Some suggestions:
1. There are many blanks appending the line "+ "$(DLINK)" -o ${dst} $(DLINK_FLAGS) @$(STATIC_LIBRARY_FILES_LIST) "
[cid:image001.png@01D75263.998291F0]
1. We need a toolchain dependency descirption in the BaseTools\Conf\tools_def.template. Below is the example for CLANGPDB. Please add one for the CLANGDWARF.
# CLANGPDB -Linux, Windows, Mac- Requires:
# Clang 9 or above from http://releases.llvm.org/
# Optional:
# Required to compile nasm source:
# nasm compiler from
# NASM -- http://www.nasm.us/
# Required to build platforms or ACPI tables:
# Intel(r) ACPI Compiler from
# https://acpica.org/downloads
1. We could merge the CLANG38 and the CLANGDWARF toolchains together in the future.
Thanks

Ray:
I would like to suggest CLANGDWARF also generate EFI image. If so, the
people can use this tool chain for EFI development with DWARF format debug
symbol.
In dll generation phase, CLANGDWARF still generates dll image, then copy
dll image to elf image. In EFI generation phase, dll image will be converted
to EFI image.
Thanks

主题: Re: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Some suggestions:
1. There are many blanks appending the line “+ "$(DLINK)" -o
${dst} $(DLINK_FLAGS) @$(STATIC_LIBRARY_FILES_LIST) “
2. We need a toolchain dependency descirption in the
BaseTools\Conf\tools_def.template. Below is the example for CLANGPDB. Please
add one for the CLANGDWARF.
# CLANGPDB -Linux, Windows, Mac- Requires:
# Clang 9 or above from
http://releases.llvm.org/
# Optional:
# Required to compile nasm source:
# nasm compiler from
# NASM -- http://www.nasm.us/
# Required to build platforms or ACPI tables:
# Intel(r) ACPI Compiler from
# https://acpica.org/downloads
3. We could merge the CLANG38 and the CLANGDWARF toolchains together in
the future.
Thanks

Liming,
that is not the intention of this new toolchain.
we want to have a toolchain that can generate elf. or can you suggest a new name for this toolchain?
thanks,
ray

Ray:
If the tool chain generates ELF image, its ELF image can be converted to
EFI image by Edk2 GenFw tool. Then, this tool chain can be used for EFI
development.
So, I propose to make CLANGDWARF tool chain generate ELF image and EFI
image both. It can support the usage of ELF image generation.
Thanks

主题: Re: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Liming,
that is not the intention of this new toolchain.
we want to have a toolchain that can generate elf. or can you suggest a new
name for this toolchain?
thanks,
ray

Subject: 回复: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF
toolchain
Ray:
I would like to suggest CLANGDWARF also generate EFI image. If so, the
people can use this tool chain for EFI development with DWARF format debug
symbol.
In dll generation phase, CLANGDWARF still generates dll image, then copy
dll image to elf image. In EFI generation phase, dll image will be converted
to EFI image.
Thanks

主题: Re: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Some suggestions:
1. There are many blanks appending the line “+ "$(DLINK)" -o
${dst} $(DLINK_FLAGS) @$(STATIC_LIBRARY_FILES_LIST) “
2. We need a toolchain dependency descirption in the
BaseTools\Conf\tools_def.template. Below is the example for CLANGPDB. Please
add one for the CLANGDWARF.
# CLANGPDB -Linux, Windows, Mac- Requires:
# Clang 9 or above from
http://releases.llvm.org/
# Optional:
# Required to compile nasm source:
# nasm compiler from
# NASM -- http://www.nasm.us/
# Required to build platforms or ACPI tables:
# Intel(r) ACPI Compiler from
# https://acpica.org/downloads
3. We could merge the CLANG38 and the CLANGDWARF toolchains together in
the future.
Thanks
Steven Shi

Liming,
I happen to notice the below patches which you sent out two years ago:
https://edk2.groups.io/g/devel/topic/31354044#41053
It seems to me that I can drop my CLANGDWARF change completely and use your patches.
Correct?
Thanks,
Ray

Subject: 回复: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Ray:
If the tool chain generates ELF image, its ELF image can be converted to EFI image by Edk2 GenFw tool. Then, this tool chain can be used for EFI development.
So, I propose to make CLANGDWARF tool chain generate ELF image and EFI image both. It can support the usage of ELF image generation.
Thanks

主题: Re: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Liming,
that is not the intention of this new toolchain.
we want to have a toolchain that can generate elf. or can you suggest a new name for this toolchain?
thanks,
ray

Subject: 回复: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Ray:
I would like to suggest CLANGDWARF also generate EFI image. If so, the people can use this tool chain for EFI development with DWARF format debug symbol.
In dll generation phase, CLANGDWARF still generates dll image, then copy dll image to elf image. In EFI generation phase, dll image will be converted to EFI image.
Thanks

主题: Re: [edk2-devel] [PATCH 1/4] BaseTools: Create CLANGDWARF toolchain
Some suggestions:
1. There are many blanks appending the line “+ "$(DLINK)" -o ${dst} $(DLINK_FLAGS) @$(STATIC_LIBRARY_FILES_LIST) “
2. We need a toolchain dependency descirption in the BaseTools\Conf\tools_def.template. Below is the example for CLANGPDB. Please add one for the CLANGDWARF.
# CLANGPDB -Linux, Windows, Mac- Requires:
# Clang 9 or above from http://releases.llvm.org/
# Optional:
# Required to compile nasm source:
# nasm compiler from
# NASM -- http://www.nasm.us/
# Required to build platforms or ACPI tables:
# Intel(r) ACPI Compiler from
# https://acpica.org/downloads
3. We could merge the CLANG38 and the CLANGDWARF toolchains together in the future.
Thanks
Steven Shi

Original CLANGELF tool chain is verified on CLANG8. Can you verify it to see whether it meet with your requirement?
If yes, this tool chain can be renamed to CLANGDWARF to match current CLANGPDB tool chain.
