fvdl d191029b13 2 more bitnumber mistakes fixed while removing sahf. 2001-06-25 16:47:05 +00:00
fvdl c5b64cb062 Oops, when I replaced sahf with a btw, I made it test the wrong bit 
(2 vs. 10).
 2001-06-25 16:44:34 +00:00
fvdl 120d96874f %rbp -> %rsp in 2 cases. 2001-06-19 17:49:36 +00:00
fvdl 8ecba6c681 Modify the i387 code so that it can be shared between the i386 port 
and the x86_64 port. XXX some files should be distinct.

kleink 26c512aade Make these idempotent as far as the FPU register stack is concerned. 2000-09-26 07:28:23 +00:00
matt 94827a09a3 Well, duh! Use indexed addressing since that's why it's there. That way 
the code is PIC.  (mmm.  linker warning's about non-PIC code).

matt 584a2f53ee Clean up & prepare for ELF. Don't define isnan since it's in libc. Add a 
powf (really a wrapper for pow).

is 7c1da7b0c9 Regenerate, after changing internal label used for linkage to the wrapper 
scripts.
 2000-05-16 19:07:35 +00:00
is 9ba8ffc293 Change libm-68060 internal, but file external labels (used for linkage between 
wrapper functions and the Motorola code) to guarantee consistent protection
of the user namespace.
 2000-05-16 19:05:37 +00:00
is 287de693da Regenerated files after this change: 
Move each wrapper function to its own source file, such that redefining one
function doesn't give link errors when another one is pulled in from the
library.
Problem discovered by Klaus Klein.

kristerw 14e0e5307d The scalb* functions left data on the floting point register stack. 
Remove it before leaving the function.

The solution is taken from OpenBSD.

thorpej 688ff1ddf9 Correct think-o; this is an assembler source file (and the Makefile 
expected as such).

jtc 0ab3a0b137 It's necessary to use 64 bit precision to avoid errors in the least

jtc 5743dc5d7a Fix from Bruce Evans. Commited to FreeBSD earlier this month, but was 
never forwarded to me :-(.

> Clean up the FP stack before returning.  The i387 exp() leaked an FP
> register on its first call.  Subsequent calls reused the register so
> the leak didn't accumulate.

jtc 84fc678011 Use setne instead of setnel, new versions of gas balk at the bad mnemonic. 
Wrong mask was used in s_finitef.S.
