Subject: Makefile: fix build with binutils 2.38
|
|
|
|
Git-commit: 5d53b55aa77ffeefd4012445dfa6ad3535e1ff2c
|
|
|
|
From version 2.38, binutils default to ISA spec version 20191213. This
|
|
means that the csr read/write (csrr*/csrw*) instructions and fence.i
|
|
instruction has separated from the `I` extension, become two standalone
|
|
extensions: Zicsr and Zifencei. As the kernel uses those instruction,
|
|
this causes the following build failure:
|
|
|
|
CC lib/sbi/sbi_tlb.o
|
|
<<BUILDDIR>>/lib/sbi/sbi_tlb.c: Assembler messages:
|
|
<<BUILDDIR>>/lib/sbi/sbi_tlb.c:190: Error: unrecognized opcode `fence.i'
|
|
make: *** [Makefile:431: <<BUILDDIR>>/build/lib/sbi/sbi_tlb.o] Error 1
|
|
|
|
The fix is to specify those extensions explicitly in -march. However as
|
|
older binutils version do not support this, we first need to detect
|
|
that.
