Import of unmodified (but trimmed) gcc-2.7.2. The bigger parts of the non-i386, non-unix, and generatable files have been trimmed, but can easily be added in later if needed. gcc-2.7.2.1 will follow shortly, it's a very small delta to this and it's handy to have both available for reference for such little cost. The freebsd-specific changes will then be committed, and once the dust has settled, the bmakefiles will be committed to use this code.

/* This is the final pass of the compiler.
It looks at the rtl code for a function and outputs assembler code.
Call `final_start_function' to output the assembler code for function entry,
`final' to output assembler code for some RTL code,
`final_end_function' to output assembler code for function exit.
If a function is compiled in several pieces, each piece is
output separately with `final'.
Some optimizations are also done at this level.
Move instructions that were made unnecessary by good register allocation
are detected and omitted from the output. (Though most of these
are removed by the last jump pass.)
Instructions to set the condition codes are omitted when it can be
seen that the condition codes already had the desired values.
In some cases it is sufficient if the inherited condition codes
have related values, but this may require the following insn
(the one that tests the condition codes) to be modified.
The code for the function prologue and epilogue are generated
