* Create `il_fp_ops.inc`, for floating-point instructions' IL ops
* Add IL implementation for `FABS`
* Also add `x86_il_{get,set}_st_reg` helper functions
* Add IL implementation for `FNINIT` and `FLDCW`
* Add IL implementations for `FNSTCW` and `FNSTSW`
* Add IL implementation for `FNCLEX`
* Add ST push and pop functions
* Fix clang formatting
* Add fucntions for updating FPSW TOP pointer
* Add `FLD` instruction lifitng, FPSW flag support, FP operand support
* Remove `x86_bool_to_bv` and use the standard `BOOL_TO_BV`
* Add implementation for `FST{P}`, and rounding mode support
* Add `FLD` variants for constants
* Fix formatting and build
* Add IL lifting for `FXCH`
* Add width checks to avoid redundant rounding
* Implement IL lifting for `FILD`, `FIST{P}`
* Add helper functions to inter-convert floating point values and
integers using the rounding mode in the control word
* FPU stack regs are 80-bit, not 64-bit
* Add RzIL lifting for `FBLD`
* Add RzIL implementation for `FBSTP`
* An invalid-arithmetic-operand (#IA) exception may occurr if the
value being converted to the BCD integer cannot fit in an 18-bit
BCD integer. For the IL's purpose, we just jump to the "int" label
(stands for interrupt) using `GOTO`.
* Remove all the `EMPTY()` ops after `GOTO()` ops
* On second thought, using `EMPTY()` ops after `GOTO()` ops is not
the best idea to indicate end of analysis. Maybe the hooks can
signal that analysis needs to be restarted.
* Also, clean up the comments of a bunch of unimplemented ops
* Moved some code around
* Rename "rmode" local variable to "_rmode"
* Add some TODOs for deffered work
* Fix failing asm tests
* Caused due to the removal of the [empty] opcode
* Implement IL lifting for `FADD` (and some other minor refactoring)
* Implement the IL lifting for `FADD`: This is not entirely correct
as of now, because we don't handle setting C1 based on rounding
up/down, but I think it should be fine for now. Need to tackle
setting the control word bits later
* Start using `RzFloatFormat` to describe the float's width instead
of using an unsigned integer. Provide and expose conversion
functions between the two
* Use a global to denote when RMode needs to be init, implement FIADD
* Other minor refactor which fixes the CI (hopefully)
* Implement `FMUL` and `FIMUL`
* Extract the common code into a C macro
* Implement RzIL for `FSUB` and `FISUB`
* Also add `x86_il_fsub_with_rmode` helper
* Implement RzIL for `FSUBR` and `FISUBR`
* Reuse the implementation of `x86_il_fsub_with_rmode` and just pass
the arguments in the opposite order
* Add RzIL implementation for `FDIV`, `FIDIV`, `FDIVR`, `FIDIVR`
* Add pop versions of floating point arithmetic instuctions
* Add a new macro `X86_ARITHMETIC_POP_IL` macro for the same
* Fix a typo
* Add a note for using `X86_INS_PFADD` for FADDP instruction on
Capstone version newer than 4
* Add RzIL implementations for `FCOM`, `FCOMP` and `FCOMPP`
* Add RzIL lifting for `FUCOM` and `FCOMI` families of instructions
* Implement RzIL lifting for `FCHS` and `FTST`
* Add RzIL implementation for `FRNDINT` and `FSQRT`
* Add RzIL implementation for `FNOP` and `FISTTP`
* Remove global variable `use_rmode` and use pass around a context instead
* Define a new `X86ILContext` struct to pass around information
whether we need to intitialize the rouding mode or not
* Remove the global variable which was previously responsible for
doing so
* Add RzIL for `FICOM` and `FICOMP`, add register bindings and fix bugs
* Make `rz-test` more robust against IL outputs with newlines in them
* Add RzIL tests in db/asm for x86 FPU instructions
* Fix the bug when using `FADDP` with Capstone version > 4
* Fix remaining db tests
* Remove tests for `FSTSW` or `FSTCW` instructions
* We already test `WAIT` (in `db/asm/x86_32`) and `FSTSW` (or
`FSTCW`) (in `db/asm/x86_64`)
* Remove the newline replacement code in `rz-test` as well, since we
wouldn't need that functionality anymore
* Add asm tests for math constant push instructions
* Add `RZ_IPI` annotation for all the functions exposed through the header
* Add `RZ_OWN`, `RZ_BORROW` and `RZ_NONNULL` annotations
* Add Doxygen doc for `ctx` argument
* Add description for the `EXEC_WITH_RMODE` macro
* Move the non-null check for `ctx` inside the valid branch
* When we pop the FPU stack we pass in a `NULL` context since no
resizing would be needed, which causes a failure if the non-null
check for the `ctx` is outside the branch
* Fixes failing tests in `db/asm`
* Minor bug fixes + make the annotations less strict than they need to be
* Minor bug fixes
* Incorrect implementation for `RET` and `CALL`
* Swapped arguments for shift right
* Fix asm tests for `JMP` and `RET` instructions
* Fix indexing error for `FXCH`
* Review changes
* Move all unimplemented instructions to the end
* Remove support for Capstone version less than 4
