[PATCH 0/7] Add support for extension specific disas


From: Weiwei Li
Subject: [PATCH 0/7] Add support for extension specific disas
Date: Fri, 19 May 2023 10:19:19 +0800

Some extensions have conflict encodings, such as
 * Z*inx reuse the same encodings as normal float point extensions.
 * Zcm* reuse the some encodings of Zcd.
 * Custom extensions from different vendors may share the same encodings.
To resolve this problem, this patchset tries to pass RISCVCPUConfig as 
disasemble_info.target_info to support extension specific disas, which means 
that the disas for this extensions is supported only when the related extension 
is supported.
This patchset also fixes some style problems in disas/riscv.c.

The port is available here:
https://github.com/plctlab/plct-qemu/tree/plct-disas-upstream

Weiwei Li (7):
  disas: Change type of disassemble_info.target_info to pointer
  target/riscv: Pass RISCVCPUConfig as target_info to disassemble_info
