Compiled regular expression patterns make use of several shared common
UnicodeSets. This change simplifies the creation and use of these
static UnicodeSets.
- Pointer fields to the static sets are removed from the compiled patterns,
and the static variables are accessed directly. The deleted pointers
were a hold-over from earlier code that did not use shared statics.
- The UnicodeSet pattern literals are changed from hex constants to
u"string literals".
- The size of fRuleSets (from regexst.h) is changed from a hard-coded 10
to the number of UnicodeSets actually required. Doing this required
a change to regexcst.pl to export the required size. Changing and
rerunning this perl code resulted in massive but benign changes to
the generated file regexcst.h, the result of perl having changed its
order of enumeration of hashes since the file was last regenerated.
- UnicodeSets are frozen when possible. Should result in faster matching.
The definition of max_align_t is not guaranteed to be available unless
the appropriate header is included. Since use of <stddef.h> from C++ is
deprecated, that's <cstddef>, and max_align_t is thus defined under the
std namespace rather than in the global namespace.
DateTimePatternGenerator needs to consider the hour-cycle preferred by
Locale. This means that we need to to override the hour-cycle when a
locale contains "hc" keyword. This patch is adding such functionality.
In addition, "DateTimePatternGenerator::adjustFieldTypes" should adjust
hour field to properly follow tr35
spec(https://www.unicode.org/reports/tr35/tr35-dates.html#dfst-hour).
This would cause failures during cross compilation cases such as:
make[6]: Leaving directory '/spksrc/spk/bazarr/work-qoriq-6.1/icu/source/data'
make[5]: *** No rule to make target 'out', needed by 'out/icudt64b.dat'. Stop.
- equivalent but originally unequal
- locale distance shifted left for additional fraction bits with micro distance
- Java more verbose matcher debug output

- Merge the look-ahead results slots used when multiple rules share a common accepting state.
- Sequentially number the look-ahead result slot. Will eventually allow replacing the runtime map with an array.
- Inhibit chaining out of look-ahead rules. This could never actually happen; when a hard break
rule matches, the engine is stopped immediately, but the state table was being constructed
as if it could happen. Reduces table size for line break rules.
- Remove incorrect handling of fAccepting and fLookAhead fields of a state table row
when removing duplicate states. Look-ahead slot number was being mis-interpreted as a state number.
It's not available with some libc implementations. Specifically,
BIONIC and uClibc-ng. uprv_ variants are available.

When C code includes the ICU headers, the UChar type is defined to be
uint16_t. But when C++ code includes the headers, UChar is char16_t
even when U_SHOW_CPLUSPLUS_API has been set to 0. Apart from arguably
being an inconsistency in the API, this means that C++98 or C++03 code
can't use the C API even though C99 code can.
So, change unicode/umachine.h to check not just whether __cplusplus is
defined but the value of U_CPLUSPLUS_VERSION when deciding how to
typedef UChar.
