NetBSD 10.x with FPU_emulation on i486sx

This retro-computing project restores support for x87 floating-point unit (FPU) emulation in the NetBSD kernel,
targeting legacy 486SX-class processors without hardware FPUs. It brings back the original MATH_EMULATE option into
NetBSD 10.x and beyond, as well as reverts and reworks the changes introduced in
commit dfe83e0, which removed FPU
emulation support from the kernel.

This project is a work in progress and may contain bugs or incomplete functionality. Use at your own risk.
The author is not responsible for any issues caused by its use.

  • fyl2x seems to work properly on FPU, but when executed from libc, log functions bring incorrect results
  • Some operations have hard-to-detect issues with precision

x87 FPU Emulated Instructions

🧠 Control & Initialization

Instruction Status Description Opcode Example
fninit ✅ OK Initialize FPU 9B DB E3 fninit

Instruction Status Description Opcode Example
fld ✅ OK Load floating-point value D9 /0 fld st(1)
fldt ✅ OK Load 80-bit extended precision DB /5 fldt [mem]
filds ✅ OK Load integer (short) DB /0 filds [mem]
fildl ✅ OK Load long integer DB /A fildl [mem]

📤 Store from FPU Stack

Instruction Status Description Opcode Example
fstps ✅ OK Store and pop single precision D9 /3 fstps [mem]
fstpt ✅ OK Store 80-bit extended precision & pop DB /7 fstpt [mem]

➕➖✖️➗ Arithmetic Operations

Instruction Status Description Opcode Example
fadd ✅ OK Add floating-point values D8 /0 fadd st(1), st
faddl ✅ OK Add long double from memory DA /0 faddl [mem]
fsub ✅ OK Subtract floating-point values D8 /4 fsub st(1), st
fsubp ✅ OK Subtract with pop DE /5 fsubp st(1), st(0)
fmul ✅ OK Multiply floating-point values D8 /1 fmul st(1), st
fdiv ✅ OK Divide floating-point values D8 /6 fdiv st(1), st
fdivp ✅ OK Divide with pop DE /7 fdivp st(1), st(0)
fscale ✅ OK Scale ST(0) by ST(1) D9 FD fscale

Instruction Status Description Opcode Example
fcom ✅ OK Compare floating-point values D8 /2 fcom st(1)
fucom ✅ OK Unordered compare ST(0) with ST(i) DD E0+i fucom st(1)
fucomp ✅ OK Unordered compare and pop DD E8+i fucomp st(1)
ftst ✅ OK Compare ST(0) with 0.0 D9 E4 ftst

🔁 Stack Manipulation & Modification

Instruction Status Description Opcode Example
fxch ✅ OK Exchange ST(0) with ST(i) D9 C8+i fxch st(1)
fchs ✅ OK Change sign of ST(0) D9 E0 fchs
fabs ✅ OK Absolute value of ST(0) D9 E1 fabs
frndint ✅ OK Round ST(0) to integer D9 FC frndint

📈 Logarithmic and Special Math Operations

Instruction Status Description Opcode Example
fyl2x ⏳ TBD Compute y × log₂(x) (ST(1) × log₂(ST(0))) and pop D9 F1 fyl2x
fyl2xp1 ❌ N/A Compute y × log₂(x+1) and pop D9 F9 fyl2xp1
fxtract ❌ N/A Extract: ST(0) → ST = significand, ST+1 = exponent D9 F4 fxtract
f2xm1 ✅ OK Compute 2^x – 1 for ST(0) D9 F0 f2xm1
fpatan ❌ N/A Compute arctangent(ST(1)/ST(0)) and pop D9 F3 fpatan
fsqrt ❌ N/A Compute square root of ST(0) D9 FA fsqrt

$ cd /usr/src/sys/arch/i386/conf/
$ vi GENERIC_TINY_486SX# or GENERIC_PS2TINY_486SX or create your own kernel configuration with "options MATH_EMULATE"
$ config GENERIC_TINY_486SX
$ cd ../compile/GENERIC_TINY_486SX
$ make depend
$ make

# If everythig good, install the new kernel under root:
# mv /netbsd /netbsd.old
# mv netbsd /

Check Releases for the compiled netbsd kernel with FPU-emulation
as well, as the drive image
