Hi all,
I have a wild hair to spend some time (but no promises as
to how much) porting JDK2 to the alpha. A couple of questions
come to mind immediately after doing some work on the i386
port.
1) What are the contents of sigjmp_buf._sjb[*]? Any pointers
to some good Alpha assembly language docs would be great
as I'd really like to understand the contents of
src/lib/libc/alpha/gen/{,sig}setjmp.S.
2) Is there any state that I need to worry about maintaining
when switching contexts that {,sig}setjmp and {,sig}longjmp
don't already do for me? I know the Alpha doesn't have
FP registers, but for instance on the i386 you have to
(re)store the FPU mask when switching contexts. Anything like
this on the Alpha that I should be aware of?
TIA.
