Make build failure on NetBSD/i386 1.2

Make build failure on NetBSD/i386 1.2

[Andreas Gustafsson]

I just tried building egcs-1.0 on NetBSD/i386 1.2
(i386-unknown-netbsd-1.2) using the system's stock cc, which is
actually gcc 2.7.2.  "make build" failed at the following point (long
line broken for the benefit of limited mail software):

   $ /x/egcs-1.0/configure --enable-shared
   Created "Makefile" in /x/egcs-obj using "/x/egcs-1.0/config/mh-x86pic" and "/x/egcs-1.0/config/mt-x86pic"
   Links are now set up to build a native compiler for i386-unknown-netbsd1.2

Your help is appreciated.

Hmmm, your assembler might need to be updated.  That's the only thing that comes
immediately to mind.

Hmm, updated to what?  The NetBSD-1.3_ALPHA assembler turned out to have
the same problem as the 1.2 one (both are based on gas-1.92.3).

I tried installing gas from binutils-2.8.1, but that didn't work
either because it does not recognize the "-k" option which egcs passes
to the assembler when building shared libraries with -fpic on NetBSD
systems.

In case it helps, here's the egcs-generated assembler code that
triggers the problem.  Apparently the assembler is confused by the
".align 2" directive occurring between two labels whose difference is
computed (the error disappears if you remove the ".align 2").

___FRAME_BEGIN__:
        .long LLCIE1

LSCIE1:
        .long 0

                .byte   0x1
                .byte   0x0
                .byte   0x1
                .byte   0x7c
                .byte   0x8
                .byte   0xc
                .byte   0x5
                .byte   0x4
                .byte   0x88
                .byte   0x1
        .align 2
LECIE1:
        .set    LLCIE1,LECIE1-LSCIE1

I would guess a 2.8.1 vintage, but not being a netbsd/alpha person I really
don't know.

gas-1.92.3 is horribly old, no wonder it doesn't work.
