Bug ID: 31270
Summary: Unknown instructions in the instruction table (RISCV
assembler
Product: binutils
Version: 2.16
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: jacob at jacob dot remcomp.fr
Target Milestone: ---
RISCV assembler
The instructions th.ipop and th.ipush are not documented in the T-Head
documentation and nowhere in the net.
I do not know what it is, and would like to know why it appears in the
instruction table. When I assemble this, it produces 0x50000b
My T-Head machine doesn't boot (corrupt disk) so I can't test this. What do
this instructions do?
These are the entries in the instruction table:
/* Vendor-specific (T-Head) XTheadInt instructions. */
{"th.ipop",0,INSN_CLASS_XTHEADINT,"",MATCH_TH_IPOP,MASK_TH_IPOP,match_opcode,0},
{"th.ipush",0,INSN_CLASS_XTHEADINT,"",MATCH_TH_IPUSH,MASK_TH_IPUSH,match_opcode,0},
Thanks in advance
