             Bug #: 14814
           Summary: problem in linking files which contain some farcall
                    instructions with -r
           Product: binutils
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


These are three test cases that triggers the bug
The back end of the GCC compiler is arm
=========================
a.s
 .global _start
 .text
_start:
 bl bar_b
 bl bar_c   
=========================
b.s 
.global bar_b
bar_b:
  bx lr
=========================
c.s
 .global bar_c
 .space 0x02000008
bar_c:
  bx lr
Instruction BL bar_c in a.s is a farcall instruction
First use assemble them individually,then we got a.o,b.o,c.o
Then link a.o c.o with -r,and got ac.o
But when link ac.o with b.o,the linker emits these
 ac.o: In function `_start':
  c.c:(.text+0x0): relocation truncated to fit: R_ARM_CALL against symbol     
`bar_b' defined in .text section in b.o
  c.c:(.text+0x4): relocation truncated to fit: R_ARM_CALL against symbol
`bar_c' defined in .text section in ac.o

When I change the link order like this 
ld a.o b.o -o ab.o
ld ab.o c.o -o abc.out
The linker works.
