passing any value to that parameter which has the same size as the
parameter (it basically acts as if there is an explicit type conversion
to the parameter type around the value at the caller side). If a procvar
has an univ parameter, all procvars whose corresponding parameter
has the same size as that univ parameter are similarly compatible.
This transparent compatibility can however cause crashes in case of
of the procvars when one of the types is passed on the stack and the
other isn't (because then the called routine will a) load the parameter
from a wrong location and b) pop the wrong amount off of the stack at
then end). Therefore FPC will warn in most cases where this can happen.

because the associated simplifications can turn invalid statements
into valid statements (based on patch by Aleksa Todorovic, mantis
#15594)
git-svn-id: trunk@14998 -
- pass address to SafeCallException method(rtl needed a modification)
- improve code generation for regular safecall routines (not methods)
- improve test - check that passed exception and address are valid

properties/behaviour of the equivalent of Extended in C (i.e., to
"long double" on i386 and x86_64 platforms that support a 10 byte
long double, and to "double" elsewhere)

compares by avoiding unnecessary sign extensions (fixes bug reported in
http://lists.freepascal.org/lists/fpc-pascal/2010-January/023907.html )
* never throw away int2int type conversions on bitpacked loads, because
in these cases the proper bits still need to be selected

a) is also set to true for packages (when packages will beimplemented)
b) exists for each package/library/application separately, instead of
being stored in the package containing the system unit (when packages
will be implemented)

Objective-C methods or which are fields of Objective-C classes (since they
are basically opaque to the Objective-C runtime) + fixed tobjc11 so it
expects classes to be encoded as opaque types
* give a proper error message when using illegal field/parameter types in
Objective-C classes/methods instead of an internal error (only checked
during rtti generation rather than during parsing, because during parsing
some types may still be forwarddefs)
* split objcutil in objcdef and objcutil, with objcdef depending only on
the symtable so it can be used in symdef

so the TMultiReadExclusiveWriteSynchronizer routines can be safely
executed even with the default thread manager -> removed ismultithread
checks, so that it keeps working even if ismultithread is set to true
between acquiring and freeing a lock (mantis #15619)
git-svn-id: trunk@14830 -
- fix arguments description if the first argument is empty
- fix restype field value (describes result value type in variant types)
