Implement the ECOFF `.aent' pseudo-op for ECOFF-style `.mdebug' section
support with ELF objects and, for consistency, also with ECOFF objects.
This is so that the same MIPS source can be assembled without and with
`.mdebug' section generation enabled.
Taking the `gas/testsuite/gas/mips/aent.s' test case source as an
example and the `mips-linux' target we have:
$ as -o aent.o aent.s
$ as -mdebug -o aent.o aent.s
aent.s: Assembler messages:
aent.s:10: Error: unknown pseudo-op: `.aent'
$
because for the !ECOFF_DEBUGGING case (which is the default) the
pseudo-op is already handled by the MIPS backend with `s_mips_ent',
however no handler is present for the opposite case.
For the MIPS target this is a functional regression introduced with
commit ecb4347ade ("Last take: approval for MIPS_STABS_ELF killing"),
<https://sourceware.org/ml/binutils/2002-06/msg00443.html>, where
support for the `.mdebug' section was added along with its associated
`-mdebug'/`-no-mdebug' command-line options, bringing an inconsistency
between the assembly syntax supported for each of these options as far
as the `.aent' pseudo-op is concerned.
Assembly language documentation available describes the pseudo-op
respectively as follows[1]:
"
.aent name, symno Sets an alternate entry point for the current
procedure. Use this information when you want
to generate information for the debugger. It must
appear inside an .ent/.end pair."
and[2]:
"
.aent name [,symno]
Sets an alternate entry point for the current procedure. Use this
information when you want to generate information for the debugger.
This directive must appear between a pair of .ent and .end directives.
(The optional symno is for compiler use only. It refers to a dense
number in a .T file (symbol table).)"
Copy the approach from `s_mips_ent' then and add `.aent' support to the
`.ent' pseudo-op handler shared between the ELF and ECOFF object file
format backends, by setting BSF_FUNCTION for the symbol requested.
