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. +--- + Makefile.in | 8 + + configure | 13 + + contrib/README.contrib | 4 + + contrib/s390/dfltcc.c | 901 ++++++++++++++++++++++++++++++++++ + contrib/s390/dfltcc.h | 55 +++ + contrib/s390/dfltcc_deflate.h | 50 ++ + deflate.c | 60 ++- + deflate.h | 12 + + gzguts.h | 4 + + inflate.c | 84 +++- + inflate.h | 2 + + test/infcover.c | 2 +- + test/minigzip.c | 4 + + trees.c | 13 +- + 14 files changed, 1161 insertions(+), 51 deletions(-) + create mode 100644 contrib/s390/dfltcc.c + create mode 100644 contrib/s390/dfltcc.h + create mode 100644 contrib/s390/dfltcc_deflate.h + +diff --git a/Makefile.in b/Makefile.in +index 5a77949..e756e2f 100644 +--- a/Makefile.in ++++ b/Makefile.in +@@ -143,6 +143,14 @@ match.lo: match.S + mv _match.o match.lo + rm -f _match.s + ++dfltcc.o: $(SRCDIR)contrib/s390/dfltcc.c $(SRCDIR)zlib.h zconf.h ++ $(CC) $(CFLAGS) $(ZINC) -c -o $@ $(SRCDIR)contrib/s390/dfltcc.c ++ ++dfltcc.lo: $(SRCDIR)contrib/s390/dfltcc.c $(SRCDIR)zlib.h zconf.h ++ -@mkdir objs 2>/dev/null || test -d objs ++ $(CC) $(SFLAGS) $(ZINC) -DPIC -c -o objs/dfltcc.o $(SRCDIR)contrib/s390/dfltcc.c ++ -@mv objs/dfltcc.o $@ ++ + example.o: $(SRCDIR)test/example.c $(SRCDIR)zlib.h zconf.h + $(CC) $(CFLAGS) $(ZINCOUT) -c -o $@ $(SRCDIR)test/example.c + +diff --git a/configure b/configure +index e974d1f..8fab355 100755 +--- a/configure ++++ b/configure +@@ -826,6 +826,19 @@ EOF + fi + fi + ++# Check whether sys/sdt.h is available ++cat > $test.c << EOF ++#include ++int main() { return 0; } ++EOF ++if try ${CC} ${CFLAGS} $test.c; then ++ echo "Checking for sys/sdt.h ...
