Loads a floating-point, single-precision number that has been converted to a floating-point, double-precision number into a floating-point register.
| lfs | FRT,D(RA) |
The lfs instruction converts a floating-point, single-precision word in storage addressed by the effective address (EA) to a floating-point, double-precision word and loads the result into floating-point register (FPR) FRT.
If RA is not 0, the EA is the sum of the contents of GPR RA and D, a 16-bit, signed two's complement integer sign-extended to 32 bits. If RA is 0, then the EA is D.
The lfs instruction has one syntax form and does not affect the Floating-Point Status and Control Register or Condition Register Field 0.
The following code loads the single-precision contents of storage into FPR 6:
.csect data[rw] storage: .float 0x1 # Assume GPR 5 contains the address csect data[rw]. .csect text[pr] lfs 6,storage(5) # FPR 6 now contains 0x3FF0 0000 0000 0000.
