- Unicode 13 beta data as of 2019-nov-21
- uprops.icu format version 7.7 with more bits for Script/Script_Extensions
- more bits in spoof checker ScriptSet
- root line break rules adjusted for UAX 14 changes, from Andy
- line break tailorings not yet in sync with root
The purpose of the FIELD_NAME_STR() macro is to create a string literal
by using the # preprocessing operator and then skip the first 5 chars of
this string by using the +5 pointer arithmetic. This is all intentional,
but if the parentheses are misplaced the compiler might think that this
is a mistake, a failed string concatenation (-Wstring-plus-int).
The test fails for "America/Argentina/ComodRivadavia", which has length
of 32, the same as the buffer. The results in the string being not
terminated with a NUL.
This increases the buffer size used by the test, and also checks for the
string not terminated warning.
This enables "classic" desktop builds of ICU4C for both ARM (32-bit)
and ARM64 (64-bit) on Windows.
All but the two samples "cal" and "date" in the "allinone" project now
have ARM and ARM64 project configurations, and build for Windows Desktop
ARM/ARM64.
Note: In order to build the ARM/ARM64 data DLL, you need to first build
x64/Release, as the ARM/ARM build uses the x64 bits in order to be able
to cross-compile for ARM/ARM64. This allows for completely building
ARM/ARM64 binaries using only x64 hardware.
The ARM/ARM64 builds require using a newer version of the Windows SDK
than 8.1, so they have a separate WindowsTargetPlatformVersion which
uses Windows 10 SDK version 10.0.16299.0 (aka RS3), which is the first
version of the Windows SDK to support building ARM64 desktop applications.
In addition this also greatly cleans-up the ICU4C ".vcxproj" files, in
order to remove redundant parts, fix inconsistencies, and make them more
readable. This introduces two new variables in the shared `*.props`
files: `IcuBinOutputDir` and `IcuLibOutputDir` in order to further
reduce the amount of duplicated lines in the individual ".vcxproj"
files themselves.
Using the C++ SFINAE (substitution failure is not an error) technique,
it's possible to provide an icu::StringPiece constructor that accepts
any string view type that might be available in the current compilation
unit, without adding any additional dependencies or configuration flags
to ICU.
The way these macros currently are defined, the code compiles also
without the final semicolons. But for consistency and in order to allow
the macro definitions to be updated also these macro invocations should
have final semicolons just like in the rest of this code base.
