356026f849 * use new_section() instead of tai_section.create() everywhere 
- sort of reverted r14134, which is no longer required after the above
    change (new_section() inserts the alignment itself)
  * made the tai_section.create() constructor private so it cannot be
    called directly anymore

3c8b23cda4 * fixed cg.a_loadmm_reg_ref() and cg.a_loadfpu_reg_ref() in case they are 
used to store a record function result in an MM/FPUREGISTER to memory
    (the register size will be OS_F32/OS_F64, while the memory size will
     be OS_32/OS_64 -> convert the latter to the former)
  * extended tcalext6 to also test this scenario

a7dca09535 * only refer to local symbols without GOT redirection on darwin/x86_64, 
because on linux/x86_64
     a) the resulting code crashes when using the internal assembler
     b) refuses to link when using the external assembler
   (and hence I don't know whether it's safe to do on other non-darwin
    platforms either) -- fixes mantis #15889

0c675a4039 * the objc1 unit has been renamed to objc 
* the objc unit links against the Foundation instead of against the Cocoa
    framework, and inludes an interface to either the fragile or non-fragile
    obj-c run time depending on the target platform
  + support for the non-fragile Objective-C runtime/ABI, as used on Mac OS X
    for ARM (iPhone) 64 bit (PowerPC/64, x86_64) -- all these targets now
    are now also supported for the objectivec1 modeswitch
  + support for private_extern symbol bindings, required for the above
  * mark objcclasses that are declared in the implementation section of a
    unit as "hidden" (not sure what the effect is, since the Objective-C
    runtime does not seem to do anything with this flag)
  * enabled all obj-c tests for the newly supported platforms

ec8fee45fe * do not access local data via the GOT on x86_64, because 
a) it's unnecessary
   b) it's slower than "direct" RIP-relative accessing
   c) it's not supported on darwin/x86_64 in certain cases
  * never use absolute addressing on darwin/x86_64 (like on win64)
  * when not generating PIC, make sure that a_loadaddr_ref_reg on x86_64
    also uses RIP-relative addressing for darwin/x86_64 and win64

baf1ac22b7 * fixed r13469 (PLT entries are not GOT-relative). Not reverting all the 
changes from that commit, because not hardcoding the use of
    current_procinfo in all cases when obtaining the GOT register is
    cleaner

92ad06f1e8 * Always use RIP relative symbol addressing for x86_64 Windows targets. Bug #13657.

7d459cf12a * the compiler now explicitly keeps track of the minimally guaranteed 
alignment for each memory reference (mantis #12137, and
    test/packages/fcl-registry/tregistry1.pp on sparc). This also
    enables better code generation for packed records in many cases.
  o several changes were made to the compiler to minimise the chances
    of accidentally forgetting to set the alignment of memory references
    in the future:
    - reference_reset*() now has an extra alignment parameter
    - location_reset() can now only be used for non LOC_(C)REFERENCE,
      use location_reset_ref() for those (split the tloc enum so the
      compiler can catch errors using range checking)

718694d1d6 * always specify an explicit alignment for tgobj.gettemp (so e.g. 
shortstring temps don't get maximum alignment)
  * changed some gettemptyed() calls into gettemp() calls (gettemptyped
    means that this temp can only be used for temps of that type,
    which is necessary for refcounted types but not for floats)

a23630260b + "weakexternal" support for imported procedures and variables. 
the syntax is exactly the same as for "external", except for
    the keyword. It is currently only active for Darwin targets.
    It should also work at least for Linux targets, but only with
    the GNU assembler (which is why it is not activated there)
  + test for this functionality

Jonas Maebe
f36e5411af * split cpu64bit compiler define into 
a) cpu64bitaddr, which means that we are generating a compiler which
       will generate code for targets with a 64 bit address space/abi
    b) cpu64bitalu, which means that we are generating a compiler which
       will generate code for a cpu with support for 64 bit integer
       operations (possibly running in a 32 bit address space, depending
       on the cpu64bitaddr define)
   All cpus which had cpu64bit set now have both the above defines set,
   and none of the 32 bit cpus have cpu64bitalu set (and none will
   compile with it currently)
  + pint and puint types, similar to aint/aword (not pword because that
    that conflicts with pword=^word)
  * several changes from aint/aword to pint/pword
  * some changes of tcgsize2size[OS_INT] to sizeof(pint)

8349cde7db * changed byte/word/longbool to be Delphi-compatible (+ similar changes 
for qwordbool) + test:
    o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
    o these types are now all signed
    o converting an integer type to a byte/word/long/qwordbool using an
      explicit type cast keeps the integer's original value stored in the
      bool, instead of forcing it to ord(true)/ord(false)
    (mantis #10233 and #10613, implemented for all architectures, testsuite
     tested for ppc32, sparc and x86)
  * fixed some places where the rtl depended on longbool(true) having the
    value 1
  * extended several boolean tests (and adapted some to no longer assume
    that byte/word/long/qwordbool(true)=1)
  + support for converting to qwordbool in second_int_to_bool for x86, ppc
    and sparc

    be called directly)

3266f4e483 + Compiler support for pic on darwin/i386. The i386 rtl still needs 
to be made pic-safe (mainly accesses to the global default8087cw)
  * At the same time also made the non-pic code abi-compliant (access
    external data via indirect symbol pointers etc)

    Darwin/i386 also puts the got into a virtual register (like
    Darwin/ppc), a.o. because the register allocator fails to colour
    a routine in aasmcpu.pas if we take away ebx from it.
