Remove the stubbed implementation of FCSM_TR (Forward Condition Set Mode -
Thread Reduction) flow test and replace it with an initial implementation
using SFlag and ZFlag conditions. This provides basic functionality while
allowing for future refinement based on specific shader architecture
requirements.
- In commit b3facaa6bb, the copyright header was
updated to include "Citron Homebrew Project" across multiple files, regardless
of whether any contributions were made.
- This commit removes the incorrect attribution and reverts the copyright header
to its previous state.
- Copyright attribution should only be added when meaningful contributions have
been made to the file.
- This commit ensures proper compliance with copyright standards and maintains
correct attribution to the respective contributors.
- Special thanks to Tachi for pointing out the need for these corrections and
ensuring that proper attribution practices are followed.
Simplifies the negative reciprocal calculation in FSWZADD by using the
dedicated FPRecip operation instead of manually constructing a division.
This change:
- Replaces FPDiv(Imm32(f32(1.0f)), src_b) with FPRecip(src_b)
- Results in more efficient code for calculating 1.0/x
- Fixes build errors from undefined IR emitter methods
Fixes incorrect method names in the floating point swizzled add implementation:
- FNeg -> FPNeg
- FDiv -> FPDiv
- FImm32(1.0f) -> Imm32(ir.f32(1.0f))
These changes align with the correct IR emitter interface naming conventions,
where floating-point operations use the 'FP' prefix and immediate values are
properly constructed using f32().
Implements the Internal Stage Buffer Entry Read (ISBERD) instruction in the
Maxwell shader recompiler. This replaces the previous stubbed implementation
with actual buffer reading functionality.
The implementation:
- Validates unsupported features (skew, o, mode, shift)
- Performs buffer read using IR::InternalStageBufferRead
- Stores the read value to the destination register
This removes the "(STUBBED) called" warning messages that were previously
being logged during shader compilation.
Implements the ISBERD (Internal Stage Buffer Entry Read) instruction's
mode and shift options that were previously throwing NotImplemented
exceptions. This includes:
- Patch mode for reading patch data
- Prim mode for reading primitive data
- Attr mode for reading attribute data
- U16 shift for 16-bit unsigned values
- B32 shift for 32-bit values
The implementation follows Maxwell's ISA specification for handling
different buffer read modes and data shifts.
