LLVM LLD linker doesn't support common-page-size option. So, max-page-size
is used. To not impact GCC tool chain, new ClangBase.lds is added.

CLANG8ELF tool chain generated ELF image with the different attributes
in section. Update GenFw to handle them.
1. .text section with writable attribute (support)
2. .reloc section has the symbol for *ABS* (skip)

This commit breaks many of the ARM platforms.
I end up seeing
GenFw: Elf64Convert.c:719: ScanSections64: Assertion `FALSE' failed.
when generating certain ACPI tables.
Note: this applies to both GCC5 and CLANG38 - it is not isolated to
CLANG8ELF.
Reverting to commit c1aa3bab1259 makes these builds work again.

Leif,
Sorry to hear that. It seems a CI gap that doesn't capture such errors.
It looks like the logic update to detect .text section doesn't work in your case.
I am trying to build the OVMF Bhyve because I saw it contains an AcpiTables module that has .aslc file.
Thanks,
Ray

Leif,
OVMF Bhyve GCC build succeeds without GenFW assertion issue.
I dumped the ELF image generated for OvmfPkg/Bhyve/AcpiTables/AcpiTables.
Below output shows that .text does have "AX" set:
---
$ readelf -S Hpet.dll
...
[ 1] .text PROGBITS 0000000000000000 00000140
000000000000000c 0000000000000000 AX 0 0 64
---
It matches IsTextShdr() logic:
return (BOOLEAN) ((Shdr->sh_flags & (SHF_EXECINSTR | SHF_ALLOC)) == (SHF_EXECINSTR | SHF_ALLOC));
Can you please check the .text attributes in your ARM build?
(
I did try to build an ARM platform but failed with following errors:
gcc: error: unrecognized command line option '-mcmodel=small'
I downloaded "arm-none-eabi-gcc" in Ubuntu:
lrwxrwxrwx 1 root root 25 Jun 5 09:18 /usr/bin/gcc -> /usr/bin/arm-non-eabi-gcc

Ray:
When convert the image to ACPI data, only data section is required. So, we
can update GenFw tool not do this check when convert ACPI data.
I just send the patch to update GenFw tool.
This issue happens on GCC49 tool chain. So, it is not detected in open CI
with GCC5 tool chain.
Below is the attributes for the generated aslc elf image with GCC49. Its .
text section has no CODE attribute.
Sections:
Idx Name Size VMA LMA File off
Algn
0 .text 00000008 0000000000000000 0000000000000000 00010000

BZ:https://bugzilla.tianocore.org/show_bug.cgi?id=1603
LLVM/CLANG8 formal release http://releases.llvm.org/download.html#8.0.0
It can be downloaded and installed in Windows/Linux/Mac OS.
CLANG8ELF tool chain is added to generate ELF image, and convert to PE/COFF.
On Windows OS, set CLANG_HOST_BIN=n, set CLANG8_BIN=LLVM installed directory
For example:
set CLANG_HOST_BIN=n # use windows nmake
set CLANG8_BIN=C:\Program Files\LLVM\bin\
On Linux/Mac, set CLANG8_BIN=LLVM installed directory
This tool chain can be used to compile the firmware code. On windows OS,
Visual Studio is still required to compile BaseTools C tools and nmake.exe.
On Linux/Mac OS, gcc is used to compile BaseTools C tools. make is used
for makefile.
This tool chain is verified on OVMF Ia32, X64 and Ia32X64 to boot Shell.
This tool chain is verified in Windows/Linux and Mac OS.

CLANGDWARF is more proper because it's similar to CLANGPDB that generates

This toolchain is needed for creating ELF format universal payload that
follows https://universalpayload.github.io/documentation/.
