hi @PhilippvK
> * While the P extension seems to be somehow supported (intrinsics are
available) I could not link a 32bit program (`-march=rv32gcp -mabi=ilp32d`)
using these intrinsics, while linking 64bit programs (`-march=rv64gcp
-mabi=lp64d`) works… Am I doing something wrong or is the 32bit version of the
RVP extensions currently not supported.
To link a 32bit program with P extensions, you can try this command
`-march=rv32gcp_zpn_zpsfoperand -mabi=ilp32d`.
And for this case, the compiler may only support this option at present.
> * I was also wondering why the `p` extension is not listed in the output
of `riscv64-unknown-elf-gcc -print-multi-lib`.
yes, it not be listed.
Since the file size needs to be taken into account when releasing the
package, there is no library for all instruction combinations. The latest
version of GCC source code will be opened in about two weeks, which may be
helpful to you.
