5b6e50c9da * It is incorrect to use var_align() in linker code: it depends on current_settings.alignment, which is valid only while compiling, not while linking. Replaced with size_2_align().

11b72b5515 x86_64 internal ELF linker: 
* Split generation of regular and TLSIE GOT entries. Although code for both is similar to some extent, mixing them in a single method turns it into spaghetti.
* Several fixes to content and dynamic relocations of TLSIE entries.

70dda94474 * x86_64-win64: don't allocate outgoing parameter area in nostackframe procedures, it fails compilation if range/overflow/etc checking is enabled (which always sets pi_do_call) due to check introduced in r22677.

53ea24a0b1 Correctly specialize generics if locally declared types are used (e.g. two procedures could both define a different "TRec" type which is used to specialize a generic inside the procedures). 
symtype.pas, tdef:
  + add method "fullownerhierarchyname" which allows to retrieve the owner hierarchy name including procedure/function/method names
  + add method "fulltypename" which uses "fullownerhierarchyname" to return a full type name
symdef.pas, tstoreddef:
  * implement "fullownerhierarchyname" (including caching of the result)
pgenutil.pas, parse_generic_specialization_types_internal:
  * use "tdef.fulltypename" instead of "tdef.typename" to have unique values for each parsed type and thus for the specialization itself

+ tests

404c3efa58 * MIPS: handle get_frame internally, so it sets pi_needs_stackframe flag on current procedure. This makes possible not to force pi_needs_stackframe on every procedure and thus omit saving/restoring $fp register when it is not necessary.

35b771e421 * previously, we preferred pchar->shortstring to pchar->ansistring in 
case of {$h-}. Now this is no longer done because it caused
    pchar->ansistring and pchar->unicodestring to have the same
    overload preference, which regularly caused problems with the
    added unicodestring overloads in the RTL in the cpstrrtl branch.
  * fixed tw3328.pp (it was missing a {$mode delphi}), which failed
    before this patch but compiles new
  + extra variants of that test for the compiler changes

9494fadf08 * MIPS: set pi_do_call flag for assembler procedures with stackframes, so in PIC mode it further receives pi_needs_got in PIC mode and allocates the GP save temp. 
* Deallocate GP save temp in epilogue to avoid warnings when compiled with -dEXTDEBUG
* g_concatcopy: don't check alignment, this allows single byte or word locations to be copied with 2 instructions. Larger unaligned references are supposed to be handled in g_concatcopy_unaligned instead.

1ca2a253e8 MIPS, improved integer to real conversions: 
* Use fpc_[int64|qword]_to_double instead of [int64|qword]_to_float64, makes RTL no longer dependent on softfloat code.
* Move 32-bit values from integer registers to FPU registers without using memory.
* Fixed branching, was still using a macro and delay slot was missing.

fc79d47b09 Fix for Mantis #24651. Allow pointer comparison for internal expressions (in this case check for valid VMT). 
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

407e9d173b Fix for Mantis #17598. When extended syntax is off allow the result of constructors to be dropped when the constructor is called as an instance method instead of a class method. 
pstatmnt.pas, statement:
  * check whether the constructor is called as an instance or class method
nflw.pas, tlabelnode.pass_1:
  * don't check the owner of the labelsym when there is none (happens with internally created labels like for e.g. exception handling)

f3a1c749fb * tcgtypeconvnode.second_int_to_int: reuse 8 and 16-bit-sized register locations on targets with 32-bit-only registers when casting to larger size (except ShortInt to Word cast). This is possible because upper bits of such registers are always kept valid by code generators (see 'maybeadjustresult' method in cgcpu.pas). Removes a lot of useless register moves.

9e4cc57768 * MIPS: handle 8 and 16-bit arithmetic shifts internally, by shifting argument left by 24/16 bits, followed with 32-bit arithmetic shift right by appropriately adjusted amount.

1c84c3edbf * Fixed label optimizer to work with MIPS, and enabled level 1 optimization for MIPS targets. 
The difference in branch instruction formats is isolated in function JumpTargetOp, it is a plain function rather than a virtual method, so it can be easily inlined and, after inlining, produces the same code for non-MIPS targets as it was before change.
