CVS commit: src/lib/libc/arch/sparc

Module Name:    src
Committed By:   mrg
Date:           Sun Sep  3 21:41:45 UTC 2023

Modified Files:
        src/lib/libc/arch/sparc/gen: longjmp.c setjmp.S
Added Files:
        src/lib/libc/arch/sparc/gen: sparc_longjmp.h

Log Message:
avoid array-bounds issues by using more complete types.

also, don't cast to a type that includes an extra, unused, member.

while here, replace the hard coded offsets in setjmp.S and some
asserts in longjmp.c with assym.h and shared structures for all
the movings parts, and asserts based upon those structures.

avoids GCC 12 warnings.
