From e75cfa9f0f81f70389b6d81d22b664c37f2403db Mon Sep 17 00:00:00 2001 From: Jens Remus Date: Mon, 9 Sep 2024 17:05:27 +0200 Subject: [PATCH] s390: Document syntax to omit base register operand Document the s390-specific assembler syntax introduced by commit aacf780bca29 ("s390: Allow to explicitly omit base register operand in assembly") to omit the base register operand B in D(X,B) and D(L,B) by coding D(X,) and D(L,). While at it document the alternative syntax to omit the index register operand X in D(X,B) by coding D(,B) instead of D(B). gas/ * doc/c-s390.texi (s390 Operands): Document syntax to omit base register operand.
