FT32B is a new FT32 family member. It has a code
compression scheme, which requires the use of linker
relaxations. The change is quite large, so submission
is in several parts.
Part 1 adds a 15-bit instruction field, and CPU-specific functions for
the code compression that are used in binutils and GDB.

Add support for the Imagination interAptiv MR2 MIPS32r3 processor with
the MIPS16e2 ASE as per documentation, including in particular:
1. Support for implementation-specific interAptiv MR2 COPYW and UCOPYW
MIPS16e2 instructions[1], for assembly and disassembly,
2. Support for implementation-specific interAptiv MR2 SAVE and RESTORE
regular MIPS instructions[2], for assembly and disassembly,
3. ELF binary file annotation for the interAptiv MR2 MIPS architecture
extension.
4. Support for interAptiv MR2 architecture selection for assembly, in
the form of the `-march=interaptiv-mr2' command-line option and its
corresponding `arch=interaptiv-mr2' setting for the `.set' and
`.module' pseudo-ops.
5. Support for interAptiv MR2 architecture selection for disassembly,
in the form of the `mips:interaptiv-mr2' target architecture, for
use e.g. with the `-m' command-line option for `objdump'.

This came up because I was looking at ld/tmpdir/addpcis.o and noticed
the odd addends on REL16DX_HA. They ought to both be -4. The error
crept in due REL16DX_HA howto being pc-relative (as indeed it should
be), and code at gas/write.c:1001 after this comment
/* Make it pc-relative. If the back-end code has not
selected a pc-relative reloc, cancel the adjustment
we do later on all pc-relative relocs. */
*not* cancelling the pc-relative adjustment. So I've made a dummy
non-relative split reloc so that the generic code handles this, rather
than attempting to add hacks later in md_apply_fix which would not be
very robust. Having the new internal reloc also makes it easy to
support
addpcis rx,sym@ha
as an equivalent to
addpcis rx,(sym-0f)@ha
0:
The patch also fixes overflow checking, which must test whether the
addi will overflow too since @l relocs don't have any overflow check.
Lastly, since I was poking at md_apply_fix, I arranged to have the
generic gas/write.c code emit errors for subtraction expressions where
we lack reloc support.

Before this commit we didn't cleanly support CFI directives because the
internal offsets used to get relaxed which broke them. This patch
significantly reworks how we handle linker relaxations:
* DWARF is now properly supported
* There is a ".option norelax" to disable relaxations, for when users
write assembly that can't be relaxed (if it's to be later patched up,
for example).
* There is an additional _RELAX relocation that specifies when previous
relocations can be relaxed.
We're in the process of documenting the RISC-V ELF ABI, which will
include documentation of our relocations
https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md
but we expect that this relocation set will remain ABI compatible in the
future (ie, it's safe to release).
Thanks to Kuan-Lin Chen for figuring out how to correctly relax the
debug info!

ld/
* emultempl/armelf.em (params): New static variable.
(thumb_entry_symbol, byteswap_code, target1_is_rel, target2_type,
fix_v4bx, use_blx, vfp11_denorm_fix, stm32l4xx_fix, fix_cortex_a8,

Added support for ARC_SDA_12 reloc.
Fixed ARC_N32_ME.
Added ME (middle-endian) to ARC_SDA_12 reloc.
bfd/ChangeLog:
Cupertino Miranda <cmiranda@synopsys.com>
* reloc.c: Fixed type in ARC_SECTOFF relocations. Added ARC_SDA_12
relocation.
* bfd-in2.h: Regenerated from the previous changes.
* libbfd.h: Regenerated from the previous changes.
include/ChangeLog:
Cupertino Miranda <cmiranda@synopsys.com>

bfd/
* bfd-in.h (bfd_elf32_arm_set_target_relocs): Add a new parameter for
the input import library bfd.
* bfd-in2.h: Regenerate.
* elf32-arm.c (struct elf32_arm_link_hash_table): New in_implib_bfd
and new_cmse_stub_offset fields.
(stub_hash_newfunc): Initialize stub_offset and stub_template_size to
-1.
(elf32_arm_add_stub): Likewise for stub_offset.
(arm_new_stubs_start_offset_ptr): New function.
(arm_build_one_stub): Only allocate a stub_offset if it is -1. Allow
empty SG veneers to have zero relocations.
(arm_size_one_stub): Only initialize stub size and template
information for non empty veneers. Do not update veneer section size
if veneer already has an offset.
(elf32_arm_create_stub): Return the stub entry pointer or NULL instead
of a boolean indicating success or failure.
(cmse_scan): Change stub_changed parameter into an integer pointer
parameter cmse_stub_created to count the number of stub created and
adapt to change of return value in elf32_arm_create_stub.
(cmse_entry_fct_p): New function.
(arm_list_new_cmse_stub): Likewise.
(set_cmse_veneer_addr_from_implib): Likewise.
(elf32_arm_size_stubs): Define cmse_stub_created, pass its address to
cmse_scan instead of that of cmse_stub_changed to compute the number
of stub created and use it to initialize stub_changed. Call
set_cmse_veneer_addr_from_implib after all cmse_scan. Adapt to change
of return value in elf32_arm_create_stub. Use
arm_stub_section_start_offset () if not NULL to initialize size of
secure gateway veneers section. Initialize stub_offset of Cortex-A8
erratum fix to -1. Use ret to hold return value.
(elf32_arm_build_stubs): Use arm_stub_section_start_offset () if not
NULL to initialize size of secure gateway veneers section. Adapt
comment to stress the importance of zeroing veneer section content.
(bfd_elf32_arm_set_target_relocs): Add new in_implib_bfd parameter to
initialize eponymous field in struct elf32_arm_link_hash_table.
