Current if we need to access a GOT entry, we use the
got_base + offset. Thus we have GOT and XGOT.
From MIPSr6, we have PCREL instructions like ALUIPC,
so we have no need to use got_base now.
For pre-R6, we can use BAL to get the the value of PC.

In this patch, we add 8 new relocs:
	R_MIPS_GOTPC_HI16, R_MIPS_GOTPC_LO16,
	R_MIPS_GOTPC_CALL_HI16, R_MIPS_GOTPC_CALL_LO16,
	R_MIPS_GOTPC_AHI16, R_MIPS_GOTPC_ALO16,
	R_MIPS_GOTPC_CALL_AHI16, R_MIPS_GOTPC_CALL_ALO16.
These asm notes can be used for them:
	%gotpc_hi(sym), %gotpc_lo(sym),
	%gotpc_call_hi(sym), %gotpc_call_lo(sym),
	%gotpc_ahi(sym), %gotpc_alo(sym),
	%gotpc_call_ahi(sym), %gotpc_call_alo(sym).

3 new BFD_RELOCS are added for ALUIPC style relocs:
	BFD_RELOC_MIPS_ALO16_GOTOFF,
	BFD_RELOC_MIPS_AHI16_GOTOFF,
	BFD_RELOC_MIPS_AHI16_S_GOTOFF.

6 new BFD_RELOCS are added for function calling:
	BFD_RELOC_MIPS_LO16_GOTOFF_CALL,
	BFD_RELOC_MIPS_HI16_GOTOFF_CALL,
	BFD_RELOC_MIPS_HI16_S_GOTOFF_CALL,
	BFD_RELOC_MIPS_ALO16_GOTOFF_CALL,
	BFD_RELOC_MIPS_AHI16_GOTOFF_CALL,
	BFD_RELOC_MIPS_AHI16_S_GOTOFF_CALL,

The mapping between BFD_RELOC_ and R_MIPS_GOTPC are:
	BFD_RELOC_HI16_S_GOTOFF -> R_MIPS_GOTPC_HI16
	BFD_RELOC_LO16_GOTOFF -> R_MIPS_GOTPC_LO16
	BFD_RELOC_MIPS_HI16_S_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_HI16
	BFD_RELOC_MIPS_LO16_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_LO16.
	BFD_RELOC_MIPS_AHI16_S_GOTOFF -> R_MIPS_GOTPC_AHI16
	BFD_RELOC_MIPS_ALO16_GOTOFF -> R_MIPS_GOTPC_ALO16
	BFD_RELOC_MIPS_MIPS_AHI16_S_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_AHI16
	BFD_RELOC_MIPS_MIPS_ALO16_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_ALO16.

The difference of BAL and ALUIPC is that ALUIPC will unset the lower 16
bits of result.

For r6, both styles are supported, and of course ALUIPC style is
recommended. For pre-R6, only BAL style is supported.

Here are the ASM examples:
ALUIPC:
	aluipc	$2,%gotpc_ahi(sym)
	lw	$2,%gotpc_alo(sym)($2)

BAL:
	bal	. + 8 # Note: $31 is clobbered here.
	lui	$2,%gotpc_hi(sym)
	addiu	$2,$2,$31
	lw	$2,%gotpc_lo(sym)($2)

 I'm assuming ">" above is a typo; overall the change description may need 
a little bit polishing, but let's leave it until all the issues with code 
itself have been sorted.

 I've skimmed over your change and spotted a couple of issues right away, 
as noted below.  I'll go through your change more thoroughly again.

 Have the new relocations been formally documented anywhere?

 For RELA relocations you need to set `partial_inplace' to `false' and 
`src_mask' to 0, because they do not store the addend in the field 
relocated.  Likewise throughout and with n32.

 Please follow the GNU coding style, i.e.:

  return (r_type == R_MIPS_GOT_LO16
	  || r_type == R_MIPS_GOTPC_LO16
	  || r_type == R_MIPS_GOTPC_ALO16
	  || r_type == R_MICROMIPS_GOT_LO16);

Likewise throughout.

Not yet. I wanted to put the documents in some subdirectory of binutils or gcc,
while it seems that these doc directories were used to hold the documents of
these projects only.

Is it a good idea to host the new document on Github or somewhere else?

For contents, I think that we should have a document for all GNU extensions.
Let's use the new relocs as the starting point.

Thanks.

Currently loading a GOT entry requires loading the GOT base address
first, then adding an offset. Therefore, (elaborate the reason)
we need both GOT and XGOT. MIPSr6 introduced PC-relative instructions
like ALUIPC/AUIPC, which allow us to use a pair of GOTPC_HI and
GOTPC_LO to materialize the GOT entry address.

GCC's mips port names assembler relocation operators
(gas/config/tc-mips.c names them `mips_percent_op`).
Other ports seem to prefer "modifiers" (assembler modifiers,
expression modifiers).

* [PATCH v4] MIPS: Support PCREL GOT access

Current if we need to access a GOT entry, we use the
got_base + offset. Thus we have GOT and XGOT.
From MIPSr6, we have PCREL instructions like ALUIPC,
so we have no need to use got_base now.
For pre-R6, we can use BAL to get the the value of PC.

In this patch, we add 8 new relocs:
	R_MIPS_GOTPC_HI16, R_MIPS_GOTPC_LO16,
	R_MIPS_GOTPC_CALL_HI16, R_MIPS_GOTPC_CALL_LO16,
	R_MIPS_GOTPC_AHI16, R_MIPS_GOTPC_ALO16,
	R_MIPS_GOTPC_CALL_AHI16, R_MIPS_GOTPC_CALL_ALO16.
These asm notes can be used for them:
	%gotpc_hi(sym), %gotpc_lo(sym),
	%gotpc_call_hi(sym), %gotpc_call_lo(sym),
	%gotpc_ahi(sym), %gotpc_alo(sym),
	%gotpc_call_ahi(sym), %gotpc_call_alo(sym).

3 new BFD_RELOCS are added for ALUIPC style relocs:
	BFD_RELOC_MIPS_ALO16_GOTOFF,
	BFD_RELOC_MIPS_AHI16_GOTOFF,
	BFD_RELOC_MIPS_AHI16_S_GOTOFF.

6 new BFD_RELOCS are added for function calling:
	BFD_RELOC_MIPS_LO16_GOTOFF_CALL,
	BFD_RELOC_MIPS_HI16_GOTOFF_CALL,
	BFD_RELOC_MIPS_HI16_S_GOTOFF_CALL,
	BFD_RELOC_MIPS_ALO16_GOTOFF_CALL,
	BFD_RELOC_MIPS_AHI16_GOTOFF_CALL,
	BFD_RELOC_MIPS_AHI16_S_GOTOFF_CALL,

The mapping between BFD_RELOC_ and R_MIPS_GOTPC are:
	BFD_RELOC_HI16_S_GOTOFF -> R_MIPS_GOTPC_HI16
	BFD_RELOC_LO16_GOTOFF -> R_MIPS_GOTPC_LO16
	BFD_RELOC_MIPS_HI16_S_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_HI16
	BFD_RELOC_MIPS_LO16_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_LO16.
	BFD_RELOC_MIPS_AHI16_S_GOTOFF -> R_MIPS_GOTPC_AHI16
	BFD_RELOC_MIPS_ALO16_GOTOFF -> R_MIPS_GOTPC_ALO16
	BFD_RELOC_MIPS_MIPS_AHI16_S_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_AHI16
	BFD_RELOC_MIPS_MIPS_ALO16_GOTOFF_CALL -> R_MIPS_GOTPC_CALL_ALO16.

The difference of BAL and ALUIPC is that ALUIPC will unset the lower 16
bits of result.

For r6, both styles are supported, and of course ALUIPC style is
recommended. For pre-R6, only BAL style is supported.

Here are the ASM examples:
ALUIPC:
	aluipc	$2,%gotpc_ahi(sym)
	lw	$2,%gotpc_alo(sym)($2)

BAL:
	bal	. + 8 # Note: $31 is clobbered here.
	lui	$2,%gotpc_hi(sym)
	addiu	$2,$2,$31
	lw	$2,%gotpc_lo(sym)($2)
