Currently, it's not possible to manually set some of the v850 archs in
gdb:
(gdb) set architecture v850<TAB>
v850 (using old gcc ABI)
v850-rh850
v850e
v850e (using old gcc ABI)
v850e1
[...]
(gdb) set architecture v850 (using old gcc ABI)
Ambiguous item "v850 (using old gcc ABI)".
The problem is that "set architecture" is a GDB "enum command", and
GDB only considers an enum value to be the string up until the first
space. So writing "v850 (using old gcc ABI)" is the same as writing
"v850", and then that's not an unambiguous arch printable name prefix.
v850 is actually the only arch that has spaces in its printable name.
One can conveniently see that with e.g.:
(gdb) set max-completions unlimited
(gdb) complete set architecture
...
Rather than hack GDB into accepting this somehow, make v850 arch
printable names more like the printable names of the other archs, and
put the abi variant in the "machine" part, after a ':'.
We now get:
(gdb) set architecture v850<TAB>
v850:old-gcc-abi
v850:rh850
v850e
v850e1
v850e1:old-gcc-abi
v850e2
v850e2:old-gcc-abi
[...]
And now "set architecture v850:old-gcc-abi" works as expected.
I ran the binutils/gas/ld testsuites, and found no regressions. I
don't have a cross compiler handy, but I ran the gdb tests anyway,
which covers at least some snoke testing.
I think that the OUTPUT_ARCH in ld/scripttempl/v850.sc may have got
broken with the previous 2012 change, since I hacked v850_rh850.sc to
output "v850" and ld failed to grok it. I think it only works if the
old GCC ABI is the configured v850 default ABI. That's now fixed by
changing to use explicit v850:old-gcc-abi.
Also, this actually "fixes" an existing GDB test, which isn't likewise
expecting spaces in arch names, when GDB is configured for
--target=v850:
(gdb) FAIL: gdb.xml/tdesc-arch.exp: read valid architectures

When .data and .bss sections are empty .noinit section is placed at data
region's start. This will be incorrect for devices that has different
data start address than data region start in linker script.

section will be placed at .data section address (-Tdata=<address>) when .data
and .bss sections are empty.

Adjusting the start of the relro segment in order to make it end
exactly on a page boundary runs into difficulties when sections in the
relro segment are aligned; Adjusting the start by (next_page - end)
sometimes results in more than that adjustment occurring at the end,
overrunning the page boundary. So when that occurs we try a new lower
start position by masking the adjusted start with the maximum section
alignment. However, we didn't consider that this masked start address
may in fact be before the initial relro base, which is silly since
that can only increase padding at the relro end.
I've also moved some calculations closer to where they are used, and
comments closer to the relevant statements.
