;; IBM Z: Add risbgz and risbgnz extended mnemonics
|
||
|
|
;; (Andreas Krebbel, RHBZ 2012818)
|
||
|
|
|
||
|
|
These two extended mnemonics are documented in the Principles of
|
||
|
|
Operations manual but currently not supported by Binutils. They
|
||
|
|
provide aliases for already supported instructions with the zero flag
|
||
|
|
being set. The flag otherwise is mingled into one of the immediate
|
||
|
|
operands what makes asm code much harder to read.

(INSTR_RIE_RRUUU2, MASK_RIE_RRUUU2): New instruction format and
