cfi: Initial support for cfi-icall in QEMU
LLVM/Clang, supports runtime checks for forward-edge Control-Flow
Integrity (CFI).
CFI on indirect function calls (cfi-icall) ensures that, in indirect
function calls, the function called is of the right signature for the
pointer type defined at compile time.
For this check to work, the code must always respect the function
signature when using function pointer, the function must be defined
at compile time, and be compiled with link-time optimization.
This rules out, for example, shared libraries that are dynamically loaded
(given that functions are not known at compile time), and code that is
dynamically generated at run-time.
This patch:
1) Introduces the CONFIG_CFI flag to support cfi in QEMU
2) Introduces a decorator to allow the definition of "sensitive"
functions, where a non-instrumented function may be called at runtime
through a pointer. The decorator will take care of disabling cfi-icall
checks on such functions, when cfi is enabled.
3) Marks functions currently in QEMU that exhibit such behavior,
in particular:
- The function in TCG that calls pre-compiled TBs
- The function in TCI that interprets instructions
- Functions in the plugin infrastructures that jump to callbacks
- Functions in util that directly call a signal handler

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.

cfi: Initial support for cfi-icall in QEMU
LLVM/Clang, supports runtime checks for forward-edge Control-Flow
Integrity (CFI).
CFI on indirect function calls (cfi-icall) ensures that, in indirect
function calls, the function called is of the right signature for the
pointer type defined at compile time.
For this check to work, the code must always respect the function
signature when using function pointer, the function must be defined
at compile time, and be compiled with link-time optimization.
This rules out, for example, shared libraries that are dynamically loaded
(given that functions are not known at compile time), and code that is
dynamically generated at run-time.
This patch:
1) Introduces the CONFIG_CFI flag to support cfi in QEMU
2) Introduces a decorator to allow the definition of "sensitive"
functions, where a non-instrumented function may be called at runtime
through a pointer. The decorator will take care of disabling cfi-icall
checks on such functions, when cfi is enabled.
3) Marks functions currently in QEMU that exhibit such behavior,
in particular:
- The function in TCG that calls pre-compiled TBs
- The function in TCI that interprets instructions
- Functions in the plugin infrastructures that jump to callbacks
- Functions in util that directly call a signal handler

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.

tcg/tci: Change encoding to uint32_t units
This removes all of the problems with unaligned accesses
to the bytecode stream.
With an 8-bit opcode at the bottom, we have 24 bits remaining,
which are generally split into 6 4-bit slots. This fits well
with the maximum length opcodes, e.g. INDEX_op_add2_i32, which
have 6 register operands.
We have, in previous patches, rearranged things such that there
are no operations with a label which have more than one other
operand. Which leaves us with a 20-bit field in which to encode
a label, giving us a maximum TB size of 512k -- easily large.
Change the INDEX_op_tci_movi_{i32,i64} opcodes to tci_mov[il].
The former puts the immediate in the upper 20 bits of the insn,
like we do for the label displacement. The later uses a label
to reference an entry in the constant pool. Thus, in the worst
case we still have a single memory reference for any constant,
but now the constants are out-of-line of the bytecode and can
be shared between different moves saving space.
Change INDEX_op_call to use a label to reference a pair of
pointers in the constant pool. This removes the only slightly
dodgy link with the layout of struct TCGHelperInfo.
The re-encode cannot be done in pieces.
