lukem a93ea220fc Rework how dependency generation is performed:
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
  This is a change of behaviour.  If a Makefile wants the clean semantics
  it must specifically append to CLEANFILES.
  Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
  that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d  depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

kleink db907cb577 Rename ieee754_function.c to function_ieee754.c, following the convention
used in exec_format.c, loadfile_format.c, subsys_machdep.c etc.
Per discussion with Christos.

martin cf437d291f Make _Qp_qtoui return the right value for inputs that do not fit into
an int value, but are valid unsigned ints. This should fix PR 21414.
The same problem exists for _Qp_qtoux, but there is no similar trivial
solution to that (I could think of).

thorpej c061e6bf8b Enable the libc-provided signal trampoline. The old __sigaction14
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).

No shared library version change is necessary; no new symbols
are exposed outside of libc.

thorpej 86223838f0 Also need <machine/fsr.h> and <machine/psl.h>. 2002-07-10 03:27:23 +00:00
thorpej 8aa4d3caec New __sigaction14() system call stub which registers the signal
trampoline, and the signal trampolines themselves.

NOTE: These are not yet enabled; they will be enabled after further
testing on more architectures.

wiz 92d8b1e9fa Revert previous: .S files are currently compiled with -traditional-cpp,

bjh21 010758bf16 Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.

simonb 2d8577fb83 Clean up some rampant code duplication wrt ieee number handling:
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).
2002-02-19 13:08:12 +00:00
jmc 4b4c3144ba Enable the _Qp* routines to be built always and allow full softfloat to be
pulled in if MKSOFTFLOAT gets enabled.
2002-02-05 07:54:01 +00:00
jmc d9c86555ad Add softfloat and quad softfloat setup for sparc64 (thanks to Andrey Petrov
for most of this. I just integrated the build).

This adds proper functions for the _Qp* parts of the sparc64 ABI (which
handle quad softfloat). The routines work but need additional testing.
However if the compiler calls these currently bad things (core dumps)
will happen as gcc 2.95.3 generates bad calls for these.

Until that problem is fixed in the toolchain -msoft-quad-float cannot be
enabled as the default option for all builds (but the routines need to be
in libc as libgcc contains some references to these and anything including
it via --whole-archive will need the symbols to at least resolve).

tv 26375a1710 Remove -Wa,-Av9a hack from <sys.mk> and relegate it to the places that need
it (kernel and libc).

The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format.  "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.

mycroft c54917029b Make __dtoul() actually DTRT. The calling convention was totally wrong, and

mycroft e740400671 Just use a store/load pair to get the pattern into the FP reg. This eliminates
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.
