2015-01-29softfloat: Clarify license statusPeter Maydell1-1/+47
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.

2015-01-29softfloat: Apply patch corresponding to rebasing to softfloat-2aPeter Maydell1-20/+18
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).

2014-06-23fpu: softfloat: drop INLINE macroLuiz Capitulino1-19/+19
This commit expands all uses of the INLINE macro and drop it. The reason for this is to avoid clashes with external libraries with bad name conventions and also because renaming keywords is not a good practice. PS: I'm fine with this change to be licensed under softfloat-2a or softfloat-2b. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2013-06-10softfloat: Fix shift128Right for shift counts 64..127Peter Maydell1-1/+1
shift128Right would give the wrong result for a shift count between 64 and 127. This was never noticed because all of our uses of this function are guaranteed not to use shift counts in this range.

2011-04-17softfloat: use GCC builtins to count the leading zerosAurelien Jarno1-2/+27
Softfloat has its own implementation to count the leading zeros. However a lot of architectures have either a dedicated instruction or an optimized to do that. When using GCC >= 3.4, this patch uses GCC builtins instead of the handcoded implementation. Note that I amware that QEMU_GNUC_PREREQ is defined in osdep.h and that clz32() and clz64() are defined in host-utils.h, but I think it is better to keep the softfloat implementation self contained.

2011-03-21softfloat: Drop [s]bits{8, 16, 32, 64} types in favor of [u]int{8, 16, 32, 64}_tAndreas Färber1-91/+91
They are defined with the same semantics as the POSIX types, so prefer those for consistency. Suggested by Peter Maydell.

2011-03-21softfloat: Prepend QEMU-style header with derivation noticeAndreas Färber1-0/+5
The SoftFloat license requires "prominent notice that the work is derivative". Having added features like improved 16-bit support for arm already, add such a notice to the sources. softfloat-native.[ch] are not under the SoftFloat license and thus are not changed.
