This patch adds the new instruction and relocation as per proposal:
https://openrisc.io/proposals/ladrp
This is to be added to the spec in an upcoming revision. The new instruction
l.adrp loads the page offset of the current instruction offset by
a 21-bit immediate shifted left 13-bits. This is meant to be used with
a 13-bit lower bit page offset. This allows us to free up the got
register r16.
l.adrp r3, foo
l.ori r4, r3, po(foo)
l.lbz r5, po(foo)(r3)
l.sb po(foo)(r3), r6
The relocations we add are:
- BFD_RELOC_OR1K_PLTA26 For PLT jump relocation with PLT entry
asm: plta() implemented using l.ardp, meaning
no need for r16 (the GOT reg)
- BFD_RELOC_OR1K_GOT_PG21 Upper 21-bit Page offset got address
asm: got()
- BFD_RELOC_OR1K_TLS_GD_PG21 Upper 21-bit Page offset with TLS General
asm: tlsgd() Dynamic calculation
- BFD_RELOC_OR1K_TLS_LDM_PG21 Upper 21-bit Page offset with TLS local
asm: tlsldm() dynamic calculation
- BFD_RELOC_OR1K_TLS_IE_PG21 Upper 21-bit Page offset with TLS Initial
asm: gottp() Executable calculation
- BFD_RELOC_OR1K_PCREL_PG21 Default relocation for disp21 (l.adrp
instructions)
- BFD_RELOC_OR1K_LO13 low 13-bit page offset relocation
asm: po() i.e. mem loads, addi etc
- BFD_RELOC_OR1K_SLO13 low 13-bit page offset relocation
asm: po() i.e. mem stores, with split immediate
- BFD_RELOC_OR1K_GOT_LO13, low 13-bit page offset with GOT calcs
asm: gotpo()
- BFD_RELOC_OR1K_TLS_GD_LO13 Lower 13-bit offset with TLS GD calcs
asm: tlsgdpo()
- BFD_RELOC_OR1K_TLS_LDM_LO13 Lower 13-bit offset with TLS LD calcs
asm: tlsldmpo()
- BFD_RELOC_OR1K_TLS_IE_LO13 Lower 13-bit offset with TLS IE calcs
asm: gottppo()

The calculation of the shift amount, used to insert fields into the
instruction buffer, is not correct when the following conditions are all
true:
- CGEN_INT_INSN_P is defined, and true.
- CGEN_INSN_LSB0_P is true
- Total instruction length is greater than the length of a single
instruction word (the instruction is made of multiple words)
- The word offset is non-zero (the field is outside the first word)
When the above conditions are all true, the calculated shift fails to
take account of the total instruction length.
After this commit the calculation of the shift amount is split into two
parts, first we calculate the shift required to get to BIT0 of the word
in which the field lives, then we calculate the shift required to place
the field within the instruction word.
The change in this commit only effects the CGEN_INT_INSN_P defined true
case, but changes the code for both CGEN_INSN_LSB0_P true, and false.
In the case of CGEN_INSN_LSB0_P being false, the code used to say:
shift = total_length - (word_offset + start + length);
Now it says:
shift_to_word = total_length - (word_offset + word_length);
shift_within_word = word_length - start - length;
shift = shift_to_word + shift_within_word;
From which we can see that in all cases the computed shift value should
be unchanged.
In the case of CGEN_INSN_LSB0_P being true, the code used to say:
shift = (word_offset + start + 1) - length;
Now it says:
shift_to_word = total_length - (word_offset + word_length);
shift_within_word = start + 1 - length;
shift = shift_to_word + shift_within_word;
In the case where 'total_length == word_length' AND 'word_offset ==
0' (which indicates an instruction of a single word), we see that the
computed shift value will be unchanged. However, when the total_length
and word_length are different, and the word_offset is non-zero then the
computed shift value will be different (and correct).
