+Decompressor. Algorithm Ported from OPSD code (Decomp.asm)
+for Efi and Tiano compress algorithm.
-Module Name:
+Based on the upstream EDK2 implementation (BaseTools/Source/C/Common/Decompress.c)

-Abstract:
-
- Decompressor. Algorithm Ported from OPSD code (Decomp.asm)
- for Efi and Tiano compress algorithm.
+Public API adapted to use size_t parameters to match this project's Decompress.h.
+Internal state uses UINT32 throughout (matching upstream) since all bit-buffer
+arithmetic assumes 32-bit width (BITBUFSIZ = 32).
