Since commit ee68d3eb8c (jsoncpp: Add script to update from upstream,
2017-08-28, v3.10.0-rc1~199^2~8) we use a script to maintain the jsoncpp
vendor branch. Drop our readme that documented the old approach.
Divert LCC compiler as a new one, instead of treating it as GNU.
Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been
passing checks for GNU compilers, so it has been identified as GNU.
Now, with intent of seriously upstreaming its support, it has been
added as a separate LCC compiler, and its version displays not a
supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead
of GNU 7.3.0).
This commit adds its support for detection, and also converts basically
every check like 'is this compiler GNU?' to 'is this compiler GNU or
LCC?'. The only places where this check is untouched, is where it
regards other platforms where LCC is unavailable (primarily non-Linux),
and where it REALLY differs from GNU compiler.
Note: this transition may break software that are already ported to
Elbrus, but hardly relies that LCC will be detected as GNU; still such
software is not known.
* Deprecation removals previously specific to MSVC/Intel now also used
by clang
* String literals were assigned to non const pointers. These are stored
in mutable arrays now
* An implicit function pointer to pointer conversion is a Microsoft
extension warning is suppressed by an explicit reinterpret_cast
* The MSVC specific deprecation macro for jsoncpp was moved after the
clang macro to avoid redefinition warnings. This is consistent with
how jsoncpp fixed the issue in 36d8cfd7
In commit beb991110d (Remove now-unused code once used on IRIX,
2019-01-11, v3.14.0-rc1~167^2) we removed remnants of IRIX support.
Also remove remnants of MIPSpro compiler support.
Clang's ubsan (-fsanitize=undefined) reports:
runtime error: negation of -9223372036854775808 cannot be represented in
type 'Json::Value::LargestInt' (aka 'long'); cast to an unsigned type to
negate this value to itself
Follow its advice and update the code to remove the explicit negation.
The scanbuild analysis cannot see that decodeUnicodeEscapeSequence
either initializes the `unicode` argument or returns `false` such
that the code following it runs only if `unicode` is initialized.
Add an explicit initialization to pacify it.
Even though we disable warnings when building jsoncpp itself, including
its headers from other CMake sources may still cause warnings.
Additional work will be needed to port CMake to newer jsoncpp interfaces
while still supporting jsoncpp 1.0.0. For now, just suppress the
markup.
When parsing digits we know our `c - '0'` expression results in a
non-negative value due to preceding conditions. Simply cast the result
to UInt. This fixes compilation on SolarisStudio 12.4.
Some versions of HP-UX do not define 'isfinite' or 'finite' in math.h
for Itanium when preprocessing with C++, so we have to add the
definition ourselves instead to map to the internal version.
Even though we disable warnings when building jsoncpp itself, including
its headers from other CMake sources may still cause warnings. Update
the code to remove these -Wdocumentation warnings.
Update json/json.h to account for our lack of autolink.h. Update
json/config.h to include KWSys Large File Support configuration so that
consistent stream libraries are used (on AIX with XL).
Add a cm_jsoncpp_reader.h header to include the CMake-provided copy of
the json/reader.h header from CMake sources.
