Functions
bfc_error_t	bfc_parse_jump_table (int64_t **jump_table, bfc_token_stream_t const *const tok_stream)
	Validates nested brackets and fills a bidirectional matching-index table.
void	bfc_jump_table_destroy (int64_t **pjump_table)
	Releases the matching-index table and nulls the caller pointer.

Detailed Description

Bracket-matching validation pass.

Uses a stack of opening-bracket indices to build a bidirectional jump table and produce source-aware bracket errors.

Releases the matching-index table and nulls the caller pointer.

Releases a jump table and nulls the caller pointer.

Releases the matching-index table and nulls the caller pointer.

bfc_parse_jump_table()

bfc_error_t bfc_parse_jump_table	(	int64_t **	jump_table,
		bfc_token_stream_t const *const	tok_stream )

Validates nested brackets and fills a bidirectional matching-index table.

Validates loop delimiters and builds matching bracket indices.

Validates nested brackets and fills a bidirectional matching-index table.

Parameters

[out]	jump_table	Receives an allocated table indexed by token position.
[in]	tok_stream	Token stream to validate.

Returns

BFC_ERR_OK on success; otherwise an allocation or bracket error.
