701cdf8ea2 * fix for #25956: left is not necessarily the array load node when accessing an open array/array of const element 
git-svn-id: trunk@27487 -

8d1ed088c8 + implemented far pointer arithmetic (operating only on the offset, without 
touching the segment)

198960b17c * preserve the segment of the reference in tx86vecnode.update_reference_reg_mul 
on i386 and x86_64 as well

f00f7d6ee7 * override tcgvecnode.update_reference_reg_mul for i8086 and add code that 
preserves the reference segment (because reference_reset_base, which is
  sometimes used by the base method, kills the segment)

7a873f495d * use the stack segment for SP-relative addresses in Tcgx86.g_concatcopy in 
the memory models with SS<>DS (necessary, because make_simple_ref isn't called
  in the copy_string case)

5c48804240 * Moved local label infrastructure into tasmreader, reduces number of global vars. Functionality is not changed.

ee20ecfcf2 * tcgx86.make_simple_ref: in i8086 memory models with DS<>SS, add an SS: segment 
override when converting SP-relative references to use a general purpose
  register

adc8cdb5af * Calling tlabelsym.mangledname should not define the label. This was causing "already defined" errors if a label was referenced before it was defined. 
+ Test.
+ Check duplicate labels in assembler blocks. This was impossible due to above bug and duplicate labels were detected only at assembling stage where no location information could be provided.

e43791cf7c * ti8086callnode.extra_call_ref_code: do not change the base register to BX if 
it's BP, because that breaks memory models with DS<>SS

8ae36f3ef4 tstaticvarsym.ppuload: read the section string outside of the symansistr define to match the code of ppuwrite

5c1b8fdad9 Fix for Mantis #19697. For this we need to have the internal static var symbol know that it came from a static field var symbol so that we can check that for generic or not. 
symsym.pas, tfieldvarsym:
  + add new field fieldvarsym which holds a reference to a tfieldvarsym if the static sym was created based on such a symbol
  + add necessary methods and code to correctly load from and store to PPU
  + add new constructor create_from_fieldvar
symcreat.pas, make_field_static: 
  * use new create_from_fieldvar constructor instead of the default one
hlcgobj.pas, finalize_static_data:
  * check whether the static var is based on a generic's class var
ppu.pas:
  * increase PPU version

+ added test

b9a59c33f4 Fix for Mantis #25915. 
* ptype.pas, id_type:
    generate the "identifier not found" message only if the identifier was really not found and not when the identifier is a non-type
* pexpr.pas, statement_syssym: 
    don't generate the "type id expected" error message for Default() anymore; this is already handled by single_type

+ added test (though this again will not help much as output is not parsed...)

689996d84f Fix for Mantis #25959. 
* pdecsub.pas, parse_proc_direc:
    when a hint directive is parsed we need to check whether the new token can still be a directive

+ added test (though that won't help much as we don't check the compiler output yet... :/ )

e9e4cc8bcb * Tcgx86.g_concatcopy: use boolean variables saved_ds and saved_es to keep track 
whether these segment registers were saved on the stack or not

96dd464bf2 * Moved fixup_jmps to target-specific classes for powerpc,powerpc64 and MIPS, cleaned out remaining $ifdef's. A slight functionality change is that fixup_jmps is now called before adding the procedure end symbol, not after, but that should not matter.

9c7c64a3af * moved amiga/morphos-specific libsym-related field from tprocdef to 
cpu-specific descendants (unfortunately causes some duplication, but the
    code is trivial and there is no easy way to avoid it)
  * also moved the use of the field in ncal to cpu-specific files (with same
    caveat)

8c693a3300 * Win64 apparently expects records with single field of floating-point type to be passed the same way as that only field, i.e. in xmm register. Fixes tests/cg/tcalext6.pp.

68b97bee5a * ARM: Implemented floating-point negation and abs() for softfloat using integer instructions. Fixes webtbs/tw4534.pp, and also yields much faster code than existing implementation. 
Background: these operations are defined as flipping or clearing the upper bit of number, respectively, and never result in precision loss or raise floating-point exceptions.
