Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

-68060 FLOATING-POINT SOFTWARE PACKAGE (Library version)
---------------------------------------------------------
-
-The file fplsp.sa contains the "Library version" of the
-68060SP Floating-Point Software Package. The routines
-included in this module can be used to emulate the
-FP instructions not implemented in 68060 hardware. These
-instructions normally take exception vector #11
-"FP Unimplemented Instruction".
-
-By re-compiling a program that uses these instructions, and
-making subroutine calls in place of the unimplemented
-instructions, a program can avoid the overhead associated
-with taking the exception.
-
-Release file format:
---------------------
-The file fplsp.sa is essentially a hexadecimal image of the
-release package. This is the ONLY format which will be supported.
-The hex image was created by assembling the source code and
-then converting the resulting binary output image into an
-ASCII text file. The hexadecimal numbers are listed
-using the Motorola Assembly Syntax assembler directive "dc.l"
-(define constant longword). The file can be converted to other
-assembly syntaxes by using any word processor with a global
-search and replace function.
-
-To assist in assembling and linking this module with other modules,
-the installer should add a symbolic label to the top of the file.
-This will allow calling routines to access the entry points
-of this package.
-
-The source code fplsp.s has also been included but only for
-documentation purposes.
-
-Release file structure:
------------------------
-The file fplsp.sa contains an "Entry-Point" section and a
-code section. The FPLSP has no "Call-Out" section. The first section
-is the "Entry-Point" section. In order to access a function in the
-package, a program must "bsr" or "jsr" to the location listed
-below in "68060FPLSP entry points" that corresponds to the desired
-function. A branch instruction located at the selected entry point
-within the package will then enter the correct emulation code routine.
-
-The entry point addresses at the beginning of the package will remain
-fixed so that a program calling the routines will not have to be
-re-compiled with every new 68060FPLSP release.
-
-There are 3 entry-points for each instruction type: single precision,
-double precision, and extended precision.
-
-As an example, the "fsin" library instruction can be passed an
-extended precision operand if program executes:
-
-# fsin.x fp0
-
- fmovm.x &0x01,-(%sp) # pass operand on stack
- bsr.l _060FPLSP_TOP+0x1a8 # branch to fsin routine
- add.l &0xc,%sp # clear operand from stack
-
-Upon return, fp0 holds the correct result. The FPSR is
-set correctly. The FPCR is unchanged. The FPIAR is undefined.
-
-Another example. This time, a dyadic operation:
-
-# frem.s %fp1,%fp0
-
- fmov.s %fp1,-(%sp) # pass src operand
- fmov.s %fp0,-(%sp) # pass dst operand
- bsr.l _060FPLSP_TOP+0x168 # branch to frem routine
- addq.l &0x8,%sp # clear operands from stack
-
-Again, the result is returned in fp0. Note that BOTH operands
-are passed in single precision format.
-
-Exception reporting:
---------------------
-The package takes exceptions according to the FPCR value upon subroutine
-entry. If an exception should be reported, then the package forces
-this exception using implemented floating-point instructions.
-For example, if the instruction being emulated should cause a
-floating-point Operand Error exception, then the library routine
-executes an FMUL of a zero and an infinity to force the OPERR
-exception. Although the FPIAR will be undefined for the enabled
-Operand Error exception handler, the user will at least be able
-to record that the event occurred.
-
-Miscellaneous:
---------------
-The package does not attempt to correctly emulate instructions
-with Signalling NAN inputs. Use of SNANs should be avoided with
-this package.
-
-The fabs/fadd/fdiv/fint/fintrz/fmul/fneg/fsqrt/fsub entry points
-are provided for the convenience of older compilers that make
-subroutine calls for all fp instructions. The code does NOT emulate
-the instruction but rather simply executes it.
