mycroft ae34e2ea6e Put jtc's notice back, since these are now roughly identical. 1995-04-09 23:32:53 +00:00
mycroft ac11de32c1 Actually, bitfields are faster on the '040; optimize for it, but adjust the
fields so that the mask and sticky bits are the same.

mycroft 99a6cfe734 Rewrite these to use the accrued exception byte for sticky flags, and to
avoid expensive bitfield instructions.

cgd 3f45f31f15 strange corner cases:
(1) zero top 32 bits for 32-bit unsigned ops; 32-bit value can
		be accidentally(?) sign-extended by the compiler/assembler.
	(2) fix return value for mod's that cause traps
1995-02-25 03:09:32 +00:00
jtc e7d917e6eb Remove extra "u" constraint that caused gcc 2.6.3 not to compile this file.
Note that gcc 2.4.5, the compiler we are currently using, still compiles it
correctly after this change.

cgd e4f5181d15 libc support for the alpha. more functions should be written in assembler,
but that's optimization.  8-)

for the "signal mask saved" appended to the end).
