Struct PtxBugAnalyzer 

pub struct PtxBugAnalyzer {
    pub strict: bool,
    pub whitelist: Vec<WhitelistEntry>,
}

PTX bug hunting analyzer (inspired by probar gpu_pixels)

Fields

strict: bool

Enable strict mode (more warnings, catches PARITY-114 pattern)

whitelist: Vec<WhitelistEntry>

Whitelist for suppressing known acceptable warnings

Implementations

impl PtxBugAnalyzer

pub fn new() -> Self

Create analyzer with default (non-strict) mode

pub fn strict() -> Self

Create analyzer with strict mode enabled

pub fn with_whitelist( self, kernel_pattern: &str, bug_class: PtxBugClass, reason: &str, ) -> Self

Add a whitelist entry to suppress warnings

pub fn with_quantized_whitelist() -> Self

Create analyzer with default whitelist for quantized kernels

pub fn with_performance_whitelist() -> Self

Create analyzer with comprehensive whitelist for all high-performance kernels

This whitelist covers expected register pressure and predicate usage in:

• Tensor Core kernels (WMMA requires many registers for matrix fragments)
• Attention kernels (FlashAttention needs registers for tiling state)
• Quantized kernels (dequantization requires intermediate values)

These are documented performance tradeoffs, not bugs.

pub fn analyze(&self, ptx: &str) -> PtxBugReport

Analyze PTX for bugs

Performs copy-assignment from source.

impl Debug for PtxBugAnalyzer

fn fmt(&self, f: &mut Formatter<'_>) -> Result
