros go in machine/byte_swap.h Sync libkern with libc. Adjust #include in kernel sources for machine/bswap.h.

branches: 1.6.2; ieee.h and ldexp.c taken from the powerpc port, for the benefit of 68040 and 68060 owners. With ``make M68040=1'' or ``make M68060=1'', we build a libc where the ldexp() doesn't use excessive amounts of system cpu time. Without any of those defines, the normal assembler version using FSCALE is included, for the benefit of M68020 and M68030 users, or M68040/M68060 users where the ldexp performance is no bottleneck. [Its not yet worked out how to include both library versions in a binary distribution, but you can build your own from source now if you need it.] For details, look at PR 3105.
