Is this a bug?

[Stephen Thomas]

Hi,

I have just hit a problem with SH5 binutils (V2.12.1), which I can best
illustrate with the following bit of assembler (this situation can never
arise from pure C):

        .section        .text..SHmedia32,"ax"
        .align 5
        .type   hhh,@function
hhh:
        .align 5
        .global ggg
        .type   ggg,@function
ggg:
        movi    (((address@hidden) >> 16) & 65535), r1
        shori   ((address@hidden) & 65535), r1

Note that hhh is not marked as global. The above assembles OK, & an
'objdump -r' of the resulting object shows relocations for hhh. But when the
object file is linked, the linker gives the following errors (& aborts the
link):

z.o: In function `ggg':
z.o(.text..SHmedia32+0x0):dangerous relocation: Unexpected STO_SH5_ISA32 on
local symbol is not handled
z.o(.text..SHmedia32+0x4):dangerous relocation: Unexpected STO_SH5_ISA32 on
local symbol is not handled

It looks like the linker thinks that because hhh is non-global, it doesn't
have a GOT entry for it. The equivalent code works fine on x86 binutils (or
at least, it does on V2.11.90.8). But there is an entry in bfd/ChangeLog on
2002-02-28 which implies this is deliberate behaviour on SH5.

Could you please clarify whether this is a bug or not?
