Jeff Law 3d10b04f1e Fix various c99/gcc-14 issues in generic libgloss code
Similar to what's been done in the ports, but this time in generic code.

Add missing #includes to pick up prototypes.  Add prototypes for various
internal functions where needed.  Fix signatures of various functions to match
what's provided by the headers (read, sbrk, write, unlink).

Nearly done with this effort ;-)

Pushed to the trunk,

Jeff Law 7ef32a98cd Fix another missing header file for mcore libgloss
I guess I must have missed this when working through the trivial port specific
changes.

This adds an include of stdlib.h to get a prototype for exit().

Jeff Law 1df8f9f09b Fix epiphany libgloss for c99/gcc-14
So in this case we mostly need to include an internal header
(epiphany-syscalls.h).  In a few cases an explicit prototype is added.  We've
also got a return with no value in a function with a non-void return type.
Finally the asm_syscall interface expects a pointer as its first argument.  In
a few cases we've actually got an int (file descriptor) which we just cast to a
void *.

It's slightly more than Jeff J's pre-approval, but I think still reasonable.

Craig Blackmore 73bce6597c newlib: Fix long double for unsupported rounding modes and exceptions
RISC-V newlib fails to build for soft float multilibs since long double
support was enabled in:

  commit 04798b7bb6
  Author: Kito Cheng <kito.cheng@sifive.com>
  Date:   Mon Dec 4 15:41:39 2023 +0800

      RISC-V: Support long double math

      Long double for RISC-V is using 128 bit IEEE 754 format like Aarch64,
      so we reference AArch64 to support that.

The RISC-V soft floating point environment only supports the
FE_TONEAREST rounding mode and does not support exceptions.  Guard long
double rounding and exception support with ifdefs based on the presence
of the relevant rounding modes and exceptions.

Tested on gcc/g++ testsuite using RISC-V GNU Newlib Toolchain built by
riscv-gnu-toolchain with multilibs:

Jeff Law c1a61029fe Fix various v850 problems
These fixes fall into a few different buckets.  First c99 doesn't allow a
parameter without a type.  So in cases where the type had previously been an
implicit int, make it an explicit int.  Second, for return values, don't allow
them to be implicit ints either, make them explicit. In a few cases change c89
function definitions to c99 function definitions.   Lastly include <stdlib.h>
in sbrk.c to get the prototype for abort () which we call when we detect a
heap/stack collision.

Mike Frysinger 751a3427e0 libgloss: drop $(INCLUDES) when using $(AS)
Since $(AS) is the assembler, passing it a list of preprocessor include
flags doesn't make much sense.  The files aren't preprocessed which means
`#include` lines aren't respected, and while it would affect `.include`
usage, we never use that, and it's extremely unlikely to change.  Plus,
it's extremely unlikely we'd have .s files in common places to include vs
contained entirely within a specific arch dir, and at that point, it can
be included directly (with no flags), or the arch can add the unique set
of include paths that it needs for itself.

Jeff Law c2c9f05a05 libgloss fix for bfin port
gcc-14 will complain loudly both for calling a function without an in-scope
prototype or when the in scope prototype differs from the known signature.

"main" happens to be one of the functions the compiler knows about.  So not
only do we need to prototype it, we need to make sure the prototype matches
what GCC thinks it should be.

This fixes the bfin libgloss port to do the right thing for bfin-elf.

Jeff Law 57e311e0de Re: Fix moxie libgloss issues with c99
Two libgloss issues specific to moxie-elf that show up build with GCC trunk.

First, putnum.c uses "print" without a prototype.  So I added one based on the
function's definition in print.c.  Second sim-inbyte.c uses read, which comes
from unistd.h, so this adds a suitable #include.

Jeff Law 17a6aff334 Fix fr30 libgloss build
gcc-14 will default to c99 and as a result a fair amount of old code in newlib
(particularly libgloss) is failing to build.  I don't offhand know how many
patches will be necessary to fix the various failures. I'll just pick them off
one by one from my tree.

This particular patch works around the return-mismatch problem syscalls.c for
fr30.

That file is a bit odd in that most functions are declared as returning an
integer, but the implementations look like:

> int
> _read (file, ptr, len)
>      int    file;
>      char * ptr;
>      int    len;
> {
>   asm ("ldi:8 %0, r0" :: "i" (SYS_read) : "r0");
>   asm ("int   #10");
>
>   return;
> }

Note the lack of a value on the "return" statement.  The assumption is that the
interrupt handler implementing syscalls will put the return value into the
proper register, so falling off the end of the C function or returning with no
value works in the expected way.  It's not good code, but it probably works.

Working from that assumption I decided to just use a pragma to disable the
upgraded diagnostic from GCC -- essentially preserving existing behavior.

This is the only fr30 specific issue that needs to be resolved and the only
issue (so far) I've seen of this specific nature.

Hans-Peter Nilsson 3bafe2fae7 newlib cris: Fix compilation warnings that recent gcc treats as errors
For the newlib part, warnings are all from lack of sync between
libc/machine/cris/sys/signal.h and libc/include/sys/signal.h.  This
commit gets them sufficiently in sync again, functionality-wise and
declaration-wise.  Still, nothing is declared that isn't supported at
the system level (i.e. in libgloss system calls and handled by the
CRIS simulator in the gdb project).

Hans-Peter Nilsson 7cce4cdd6e libgloss/cris: Make C declarations present and match them
This is the libgloss part.
Recently, there was a change in gcc such that implicit function
declarations and type mismatches are now errors, no longer just
warnings.  Fix by adding and correcting declarations warned about;
including the right header or adding a declaration (for "main" in
lcrt0.c) and adjust to those types as necessary.
