-
-As mentioned in the PR, the fallback path when LSE is unavailable writes
-incorrect registers to the memory if the previous content compares equal
-to x0, x1 - it writes copy of x0, x1 from the start of function, but it
-should write x2, x3.

-Subject: [PATCH 1/3] aarch64: New Straight Line Speculation (SLS) mitigation
- flags
-
-Here we introduce the flags that will be used for straight line speculation.
-
-The new flag introduced is `-mharden-sls=`.
-This flag can take arguments of `none`, `all`, or a comma seperated list of one
-or more of `retbr` or `blr`.
-`none` indicates no special mitigation of the straight line speculation
-vulnerability.
-`all` requests all mitigations currently implemented.
-`retbr` requests that the RET and BR instructions have a speculation barrier
-inserted after them.
-`blr` requests that BLR instructions are replaced by a BL to a function stub
-using a BR with a speculation barrier after it.
-
-Setting this on a per-function basis using attributes or the like is not
-enabled, but may be in the future.

-Subject: [PATCH 2/3] aarch64: Introduce SLS mitigation for RET and BR
- instructions
-
-Instructions following RET or BR are not necessarily executed.  In order
-to avoid speculation past RET and BR we can simply append a speculation
-barrier.
-
-Since these speculation barriers will not be architecturally executed,
-they are not expected to add a high performance penalty.
-
-The speculation barrier is to be SB when targeting architectures which
-have this enabled, and DSB SY + ISB otherwise.
-
-We add tests for each of the cases where such an instruction was seen.
-
-This is implemented by modifying each machine description pattern that
-emits either a RET or a BR instruction.  We choose not to use something
-like `TARGET_ASM_FUNCTION_EPILOGUE` since it does not affect the
-`indirect_jump`, `jump`, `sibcall_insn` and `sibcall_value_insn`
-patterns and we find it preferable to implement the functionality in the
-same way for every pattern.
-
-There is one particular case which is slightly tricky.  The
-implementation of TARGET_ASM_TRAMPOLINE_TEMPLATE uses a BR which needs
-to be mitigated against.  The trampoline template is used *once* per
-compilation unit, and the TRAMPOLINE_SIZE is exposed to the user via the
-builtin macro __LIBGCC_TRAMPOLINE_SIZE__.
-In the future we may implement function specific attributes to turn on
-and off hardening on a per-function basis.
-The fixed nature of the trampoline described above implies it will be
-safer to ensure this speculation barrier is always used.
-
-Testing:
-  Bootstrap and regtest done on aarch64-none-linux
-  Used a temporary hack(1) to use these options on every test in the
-  testsuite and a script to check that the output never emitted an
-  unmitigated RET or BR.
-
-1) Temporary hack was a change to the testsuite to always use
-`-save-temps` and run a script on the assembly output of those
-compilations which produced one to ensure every RET or BR is immediately
-followed by a speculation barrier.
-
-gcc/ChangeLog:
-
-	* config/aarch64/aarch64-protos.h (aarch64_sls_barrier): New.
-	* config/aarch64/aarch64.c (aarch64_output_casesi): Emit
-	speculation barrier after BR instruction if needs be.
-	(aarch64_trampoline_init): Handle ptr_mode value & adjust size
-	of code copied.
-	(aarch64_sls_barrier): New.
-	(aarch64_asm_trampoline_template): Add needed barriers.
-	* config/aarch64/aarch64.h (AARCH64_ISA_SB): New.
-	(TARGET_SB): New.
-	(TRAMPOLINE_SIZE): Account for barrier.
-	* config/aarch64/aarch64.md (indirect_jump, *casesi_dispatch,
-	simple_return, *do_return, *sibcall_insn, *sibcall_value_insn):
-	Emit barrier if needs be, also account for possible barrier using
-	"sls_length" attribute.
-	(sls_length): New attribute.
-	(length): Determine default using any non-default sls_length
-	value.
-
-gcc/testsuite/ChangeLog:
-
-	* gcc.target/aarch64/sls-mitigation/sls-miti-retbr.c: New test.
-	* gcc.target/aarch64/sls-mitigation/sls-miti-retbr-pacret.c:
-	New test.
-	* gcc.target/aarch64/sls-mitigation/sls-mitigation.exp: New file.
-	* lib/target-supports.exp (check_effective_target_aarch64_asm_sb_ok):
-	New proc.

-Subject: [PATCH 3/3] aarch64: Mitigate SLS for BLR instruction
-
-This patch introduces the mitigation for Straight Line Speculation past
-the BLR instruction.
-
-This mitigation replaces BLR instructions with a BL to a stub which uses
-a BR to jump to the original value.  These function stubs are then
-appended with a speculation barrier to ensure no straight line
-speculation happens after these jumps.
-
-When optimising for speed we use a set of stubs for each function since
-this should help the branch predictor make more accurate predictions
-about where a stub should branch.
-
-When optimising for size we use one set of stubs for all functions.
-This set of stubs can have human readable names, and we are using
-`__call_indirect_x<N>` for register x<N>.
-
-When BTI branch protection is enabled the BLR instruction can jump to a
-`BTI c` instruction using any register, while the BR instruction can
-only jump to a `BTI c` instruction using the x16 or x17 registers.
-Hence, in order to ensure this transformation is safe we mov the value
-of the original register into x16 and use x16 for the BR.
-
-As an example when optimising for size:
-a
-    BLR x0
-instruction would get transformed to something like
-    BL __call_indirect_x0
-where __call_indirect_x0 labels a thunk that contains
-__call_indirect_x0:
-    MOV X16, X0
-    BR X16
-    <speculation barrier>
-
-The first version of this patch used local symbols specific to a
-compilation unit to try and avoid relocations.
-This was mistaken since functions coming from the same compilation unit
-can still be in different sections, and the assembler will insert
-relocations at jumps between sections.
-
-On any relocation the linker is permitted to emit a veneer to handle
-jumps between symbols that are very far apart.  The registers x16 and
-x17 may be clobbered by these veneers.
-Hence the function stubs cannot rely on the values of x16 and x17 being
-the same as just before the function stub is called.
-
-Similar can be said for the hot/cold partitioning of single functions,
-so function-local stubs have the same restriction.
-
-This updated version of the patch never emits function stubs for x16 and
-x17, and instead forces other registers to be used.
-
-Given the above, there is now no benefit to local symbols (since they
-are not enough to avoid dealing with linker intricacies).  This patch
-now uses global symbols with hidden visibility each stored in their own
-COMDAT section.  This means stubs can be shared between compilation
-units while still avoiding the PLT indirection.
-
-This patch also removes the `__call_indirect_x30` stub (and
-function-local equivalent) which would simply jump back to the original
-location.
-
-The function-local stubs are emitted to the assembly output file in one
-chunk, which means we need not add the speculation barrier directly
-after each one.
-This is because we know for certain that the instructions directly after
-the BR in all but the last function stub will be from another one of
-these stubs and hence will not contain a speculation gadget.
-Instead we add a speculation barrier at the end of the sequence of
-stubs.
-
-The global stubs are emitted in COMDAT/.linkonce sections by
-themselves so that the linker can remove duplicates from multiple object
-files.  This means they are not emitted in one chunk, and each one must
-include the speculation barrier.
-
-Another difference is that since the global stubs are shared across
-compilation units we do not know that all functions will be targeting an
-architecture supporting the SB instruction.
-Rather than provide multiple stubs for each architecture, we provide a
-stub that will work for all architectures -- using the DSB+ISB barrier.
-
-This mitigation does not apply for BLR instructions in the following
-places:
-- Some accesses to thread-local variables use a code sequence with a BLR
-  instruction.  This code sequence is part of the binary interface between
-  compiler and linker. If this BLR instruction needs to be mitigated, it'd
-  probably be best to do so in the linker. It seems that the code sequence
-  for thread-local variable access is unlikely to lead to a Spectre Revalation
-  Gadget.
-- PLT stubs are produced by the linker and each contain a BLR instruction.
-  It seems that at most only after the last PLT stub a Spectre Revalation
-  Gadget might appear.
-
-Testing:
-  Bootstrap and regtest on AArch64
-    (with BOOT_CFLAGS="-mharden-sls=retbr,blr")
-  Used a temporary hack(1) in gcc-dg.exp to use these options on every
-  test in the testsuite, a slight modification to emit the speculation
-  barrier after every function stub, and a script to check that the
-  output never emitted a BLR, or unmitigated BR or RET instruction.
-  Similar on an aarch64-none-elf cross-compiler.
-
-1) Temporary hack emitted a speculation barrier at the end of every stub
-function, and used a script to ensure that:
-  a) Every RET or BR is immediately followed by a speculation barrier.
-  b) No BLR instruction is emitted by compiler.
