The roundAndPackFloat16 function should return a float16 value, not a
float32 one. Fix that.
Backports commit 7ceac86f49b564954f5bde477c4281f407be1399 from qemu
Replace the int8 softfloat-specific typedef with int8_t.
This change was made with
find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint8\b/int8_t/g'
together with manual removal of the typedef definition, and
manual undoing of various mis-hits.
Backports commit 8f506c709adb7d3bed4ebefefe9487c156192a64 from qemu
Replace the uint32 softfloat-specific typedef with uint32_t.
This change was made with
find include hw fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint32\b/uint32_t/g'
together with manual removal of the typedef definition,
manual undoing of various mis-hits, and another couple of
fixes found via test compilation.
All the uses in hw/ were using the wrong type by mistake.
Backports commit 3a87d00910ef64a2eece4aad25d96ea10683fc5c from qemu
Replace the int32 softfloat-specific typedef with int32_t.
This change was made with
find hw include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\bint32\b/int32_t/g'
together with manual removal of the typedef definition, and
manual undoing of some mis-hits where macro arguments were
being used for token pasting rather than as a type.
The uses in hw/ipmi/ should not have been using this type at all.
Backports commit f4014512cda682a9d0c75310d278d7ae96b0505c from qemu
Replace the uint64 softfloat-specific typedef with uint64_t.
This change was made with
find include fpu target-* -name '*.[ch]' | xargs sed -i -e 's/\buint64\b/uint64_t/g'
together with manual removal of the typedef definition, and
manual undoing of some mis-hits where macro arguments were
being used for token pasting rather than as a type.
Note that the target-mips/kvm.c and target-s390x/kvm.c changes are fixing
code that should not have been using the uint64 type in the first place.

Backports commit f42c222482b651400f0fa417eb174da1c9502c1c from qemu
The code in the softfloat source files is under a mixture of
licenses: the original code and many changes from QEMU contributors
are under the base SoftFloat-2a license; changes from Stefan Weil
and RedHat employees are GPLv2-or-later; changes from Fabrice Bellard
are under the BSD license. Clarify this in the comments at the
top of each affected source file, including a statement about
the assumed licensing for future contributions, so we don't need
to remember to ask patch submitters explicitly to pick a license.
Backports commit 16017c48547960539fcadb1f91d252124f442482 from qemu
Revert the parts of commits b645bb4885 and 5a6932d51d which are still
in the codebase and under a SoftFloat-2b license.
Reimplement support for architectures where the most significant bit
in the mantissa is 1 for a signaling NaN rather than a quiet NaN,
by adding handling for SNAN_BIT_IS_ONE being set to the functions
which test values for NaN-ness.
This includes restoring the bugfixes lost in the reversion where
some of the float*_is_quiet_nan() functions were returning true
for both signaling and quiet NaNs.
[This is a mechanical squashing together of two separate "revert"
and "reimplement" patches.]
Backports commit 332d5849708d11b835e0b36f4e26e8b36bfb3f5a from qemu
Revert the remaining portions of commits 75d62a5856 and 3430b0be36f
which are under a SoftFloat-2b license, ie the functions
uint64_to_float32() and uint64_to_float64(). (The float64_to_uint64()
and float64_to_uint64_round_to_zero() functions were completely
rewritten in commits fb3ea83aa and 0a87a3107d so can stay.)
Reimplement from scratch the uint64_to_float64() and uint64_to_float32()
conversion functions.

and "reimplement" patches.]
Backports commit 6bb8e0f130bd4aecfe835a0caa94390fa2235fde from qemu
This commit applies the changes to master which correspond to
replacing commit 158142c2c2df with a set of changes made by:
* taking the SoftFloat-2a release
* mechanically transforming the block comment style
* reapplying Fabrice's original changes from 158142c2c2df
This commit was created by:
diff -u 158142c2c2df import-sf-2a
patch -p1 --fuzz 10 <../relicense-patch.txt
(where import-sf-2a is the branch resulting from the changes above).
