Subject: [PATCH] RISC-V: Adjust -march flags for binutils 2.38
|
|
|
|
As of version 2.38 binutils defaults to ISA specification version
|
|
2019-12-13. This version of the specification has has separated the
|
|
the csr read/write (csrr*/csrw*) instructions and the fence.i from
|
|
the I extension and put them into separate Zicsr and Zifencei
|
|
extensions.
|
|
|
|
This implies that we have to adjust the -march flag passed to the
|
|
compiler accordingly.
