- 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

* Refactored code generation for tcgonnonde and tcgtryexceptnode, simplifying both compiler and generated code. Merged compilerprocs called in sequence into larger ones (fpc_popobjectstack+fpc_destroyexception -> fpc_doneexception, fpc_popsecondobjectstack+fpc_destroyexception+fpc_reraise -> fpc_raise_nested).

implementation (Delphi-compatible in case multiple overloads exist in
the current unit, and in other cases avoids compiler crashes in case
of circular implementation dependencies)
* ignore other symbol options (deprecated, legacy, platform, ...) as far as
the interface crc is concerned to avoid trouble in case they appear in the
implementation but not in the interface (to prevent compiler crashes)

platforms from testing for a Windows target into testing to the
tf_safecall_exceptions target flag. However, this flag was not set for
non-i386 Windows platforms (mantis #20385)

defcmp: Address code paged' string type comparison taking care of the code page
ncnv: Remove un-needed code page comparison to CP_UTF8, some fixes regarding shortstrings and wide char/string
ncon: For the case of tstringconstnode.changestringtype (ncon.pas) where the code page are of CP_NONE or 0 no translation is done as :
* CP_NONE is compatible to all
* For 0 the raw bytes are just copied.
My changes:
- change ascii2unicode to allow pass source codepage,
- convert in both cases when source or destination is UTF8

- Don't generate guard frame around 'except' block if it contains no code (tryexceptnode.t1 is an empty blocknode in this case).
git-svn-id: trunk@19415 -
* Don't generate rex.w for "CALL|JMP|LCALL|LJMP regmem", they are 64-bit by default.
* LCALL,LJMP flagged as calljump instructions.
* LCALL,LJMP encode only far jumps and don't accept register operands.
* GAS writer: fixed writing rip-relative operands of calljump instructions.
+ test.
git-svn-id: trunk@19413 -
* eliminate warnings in compiler (i386 & i368->x86_64) and minor refactorings
- comment out unused vars and types
- comment out unneeded comparisons (Longword <=> 0)
- suppress some "comparison always true|false" warnings
- tweak visiblity sections
