MerryMage 9c4f234417 fuzz_with_unicorn: Avoid self-modifying code 
* Don't immediately terminate when unicorn raises an interrupt
* Detect self-modifying code
 2020-04-22 20:46:19 +01:00
MerryMage 9f8c6f60f5 fuzz_with_unicorn: Configure as per qemu max configuration 2020-04-22 20:46:19 +01:00
Lioncash 64d4e40081 tests/A32/testenv: Add type aliases for register arrays 
Allows avoiding duplicating std::array instance sizes and types.
 2020-04-22 20:46:19 +01:00
Lioncash a25bacc436 tests/unicorn: Add type aliases to the Unicorn class 
Centralizes all register and vector array definitions to a single set of
aliases, so if these are ever changed, then the rest of the testing code
will follow suit without the need to manually change them.

MerryMage 8c65d58cb8 tests/A64: Randomize FPCR.RMode for single random instruction 2020-04-22 20:46:18 +01:00
Lioncash 7d52d7bef8 inst_gen: Compress loop into std::any_of in IsInvalidInstruction() 
Same behavior, but using a more self-documenting function.
 2020-04-22 20:46:18 +01:00
Lioncash d909b0919e fuzz_with_unicorn: Move std::vector outside loop in small random block test case 
Avoids constructing and destructing the vector repeatedly, we can just
alter the contents of the vector on each iteration instead. Also move
out the std::array instances as well, like with the floating-point test
case and the single random instruction test case.

We can also use the regular form of std::generate and avoid hardcoding
size values twice.

MerryMage 330e6111fa fuzz_with_unicorn: Randomize FPCR.RMode 2020-04-22 20:46:18 +01:00
MerryMage eb3ca7f65b tests: Add print_info program 
Eases debugging by printing out dynarmic IR for a given A64 instruction, along with
information about what instruction dynarmic thinks it is.

Also prints an LLVM disassembly of the instruction.

MerryMage 8c90fcf58e IR: Implement FPMulAdd 2020-04-22 20:46:18 +01:00
Lioncash e64978ed89 fuzz_with_unicorn: Make float_numbers in floating-point tests constexpr 
Given this is just a lookup table, this can be made immutable.
 2020-04-22 20:46:18 +01:00
Lioncash 329137a277 fuzz_with_unicorn: Remove exclusion of FMOV (imm) for FP-16 floats 
Qemu, or rather, Unicorn now supports FP-16, since I backported support
for the recent changes to mainline Qemu relating to FP-16 support.
 2020-04-22 20:46:18 +01:00
Lioncash 0c63e8f396 fuzz_with_unicorn: Silence unused variable warning 
Currently, structured bindings don't provide a way to ignore unused variables.
 2020-04-22 20:46:17 +01:00
Lioncash cd0b71159a CMake: Make FindUnicorn introduce a unicorn target 
Makes the find module do all the work of properly setting up the target instead of needing to do it in the main CMakeLists file.
 2020-04-22 20:46:16 +01:00
Lioncash ab58bbddc8 unicorn: Be explicit about casting away const to const-incorrect APIs 
Uses C++ casts which silence relevant warnings in Xcode 9.3

Also migrates relevant Read function equivalents over for consistency.

Lioncash 71422c2b48 fuzz_with_unicorn: Move data outside loop 
Given we know we're only ever going to use one instruction, we can just presize the vector and reassign to it
instead of potentially reallocating the same memory 100000 times

- Add missing include
- Fix a potential compilation issue where the constructor wouldn't be able to execute, as it would be private.
