softfloat in the kernel
I ported the berkeley-softfloat-3 library to run in the NetBSD kernel.
The only difference is that we need to include different headers than the userspace ones.
I intend to merge this into the NetBSD distribution, but would you accept the patch to make berkeley-softloat-3 buildable in such environment out of the box upstream?
Another approach would be to rely on GCC/Clang defines and redefine all the *int* types from the builtin types, such as __INT_FAST64_TYPE__. It would make berkeley-softfloat-3 fully standalone.
I prefer to avoid downstream patches if possible.
conflicts with gcc's <arm_neon.h>
<arm_neon.h> is defined by a spec that ARM releases, and implemented by compilers. It is not a "real" header file. This happen with either included first.

Perhaps softfloat does not work with <arm_neon.h>, in which case a preprocessor #error should give a more helpful error.
Future direction of SoftFloat and its development model
The QEMU project makes extensive use of SoftFloat to model floating point instructions. The source in QEMU's tree is based on SoftFloat2a due to later incompatibilities in the licensing. It has also seen a number of additions over time including specialisation for the various architectures we emulate. Perhaps the biggest one being augmenting the API to pass *float_status to the various operations. This needed to be done as the CPUs we emulate often have different FPU contexts so the floating point flags shouldn't interfere with each other.
As time has moved on and more recent processor revisions require additional features from later revisions of IEE754 we are faced with a dilemma of how to move forward. We can either keep adding features to our copy of 2a or instead port our code to use 3c and it track its future development. However given our extensive changes this doesn't make sense if our internal copy is going to have to be significantly modified and diverge again from the upstream. So this leads to a couple of questions:
- What are the development goals of SoftFloat?
- why was it originally written and who are its target users?
- Is SoftFloat in active development?
- under history it is mentioned UC Berkley funded v3. Is this an ongoing commitment or was there a goal in mind?
- is the project interested in taking patches from the wider community?
- What is SoftFloat's development model?
- The homepage just suggests mailing John directly but there is this repository. Is future development now here or is this just a fork for the Berkley team?
Add ARM support
f32_div and f32_sqrt
I could hardly figure out how does f32_div and f32_sqrt work,
especially the two magic functions "softfloat_approxRecip32_1" and "softfloat_apprroxxRecipSqrt32_1"
If there is any paper or website help me learn more details?
f64_mulAdd propagate non-default NaN based on Linux-ARM-VFPv2-GCC
Dear developer,
I ported the berkeley-softfloat-3 library which is built from berkeley-softfloat-3/build/Linux-ARM-VFPv2-GCC/Makefile.
I found that there may be a mistake when I using the function, f64_mulAdd(op2, op1, addend), and give the operand as following
- op1 = Denormal value
- op2 = QNaN
- addend = QNaN
The arithmatic result is different between berkeley-softfloat-3 and pseudo code from ARM spec:
- berkeley-softfloat-3: return result is equal to op2
- pseudo code from ARM spec: return result is equal to addend
Please help me to confirm whether berkeley-softfloat-3 library is wrong at here or something missing in my thinking.
The following contents are my investigation:
- The softfloat result will be the same as op2 based on following code from source/s_mulAddF64.c and source/ARM-VFPv2/s_propagateNaNF64UI.c. (※ uiA -> op2, uiB -> op1, uiC -> addend)
- I take the reference to Arm Architecture Reference Manual for A-profile architecture, the result should be the same as addend. The following is its related pseudo code with red mark. (※ I set fpcr's all bits are 0)
Many thanks.
inline problems at -O0
I wrote Rust bindings to softfloat (https://crates.io/crates/softfloat-sys), however I ran into linking problems since a lot of internal functions are declared inline but there is no out-of-line version of them. As a workaround, I had to make -O1 the minimum optimization level.
Note that I am not using softfloat's makefiles, I instead wrote the build.rs build script based on them.
s_roundPackToF32.c rounding to odd
Hi,
s_roundPackToF32.c, line 96 implement rounding to odd as following:
96 if ( roundingMode == softfloat_round_odd ) {
97 sig |= 1;
Does this means rod always or the fraction part bit0 to 1'b1?
The correct behavior of rod suppose to be frac round up only:
- round > 0.5
- if 0.5 & (guard bit == 0)
Kou
extra semicolon in if causing compile fail in "source/RISCV/s_propagateNaNF128M.c"
behavior of "tininess after rounding" is different in old version
for softfloat-3e
Errors found in f32_mul, rounding near_even:
+01.000000 +7E.7FFFFF => +01.000000 ....x expected +01.000000 ...ux
+01.000000 -7E.7FFFFF => -01.000000 ....x expected -01.000000 ...ux
this case is tricky: the product is a normal number after rounding.
in the function

handling tininess part
3e: (line 69 to 80)
if ( exp < 0 ) {
/*----------------------------------------------------------------
----------------------------------------------------------------/
isTiny =
(softfloat_detectTininess == softfloat_tininess_beforeRounding)
|| (exp < -1) || (sig + roundIncrement < 0x80000000);
sig = softfloat_shiftRightJam32( sig, -exp );
exp = 0;
roundBits = sig & 0x7F;
if ( isTiny && roundBits ) {
softfloat_raiseFlags( softfloat_flag_underflow );
}
old 3:
if ( exp < 0 ) {
sig = softfloat_shiftRightJam32( sig, -exp );
isTiny =
(softfloat_detectTininess
== softfloat_tininess_beforeRounding)
|| (exp < -1)
|| (sig + roundIncrement < 0x40000000);
exp = 0;
roundBits = sig & 0x7F;
if ( isTiny && roundBits ) {
softfloat_raiseFlags( softfloat_flag_underflow );
}
the changed part will not affect the choice of tininessbefore
but cause flags different in tininessafter
Add clang support
Please add support for building with the Clang compiler. Thanks!
Consider adding bfloat16 support.
Arm v8.6 and RISC-V extensions Zfbfmin, Zvfbfmin, and Zvfbfwma add support for bfloat16 instructions. Modeling the bfloat16 type would be beneficial in emulating these extensions.
Consider fixing compiler warnings and adding -Wall -Wextra -Weverything
Please consider fixing the following compiler warnings from GCC and Clang. Most of these can probably be fixed by adding explicit type casts. It would add credibility to the project if these warnings were fixed.

Sync with softfloat from spike
Spike seems to use a slighty modified version of softfloat 3d with some additions that are not present in this 3e version.
Would it be possible to sync them up again?
In particular I'm personally missing in this 3e release:
f32_rsqrte7f64_rsqrte7f32_recip7f64_recip7
I'm happy to create a pull request for this but I first wanted to make sure I didn't overlook something...
E.g. there is a valid reason the versions are incompatible currently.
Or the functions I'm looking for exist but under a different name.
