o made all (non-abstract) tdef and tsym constructors virtual
o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
class
o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
class from the base classes, and initialises the c*def/c*sym classes with
them. This is done so that the llvm target will be able to derive from
the tcpu*def/sym classes without umpteen ifdefs, and it also means that
the WPO can devirtualise everything because the c* variables are only
initialised with one class type
o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
calls

since it performs exactly the same thing as the generic signed 32-bit handling
in the else clause (regardless of whether cpuneedsmulhelper is defined or not)

defcmp.pas:
+ add new function "def_is_related" which combines the "is_related" overloads of "tobjectdef", "trecorddef" and "tstringdef" (it returns "false" for other def types which is what "tdef.is_related" did)
* compare_defs_ext & compatible_childmethod_resultdef: change call from "x.is_related" to "def_is_related(x,...)"
symtype.pas, tdef:
- remove "is_related" method
symdef.pas:
- remove "is_related" in "tobjectdef", "trecorddef" and "tstringdef"
* tobjectdef.needs_inittable: for checking whether a Corba interface somehow inherits from a IInterface don't use "is_related" anymore (we want to avoid the dependency after all), but mimic the necessary functionality of "def_is_related"
htypechk.pas, nadd.pas, ncal.pas, ncnv.pas, ngtcon.pas, nld.pas, optvirt.pas, pdecobj.pas, pdecvar.pas, pexpr.pas, pgenutil.pas:

type with a non-default code page
TODO: ensure that string constants typecasted to ansistring become
ansistrings rather than typeless string constants
git-svn-id: trunk@25207 -
CP_ACP (defaultsystemcodepage), because if all input strings have the
same code page then the result should also have that code page if it's
assigned to a rawbytestring rather than getting defaultsystemcodepage
* do not consider empty strings to determine the code page of the result
in fpc_AnsiStr_Concat_multi(), because that will cause a different
result than when using a sequence of fpc_AnsiStr_Concat() calls (it
ignores empty strings to determine the result code page) and it's also
slower
* do not consider the run time code page of the destination string in
fpc_AnsiStr_Concat(_multi)() because Delphi does not do so either. This
was introduced in r19118, probably to hide another bug
+ test
git-svn-id: branches/cpstrrtl@25143 -
nadd.pas, taddnode:
+ add new constructor "create_internal" which adds "nf_internal" to the node's "flags"
* pass_typecheck_internal: allow pointer comparisons other than "=" and "<>" for nodes which have "nf_internal" set
psub.pas, generate_bodyentry_block:
* create the addnode using "create_internal" instead of "create" to allow the pointer comparison
+ added test

and if the result does not depend on the types of the arguments (to
prevent "qwordconst>int64const" being turned into
"int64(qwordconst)>int64const" and thereby potentially change the outcome)

try_make_mul32to64()
* when inserting a 32x32->64 multiplication, change the typeconversions
of the original nodes into internal type conversions, because they
may have been currency (e.g., in case of an integer-to-currency
conversion, which is performed via integer*currency(10000)) and
since r21097 implicit conversions from currency to ordinal are no
longer allowed

new ShortString->(Some)String precedence: ShortString, UTF8String, AnsiString, AnsiString(CodePage) and RawByteString, UnicodeString, WideString and other string types
new AnsiString->(Some)String precedence: RawByteString, UTF8String, AnsiString, AnsiString(CodePage), UnicodeString, WideString, ShortString and other string types
The new logic makes UTF8String more preferrable than other AnsiString types, AnsiString more preferrable than other AnsiStrings(codepage) and also makes UnicodeString more preferrable than WideString.
git-svn-id: trunk@21057 -
* created separate version of fpc_AnsiStr_Concat_multi() after all
because it contains a punicodechar(unicodestring) typecast, which
can't be supported on the JVM target (and splitting it out in the
generic code seems like a bit overkill), and restored original
generic version of fpc_AnsiStr_Concat_multi() (slightly faster
than version partially adapted for jvm)
git-svn-id: branches/jvmbackend@20903 -
o support for the new codepage-aware ansistrings in the jvm branch
o empty ansistrings are now always represented by a nil pointer rather than
by an empty string, because an empty string also has a code page which
can confuse code (although this will make ansistrings harder to use
in Java code)
o more string helpers code shared between the general and jvm rtl
o support for indexbyte/word in the jvm rtl (warning: first parameter
is an open array rather than an untyped parameter there, so
indexchar(pcharvar^,10,0) will be equivalent to
indexchar[pcharvar^],10,0) there, which is different from what is
intended; changing it to an untyped parameter wouldn't help though)
o default() support is not yet complete
o calling fpcres is currently broken due to limitations in
sysutils.executeprocess() regarding handling unix quoting and
the compiler using the same command lines for scripts and directly
calling external programs
o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
to the make command line

if expr1 has sideeffects. This can't be done safely even in case of
short boolean evaluation, because expr1 may return the inverse the
second time its called (and "0 or 1" is not the same as "0", and
neither is "1 and 0"), based on comment by Michael Karcher
* perform a full string compare when comparing stringconstnodes

git-svn-id: trunk@20485 -
- don't pass CP_NONE encoding to internal functions. They handled it as 0 encoding. This will optimize the generated code a bit.
- convert all king of string/char/pchar constants to local ansistring def if they needs to be passed to rawbytestring type. They should not get a CP_NONE codepage (delphi compatible)
- don't convert left and right arguments of string concatenation to ansistring type if they are already ansistrings but with different codepage - RTL already handles different codepages in concat routine
- fix resultdef for ansistring concatenations inside assignments - return def of left assignment operand if it is already ansistring - this reduces amount of unneeded condepage conversions since concat functions can return result in any desired codepage
rtl: remove CP_NONE comparisions from most of RTL functions, replace 0 constant with CP_ACP
tests: add test to check various conversions to RawByteString type
git-svn-id: trunk@19519 -
- add helper function getansistringcodepage which returns explicitly set codepage or 0 in other case
- add helper function getansistringdef which return a def with explicitly set codepage or cansistringtype in other case
- change tstoreddef.createnai constructor to allow set codepage in constructor
- don't convert string constants to rawbytestring. if string constant already has a codepage - preserve it or convert to ansistring codepage (delphi compatible)
- don't perform string conversion from ansistring to strings with explicitly set codepage (by directive or by compiler switch) and vice versa (delphi compatible)
+ test which covers most of the cases
