MIPS: math-emu: Unify ieee754dp_m{add,sub}f

2016-05-13T12:02:22+00:00

The code for emulating MIPSr6 madd.d & msub.d instructions has previously been implemented as 2 different functions, namely ieee754dp_maddf & ieee754dp_msubf. The difference in behaviour of these 2 instructions is merely the sign of the product, so we can easily share the code implementing them. Do this for the double precision variant, removing the original ieee754dp_msubf in favor of reusing the code from ieee754dp_maddf.

MIPS: math-emu: Unify ieee754sp_m{add,sub}f

2016-05-13T12:02:22+00:00

The code for emulating MIPSr6 madd.s & msub.s instructions has previously been implemented as 2 different functions, namely ieee754sp_maddf & ieee754sp_msubf. The difference in behaviour of these 2 instructions is merely the sign of the product, so we can easily share the code implementing them. Do this for the single precision variant, removing the original ieee754sp_msubf in favor of reusing the code from ieee754sp_maddf.

MIPS: math-emu: Add support for the MIPS R6 MAX{, A} FPU instruction

2015-09-03T10:08:14+00:00

MIPS R6 introduced the following instruction: Scalar Floating-Point Maximum and Scalar Floating-Point argument with Maximum Absolute Value MAX.fmt writes the maximum value of the inputs fs and ft to the destination fd. MAXA.fmt takes input arguments fs and ft and writes the argument with the maximum absolute value to the destination fd.

MIPS: math-emu: Add support for the MIPS R6 MIN{, A} FPU instruction

2015-09-03T10:08:14+00:00

MIPS R6 introduced the following instruction: Scalar Floating-Point Minimum and Scalar Floating-Point argument with Minimum Absolute Value MIN.fmt writes the minimum value of the inputs fs and ft to the destination fd. MINA.fmt takes input arguments fs and ft and writes the argument with the minimum absolute value to the destination fd.

MIPS: math-emu: Add support for the MIPS R6 CLASS FPU instruction

2015-09-03T10:08:14+00:00

MIPS R6 introduced the following instruction: Stores in fd a bit mask reflecting the floating-point class of the floating point scalar value fs.

MIPS: math-emu: Add support for the MIPS R6 MSUBF FPU instruction

2015-09-03T10:08:13+00:00

MIPS R6 introduced the following instruction: Floating Point Fused Multiply Subtract: MSUBF.fmt To perform a fused multiply-subtract of FP values.

MIPS: math-emu: Move long fixed-point support into an `ar' library

2015-04-07T23:10:12+00:00

Complement 593d33fe [MIPS: math-emu: Move various objects into an ar library.] and also move sp_tlong.o, sp_flong.o, dp_tlong.o, and dp_flong.o into an `ar' library. These objects implement long fixed-point format support that can be omitted from MIPS I, MIPS II and MIPS32r1 configurations. Signed-off-by: Maciej W.
