Log:
simplify-rtx: Add missing line for previous commit (PR78583)
The comment for the added case to simplify_truncation reads
/* Turn (truncate:M1 (*_extract:M2 (reg:M2) (len) (pos))) into
(*_extract:M1 (truncate:M1 (reg:M2)) (len) (pos')) if possible without
changing len. */
but I forgot to check the two modes M2 are actually the same.
PR rtl-optimization/78583
* simplify-rtx.c (simplify_truncation): Add check missing from the
previous commit.
