Loads a floating-point, single-precision number that has been converted to a floating-point, double-precision number into a floating-point register.
| lfsx | FRT,RA,RB |
The lfsx instruction converts a floating-point, single-precision word in storage addressed by the effective address (EA) to floating-point, double-precision word and loads the result into floating-point register (FPR) FRT.
If general-purpose register (GPR) RA is not 0, the EA is the sum of the contents of GPR RA and GPR RB. If RA is 0, then the EA is the contents of GPR RB.
The lfsx instruction has one syntax form and does not affect the Floating-Point Status and Control Register.
| FRT | Specifies target floating-point register where data is stored. |
| RA | Specifies source general-purpose register for EA calculation. |
| RB | Specifies source general-purpose register for EA calculation. |
The following code loads the single-precision contents of storage into FPR 6:
storage: .float 0x1. # Assume GPR 4 contains the address of storage. lfsx 6,0,4 # FPR 6 now contains 0x3FF0 0000 0000 0000.
