Description
Fix hipBLASLt being reported as unsupported on recent multi-arch ROCm (TheRock). Newer builds now zlib-compress the lazy Tensile library (e.g.
TensileLibrary_lazy_gfx1100.dat.zlib), which the existing check misses, soblaslt_supportedis wronglyFalse.Notes
Extends the existing check to also match the
.dat.zlibvariant in both the flat and<arch>/locations. All paths useself.name, so it stays strict per-arch and still detects the plain.dat.Environment and Testing
Windows, RDNA4, multi-arch
rocm-sdk. Confirmed hipBLASLt is now detected and runs instead of falling back to rocBLAS.
