[PATCH v2 0/4] OvmfPkg/RiscVVirt: Add CLANGDWARF toolchain support

[Sunil V L]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4478

This series adds support for building RiscVVirtQemu EDK2 using
CLANGDWARF toolchain. Adding this support helps people to use
the same toolchain to build EDK2 for different architectures.

[PATCH v2 1/4] OvmfPkg/RiscVVirt: use 'auto' alignment and FIXED for XIP modules

[Sunil V L]

Use auto alignment and FIXED FFS attribute for XIP modules similar
to [1]. Without this change, the CLANGDWARF toolchain will fail to
build with below error.

GenFfs: ERROR 1000: Unknown option
  SectionAlign option must be specified with section file.

[PATCH v2 2/4] OvmfPkg/RiscVVirt: SecEntry: Remove unnecessary assembly directives

[Sunil V L]

llvm fails to resolve _ModuleEntry when these extra directives are
present. ASM_FUNC already takes care what is required.

[PATCH v2 3/4] BaseTools/tools_def: Add CLANGDWARF support for RISC-V

[Sunil V L]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4478

Add tools_def definitions to support CLANGDWARF toolchain
for RISC-V. This uses clang and the llvm LLD linker. This
helps people by not requiring to install multiple
cross compilers for different architectures.

Hi Liming,

I tested with toolchain 13, 14, 15, 16 and latest 17. (Like clang-13,
lld-13, llvm-*-13, ...). I didn't test prior to v13 considering the
churn happening for RISC-V. Do you recommend any particular version I
should test / support?

Thanks,
Sunil

Hi Liming,

Could you please provide RB/ACK tag so that Ard can merge this? We would
like to get this support added for upcoming stable release.

Thanks!
Sunil

If nobody objects, I will merge this tomorrow with or without an ack
from the BaseTools maintainers.
