According to the gitattributes(5) manual, there doesn't seem to be a
git-diff driver for assembly files.

However, the default (language-independent) driver seems to handle it
reasonably well. Consider commit f4c898f2b2db
("UefiCpuPkg/CpuExceptionHandlerLib: Fix split lock", 2019-09-20).

$ git show f4c898f2b2db

this displays just the changes, with 3 lines of context, but it already
correctly displays the "HasErrorCode" label in the hunk header:

@@ -184,17 +184,19 @@ HasErrorCode:

Now, if I add "-W":

$ git show -W f4c898f2b2db

then the full text is displayed between "HasErrorCode" and "ErrorCode".

(You can see the entire file with:

$ git show f4c898f2b2db:UefiCpuPkg/Library/CpuExceptionHandlerLib/X64/ExceptionHandlerAsm.nasm

)

Thanks
