[Bug gas/873] New: Incorrect generation of relocs for .byte , .2byte and .3byte directives.

[ramana dot radhakrishnan at codito dot com]

A .byte expression should generate an R_ARC_8 and not an R_ARC_32 as is 
generated
currently.Similary .2byte and .3byte directives should generate R_ARC_16 and
R_ARC_24 directives and not R_ARC_32 as is generated currently. The .byte ,
.2byte and .3byte directives work in spaces less than 4 bytes so generating a
R_ARC_32 is incorrect in such a case. 


.section .data
. = 0x10
 .byte .L1
        ;; .2byte .L2
.3byte .L3
.L1:
        .4byte 0
.L2:
        .4byte 1
.L3:
        .4byte 2

.section .text
start :
        mov r0,0

generates a reloc of the following format. 

RELOCATION RECORDS FOR [.data]:
OFFSET   TYPE              VALUE
00000010 R_ARC_32          .data
00000011 R_ARC_32          .data



With the .2byte directive the assembler gives an internal error.

/home/ramana/tmp/try.s:4: Error: internal error: can't export reloc type 5
(`BFD_RELOC_16')
