pre-processed, like other Alpha assembly files.

Fix layout of fields in jmp_buf. [N.B. we could make JMP_BUFLEN 9 if we want.]

Make __dtoul() actually DTRT. The calling convention was totally wrong, and
...
the `big' value should be 2^63, not 2^31.
Also, nuke __fixunsdfsi(), since this is never output by the sparc64 compiler.
2000-07-25 04:26:12 +00:00

Just use a store/load pair to get the pattern into the FP reg. This eliminates
...
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.

Add fixunssfsi and fixunsdfsi. These are provided by libgcc2.c in GCC 2.95,
...
but not in EGCS.
This version of fixunssfsi is almost exactly the arm32 version. fixunsdfsi is
mostly based on fixdfsi, but with simplifications for 64-bit integers.
Only minimal testing has been applied so far.

Initial commit of SoftFloat 2a import. This should provide a sensible
...
mostly-MI floating-point implementation for use by gcc -msoft-float.
It's currently only used by arm26, but should be usable by other ports
without too much hacking, assuming doubles and u_int64_ts are passed and
returned the same way, and FP formats are IEEEish.
