+Subject: [PATCH] Add support for IBM Z hardware-accelerated deflate
+
+Future versions of IBM Z mainframes will provide DFLTCC instruction,
+which implements deflate algorithm in hardware with estimated
+compression and decompression performance orders of magnitude faster
+than the current zlib and ratio comparable with that of level 1.
+
+This patch adds DFLTCC support to zlib. In order to enable it, the
+following build commands should be used:
+
+ $ CFLAGS=-DDFLTCC ./configure
+ $ make OBJA=dfltcc.o PIC_OBJA=dfltcc.lo
+
+When built like this, zlib would compress in hardware on level 1, and in
+software on all other levels. Decompression will always happen in
+hardware. In order to enable DFLTCC compression for levels 1-6 (i.e. to
+make it used by default) one could either add -DDFLTCC_LEVEL_MASK=0x7e
+at compile time, or set the environment variable DFLTCC_LEVEL_MASK to
+0x7e at run time.
+
+Two DFLTCC compression calls produce the same results only when they
+both are made on machines of the same generation, and when the
+respective buffers have the same offset relative to the start of the
+page. Therefore care should be taken when using hardware compression
+when reproducible results are desired. One such use case - reproducible
+software builds - is handled explicitly: when SOURCE_DATE_EPOCH
+environment variable is set, the hardware compression is disabled.
+
+DFLTCC does not support every single zlib feature, in particular:
+
+ * inflate(Z_BLOCK) and inflate(Z_TREES)
+ * inflateMark()
+ * inflatePrime()
+ * deflateParams() after the first deflate() call
+
+When used, these functions will either switch to software, or, in case
+this is not possible, gracefully fail.
+
+This patch tries to add DFLTCC support in a least intrusive way.
+All SystemZ-specific code was placed into a separate file, but
+unfortunately there is still a noticeable amount of changes in the
+main zlib code. Below is the summary of those changes.
+
+DFLTCC takes as arguments a parameter block, an input buffer, an output
+buffer and a window. Since DFLTCC requires parameter block to be
+doubleword-aligned, and it's reasonable to allocate it alongside
+deflate and inflate states, ZALLOC_STATE, ZFREE_STATE and ZCOPY_STATE
+macros were introduced in order to encapsulate the allocation details.
+The same is true for window, for which ZALLOC_WINDOW and
+TRY_FREE_WINDOW macros were introduced.
+
+While for inflate software and hardware window formats match, this is
+not the case for deflate. Therefore, deflateSetDictionary and
+deflateGetDictionary need special handling, which is triggered using the
+new DEFLATE_SET_DICTIONARY_HOOK and DEFLATE_GET_DICTIONARY_HOOK macros.
+
+deflateResetKeep() and inflateResetKeep() now update the DFLTCC
+parameter block, which is allocated alongside zlib state, using
+the new DEFLATE_RESET_KEEP_HOOK and INFLATE_RESET_KEEP_HOOK macros.
+
+In order to make unsupported deflateParams(), inflatePrime() and
+inflateMark() calls to fail gracefully, the new DEFLATE_PARAMS_HOOK,
+INFLATE_PRIME_HOOK and INFLATE_MARK_HOOK macros were introduced.
+
+The algorithm implemented in hardware has different compression ratio
+than the one implemented in software. In order for deflateBound() to
+return the correct results for the hardware implementation, the new
+DEFLATE_BOUND_ADJUST_COMPLEN and DEFLATE_NEED_CONSERVATIVE_BOUND macros
+were introduced.
+
+Actual compression and decompression are handled by the new DEFLATE_HOOK
+and INFLATE_TYPEDO_HOOK macros. Since inflation with DFLTCC manages the
+window on its own, calling updatewindow() is suppressed using the new
+INFLATE_NEED_UPDATEWINDOW() macro.
+
+In addition to compression, DFLTCC computes CRC-32 and Adler-32
+checksums, therefore, whenever it's used, software checksumming needs to
+be suppressed using the new DEFLATE_NEED_CHECKSUM and
+INFLATE_NEED_CHECKSUM macros.
+
+DFLTCC will refuse to write an End-of-block Symbol if there is no input
+data, thus in some cases it is necessary to do this manually. In order
+to achieve this, send_bits, bi_reverse, bi_windup and flush_pending
+were promoted from local to ZLIB_INTERNAL. Furthermore, since block and
+stream termination must be handled in software as well, block_state enum
+was moved to deflate.h.
+
+Since the first call to dfltcc_inflate already needs the window, and it
+might be not allocated yet, inflate_ensure_window was factored out of
+updatewindow and made ZLIB_INTERNAL.

+
+This commit includes a CRC32 test (crc32_test). This tests are important
+since some architectures may want include CPU dependent optimizations for
+CRC32 algorithm like using vector instructions and we may want to

++ * Calculate the checksum of data that is 16 byte aligned and a multiple of
++ * 16 bytes.
++ *
++ * The first step is to reduce it to 1024 bits. We do this in 8 parallel
++ * chunks in order to mask the latency of the vpmsum instructions. If we
++ * have more than 32 kB of data to checksum we repeat this step multiple
++ * times, passing in the previous 1024 bits.
++ *
++ * The next step is to reduce the 1024 bits to 64 bits. This step adds
++ * 32 bits of 0s to the end - this matches what a CRC does. We just
++ * calculate constants that land the data in this 32 bits.
++ *
++ * We then use fixed point Barrett reduction to compute a mod n over GF(2)
++ * for n = CRC using POWER8 instructions. We use x = 32.
++ *
++ * http://en.wikipedia.org/wiki/Barrett_reduction
++ *
++ * This code uses gcc vector builtins instead using assembly directly.

+
+This change allows a parameter change even if the input data has
+not all been compressed and copied to the application output
+buffer, so long as all of the input data has been compressed to
+the internal pending output buffer. This also allows an immediate
+deflateParams change so long as there have been no deflate calls
+since initialization or reset.
