Nick Clifton 3ce3a066e1 This fixes the processing of BFD_RELOC_RL78_DIFF fixups when the size is less
than 4.  This affects DWARF debug info generation in particular.

	* config/tc-rl78.c (md_apply_fix): Correct handling of small sized
	RELOC_RL78_DIFF fixups.

Alan Modra e57e6ddc2e Prepare gas for 64-bit obstacks
Use size_t in a few places involved with obstacks, and don't include
obstack.h in files that don't use obstacks.

Kaushik Phata 856ea05ccf This adds support for marking RL78 binaries as either supporting 32-bit
or 64-bit doubles.  It also makes the linker complain if the user attempts
to link together binaries with different sized doubles.

	64-bit doubles objects mix with 32-bit doubles objects.

	and OPTION_64BIT_DOUBLES.

DJ Delorie 0a899fd5ac Add checks for overfar branches
Check 8 and 16 bit PCREL fixes for overflow, since we bypass the
later overflow checks in write.c.  Direct relocs are left alone,
as gcc has been known to take advantage of the silent overflows
when comparing addresses to constant ranges.

	relocation is used on an 8-bit operand or vice versa.

DJ Delorie 0c315784bf Add opcode relaxation for rl78-elf
This patch adds initial in-gas opcode relaxation for the rl78
backend.  Specifically, it checks for conditional branches that
are too far and replaces them with inverted branches around longer
fixed branches.

DJ Delorie c9d665580e Ensure that %func() expressions are outermost terms
This is to avoid expressions like:  %hi(foo) + 1, which will
not do what you expect.  The complex relocations can handle it,
but the internal fixups can't.
