547b3a3b01 Changes to existing files to enable building AARCH64 userland. 
evbarm64-el
This is clang only.  While gcc4.8 supports aarch64, no netbsd support has
been written for aarch64 with gcc4.8.

1751681322 Fix a cast from the lint cleanup that made small exponents (i.e. values < 1) 
sign extend wrong and overflow, causing an underflow in all 128 bit sqrt
calculations.

71f1d3fc0f For arm, add -fno-tree-vrp to COPTS when compiling softfloat.c. 
Without -fno-tree-vrp, -INF + -INF returns 0 by adddf3.
Fixes PR#46953.

fba9f55f04 ARM EABI (AAPCS) uses different names for the softfloat routines that 
the normal GCC ones.  So after we redefine softfloat's to be what (old) GCC
wants, we redefined the old GCC names to what ARM EABI want (but only if we
are using ARM EABI).  We do this for routines not compiled by softfloat so
can just have these redefinitions in one place.

598174eb2b Apply local namespace protection equivalent to the weak alias done 
in softfloat-for-gcc.h, which we can't include here, to move
"float_exception_mask" into implementation namespace.

then append them to ${SRCS}.  Those will be used to generate quad / softfloat
symbol lists.

negative overflow.

5265977a9e When converting long double values to integer types, explicitly use the 
"round to zero" variants of the softfloat conversion functions.
Add a variant to convert long double to unsigned long - the "to long"
variant checked for overflows that do not apply to unsigned results.
This fixes the regress/lib/libc/convfp tests for sparc64.

8a1eb34d66 Add support to build the mac68k port with soft-float enabled (i.e., setting 
MKSOFTFLOAT=yes).  The main purpose of this feature is to let NetBSD work
in machines with the 68040LC chip (those that have the FPU bug).

All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>,
with some very minor changes by me; the patches were being posted to the
port-mac68k mailing list.  It has been tested for a long time by several
users, including me.

I have just verified that regular releases, as well as soft-float ones,
continue to build.

There have been no objections to this patch since I asked for them in July
in the port-mac68k list.

936b7f4cf8 Import the 32-bit version of SoftFloat 2a and separate it and the 64-bit 
version into different directories.  Which version a given port uses is
controlled by the SOFTFLOAT_BITS make variable.  This is set to 64 (which
uses the same code we had before) by default.  32-bit platforms that don't
need extended precision support might get better performance by using 32.

Set the ARM port to use the 32-bit version of SoftFloat, since this is more
than a factor of two faster than the 64-bit version.  This should get the
floating-point performance back to what it was in 1.5.

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.

9ec812439b In float*_round_to_int(), where we have switches over rounding modes, make 
sure that all the modes are mentioned, if only with a "break;".  This
ensures GCC doesn't whinge at us on ports which use an enum for fp_rnd.

251de84ccc Consistently declare the types of float_rounding_mode and float_exception_flags 
as fp_rnd and fp_except respectively.
