s390 — Proposed
s390: Add test for .insn pseudo-mnemonic rrs
Adds gas test cases for the .insn rrs pseudo-mnemonic on s390.
This patch adds a new test case for the .insn rrs pseudo-mnemonic to the s390 GNU Assembler (gas) test suite. The changes update the zarch-operands disassembly and assembly files to include specific examples for this mnemonic, ensuring proper assembly and disassembly behavior.
In the Thread
- proposer
Submits patches to add test cases for the .insn rrs pseudo-mnemonic in the s390 gas assembler.
“gas/testsuite/ * gas/s390/zarch-operands.d: Add test for .insn rrs. * gas/s390/zarch-operands.s: Likewise.”
In Details
This patch adds test cases for the '.insn rrs' pseudo-mnemonic in the s390 GNU Assembler (gas). It extends the zarch-operands test suite by adding definitions and expected outputs for this specific instruction format, ensuring correct assembly and disassembly.
For Context
- .insn
- A GNU Assembler directive that allows embedding raw machine instructions or pseudo-mnemonics, useful for testing or specific instruction generation.
- pseudo-mnemonic
- An assembly language construct that resembles a machine instruction but is processed by the assembler to generate one or more actual machine instructions or to represent a complex instruction format.
