[Bug binutils/1486] New: DISASSEMBLER_NEEDS_RELOCS doesn't work correctly

[hjl at lucon dot org]

This patch

http://sourceware.org/ml/binutils/2001-01/msg00108.html

added DISASSEMBLER_NEEDS_RELOCS based in the enabled targets at configure
time. It has several problems:

1. It isn't enabled for --enable-targets=all.
2. Objdump for i386 now has 2 different assemblers, depending on if the
enabled target defines DISASSEMBLER_NEEDS_RELOCS or not.
3. The i386 assembler works incorrectly when ARM is enabled since the assembler
is different due to DISASSEMBLER_NEEDS_RELOCS.

address@hidden testsuite]$ cat y.s
 .text
glob:
 jmp ext
 jmp weak
address@hidden testsuite]$ gcc -c -m32 y.s
address@hidden testsuite]$ ../../binutils/objdump -d y.o

y.o:     file format elf32-i386

Disassembly of section .text:

00000000 <glob>:
   0:   e9 fc ff ff ff          jmp    1 <glob+0x1>
   5:   e9 fc ff ff ff          jmp    6 <weak+0x6>
                                          ^^^^ It should be "glob".

which leads to "make check" failure on Linux/x86 when 
--enable-targets=arm-linux 
is used.

I think DISASSEMBLER_NEEDS_RELOCS should be fixed and it should be enabled
at run-time depending on targets, if needed, instead of configure time.
