           Summary: Re-introduce support for elf32-sparc for OUTPUT_FORMAT
           Product: lld
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal

Hello!

My request is related to this review here https://reviews.llvm.org/D53495,
quote:
"Since I'm not 100% confident with BFD names you can use in the directive
for all architectures, I added only a few in this patch. We can add
other names for other archtiectures later."

I've migrated my linker to LLVM 9 and noticed that there is no support for
'elf32-sparc' as an option for the OUTPUT_FORMAT() command in the linkerscript.

This can be easily fixed in file:

https://github.com/llvm/llvm-project/blob/release/9.x/lld/ELF/ScriptParser.cpp,

by inserting:

.Case("elf32-sparc", {ELF32LEKind, EM_SPARC}) 

before the default case, at line 407.

Seems that the corresponding code is still there, so I guess it's just
inaccessible, it's not planned to be thrown out.

There is no change in the master branch, so I suppose nobody asked for
elf32-sparc support until now.

Let me know if I should add more detail.

Thanks,
Cristiana
