Subzero, MIPS32: Floating point support in ELF output
Patch implements improvements and instruction encodings for many COP1 instructions for handling floating point values.
Patch covers load, store, basic arithmetic, data movement for FPR<->FPR, GPR<->FPR, FPR<->GPR, and format conversion instructinos.
Added instruction encodings:
Load: lb, lh, lwc1, ldc1
Store: sb, sh, swc1, sdc1
FP arith: abs_d, abs_s, add_d, add_s, div_d, div_s, mul_d, mul_s, sqrt_d, sqrt_s, sub_d, sub_s
FP movs: mfc1, mov_d, mov_s, movn_d, movn_s, movz_d, movz_s, mtc1
Conversion: cvt_d_l, cvt_d_s, cvt_d_w, cvt_s_d, cvt_s_l, cvt_s_w, trunc_l_d, trunc_l_s, trunc_w_d, trunc_w_s
