[Bug Report] Duplicated 0xFC instructions in the "Index of Instructions" page

[asukakenji]

In https://webassembly.github.io/spec/core/appendix/index-instructions.html, we can see that the 0xFC instructions with sub opcode 0 to 7 are duplicated.

As we can see in the source code:

spec/document/core/appendix/gen-index-instructions.py

Lines 334 to 341 in 9849315

	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F32\K{\_s}', r'\hex{FC}~~0', r'[\F32] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F32\K{\_u}', r'\hex{FC}~~1', r'[\F32] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),
	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F64\K{\_s}', r'\hex{FC}~~2', r'[\F64] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F64\K{\_u}', r'\hex{FC}~~3', r'[\F64] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F32\K{\_s}', r'\hex{FC}~~4', r'[\F32] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F32\K{\_u}', r'\hex{FC}~~5', r'[\F32] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),
	Instruction(r'\I64.\TRUNC\K{\_sat}\_\F64\K{\_s}', r'\hex{FC}~~6', r'[\F64] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F64\K{\_u}', r'\hex{FC}~~7', r'[\F64] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),

is a duplicate of:

spec/document/core/appendix/gen-index-instructions.py

Lines 316 to 323 in 9849315

	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F32\K{\_s}', r'\hex{FC}~\hex{00}', r'[\F32] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F32\K{\_u}', r'\hex{FC}~\hex{01}', r'[\F32] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),
	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F64\K{\_s}', r'\hex{FC}~\hex{02}', r'[\F64] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I32.\TRUNC\K{\_sat\_}\F64\K{\_u}', r'\hex{FC}~\hex{03}', r'[\F64] \to [\I32]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F32\K{\_s}', r'\hex{FC}~\hex{04}', r'[\F32] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F32\K{\_u}', r'\hex{FC}~\hex{05}', r'[\F32] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F64\K{\_s}', r'\hex{FC}~\hex{06}', r'[\F64] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_s'),
	Instruction(r'\I64.\TRUNC\K{\_sat\_}\F64\K{\_u}', r'\hex{FC}~\hex{07}', r'[\F64] \to [\I64]', r'valid-cvtop', r'exec-cvtop', r'op-trunc_sat_u'),

(the only difference is that the L316-L323 use hexadecimal while L334-L341 use decimal) and thus lines L334-L341 need to be deleted.

Thanks, probably a merge artefact. See #1402 for a fix.
