Made psq_l variants inside of psq_l. Added psq_st and variants
psq_l frD, d(rA), W, I
This instruction dequantizes values from the memory address in '''d'''+('''rA'''|0) and puts them into PS0 and PS1 in '''frD'''. If '''W''' is 1, however, it only dequantizes one number, and places that into PS0. PS1 is loaded with 1.0 always when '''W''' is 1. '''I''' specifies the GQR to use for dequantization parameters. The two numbers read from the memory are directly after each other, regardless of size (for example, if the GQR specified to load as a u16, you would have '''d'''+('''rA'''|0) point to a two-element array of u16s)
===== psq_lx =====
psq_lx frD, rA, rB, W, I
This instruction acts exactly like psq_l, except instead of ('''rA''') being offset by '''d''', it is offset by ('''rB''').
===== psq_lu =====
psq_lu frD, d(rA), W, I
This instruction acts exactly like psq_l, except '''rA''' cannot be 0, and '''d'''+('''rA''') is placed back into '''rA'''.
===== psq_lux =====
psq_lux frD, rA, rB, W, I
This instruction acts exactly like psq_lx, except '''rA''' cannot be 0, and '''d'''+('''rA''') is placed back into '''rA'''.
 
=== psq_st ===
psq_st frD, d(rA), W, I
This instruction quantizes values from the Paired Singles in '''frD''' and places them in the memory address in '''d'''+('''rA'''|0). If '''W''' is 1, however, it only quantizes PS0. '''I''' specifies the GQR to use for dequantization parameters. The two numbers written to memory are directly after each other, regardless of size (for example, if the GQR specified to store as a u16, '''d'''+('''rA'''|0) would be treated as a two-element array of u16s)
===== psq_stx =====
psq_stx frD, rA, rB, W, I
This instruction acts exactly like psq_st, except instead of ('''rA''') being offset by '''d''', it is offset by ('''rB''').
===== psq_stu =====
psq_stu frD, d(rA), W, I
This instruction acts exactly like psq_st, except '''rA''' cannot be 0, and '''d'''+('''rA''') is placed back into '''rA'''.
===== psq_stux =====
psq_stux frD, rA, rB, W, I
This instruction acts exactly like psq_stx, except '''rA''' cannot be 0, and '''d'''+('''rA''') is placed back into '''rA'''.
