f6761d7939 * Handle safecall exceptions entirely in tcgtryfinallynode pass2. This simplifies things and removes the need in hidden safe_result variable.

a32fdc3ae6 + Added a simple helper tcg.g_call, intended to replace allocallcpuregisters+a_call_name+deallocallcpuregisters sequence which is used all over the place.
* 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).

9ed2fa6f7b - Exception handling: calling FPC_CATCHES(-1) is obsolete, it does not change any state and its return value is not used. Removed.
- Don't generate guard frame around 'except' block if it contains no code (tryexceptnode.t1 is an empty blocknode in this case).

0a3a62811b + try/except and try/finally support for JVM target:
o always create exceptvarsym entry for on-nodes (on all targets) to remove
     some special cases when an unnamed exception was caught
   o the JVM tryfinally node generates the finally code twice: once for the
     case where no exception occurs, and once when it does occur. The reason
     is that the JVM's static bytecode verification otherwise cannot prove
     that we will only reraise the caught exception when we caught one in
     the first place (the old "jsr" opcode to de-duplicate finally code
     is no longer used in JDK 1.6 because it suffered from the same problem,
     see Sun Java bug
     http://webcache.googleusercontent.com/search?q=cache:ZJFtvxuyhfMJ:bugs.sun.com/bugdatabase/view_bug.do%3Fbug_id%3D6491544 )

ad23569cf1 * renamed pi_has_goto into pi_has_label because the problematic thing is if a procedure has a label as target and not if it has some goto

283018a3bf * changed tprocdef.funcretloc[] from a tlocation into a tcgpara so it can
represent complex locations (required for full x86-64 ABI support,
    which is not yet implemented) -> lots of special result handling
    code has been removed and replaced by the parameter handling
    routines
  + added support for composite parameters (and hence function
    results) to tcg.a_load_ref_cgpara() (so it can be used for
    handling, e.g., 64 bit parameters on 32 bit platforms)
  * the above fixed writing past the end of allocated memory when
    handling records returned in registers on x86-64 whose size is
    not a multiple of 8 bytes (mantis #16357)
  - removed the x86-64 and PPC specific versions of a_load_ref_cgpara(),
    as they are now handled correctly by the generic version
  * moved the responsibility of allocating tcgpara cpu registers
    (using paramanager.allocparaloc()) from the callers of
    cg.a_load*_cgpara() to the cg.a_load*_cgpara() methods
    themselves (so the register allocation can be done efficiently
    when dealing with function results)
  * for the above, renamed paramanager.alloc/freeparaloc() to
    paramanager.alloc/freecgpara(), and use paramanager.allocparaloc()
    to allocate individual pcgparalocations instead
  * fixed the register size of SSE2 function result registers for
    x86-64 (when used for floating point), which results in removing
    a few superfluous "movs? %xmm0,%xmm0" instructions
  * fixed compilation of paramanagers of avr, m68k and mips after r13695
    and also updated them for these new changes

4838ebe73b * renamed mark_InlineStart/mark_InlineEnd to mark_NoLineinfoStart/
mark_NoLineinfoEnd
  * add "no line info" markers for try/except and try/finally internal cleanup
    code, so the debugger doesn't jump back and forth between the end and start
    of exception blocks when you arrive at the end

c1e327c8c4 * insert register allocation/deallocation information for the exception
handling code (g_exception_reason_load() now automatically allocates
    the cpu register that it loads). This fixes the bug reported in
    http://lists.freepascal.org/lists/fpc-devel/2009-May/016773.html
    on i386 with -O2)

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

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)
