Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.

ABI police: avoid cluttering global registers %g2 and %g7. Not quite there
yet for %g2, but the target is not very well defined. %g7 should be clean
now.

In handwritten asm use -fPIC code instead of -fpic, our libc has grown
large enough for GOT to be larger than 8k.

While here kill redundant PIC ifdefs in setjmp.S - sparc "call"
instruction is piccy

In handwritten asm use -fPIC code instead of -fpic, our libc has grown
large enough for GOT to be larger than 8k.

While here kill redundant PIC ifdefs in setjmp.S - sparc "call"
instruction is piccy by itself.

Prettify. Avoid code duplication.
Same object code is generated.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Revert previous: .S files are currently compiled with -traditional-cpp,
so __STDC__ is _not_ always defined.

__STDC__ is always defined on NetBSD.

Add a macro "CALL()" to call a function correctly in the pic and non pic
case. Write ERROR() in terms of call.

Add a _SYSCALL(entry,syscall) macro like the one found on other
architectures.

_ASM_LABEL(curbrk) to _C_LABEL(__cerror) and _C_LABEL(__curbrk), respectively,

Fix typo in last commit.

Consistency: distinguish between PSEUDO() and PSEUDO_NOERROR().

Flesh out the `noerror' syscall macros.

SYSCALL_NOERROR(x): Like SYSCALL except that "x" is a syscall
that can never fail.

Added new macros:
SYSCALL_NOERROR(x): Like SYSCALL except that "x" is a syscall
that can never fail.

RSYSCALL_NOERROR(x): Like RSYSCALL except that "x" is a syscall
that can never fail.

These macros simply call SYSCALL / RSYSCALL, and serve as placeholders
until an optimized implementation is done.
