- {cheri_int_mode_name} Description
-
Standard floating point stack pointer relative load instructions, authorized by the capability in [ddc].
|
Note
|
These instructions are available in RV64 {cheri_int_mode_name} only. In RV64 {cheri_cap_mode_name} they are remapped to [C.LC]/[C.LCSP]. |
|
Note
|
These encodings may be remapped by future code-size Zcm standard extensions, similar to [Zcmp] and [Zcmt]. The rule is that in RV64 {cheri_cap_mode_name} they are always remapped to [C.SC]/[C.SCSP]. |
- Prerequisites for {cheri_cap_mode_name} (RV32 only)
