* externals: Add oaksim submodule Used for emitting ARM64 assembly * common: Implement aarch64 ABI Utilize oaknut to implement a stack frame. * tests: Allow shader-jit tests for x64 and a64 Run the shader-jit tests for both x86_64 and arm64 targets * video_core: Initialize arm64 shader-jit backend Passes all current unit tests! * shader_jit_a64: protect/unprotect memory when jit-ing Required on MacOS. Memory needs to be fully unprotected and then re-protected when writing or there will be memory access errors on MacOS. * shader_jit_a64: Fix ARM64-Imm overflow These conditionals were throwing exceptions since the immediate values were overflowing the available space in the `EOR` instructions. Instead they are generated from `MOV` and then `EOR`-ed after. * shader_jit_a64: Fix Geometry shader conditional * shader_jit_a64: Replace `ADRL` with `MOVP2R` Fixes some immediate-generation exceptions. * common/aarch64: Fix CallFarFunction * shader_jit_a64: Optimize `SantitizedMul` Co-authored-by: merryhime <merryhime@users.noreply.github.com> * shader_jit_a64: Fix address register offset behavior Based on https://github.com/citra-emu/citra/pull/6942 Passes unit tests. * shader_jit_a64: Fix `RET` address offset A64 stack is 16-byte aligned rather than 8. So a direct port of the x64 code won't work. Fixes weird branches into invalid memory for any shaders with subroutines. * shader_jit_a64: Increase max program size Tuned for A64 program size. * shader_jit_a64: Use `UBFX` for extracting loop-state Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit_a64: Optimize `SUB+CMP` to `SUBS` Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit_a64: Optimize `CMP+B` to `CBNZ` Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit_a64: Use `FMOV` for `ONE` vector Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit_a64: Remove x86-specific documentation * shader_jit_a64: Use `UBFX` to extract exponent Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit_a64: Remove redundant MIN/MAX `SRC2`-NaN check Special handling only needs to check SRC1 for NaN, not SRC2. It would work as follows in the four possible cases: No NaN: No special handling needed. Only SRC1 is NaN: The special handling is triggered because SRC1 is NaN, and SRC2 is picked. Only SRC2 is NaN: FMAX automatically picks SRC2 because it always picks the NaN if there is one. Both SRC1 and SRC2 are NaN: The special handling is triggered because SRC1 is NaN, and SRC2 is picked. Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit/tests:: Add catch-stringifier for vec2f/vec3f * shader_jit/tests: Add Dest Mask unit test * shader_jit_a64: Fix Dest-Mask `BSL` operand order Passes the dest-mask unit tests now. * shader_jit_a64: Use `MOVI` for DestEnable mask Accelerate certain cases of masking with MOVI as well Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> * shader_jit/tests: Add source-swizzle unit test This is not expansive. Generating all `4^4` cases seems to make Catch2 crash. So I've added some component-masking(non-reordering) tests based on the Dest-Mask unit-test and some additional ones to test broadcasts/splats and component re-ordering. * shader_jit_a64: Fix swizzle index generation This was still generating `SHUFPS` indices and not the ones that we wanted for the `TBL` instruction. Passes all unit tests now. * shader_jit/tests: Add `ShaderSetup` constructor to `ShaderTest` Rather than using the direct output of `CompileShaderSetup` allow a `ShaderSetup` object to be passed in directly. This enabled the ability emit assembly that is not directly supported by nihstro. * shader_jit/tests: Add `CALL` unit-test Tests nested `CALL` instructions to eventually reach an `EX2` instruction. EX2 is picked in particular since it is implemented as an even deeper dispatch and ensures subroutines are properly implemented between `CALL` instructions and implementation-calls. * shader_jit_a64: Fix nested `BL` subroutines `lr` was getting writen over by nested calls to `BL`, causing undefined behavior with mixtures of `CALL`, `EX2`, and `LG2` instructions. Each usage of `BL` is now protected with a stach push/pop to preserve and restore teh `lr` register to allow nested subroutines to work properly. * shader_jit/tests: Allocate generated tests on heap Each of these generated shader-test objects were causing the stack to overflow. Allocate each of the generated tests on the heap and use unique_ptr so they only exist within the life-time of the `REQUIRE` statement. * shader_jit_a64: Preserve `lr` register from external function calls `EMIT` makes an external function call, and should be preserving `lr` * shader_jit/tests: Add `MAD` unit-test The Inline Asm version requires an upstream fix: https://github.com/neobrain/nihstro/issues/68 Instead, the program code is manually configured and added. * shader_jit/tests: Fix uninitialized instructions These `union`-type instruction-types were uninitialized, causing tests to indeterminantly fail at times. * shader_jit_a64: Remove unneeded `MOV` Residue from the direct-port of x64 code. * shader_jit_a64: Use `std::array` for `instr_table` Add some type-safety and const-correctness around this type as well. * shader_jit_a64: Avoid c-style offset casting Add some more const-correctness to this function as well. * video_core: Add arch preprocessor comments * common/aarch64: Use X16 as the veneer register https://developer.arm.com/documentation/102374/0101/Procedure-Call-Standard * shader_jit/tests: Add uniform reading unit-test Particularly to ensure that addresses are being properly truncated * common/aarch64: Use `X0` as `ABI_RETURN` `X8` is used as the indirect return result value in the case that the result is bigger than 128-bits. Principally `X0` is the general-case return register though. * common/aarch64: Add veneer register note `LR` is generally overwritten by `BLR` anyways, and would also be a safe veneer to utilize for far-calls. * shader_jit_a64: Remove unneeded scratch register from `SanitizedMul` * shader_jit_a64: Fix CALLU condition Should be `EQ` not `NE`. Fixes the regression on Kid Icarus. No known regressions anymore! --------- Co-authored-by: merryhime <merryhime@users.noreply.github.com> Co-authored-by: JosJuice <JosJuice@users.noreply.github.com> |
